What does a PFAS removal system cost in El Cajon?
$400 to $950 for point-of-use RO
Point-of-use reverse osmosis is the practical PFAS answer for East County municipal homes focused on drinking water.
El Cajon runs the hottest inland temperatures in central East County, with afternoon highs routinely hitting 100 to 110 degrees from June through September. Municipal water here is among the hardest anywhere in the county, and that combination of extreme hardness and heat cycling wears out water heaters and appliances faster than almost anywhere else in the region. That accelerated damage is a big part of why treatment pays for itself sooner in El Cajon than in milder parts of the county. Chloramine and hardness both factor into the baseline system. The free in-home water test confirms your number.

Why El Cajon water costs what it does
PFAS, the class of forever chemicals the EPA set enforceable limits on in 2024, are removed most reliably at the point of use with reverse osmosis, and at the whole-house level with activated carbon or ion-exchange systems. For most San Diego homes, a PFAS-rated under-sink RO handles drinking and cooking water affordably. Whole-house PFAS treatment is a larger commitment reserved for homes that want every tap covered or that draw from a well.

How much does 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.
What is the most cost-effective way to remove PFAS?
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.
How do I know if my water has PFAS?
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.
