Targets the wet AC coil — the surface most prone to mold/biofilm growth
Reduces microbial buildup between cleanings
Low-maintenance, pairs well with any filtration upgrade
A common add-on for mold-sensitive and CIRS-recovery homes
FAQ
Where does the UV light actually go?
Typically mounted to shine directly on the evaporator coil — the part of your system that's wet for hours after every cooling cycle, and the most common spot for mold and biofilm to establish inside the equipment itself.
Does UV replace the need for filtration?
No — UV and filtration solve different problems. UV limits growth on the coil surface; filtration captures particles moving through the airstream. Most mold-sensitive households benefit from both.
