Purifier maintenance
Published
Inspect the intake, prefilter, main filter, sensor, room placement, and maintenance record in one repeatable check.
Turn the unit off and unplug it. Follow the model's instructions for opening the housing, removing the prefilter, and accessing the main filter.
Do not assume any filter is washable. Washing a disposable HEPA-style filter can damage its media even if the frame looks sturdy.
Vacuum or wash a reusable prefilter only when the manufacturer permits it, then let washable parts dry completely before reassembly. Wipe the exterior and accessible grilles with an approved soft cloth.
Treat filter sensors and air-quality sensors as delicate components. Use the stated cleaning method rather than compressed air, liquid, or a brush chosen by guesswork.
Restore clear space around the intake and outlet and confirm the unit is sized for the room where it now lives. A purifier moved to a larger or more open area may no longer provide the intended air changes.
Log the date, hours or indicator status, unusual noise, odor, and filter condition. A maintenance record is more useful than relying on memory or color alone.
