Indoor Air Quality in Mercer Island, WA
Filtration and ventilation for cleaner indoor air — especially during wildfire season.
Air quality on Mercer Island varies with elevation and exposure — homes closer to the water often deal with more humidity alongside wildfire smoke, which changes what filtration and ventilation setup makes sense.

Indoor Air Quality in Mercer Island: what's different here
Elevation on the island runs from about 18 feet at the lakefront to almost 400 feet near the ridge, so equipment placement, condensate drainage and access change from block to block. Older Mercer Island homes leak air, so summer wildfire smoke and outdoor allergens get inside easily. Upgrading to MERV 13 filtration and sealing ducts help the most.
Permits and inspections
Adding whole-home filtration or ventilation to existing ductwork can need a mechanical permit, depending on the scope. Mechanical and plumbing permits in Mercer Island go through the City of Mercer Island Permit Center. When the work needs a permit, we pull it, schedule the inspection and leave you the paperwork.
Utilities and rebates
Mercer Island homes get electricity from PSE, and most have PSE natural gas. Mercer Island homeowners may qualify for utility, state or federal rebates. We point you to the current programs for your address before you sign.
