Right-sized advice
If one tap is the only problem, a whole-house system is overkill. We tell you that up front and quote what fits.

Under-Sink Drinking Water Filters in San Mateo
Compact, tankless filtration that fits in the cabinet and serves the kitchen tap. We install under-sink filters in San Mateo homes and condos near Third Avenue and all over town.
A Simple Fix for Kitchen Water
Not every house needs a whole-house system or an RO unit. San Mateo Water Filtration fits under-sink drinking water filters in San Mateo for people who mainly care about what comes out of the kitchen tap. A good one cuts chloramine taste and odor and, with the right cartridge, reduces lead from older solder.
It suits condos near downtown, rentals, and houses built before 1986 where lead is a fair question. The visit is short: we take a reading, fit the filter and faucet, and check for leaks.
What Goes Into an Under-Sink Install
Small system, but the details still matter. Here is the work.
-
Tap reading
We measure chloramine and TDS at the kitchen faucet. If lead is a concern, we also explain how to send a sample to a lab for a proper lead result.
-
Cartridge choice
We match the cartridge to the issue: a carbon block for taste and chloramine, or a lead-rated block for older plumbing. You get the cartridge the reading points to, not the priciest one on the shelf.
-
Cold-line connection
An angle-stop adapter tees off the cold supply under the sink. Your main faucet keeps working exactly as before.
-
Housing mount
The filter housing is mounted to the cabinet wall at a height that makes changes easy. We leave clearance so the cartridge comes out without a fight.
-
Dedicated faucet or inline setup
Most installs get a small drinking faucet on the sink deck. Some setups run filtered water through the main faucet instead, depending on the fixture.
-
Faucet placement and finish
The drinking faucet comes in finishes that sit well beside your main fixture. We set it where it is easy to reach without crowding the sink or the soap dispenser.
-
Flush and leak check
New carbon releases fine particles, so we flush it before you drink. Every fitting is checked dry before we close up.
-
Fridge connection
If the fridge has a water line nearby, filtered water can feed the ice maker too. We plan that during the same visit.
-
Change reminder
You get the cartridge part number and the change interval in writing. Swaps take a couple of minutes and need no tools.
How the Visit Goes
-
Reading
We take a reading at the kitchen tap and look at the plumbing under the sink. You hear which cartridge fits your water and why. A written quote follows on the spot. The whole thing takes a few minutes.
-
Fit
We tee into the cold line, mount the housing, and set the faucet. The cabinet stays usable, with the filter tucked to one side. Most installs take about an hour.
-
Flush and check
We flush the new cartridge, then run water through the faucet and check every joint. You taste the difference before we pack up. We show you how the cartridge twists out for future changes.
