Air purification for Northwest Oregon homes.
High-MERV filters, UV-C systems, electronic air cleaners, and HRVs for allergies, wildfire smoke, and pollutants regular filters miss.

Air purification options
Whole-home air purification options — four solutions matched to the problem.
No one solution fixes everything. We assess your home and recommend the smallest system that actually solves the problem — not the biggest box we can sell.
High-MERV media filters
A 4–5" deep MERV 13–16 cabinet replaces the 1" filter at the return. Captures particles down to 0.3 microns: pet dander, pollen, smoke. Service every 6–12 months.
UV-C light systems
Mounted at the indoor coil, UV-C kills mold spores and bacteria as they pass through. Especially valuable in damp Pacific Northwest basements and crawlspaces.
Whole-home electronic air cleaners
Active polarized-media or ion-based cleaners that capture ultra-fine particles and odors traditional filters miss. Higher capture rate, lower pressure drop.
HRV / fresh-air systems
Heat-recovery ventilators bring filtered fresh air in while exhausting stale air — without losing heat. Critical for tight, energy-efficient homes.
Why air purification matters
Indoor air problems homes across the metro deal with — and what filtration solves.
Wildfire smoke
Pacific Northwest summers increasingly mean smoke from regional fires. A high-MERV filter or active electronic cleaner makes the difference between hiding indoors and breathing clean air.
Allergies & asthma
Pollen, pet dander, dust mites, and mold spores all show up at returns. The right purification step can dramatically reduce trigger load.
Older homes, leaky ducts
A lot of housing stock across the metro is 40+ years old. Leaky returns pull dust from attics and crawlspaces straight into the air handler. Filtration helps; sealing helps more.

Air purification questions, answered.
- It depends on what you're trying to solve. Allergies usually want a high-MERV media filter. Mold or basement issues want UV-C. Tight new construction wants an HRV. We do an in-home assessment first — no point selling you a system that doesn't match the problem.
- High-MERV media filter cabinet: $400–$1,200 installed. UV-C system: $500–$1,200. Electronic air cleaner: $1,200–$2,800. HRV: $2,500–$5,500+. We give a real number after we see your system.
- It can — if you stick a MERV 13 1" filter into a system designed for MERV 8. The pressure drop strains the blower. The right answer is a deep-pleat 4–5" filter cabinet, which gives you high MERV without the airflow penalty. We size it correctly.
- If filtration has been good and the ducts are sealed, no — you can go years without cleaning. If filtration was poor before (cheap throwaway filters), or if you've had pets, smokers, or major dust events, a one-time duct clean before installing the new system makes sense.
- Limited — most rebates are for the HVAC equipment itself, not filtration. HRVs occasionally qualify under whole-home energy programs. We'll flag any incentives you're eligible for at the estimate.
- Standard 4–5" deep-pleat filters typically run 6–12 months between changes, depending on home conditions. We can include filter swaps in a Comfort Care maintenance plan — one less thing to remember.
