Inova DE20 Air Purifier Filters

Looking After Your Inova DE20

Your Inova DE20 Air Purifier uses a three-stage filtration system working together to help maintain cleaner indoor air.

As your purifier captures dust, allergens, mould spores, smoke, odours and other airborne contaminants, the filters gradually become loaded and will eventually require replacement as part of normal ongoing maintenance.

Whether you’re replacing all three filters together or simply one individual filter, you’ll find the correct replacement options here.
