How To Clean A Honeywell Air Purifier

Making sure your Honeywell air purifier is clean and in tip-top condition may be a boring job, but it is greatly important.  After all, if not maintained well, then, it basically defeats the purpose of having an air cleaner in the first place.

Purifiers that are dirty can sometimes release some of the residue stored in their filters. Additionally, particles like ozone waste, which are absorbed by the filters in the machine, could be a possible hazard at home. Therefore, it is imperative that you check up on this regularly.

Cleaning out the filters may seem complicated, but it’s actually pretty simple. But, for those of you that are new to this, here are a few tips on how to do it easily.

1. Vacuum The Exteriors

For daily maintenance of the machine, simply vacuum the outsides of the air purifier while placing special attention on the vents. Do this so that no excess dirt will be coming out of the purifier. You can also use a damp rag or towel to slowly wipe its exteriors.

2. Knowing When The Filters Need Cleaning And When To Replace Them

As a standard rule, HEPA filters need to be changed every 3 to 5 years due while a pre-filter’s life ranges from 3-6 months. However, I would suggest that you open the purifier every so often to check them yourselves. These screens need to be white (or off-white, at least). So, when you notice that they’re already a greyish color, then it's time to do some cleaning.

3. Washing the Filters

Typically, the filters of the purifier contain the most dirt. That is why it needs to be cleaned every few months so that it’s running smoothly. Once you open the case, simply take out the pre-filter and shrug off the excess waste into the trash. If you notice that there are still remnants of debris stuck on the screen, gently submerge it in warm water and scrub it lightly with your hands. After doing this, you can take it outside to hang and wait until it is completely dry before you place it back into the device.

4. Vacuum The Inside

Besides the use of soap and water, this is another method you can do that will help prolong the life of your filters. Simply detach it from the purifier, shrug off the excess dirt, and start vacuuming. You’ll notice that, while you’re doing this, the screen’s color turn from grey to white. Once it goes back to its original color, you can place it back into the machine again.

5. Replacing The Filters

There will be instances when you’ll notice that no matter how often you clean it, there seems to be something wrong with the filter. This could be a sign that it's time to replace it.

This task is very easy to do. After opening the case, locate the pre-filter and the HEPA filter, and slowly unscrew the fastener. Check also whether the secondary layer of velcro is loose or not. Once everything has been detached, pull out each of the filters and put a new one in its place. Make sure that they are placed in the right position. There should be arrows present that signify which angle the screens face.

Proceed to strap the velcro and tighten all the screws before once again closing the case. Afterwards, do a quick test. Listen carefully to the machine as it runs and, if you don’t heart any weird sounds or notice any dust coming out of the vents, then it should be working well.


Proper maintenance of your air purifier not only extends its life but it may also be of great help in making sure that it’s working optimally. Whether we enjoy doing this or not, this should be a practiced regularly. After all, we’re probably already invested a good amount of money in buying this. The least we can do is to make sure that it runs properly.
