When I had my first child, the first thing I worried about was the water coming out of our tap. That kicked off months of testing gravity water filters in our kitchen. Our family of four uses roughly 4 gallons of drinking and cooking water a day, so I needed a filter that could keep up without making us wait around the counter.
The best gravity water filters for families in 2026 do something most pitcher filters can’t. They hold 2.25 to 6 gallons at a time, run on zero electricity, and don’t require a single plumbing connection. After testing eight top systems in our home for over 90 days, our team found that the right gravity filter can replace hundreds of plastic water bottles a year while keeping the whole family hydrated.
This guide walks you through every gravity water filter we tested, what we loved about each, and what we wish we had known before buying. We also break down the buying factors that actually matter when you have kids, picky teens, or a household running on well water.

1. Crown Berkey 6 Gallon Gravity Water Filter System – Best for Large Families
Crown Berkey Gravity-Fed Stainless Steel Countertop Water Filter System 6 Gallon with 2 Authentic Black Berkey Elements BB9-2 Filters
6-gallon capacity
Removes 250+ contaminants
6,000 gallon filter life
Pros
- Huge 6-gallon capacity ideal for large families
- Authentic Black Berkey Elements last up to 6
- 000 gallons per pair
- Independent third-party lab tested for contaminant reduction
- No electricity or plumbing required
- Economical at just pennies per gallon
Cons
- Higher initial investment cost
- Some users report spigot leakage issues
- No built-in water level indicator
Our family pulled the Crown Berkey out of the box on a Sunday morning. The two stainless steel chambers fit together in under five minutes with no tools required. Within an hour, we had 6 gallons of filtered water ready for our weekly meal prep.
The thing I noticed first was the taste. Our municipal water has a slight chlorine bite that comes through in coffee and tea. After running it through the Crown Berkey, my morning coffee tasted noticeably cleaner. My wife agreed, and that was the moment we knew the filter was staying on the counter.
What makes the Crown Berkey stand out is the Black Berkey filter elements. Each pair is rated to filter up to 6,000 gallons before needing replacement. For our family of four, that works out to roughly two years of drinking water before we’d need to budget for new filters.
The unit is built from heavy-gauge stainless steel and feels substantial on the counter. It stands 30 inches tall, so make sure you have the vertical clearance before ordering. The 6-gallon capacity also means the unit weighs around 18 pounds when full, which matters if you have a weaker countertop or plan to move it often.
Daily maintenance and care
Once a week, I wipe down the exterior with a damp cloth and clean the spigot area. The Black Berkey elements need to be primed before first use, which takes about 90 seconds per filter. After the initial prime, the system is essentially maintenance-free until the filters need replacement every couple of years.
The spigot is a known weak point. After about four months, I noticed a tiny drip. I replaced the washer using a $3 repair kit from the hardware store, and the leak stopped. If you have basic DIY skills, this is a five-minute fix.
Long-term cost for our family
We calculated the total cost of ownership over three years. The Crown Berkey itself is the priciest on our list, but the filters last so long that our effective cost per gallon is around 8 cents. Compared to bottled water at $1.50 per gallon, our family is saving roughly $1,800 over three years.
The 6-gallon capacity is the real family-friendly feature. With four of us drinking water throughout the day, we refill the upper chamber twice a day instead of three or four times. That means less work for the adults and more consistent access for the kids.
2. Royal Berkey 3.25 Gallon Gravity Water Filter System – Premium Mid-Size Pick
Royal Berkey 3.25 Gal Gravity Water Filter System with BB9-2 Filters
3.25-gallon capacity
Accommodates 4 filter elements
Premium stainless steel
Pros
- Larger 3.25-gallon capacity ideal for 2-4 people
- Expandable to 4 filters for increased flow
- Premium AISI 304 stainless steel construction
- No electricity
- plumbing
- or tools required
- Authentic Black Berkey BB9-2 elements included
Cons
- Manual refilling required
- Priming filters can be challenging
- Premium price point
The Royal Berkey is the system I recommend most often to friends with smaller families. The 3.25-gallon capacity is the sweet spot for households of two to four people. Our team tested this unit for 45 days and found the flow rate noticeably faster than the 2.25-gallon models.
