How to Winterize Your Air Cleaner


Step 1

The cleaning process will produce plenty of dust and debris. Turn off the air cleaner, unplug it and move it into a room with a floor that can be easily cleaned, or move the unit outside.

Step 2

Remove the center HEPA filter and carbon prefilter that is wrapped around the HEPA filter.

Step 3

Clean the plastic housing vents with a brush. Vacuum loose dust with a brush attachment and use a soft cloth to wipe away any remaining dirt from the housing.

Step 4

Wipe the inside of the lid thoroughly and check the lid seal to make sure no dust or dirt will keep it from forming a tight seal with the air cleaner housing.

Step 5

Clean the HEPA filter with a vacuum cleaner.

Step 6

Replace your carbon prefilter, a vital part of the HEPA filter that collects dust particles, hair and dirt. Cut the carbon filter to size and fasten it to the HEPA filter. Discard the old carbon filter.

Step 7

Place the HEPA filter and prefilter back into the plastic housing. Replace the lid, turn it clockwise and secure it tightly.

Step 8

Turn the air cleaner on and test to ensure that everything works.
