⚠️ Caution: Always disconnect power to the unit before servicing
Maintaining your Ultrafine 468 filters properly should only take you ten minutes and is crucial to keep your unit functioning properly. The level of maintenance required for your unit’s filters is based on the pollution level in your environment. Filters need to be replaced and cleaned more often if your unit is being used in a heavily polluted environment.
Your Ultrafine 468 main filter should be replaced every 9 to 12 months, and both the pre-filter and post-filter should be replaced every 6 months.
The Ultrafine 468 high-energy grid should be cleaned every 3 months with a lint-free cloth and the pre-filter should be cleaned every 3 months using a vacuum wand to remove any particle build-up.