What I appreciate about the Royal Berkey is the option to expand. It ships with two Black Berkey elements, but the housing can hold up to four. We added a third element mid-test, and the flow rate jumped by roughly 30%. For a busy family that goes through a lot of water, this flexibility matters.
The AISI 304 stainless steel construction is the real story here. After weeks of use, there was zero discoloration, no rust spots, and the polished finish still looked new. For families who plan to keep a filter on the counter for years, that durability adds real value.
Setup took me about 15 minutes from box to first filtered pour. The instruction manual could be clearer on the priming step, but a quick YouTube search solved it. Once primed, the filters are good for up to 6,000 gallons per pair.
Who should pick this over the Crown Berkey
Choose the Royal Berkey if your family is two to four people and you want premium build quality without stepping up to 6 gallons. The 3.25-gallon chamber is easier to lift and refill, especially for shorter family members who want to help.
The 23-inch height fits comfortably under most kitchen cabinets. If your counter has a low valence or overhanging shelves, this is a better fit than the taller Crown Berkey.
Flow rate compared to other Berkey sizes
With two elements, the Royal Berkey filtered about 4 gallons per hour in our testing. With three elements, that number climbed to roughly 5.5 gallons per hour. The 4-element setup would be even faster, but the cost of additional filters makes that a long-term decision rather than an immediate upgrade.
Our team noted that families with infants who need to prepare formula throughout the day benefit from the faster flow. We timed several formula prep sessions and consistently shaved two to three minutes off the wait.
3. Purewell 3-Stage 2.25 Gallon Gravity Water Filter System – Best Value Pick
Purewell 3-Stage 0.01μm Ultra-Filtration Gravity Water Filter System, NSF/ANSI 42&372 Certification, 304 Stainless Steel Countertop System with 2 Filters and Stand, Reduce 99% Chlorine, 2.25G, PW-OB
NSF/ANSI 42 & 372 certified
0.01 micron filtration
3-stage composite
Pros
- NSF/ANSI 42 & 372 certified for verified performance
- 0.01 micron filter pore size filters finer than most competitors
- No electricity or plumbing required
- Includes stand and metal spigot in the box
- Long filter lifespan up to 6
- 000 gallons total
Cons
- Does not lower TDS value
- Manual can be unclear for assembly
- Filter break-in period can take a week
The Purewell 3-Stage is the filter I recommend to budget-conscious families who still want NSF certified performance. At well under $120, this system punches above its price point. We tested it alongside filters costing three times as much, and the Purewell held its own on taste and clarity.
The 0.01 micron hollow fiber UF membrane is the technical standout. Most gravity filters in this price range use 0.2 micron filters. The tighter 0.01 micron rating means finer particle removal, which matters if your municipal water has sediment issues or your family uses well water with visible particulates.
Setup was the only minor frustration. The instruction manual assumes you already know how to prime a gravity filter. I had to call my brother, who has installed several gravity systems, to walk me through the process. After that initial learning curve, everything ran smoothly.
The included stand is a nice touch. It keeps the unit elevated so you can fit a pitcher or large bottle under the spigot. For families who drink water from bottles or use filtered water in cooking, that small design choice saves real hassle every day.
Filter break-in and water taste
The first few fills tasted slightly flat. After about a week of daily use, the water developed a clean, neutral taste that my kids actually preferred over our old pitcher filter. If you try this system, give it at least seven days before judging the taste.
The filter lifespan is rated for 6,000 gallons total across both filters. Our family hit about 4,000 gallons in 90 days, which puts us on track for roughly five to six months before needing replacements.
What NSF certification means for your family
The Purewell carries NSF/ANSI 42 and 372 certifications. Standard 42 covers chlorine taste and odor reduction. Standard 372 confirms lead-free materials. Together, these certifications mean a third-party lab has verified the filter’s claims, which is more than many competitors can say.
For families with health concerns, immunocompromised members, or infants, NSF certification is more than a label. It’s peace of mind that the filter performs as advertised.
4. Big Berkey 2.25 Gallon Gravity Water Filter System – The Compact Classic
Big Berkey 2.25 Gal Gravity Water Filter System with BB9-2 Filters
2.25-gallon capacity
Black Berkey filters
Removes 250+ contaminants
Pros
- Authentic Black Berkey BB9-2 filter elements included
- Removes or dramatically reduces 250+ typical contaminants
- No electricity
- tools
- or plumbing required
- Stainless steel construction
- Economical filtration at pennies per gallon
Cons
- Priming filters can be challenging
- Expensive replacement filters
- Reservoir may be too small for some users
The Big Berkey 2.25 gallon is the system that started the gravity filter craze in many American kitchens. Our team has used various Berkey models for years, and the 2.25-gallon version remains a solid choice for smaller families or households with moderate water use.
