How to Clean Your Air Purifier: Step-By-Step Guide

If your air purifier has HEPA Filter, like Firefly yellow shield ,the next step for cleaning your cleaner is to clean this. This filter effectively removes allergens and dust from the air, and it can be cleaned by vacuuming or washing it with a mild detergent.

First, check if it comes with an attachment that allows you to sweep out any debris on top of the HEPA filter. If not, pick up an inexpensive broom or dustpan from your local hardware store. Next, wash off any remaining dirt using warm water and half a cup of mild detergent. To dry thoroughly, lay flat in open sunlight for several hours or place in front of a fan overnight.


      Use a clean, dry cloth to wipe off any dust or dirt from the fan blades.

      Use a soft brush to remove any dust or dirt accumulated on the filter. This can be done by gently rubbing it back and forth over the surface of the filter.

      Clean the fan blade with warm water and mild soap, then rinse thoroughly in cold water. Do not use hot water as it may damage your air purifier's motor components!

      Dry off all surfaces you have cleaned with either a dry cloth or compressed air (if you have this option).


Wipe down the body of your air purifier with a damp cloth. Next, use a dry cloth to wipe away any remaining moisture after dampening it, and then use a microfiber cloth to clean the grilles and vents. You can also use a soft-bristled brush to clean both the fan blade and your air filter(s).


You can use a damp cloth to wipe down the grilles and vents. If there are any hard-to-reach areas, try using a vacuum cleaner. Once you're done with that, give the entire unit another once-over with a dry cloth or, if possible, use compressed air to blow off any dust particles remaining in your purifier.

If your model has removable grilles and/or filters that are washable by hand, then it's recommended that you do so at least once a month (if not more often).

To clean the grilles of your air purifier:

      Use a toothbrush or cotton swab dipped in water to remove any dirt buildup on them.* If needed, apply some mild dish soap onto the bristles of these tools first before scrubbing off dirt particles.* Let dry completely before returning back into place.

Cleaning the filters on your air purifier regularly will keep them from getting clogged up with dust and debris, which can reduce their effectiveness when filtering out harmful particles in the air. This will also help keep your unit running more efficiently by reducing energy loss through heat buildup in dirty filters or blocked vents/exhaust ports.
