About Ductair

South Australian air, looked after by South Australians.

Ductair has been part of the South Australian air-conditioning trade for over 40 years — a family-run business supplying ducting and air-distribution products that installers actually rely on. Our DNA return-air filters carry that same standard into your home.

Why we make the DNA filter

A ducted air-conditioning system is only as clean as the air it pulls in. A blocked or dirty return-air filter makes your system work harder, drives up running costs and pushes dust, pollen and allergens back through every room. A fresh filter fixes all of that — quietly, and for less than a dollar a day.

Built for a simple job, done properly

Every DNA filter is made to drop straight into a Ductair quick-change return-air grille. No tools, no tradie, no guesswork — match the number on the red sticker, order, and swap it in a few minutes. That's the whole idea: keep your air clean without making it complicated.

Questions about your system or the right filter for it? Our team is here Monday to Friday. Call 1800 DUCTAIR (1800 382 824) or email sales@ductair.com.au.