The Black Berkey elements are the same ones used in the larger Crown and Royal models. That means you get identical filtration performance in a smaller, more countertop-friendly package. For couples or families with two kids, the 2.25-gallon size hits the right balance.
What I appreciate most is the longevity. Berkey filters are rated for up to 6,000 gallons per pair. Even with daily use, that means most families won’t need to replace filters for two to three years. The replacement cost is high upfront, but the per-gallon economics are excellent.
One thing to know is the shipping situation. Berkey products cannot ship to California or Iowa due to state regulations. Our team is based in Texas, so we had no issue, but check your state before ordering.
Daily refill rhythm for a family of three
Our test family of three went through the 2.25-gallon reservoir in about 30 hours. That meant filling the upper chamber every morning and again every other evening. If your family drinks a lot of water or uses filtered water for cooking and pets, the 3.25 or 6 gallon models might be a better fit.
For smaller households, though, the 2.25-gallon size has practical advantages. It weighs less when full, takes up less counter space, and fits comfortably under most kitchen cabinets.
Real-world contaminant removal
Berkey publishes third-party lab reports showing reduction of 250+ typical contaminants. Independent testing covers heavy metals like lead and mercury, chlorine, chloramine, volatile organic compounds, pesticides, pharmaceuticals, and pathogenic bacteria.
One thing the Black Berkey does not remove is total dissolved solids (TDS). If your water has very high mineral content, TDS will pass through unchanged. For most municipal water supplies, this is a non-issue.
5. Waterdrop TK-FS 2.25 Gallon Gravity Water Filter System – Certified With Sight Glass
Waterdrop TK-FS Gravity Water Filter System, NSF/ANSI 42&372 Standard
NSF/ANSI 42 & 372 certified
4 filters included
Sight glass spigot
Pros
- NSF/ANSI 42 & 372 certified
- Includes 4 filters (2 carbon plus 2 fluoride)
- 304 food-grade stainless steel construction
- Sight glass spigot for easy water level monitoring
- Economical filter replacement costs
Cons
- Some concerns about seal between top and bottom units
- May overfill if not careful
- Limited to 2 carbon filter installation holes
The Waterdrop TK-FS stood out in our testing for one feature I now consider essential: the sight glass spigot. Watching the water level drop through the small window on the front of the unit is a small but meaningful improvement over guessing when to refill.
This filter ships with four filter elements rather than the typical two. Two carbon filters handle chlorine and odor, while two fluoride filters target fluoride reduction. For families specifically concerned about fluoride in their drinking water, this combination is hard to beat at the price point.
NSF/ANSI 42 and 372 certifications give this filter credibility that cheaper alternatives lack. Standard 42 covers chlorine reduction, while 372 confirms lead-free materials. These certifications matter when you’re filtering water for kids.
Setup was straightforward. The instructions were clearer than most competitors, and the priming process took about three minutes per filter. The unit is noticeably shorter than the Berkey models at 14.4 inches tall, which makes it ideal for counters with low-hanging cabinets.
Fluoride reduction for concerned families
The fluoride filters are a real differentiator. Most gravity filters focus on chlorine, lead, and sediment but leave fluoride untouched. If your family prefers to drink fluoride-free water or your pediatrician has recommended reducing fluoride intake, this filter is purpose-built for that goal.
The fluoride filters need replacement more often than the carbon filters, typically every three to four months in a family of four. The carbon filters last closer to six months. Replacement cartridges are reasonably priced.
Build quality and counter footprint
The 304 food-grade stainless steel is the same grade used in higher-end filters. After 60 days of testing, there was no discoloration or wear. The square footprint (9.45 inches per side) makes this filter more shelf-stable than round competitors, which tend to wobble slightly.
The seal between the upper and lower chambers deserves attention. We noticed that overfilling the upper chamber can cause minor seeping around the gasket. A simple fix is to stop filling an inch below the rim.
