UV-C vs. Filters
Filters catch particles by size. UV-C light kills biologicals that may pass right through a filter. The two work best together. UV handles mold and germs; a good filter handles dust and smoke.

What a UV Air Purifier Does in Your Sacramento Home
A UV air purifier is not a filter. It uses UV-C light at 254 nm to break down the DNA of mold spores, bacteria, and viruses. It mounts inside your air handler or return duct. Every time air passes through, the light hits it. Studies show 99 percent or more of airborne biologicals are wiped out with proper dose and exposure. Fresh Air installs whole-home UV units tied to your existing HVAC unit.
Coil Protection
Mold and biofilm grow on wet AC coils in the dark. A UV lamp aimed at the coil keeps it clean. A dirty coil cuts cooling output and raises your energy bill.
Sacramento Mold Season
Sacramento fall fog and delta moisture raise indoor humidity. Mold spores enter through open doors and windows. A UV unit in your ductwork hits spores before they can land and grow.

UV Air Purifiers and Your Sacramento HVAC Unit
Air in a typical home recycles 40 to 75 times a day through the HVAC unit. Each pass through the UV lamp adds up. The key is dose, which is UV strength times exposure time. A well-placed lamp at the right wattage gives a big enough dose to inactivate mold and bacteria. Fresh Air sizes the lamp for your air handler and duct speed.

UV Air Purifier Hvac Sacramento FAQ
Does a UV purifier replace my air filter?
No. A UV unit kills biologicals but does not stop dust or smoke. Keep your filter in place. MERV-13 plus a UV lamp gives you the best of both approaches.
How long do UV lamps last?
Most UV lamps need to be swapped once a year. The bulb may still glow after 12 months but its germ-killing power drops off. Fresh Air checks the lamp at your annual tune-up.
Will a UV purifier help with Sacramento wildfire smoke?
UV light does not trap smoke particles. A MERV-13 or higher filter is the right tool for smoke. A UV unit adds protection against mold and germs that a filter does not address.
