Indoor air quality for smoke season and the nine damp months
Indoor air quality in Portland means two very different battles: August wildfire smoke that turns the sky orange, and the November-through-May damp that feeds mold in closed-up houses. The right filtration and ventilation setup wins both.

The Portland air playbook
Smoke-season filtration
MERV-13+ media filters or electronic cleaners integrated with your heat pump — so AQI-200 days outside stay AQI-20 inside. Filters delivered before fire season, not during it.
HRV / ERV fresh air
Tight modern homes and remodels need mechanical fresh air. Heat-recovery ventilators bring it in without throwing your heating out the window.
Moisture & mold control
Nine months of damp finds every cold corner. Ventilation balancing, dehumidification, and crawlspace-adjacent advice from people who've seen under Portland houses.
Radon-aware ductwork
Parts of the metro sit on radon-prone soil (placeholder note — test data per address); we coordinate testing and mitigation-friendly duct design.
Air quality upgrades bolt cleanly onto a heat pump install or run standalone with your existing system — even ductless setups have filtration options. Care Plan members get smoke-season filters shipped automatically each July — see the Evergreen Care Plan.
