Same Ductair DNA filters, same sizes — new online store

Filter Care Guide

How to replace your Ductair air conditioning filter in four easy steps, when to change it, and how to reorder the right size in seconds.

Why disposable beats washable

A washable filter sounds thrifty, but it holds on to dirt and bacteria over time — and every wash degrades the media a little more. A fresh disposable filter gives you consistent filtration performance and hygiene every time, keeps airflow at its best, and takes minutes to swap. That's why every Ductair DNA filter is designed to be replaced, not washed.
