When cleaning an air purifier filter, whether it’s a washable or permanent HEPA filter, follow these steps:
Disconnect your air purifier from the power socket and turn it off. If the air purifier is near a wall, move it to a location where you can readily access all sides.
Use a dry, soft-bristled brush to clean the filtered air outlet, usually found on the top and backside of the unit.
Remove the air purifier’s front grill. For precise details, refer to the manufacturer’s directions; however, there’s usually a pull tab for fast removal.
If your model specifies that water cleaning is safe, wash your HEPA filter with warm water and allow it to dry. If your filter is unclean, you can also soak it in hot water.
Use a vacuum to remove dust and debris from non-washable, permanent HEPA filters.
Replace the front grill if it was removed for cleaning, then replace your clean HEPA filter in the air purifier. Wipe the outside of the air purifier using a dry or slightly damp microfiber cleaning cloth.
You can now use your clean air purifier once more.