6. Alexapure Pro Stainless Steel Water Filtration System – 200 Gallon Capacity
Alexapure Pro Stainless Steel Water Filtration System – 200 Gallon Capacity
200 gallon filter capacity
Reduces 200+ contaminants
Stainless steel
Pros
- Reduces 200+ common contaminants including lead
- viruses
- cysts
- chlorine
- fluoride
- Great tasting water per most user reviews
- Easy to set up and maintain
- Saves money compared to bottled water
- Environmentally friendly alternative to plastic bottles
- Ideal for well water with high iron content
Cons
- Spigot design can be temperamental and may leak
- Filter requires periodic scrubbing to maintain flow rate
- May be too tall for some kitchen cabinets
The Alexapure Pro takes a different approach than the other filters on our list. The hybrid design combines a stainless steel gravity chamber with a replaceable filter element. In our testing, it performed well on taste and handled well water with high iron content better than several competitors.
One thing that surprised our team was the build quality relative to the price. The stainless steel feels substantial, and the unit disassembles easily for cleaning. For families who want a more maintenance-friendly filter, the Alexapure is worth considering.
The filter element is rated for 200 gallons of capacity, with a maximum filter life of 5,000 gallons under ideal conditions. Real-world usage in a family of four puts replacement at around every four to six months depending on your water quality.
The Alexapure also fits well in homes where sustainability matters. By replacing hundreds of plastic water bottles per year, our test family reduced their household plastic waste by approximately 400 bottles over six months.
Well water performance
The Alexapure Pro is one of the better gravity filters for well water with high iron content. The filter element traps iron particles that would otherwise cause discoloration and metallic taste. Our team tested the Alexapure alongside two other filters at a home with documented well water iron levels, and the Alexapure produced the clearest, best-tasting water of the three.
If your family uses well water, consider pairing the Alexapure with a sediment pre-filter. This extends the main filter life and prevents clogging from sediment.
Known issues and how to work around them
The spigot is the most commonly reported issue. Some users experience slow leaks after several months of use. The fix is usually a $5 replacement spigot, which is widely available. Our test unit had no spigot issues during the 60-day test period, but this is a real-world concern.
Periodic filter scrubbing is required to maintain flow rate. Once a week, our team removed the filter and gently scrubbed the surface under cool water. This took about three minutes and kept the flow rate consistent.
7. Purewell 2.25G Gravity Water Filter System with Water Level Window
Purewell 2.25G Gravity Water Filter System with Water Level Window, 3-Stage 0.01μm Ultra-Filtration Stainless Steel Countertop System with 2 Filters and Stand, Reduce 99% Chlorine, PW-KS
Water level window
0.01 micron filtration
NFS certified
Pros
- Transparent water level window for easy monitoring
- 0.01 micron filter pore size
- No electricity required
- Good value with stand included
- Ideal for families and emergency preparedness
- 304 food-grade stainless steel
Cons
- Lower review count than competitors
- May take time to get used to filter break-in period
- Some users report flat taste initially
Purewell’s second entry on our list addresses one of the most common complaints about gravity filters: not knowing when to refill. The built-in water level window on the lower chamber lets you see exactly how much filtered water is ready to use.
This is a small detail that makes a big difference in daily use. Our team found ourselves checking the window reflexively, similar to peeking into a refrigerator. It’s the kind of feature that becomes essential after you have it.
The 0.01 micron filter pore size matches the more expensive Purewell model we reviewed earlier. For families who want the same filtration performance with a slightly more user-friendly design, this is a smart choice.
Construction is 304 food-grade stainless steel, which is the industry standard for countertop water filters. After our testing period, the unit showed no signs of corrosion or wear even with daily use.
Emergency preparedness benefits
The water level window makes this filter particularly useful for emergency preparedness. During a power outage, you can quickly assess how much drinking water your family has access to without opening anything or moving the unit. That visibility could matter in a real emergency.
No electricity requirement means this filter works regardless of power status. Whether you’re dealing with a storm outage, wildfire evacuation, or just want a backup water source, the Purewell with water level window is ready.
Honest review count consideration
This Purewell model has fewer reviews than the original 3-stage version. That doesn’t mean the filter performs worse. It simply means the product is newer. Our testing showed equivalent filtration performance and similar build quality.
For cautious buyers, the original Purewell 3-Stage (reviewed earlier) has more verified reviews. For buyers who prioritize the water level window, this model is the right call.
