PFAS Removal Cost in San Diego

A PFAS-rated under-sink reverse osmosis system, which handles drinking and cooking water, runs about $400 to $900 installed. Whole-house PFAS treatment with activated carbon or ion-exchange resin is a larger project at $3,000 to $8,000, appropriate for homes that want every tap covered or that draw from a private well. Most homeowners start with point-of-use RO because it targets the water people actually drink.

For the water you drink and cook with, a certified reverse osmosis system is the most cost-effective and reliable approach. Its membrane rejects PFAS along with dissolved solids and other trace contaminants. Whole-house treatment protects every tap but costs several times more, so it makes sense mainly when the concern extends beyond drinking water or when the home is on a well.

The EPA now requires public water systems to test for certain PFAS compounds and publish the results, so your utility report is the first place to check. If you are on a private well, or you want your own documented numbers, a certified PFAS lab test runs about $200 to $600. Filter Pros does not make claims about specific PFAS levels in your water; the lab test is what gives you real figures to act on.
