PFAS filtration for your home
Home PFAS filtration chosen from your utility's EPA PFAS results or a lab test: reverse osmosis at the kitchen sink, with PA, NJ & DE limits explained.
PFAS limits are tightening. EPA's 4.0 ppt limits for PFOA and PFOS apply to public water systems from 2029[1], Delaware's matching limits took effect in January 2026[2], and Pennsylvania's limits are 14 ppt (PFOA) and 18 ppt (PFOS)[3]. Many utilities in our area have reported PFOA or PFOS above 4.0 ppt in EPA sampling[4], and some will need to add treatment. Until then, you can treat your own water.
Our PFAS options
| WÜDR Tankless RO 800 | WÜDR Tankless RO 600 | |
|---|---|---|
| Type | Tankless RO, 10 stages, 800 GPD | Tankless RO, 8 stages, 600 GPD |
| PFAS | Reduces PFAS at the drinking tap; sized to your results | Reduces PFAS at the drinking tap; sized to your results |
NJDEP's guidance explains the point-of-entry versus point-of-use decision[5]. NSF/ANSI 53 and 58 certified drinking-water devices have been shown to reduce PFAS below 20 ppt[6].
Start with your numbers
On public water, our free report shows your utility's EPA PFAS results by compound. On a private well, PFAS needs a certified lab test; New Jersey well owners may qualify for help from the NJ Spill Fund[6]. Then we recommend the system and show the price.

Common questions
Which PFAS filter is best?
There isn't one best filter for every home. Reverse osmosis is very effective at the drinking tap; for PFAS we recommend the WÜDR Tankless RO 800, which pairs a 0.0001 μm RO membrane with 10 stages of filtration. The right choice depends on which PFAS are present and at what levels.
How often do PFAS filters need changing?
It depends on PFAS levels, other contaminants that compete for the media, and water use. We set the schedule from your numbers; for well water we recommend periodic retesting.
Clean water starts with knowing what's in it.
