Catalytic where it counts
Plenty of carbon filters sold online are rated for chlorine, not chloramine. We fit catalytic media for Peninsula water so the filter does the job you paid for.

Carbon Filtration Systems in San Mateo
Carbon media matched to chloramine, the disinfectant in most San Mateo tap water. We fit carbon systems for houses along Crystal Springs Road and right across the city.
Why Carbon Matters on the Peninsula
Chloramine is the reason. San Mateo Water Filtration fits carbon filtration systems in San Mateo because the regional supply is disinfected with chloramine, a chlorine and ammonia blend that lasts in pipes and slips past basic pitcher filters. Catalytic carbon is built to break it down.
Most people reach out when the tap water tastes or smells like a pool, or when they want better water for coffee, tea, and cooking. The visit covers a chloramine reading, a recommendation on where the carbon goes, and the install.
Carbon Install Checklist
Carbon is simple chemistry, but the details decide whether it works on chloramine.
-
Chloramine reading
We measure total chlorine at the tap, which tells us how much chloramine the carbon has to handle. That figure sets the media type and amount.
-
Media selection
Standard activated carbon is fine for chlorine and general taste. For chloramine, we use catalytic carbon, which has a treated surface that breaks it down much faster.
-
Contact time sizing
Carbon needs time in contact with water to work. We size the tank or block so flow is slow enough for real reduction.
-
Point-of-entry tank
For the whole house, a carbon tank on the main line treats showers, laundry, and every tap. It suits people who notice the smell in the bathroom as much as the kitchen.
-
Point-of-use block
For drinking water only, a carbon block under the sink is smaller and cheaper. It is often all a kitchen needs.
-
Sediment protection
A pre-filter keeps rust and grit from clogging the carbon bed. This matters in houses around Sugarloaf and Laurelwood with mixed plumbing.
-
Upflow or backwash valve
Larger tanks use a valve that keeps the media bed loose and evenly used. That keeps taste steady from the first gallon to the last.
-
Flush-in
New carbon releases fine dust. We flush it out until the water runs clean before anyone drinks it.
-
Replacement plan
You get a written note of when the cartridge or the media is due. Carbon wears out quietly, so the schedule matters more than taste.
Fitting Carbon, Step by Step
-
Measure
We take a total chlorine reading at the kitchen tap and a shower. We ask what bothers you most: taste, smell, or dry skin. Based on that, we recommend a point-of-use block, a whole-house tank, or both. Plan on fifteen to thirty minutes.
-
Install
Point-of-use blocks go in under the sink, usually in about an hour. A whole-house tank goes on the main line with a bypass, which takes a few hours. Either way, the work is done in one visit.
-
Confirm
We take a second total chlorine reading after the flush. You see the chloramine figure fall sharply on the meter. We hand over the replacement schedule and the part numbers.
Why Choose San Mateo Water Filtration for Carbon Filtration Systems
Sized by reading, not guesswork
Contact time and media volume are set from your measured residual and flow. That is the difference between a filter that works and one that just sits there.
Straight talk on scope
If a kitchen block solves it, we will not push a whole-house tank. If the smell is in every shower, we will tell you that too.
