Air Filter Replacement Done Right

A filter that's been in place for six months is essentially a brick. It restricts airflow, forces the blower motor to work harder, freezes the evaporator coil in summer, and allows dust to bypass the housing and circulate freely. Yet a huge percentage of South Bay homes go a year or more between changes — usually because no one knows where the filter is, what size to buy, or how to access it.

AirCare Solutions handles filter replacement on every duct-cleaning visit at no charge, and we offer standalone filter service for homeowners who'd rather not deal with it themselves. We carry the most common sizes on every truck — 16x20x1, 16x25x1, 20x20x1, 20x25x1, 14x25x1 — and can source any non-standard size with a few hours' notice.

We also consult on MERV upgrades. Most South Bay homes are running stock fiberglass MERV-4 filters that catch almost nothing. Upgrading to a MERV-8 pleated filter dramatically improves air quality without straining the system; MERV-11 is appropriate for households with allergies or pets; MERV-13 captures most viral-sized particles but requires a system rated for the higher resistance. We'll measure your equipment and recommend what's safe.

For homes that want the very best filtration, we install whole-house media cabinets and dedicated HEPA bypass units. These provide hospital-grade air filtration without restricting the main system. Free in-home consultation available.