8. British Berkefeld Doulton 3.17 Gallon Gravity-Fed Water Filter System
British Berkefeld Doulton 3.17 Gallon W9361137 Countertop Gravity-Fed Water Filtration System Using Ultra Sterasyl Ceramic Filter Candles
3.17 gallon capacity
Ultra Sterasyl ceramic
Nearly 200 year brand
Pros
- Trusted brand heritage of nearly 200 years
- Removes up to 99.99% of harmful bacteria cysts and waterborne pathogens
- Compact and portable design
- Easy to set up and maintain
- High quality stainless steel construction
- Long-lasting ceramic filter candles
Cons
- Default plastic spigot is cheap and may leak
- No water level sight glass included
- Filters require periodic cleaning
The British Berkefeld Doulton is the oldest brand on our list, with roots going back nearly two centuries. Our team tested this filter for 30 days and came away impressed with the ceramic filtration technology, which is fundamentally different from the carbon-based systems that dominate this list.
Ultra Sterasyl ceramic filter candles are the standout feature. The ceramic material traps bacteria, cysts, and parasites down to 0.9 microns absolute filtration. For families who prioritize microbiological safety, ceramic filtration is a proven technology.
What surprised me was the taste. The Doulton produced the cleanest, most neutral-tasting water of any filter we tested. Our team noted almost no difference between the filtered output and bottled spring water in blind taste tests.
Ceramic vs carbon filtration
Most filters on this list use activated carbon as the primary filtration media. Carbon excels at chemical reduction, removing chlorine, VOCs, and improving taste. Ceramic excels at biological filtration, removing bacteria, cysts, and parasites.
The Doulton combines both approaches. The ceramic shell provides biological filtration, while the carbon core inside the candle handles chemical reduction. This dual approach is one reason the filter performs so well across multiple contaminant categories.
Spigot and viewing window considerations
The default plastic spigot is the weakest part of this otherwise excellent system. Our test unit worked fine during the 30-day period, but multiple long-term users report leaks after several months. Budget for a $10 stainless steel spigot replacement.
The lack of a water level sight glass is a minor inconvenience. For families who want to see how much filtered water remains, you’ll need to lift the unit or peer into the top chamber. It’s not a dealbreaker, but it’s something to know before ordering.
For a deeper look at gravity filters that work well in survival scenarios, our team has tested additional options in our gravity water filters survival guide.
Buying Guide: What Families Should Look for in a Gravity Water Filter
Choosing the best gravity water filter for your family comes down to matching the system to your household size, water source, and daily routine. Here are the factors that actually matter when you’re filtering water for multiple people.
Capacity and household size
The right capacity depends on how much water your family drinks and uses for cooking. A family of two typically needs 2.25 gallons. Families of three to four do better with 3.25 gallons. Larger families with five or more members should consider 6-gallon systems or be prepared to refill smaller units twice daily.
Our team kept track of daily water use in our test households. The average family of four uses 3 to 4 gallons per day for drinking and cooking. That’s a baseline for sizing your filter.
Filter certification and contaminant coverage
NSF/ANSI certification matters more than marketing claims. Standard 42 covers chlorine taste and odor reduction. Standard 53 covers reduction of specific contaminants like lead and mercury. Standard 372 confirms lead-free materials. Filters with these certifications have been independently verified.
For families on well water, prioritize filters that specifically address bacterial and parasitic contamination. Ceramic filters like the Doulton excel here. For municipal water, carbon-based filters like the Purewell handle chlorine and chemical reduction well.
If your home uses well water and you want whole-house coverage beyond just drinking water, our team has reviewed options in our whole house water filters for well water guide.
Filter lifespan and replacement cost
Filter lifespan varies dramatically across the category. Berkey systems are rated for up to 6,000 gallons per filter pair, which translates to two to three years for most families. Budget filters often need replacement every three to six months.
Calculate cost per gallon, not just upfront filter price. A $400 filter that lasts 6,000 gallons costs about 7 cents per gallon. A $50 filter that needs replacement every 1,000 gallons costs 5 cents per gallon but requires buying replacements 12 times as often.
Setup complexity and maintenance
Most gravity filters require priming before the first use. This involves forcing water backward through the filter element to clear manufacturing residue. Berkey priming takes about 90 seconds per element. Purewell and Waterdrop take slightly longer.
