How to choose
Compare filtration stages and certifications
Stages describe how many filter media the water passes through, from 3 stages on the Purewell to 8 stages on the IceJoy. A certification number names the standard the filter meets: NSF/ANSI 42 appears on the Purewell, Waterdrop, IceJoy, and Culligan, while NSF/ANSI 372 appears on the Purewell and Waterdrop. Compare the numbers each product carries rather than counting stages alone, and match the certification to the reductions you want.
Match capacity and filter life
Capacity is the volume the system holds, from 2.25 gallons on the Purewell, Waterdrop, VEVOR, and Culligan to 3 gallons on the IceJoy. Filter life is the volume each filter handles before replacement, from 1,000 gallons for the Waterdrop fluoride filters and the IceJoy white filter core to 6,000 gallons for a pair of Purewell filters and a pair of VEVOR filters. Replacement every 6 months appears on the Purewell, IceJoy, and Culligan.
Check the setup before buying
Gravity systems need no electricity or plumbing, so placement comes down to counter space, a stand, and a spigot you can reach. Each system here includes a stand and a spigot. Do not add water to the upper chamber when the lower chamber is full, since adding water then can cause a leak or overflow.
