An air purifier is just like your air conditioning, it needs to maintain over a period of time.
The good thing about this is that you don’t need to call a professional to do it.
Cleaning and maintaining the air purifier can be done completely by yourself.
How to clean an air purifier
#1. Turn off the device.
Just like any other electronic device, the first thing you do before cleaning or maintaining it is to turn off the device and disconnect the device from the power socket.
#2. Break open the air purifier
As the nature of every air purifier requires to change its filter, it is usually relatively easy to break open an air purifier.
#3. Dismantle the components
Usually, you will be able to see the filter of the air purifier as soon as you break open it.
Air purifier today comes with several layers of the filter.
You should be able to dismantle the filters from here.
In the event, if you can’t dismantle into smaller pieces, you can skip this step and move on.
I personally owned one air purifier that can’t dismantle the filter any further.
#4. Start with cleaning the pre-filter
Typically, your air purifier should have a pre-filter to filter large particles such as dust, hair, pet dander, and etc.
That is like the dirtiest part of your air purifier and possibly the only parts that you can really clean to make a difference.
A brush should do the job usually if you clean your air purifier every 30 days.
However, if you had not been cleaning your air purifier for a very long time, it might be difficult to clean with a brush and you will have to wash the pre-filter instead.
Note that if your pre-filter is not possible to dismantle out from the HEPA filter, please DO NOT WASH it. I will tell you why when you reach the section of the HEPA filter.
#5. Next, the HEPA filter
Unfortunately, there’s no home cleaning required for your HEPA filter.
You might think that you could vacuum the filter or even wash it but don’t bother doing it.
Vacuuming the HEPA filter does not give you any greater benefits.
As for washing the HEPA filter, it can only potentially damage the filter and reduce the effectiveness of it.
Thanks to Smart Air Filters, they had done the research to conclude that the HEPA filter is not recommended to clean or wash.
Therefore, the only thing you can do is to replace the HEPA filter.
Generally, it is recommended to replace the HEPA filter every year although, for some extreme cases, a HEPA filter may be required to change every 6 months.
If you are using the high-end PECO type of air purifier from Molekule, you have to change the PECO filter as often as the HEPA filter.
#6. Replace the activated carbon as well
Usually, when you buy the filter replacement for your HEPA filter, it comes with the activated carbon package as well.
The activated carbon is not cleanable too as its function is to absorb odor or VOC.
Therefore, you shouldn’t find anything to clean for this part of the filter.
#7. Clean the inside of the air purifier
Since you had breakopen your air purifier, take this opportunity to clean the inside of your air purifier.
For this, it is safe to use a damp cloth to wipe the inside of the air purifier.
#8. Assemble back all the filters and parts
Once you are done with all the cleaning, it is time to put all the pieces back together.
#9. Turn on your air purifier
After piecing everything, connect your air purifier to the power socket and turn it on.
If your air purifier is smart enough to warn you that you may have misassembled your parts, there should be some kind of beeping warning.
If not, you can try to pay attention to the level of noise whether does the air purifier makes a louder noise than before.
Generally, if none of the above happened, your air purifier is good to go again.