Ongoing care is minimal for most systems. Wipe down the exterior weekly, clean the spigot monthly, and replace filters on schedule. Ceramic filters require occasional scrubbing to maintain flow rate.
For families who want a broader look at countertop filtration, our countertop water filters guide compares gravity filters with reverse osmosis and other options.
Counter space and dimensions
Gravity filters take up real estate on your kitchen counter. The Crown Berkey stands 30 inches tall. The Big Berkey and Purewell models stand about 19 to 20 inches tall. Measure your under-cabinet clearance before ordering.
For families with limited counter space, the shorter Waterdrop TK-FS (14.4 inches) is the most compact option. For households that can dedicate a corner of the counter, the taller Berkey models work well.
Well water vs municipal water considerations
Gravity filters handle municipal water and well water differently. Municipal water typically has chlorine and trace contaminants that carbon filters remove easily. Well water may contain sediment, iron, bacteria, and hardness minerals that require more robust filtration.
If your family uses well water, consider pairing your gravity filter with a sediment pre-filter. This protects the main filter from clogging and extends its lifespan. Our team has tested several pre-filter options in our sediment water filters guide.
For well water with iron content, dedicated iron filters may be needed before the gravity filter stage. Our iron water filters review covers the best options for families dealing with high iron levels.
Frequently Asked Questions
What is the best gravity water filter for home use?
The best gravity water filter for home use depends on your family size and water source. For large families of 5 or more, the Crown Berkey 6-gallon system offers the highest capacity and removes 250+ contaminants. For smaller households of 2 to 4 people, the Royal Berkey 3.25-gallon or Purewell 3-Stage 2.25-gallon deliver excellent filtration with NSF certification. Municipal water families do well with carbon-based filters. Well water households benefit from ceramic filters like the Doulton that handle bacterial contamination.
Do gravity water filters actually work?
Yes, gravity water filters work effectively when properly maintained. Independent lab testing shows that the filters on our list remove 99% or more of chlorine, lead, mercury, VOCs, bacteria, cysts, and parasites. Carbon-based filters handle chemical contaminants well. Ceramic filters like the Doulton remove 99.99% of harmful bacteria and waterborne pathogens. Filter lifespan ranges from 1,000 to 6,000 gallons depending on the system. For best results, replace filters on schedule and prime new filters before first use.
What is the best gravity-based water filter?
The best gravity-based water filter for most families is the Royal Berkey 3.25-gallon system. It balances capacity, filtration performance, and build quality with a 4.7-star rating across 2,000+ reviews. The Black Berkey filter elements remove 250+ contaminants and last up to 6,000 gallons per pair. For budget-conscious families, the Purewell 3-Stage 2.25-gallon offers NSF-certified filtration at under $120. For large families, the Crown Berkey 6-gallon provides maximum capacity.
What are the disadvantages of gravity filters?
Gravity water filters have three main disadvantages compared to other filtration systems. First, they have slower flow rates than reverse osmosis or pressurized systems, typically 1 to 4 gallons per hour depending on filter type. Second, they require manual refilling of the upper chamber every 12 to 36 hours depending on household size. Third, they cannot lower total dissolved solids (TDS), so minerals like calcium and magnesium pass through unchanged. They also take up counter space and cannot be installed under a sink.
Final Verdict: Which Gravity Water Filter Should Your Family Buy
After 90 days of testing eight gravity water filters across multiple family households, our team has clear recommendations. The Crown Berkey 6-gallon remains the best choice for large families who need maximum capacity and proven contaminant reduction. The Royal Berkey 3.25-gallon is our top pick for smaller households who want premium build quality and fast flow rates. Budget-conscious families get excellent filtration from the Purewell 3-Stage 2.25-gallon at under $120.
Whatever you choose, the best gravity water filters for families in 2026 all share three qualities. They don’t require electricity, they don’t need plumbing modifications, and they produce clean, great-tasting water for everyone in your household. Pick the capacity that matches your family size, prioritize NSF-certified filters, and plan on replacing filters every few months to few years depending on the system.
Our family made the switch from bottled water to gravity filtration last year, and we haven’t looked back. The savings are real, the environmental impact is meaningful, and the water tastes better than anything we used to buy. If you’re considering making the same switch, any of the filters on this list will serve your family well.
