The Purewell 3-Stage Gravity Filter is a non-electric countertop system with a 2.25-gallon capacity, two filters and a stainless steel stand. Its composite filters include a 0.01-micron hollow-fiber UF membrane, but Purewell says they do not lower TDS.
It may suit you if you want gravity filtration and can follow a six-month replacement schedule. Consider the Culligan MaxClear if its stated microplastics, lead and Total PFAS reduction claims match your priorities, or compare the best stainless steel gravity water filters for more options.
What does the Purewell 3-Stage Gravity Filter include?
The Purewell system comes with upper and lower chambers, a spigot, two filters and a stand. Its housing and spigot are stainless steel, and gravity moves water from the upper chamber into the lower one.
Purewell 3-Stage Gravity Filter: Best for compact countertop gravity filtration
- 2.25-gallon capacity
- 304 stainless steel housing
- Two filters included
- No electricity required
A 2.25-gallon stainless steel system with two composite filters and a stand. Its gravity-fed design needs no electricity, while its filters do not lower TDS.
Pros
- Two filters and a stand are included
- 304 stainless steel housing and spigot
- No electricity required
- Purewell says each filter can provide up to 3,000 gallons
Cons
- Filter life varies with water quality
- Filters do not lower TDS
- The upper chamber can leak if filled while the lower chamber is full
Purewell describes a composite filtration design with a hollow-fiber UF membrane, a silver ion membrane and an activated carbon block. Purewell says its black carbon filter has NSF/ANSI 42 certification and the system has NSF/ANSI 372 certification.
Purewell says the filters can reduce chlorine and intercept rust, sediment, organic matter and heavy metals. These are manufacturer claims, and they do not mean the system addresses every contaminant in your water.
How does the three-stage filter work?
The filter combines three media types in one composite element, rather than using three separate chambers. Its listed methods are activated carbon, silver ion and a hollow-fiber UF membrane.
Purewell gives the membrane a 0.01-micron pore size and says the system can maintain a flow rate of 4 gallons per hour. Your water conditions and filter condition can affect how quickly the lower chamber fills.
The system does not lower TDS, according to Purewell. If dissolved solids are your main concern, compare technologies in our guide to countertop water filter systems, including reverse osmosis.
Who is the Purewell gravity filter best for?
The Purewell suits people who want a 2.25-gallon countertop unit without power or plumbing. Its included stand, spigot and two filters make it a ready-to-assemble gravity setup.
It can also work where you want to avoid a permanent installation. Purewell says the system can be used indoors or outdoors.
The capacity is not a measure of how much water is ready at once. Gravity filtration takes time to move water into the lower chamber.
Choose a different approach if your main requirement is lowering TDS or if you want a filter with a certification claim for a specific contaminant. Our guide to what gravity water filter labels mean explains why the exact claim matters.
How much space does the Purewell need?
The Purewell measures 8.9 inches wide and 20 inches tall. Leave room above the upper chamber for refilling and enough clearance to remove the top chamber for cleaning.
| Detail | Purewell 3-Stage Gravity Filter |
|---|---|
| Capacity | 2.25 gallons |
| Dimensions | 8.9 x 8.9 x 20 in |
| Weight | 8.5 lb |
| Housing material | Polypropylene and stainless steel |
| Filter method | Activated carbon, silver ion and hollow-fiber UF membrane |
| Power | Non-electric |
| Included | Upper chamber, lower chamber, spigot, two filters and stand |
| Filter life guidance | Replace every 6 months for optimum performance |
Measure the counter where you plan to place it, including the height under cabinets. Its 20-inch height can make low shelves or overhead cabinets a constraint.
Purewell warns that adding tap water to the upper chamber while the lower chamber is full can cause leaking. Empty or dispense from the lower chamber before refilling the top.
What are the filter replacement and maintenance needs?
Plan to replace the Purewell filter elements every 6 months for optimum performance. Purewell says each filter can provide up to 3,000 gallons, with actual lifespan depending on water quality.
A gallon estimate does not tell you the exact replacement date for your household. Follow the six-month guidance and pay attention to slower flow, since clogged or worn filters can change the time needed to fill the lower chamber.
Clean the chambers and spigot according to the system instructions. Avoid cleaning methods that could damage the filter media, and don't use a filter beyond its recommended service life.

How does the Purewell compare with other gravity filters?
The Purewell stands out for its three-media composite filter and two included elements. Culligan and Berkey offer different filter materials and claims, so compare the details that matter to your water and routine.
Purewell vs. Big Berkey
Both systems have a 2.25-gallon capacity and include two filter elements. The Big Berkey uses Black Berkey BB9-2 elements, while Purewell's composite element uses a hollow-fiber membrane, silver ion membrane and activated carbon block.
Big Berkey is shorter at 19.25 inches assembled, compared with Purewell's 20 inches. Berkey says each pair of Black Berkey elements provides up to 6,000 gallons, though actual life varies with water quality, usage and maintenance.
Purewell vs. Culligan MaxClear
Both systems hold 2.25 gallons and use gravity without electricity. The Purewell includes two filters and a stand; Culligan MaxClear includes one ceramic and carbon filter and nests under 12 inches when not in use.
Culligan says its system is certified to NSF/ANSI 42 standards to reduce microplastics, lead and Total PFAS. That named claim may help if those are your concerns, while Purewell describes a different composite media design.
What should you check before choosing the Purewell?
Choose the Purewell if its gravity-fed design, included accessories and filter schedule fit your kitchen. Before buying, decide what you need the water filter to reduce and check whether the manufacturer's claims address those needs.
Use a water report or appropriate testing to identify local concerns. A general filtration description does not prove that a system reduces a specific contaminant in your water.
Check counter and cabinet clearance, too. The system stands 20 inches tall, and the upper chamber needs to be accessible for refilling.
The Purewell is a practical match for a household that wants a non-electric countertop filter and accepts six-month element replacement. Pick the Big Berkey if its filter format and shorter height fit better, or the Culligan if its stated PFAS and microplastics claims are central to your choice; browse our large-capacity gravity filter guide for more options.
Frequently asked questions
Does the Purewell 3-Stage Gravity Filter lower TDS?
No. Purewell says the filter element does not lower TDS, so don't choose it if reducing total dissolved solids is your goal.
Its composite filter includes a hollow-fiber UF membrane, silver ion membrane and activated carbon block; those materials do not make it a TDS-reduction system.
How often should you replace Purewell filters?
Purewell recommends replacing the filter elements every 6 months for optimum performance. The brand says each carbon filter can provide up to 3,000 gallons, but actual life varies with water quality, so use the six-month guidance and watch for changes in flow.
Does the Purewell gravity filter need electricity?
No. The Purewell uses gravity to move water from its upper chamber to its lower chamber, so it needs no electricity.
It is a countertop system with a stand and spigot, and the chambers should not be refilled while the lower chamber is full.
How does Purewell compare with the Culligan MaxClear?
Both systems have a 2.25-gallon capacity and use gravity without electricity. Purewell includes two filters with a hollow-fiber membrane, silver ion membrane and activated carbon block; Culligan includes a ceramic and carbon filter and says its system is certified to reduce microplastics, lead and Total PFAS.
