What is a HEPA filter and how does it work?
HEPA filters or High-Efficiency Particulate Air filters have been designed to trap particulate matter from the air that is as fine as 0.3 microns to purify the air that we breathe from allergens, dust, dirt and pet hair. The demand and popularity of HEPA filter-based vacuum cleaners are increasing globally as they have been proven effective at different contaminants from indoor air and thus helping people suffering from respiratory hazards such as dust allergy, asthma, or other respiratory health conditions.
To efficiently remove pollutants from the air, HEPA filters comprise a dense mesh of microfibers that are designed to serve as an obstacle to capturing the particulate matter and ensuring that they do not get released back into the air.
Why do we need to clean HEPA filters?
When you are using HEPA filters for a considerable time, large amounts of dirt, dust, debris, and pet hair get trapped within the dense mesh of HEPA filters reducing their effectiveness in purifying the indoor air of living rooms and commercial spaces. Regular maintenance of HEPA filters is essential to ensure maximum productivity in trapping the particulate matter from indoor air so the users do not fall sick by inhaling polluted air.
Can you wash a HEPA filter?
Most of the HEPA filters are not washable as water will reduce the productivity of the filter and even the delicate mesh of microfibers can break when they encounter water. So, if you have decided to wash the HEPA filter, please consider carefully going through the manufacturer’s instructions to know whether the HEPA filter is tolerant to water. If you want to abide by the safe route, consider cleaning the HEPA filter every 4-6 months so that it gets clogged neither its productivity gets reduced and your respiratory health is not compromised.
When you notice visible damage or holes in the HEPA filter do not forget to replace it and get a new one installed in your vacuum cleaner to breathe in pure and germ-free indoor air. It is recommended not to wash the HEPA filter unless it is labeled as washable since it might end up losing its electrostatic charge and fail to trap the airborne particles.
Materials needed to clean the HEPA filter with compressed air
When you are cleaning a HEPA filter with compressed air, you need to keep a list of things handy to complete the cleaning process without experiencing any hazards. Primarily you will need a canister of compressed air made for cleaning purposes of electronic equipment so that additional pollutants do not get inserted into the HEPA filter in this process. Secondly, it will be convenient if you can arrange a vacuum cleaner with a soft rotating brush so that you can conveniently brush away the loose dirt and dust trapped in the fine mesh of the HEPA filter.
Thirdly a soft-bristled brush will come to your help in the cleaning process of the HEPA filter to shed off any larger particles from the external surface of the HEPA filter. Lastly for your safety depending on the level of dirt and dust accumulated on the HEPA filter consider wearing a mask on your face and gloves on your hand so that you do not end up inhaling the dust and pet hairs trapped in the filter and develop respiratory irritations.
How to clean a HEPA filter with compressed air? STEP-BY-STEP Guide
When starting the process of cleaning a HEPA filter with compressed air, turn off the vacuum cleaner and remove the cord from the power socket after carefully going through the manufacturer’s instructions, remove the HEPA filter carefully so that it does not get damaged in any way and keep in mind to not exert additional pressure to remove it. Secondly, carefully examine the HEPA filter externally to get an idea of the degree of dust and dirt accumulated on it or if any part of the filter is damaged.
In the next step, use the soft-bristled brush to shed away all the loose dirt and dust from the HEPA filter without exerting pressure else the mesh of microfibers will break. You should from one corner and with gentle strokes shed away all the loose debris from the entire surface of the HEPA filter. Fourthly take the compressed air canister position its nozzle at least a few inches away from the HEPA filter and blow short bursts of air so that the extra dirt and debris stuck in the fine mesh of the filter gets removed easily.
Again, remember not to blow heavy streams of air to prevent your HEPA filter from getting broken or damaged. Now take the vacuum cleaner with the soft rotating brush and fix a low setting to use it to remove any additional dust if left out during the previous processes to ensure a comprehensive cleaning session of the HEPA filter. If you feel that your HEPA filter is heavily dirty with sticky debris then you can repeat cleaning with the soft-bristled brush and the compressed air canister once more to remove the blackish appearance.
After you have completed all these steps, again examine the cleaned HEPA filter to notice any signs of hole or damage since in that case instead of replacing it you will need to replace the HEPA filter. Lastly, if you do not notice any signs of visible damage and the HEPA filter becomes visibly clean then following the manufacturer’s guidelines again you should reinstall the HEPA filter inside the vacuum cleaner.
Safety Measures to clean a HEPA filter with compressed air
When deciding to clean a HEPA filter with compressed air, be sure to carry the entire cleaning process in a well-ventilated area to avoid inhaling the cleaned dust and debris and ending up developing respiratory irritation. You should thoroughly examine the cleaned HEPA filter to notice any signs of holes or damage since in that case instead of replacing it in the vacuum cleaner you will need to replace the HEPA filter to avoid developing respiratory issues.
Remember not to blow heavy streams of air or exert pressure to prevent the intricate mesh of microfibers of the HEPA filter from getting broken or damaged. Always consider following the manufacturer’s guidelines multiple times to uninstall and reinstall the HEPA filter inside the vacuum cleaner to prevent any damage and ensure a successful cleaning process.
Conclusion
Yes, you can clean the HEPA filter with compressed air but consider following the manufacturer’s guidelines and adopting a few precautions like not exerting pressure, cleaning in a well-ventilated area, and replacing the HEPA filter upon noticing visible signs of damage. Again, when using the compressed air canister, hold it a few inches away from the dirty HEPA filter and remember not to blow heavy streams of air to prevent your HEPA filter from getting broken or damaged.
FAQs
Can you clean a HEPA filter and reuse it?
Yes, you can clean a HEPA filter and reuse it if there are no visible signs of damage like to say, for example, holes, breakages, or extremely blackish carbon deposits. In that case, to ensure a healthy atmosphere you should replace the HEPA filter of your vacuum cleaner.
Is a HEPA filter ruined if it gets wet?
There are chances that a HEPA filter will get ruined if it encounters water as it might end up losing its electrostatic charge and fail to trap the airborne particles.
