What Does Whole-House Air Filtration Cost?

From a $400 media cabinet to a $4,000 HEPA system — sized to what you’re filtering: dust, pollen, or August wildfire smoke.

The short answer

$400–$4,000

Installed on your existing ducted system. For most Puget Sound homes fighting smoke and allergies, the media cabinet + right filter is the honest first move — not the most expensive box.

Typical industry ranges for Western Washington — not a quote. Your exact price comes upfront, before any work starts, and you approve it first.

What moves the price

1

What you’re filtering

Dust and pollen are easy customers. Wildfire smoke particles are tiny — MERV 13+ or HEPA territory to actually catch them.

2

Your blower’s reality

Slamming a dense filter into a system not built for it strangles airflow. A proper media cabinet gives filtration room to breathe — that’s the honest reason for the install.

3

Filter economics

A media cabinet’s filter changes once or twice a year ($40–$100) — often cheaper per year than monthly 1-inch filters, and far better at the job.

4

Add-ons that earn it

UV lights and duct-mounted purifiers have real uses (coil growth, odors) — and plenty of oversold ones. We’ll tell you which is which for your house.

Quick answers

What actually works for wildfire smoke?

MERV 13 filtration with the fan running, a sealed-up house, and HEPA where sensitivity is high. Our wildfire smoke guide covers the playbook — the filtration cabinet is the piece that upgrades the whole house at once.

Media cabinet vs fancy purifier?

For most homes: cabinet first. It treats every cubic foot moving through your ducts. Room purifiers are a supplement for bedrooms, not a substitute.

Does a better filter strain my system?

A 1-inch MERV 13 in an old rack can. A 4–5 inch media cabinet has the surface area to filter hard without choking airflow — that’s the point of the upgrade.
