Patented DNO Catalyst Technology
30 Day Risk-Free TrialReplacement HealthyAir 500™ Filter Cartridge
Our replacement filters are engineered with DNO Technology, providing the same level of protection as those that come with the machine, allowing you to continue using your product in maximum safety. On average, you will only need to replace these once every 12 months, but this will depend on the purity of the air around you.
The HealthyAir 500™ will indicate when the filter requires changing via the display on the unit.
