What is a HEPA Filter & How Does it Function?
HEPA (High-Efficiency Particulate Air) filters are highly effective at improving indoor air quality by trapping 99.97% of contaminants and allergens as small as 0.3 microns.
Originally developed during World War II for gas masks, HEPA technology is now widely used in residential vacuum cleaners and air purifiers. These filters consist of multiple layers designed to capture particles through different mechanisms.
Larger particles are sieved out in the outer layer, while smaller particles are trapped in the inner layer made of glass fiber material. HEPA filters are recommended for individuals with allergies and respiratory issues due to their superior filtration capabilities.
However, they do not eliminate all airborne particles, such as some viruses, and cannot prevent allergens from entering the home through open windows and doors.
Despite this limitation, HEPA filters remain an essential tool for improving indoor air quality and promoting respiratory health.
How Do You Clean A HEPA Vacuum Filter: A Step by Step Process
HEPA filters have become part of everyday life, but when a HEPA filter is dirty and clogged, it begins to lose its effectiveness.
At this point, if the filter is not tagged as washable or permanent, it is to be disposed of.
However, if it is washable or permanent, the following procedures should be used to clean it:
Cleaning a washable HEPA filter
Step 1: Consult the instruction manual to find out if your HEPA filter is washable and how to go about it. Some are periodically washable as water may affect their functionality.
If there is no instruction manual, visit the manufacturer’s website and enter the model number to access a downloadable copy.
Step 2: Disassemble your device to gain access to the filter and clean it thoroughly. Take the filter out of your home since filters tend to carry more dust and dirt if they are larger.
Step 3: Remove the filters, but first turn your device off and unplug it from the power source. Then remove the instrumental panel protecting the filter and then gradually slide out the HEPA filter. Refer to the manual for guidance.
Step 4: Loosen the dust from the filter by gently tapping it over the dustbin. The filter may be clogged by dirt and dust based on the cleaning frequency of your device. The tapping loosens the dirt and removes the gathered dirt.
Step 5: rinse the HEPA filter with water at medium pressure. If it is a small filter, you can clean it under tap water in your kitchen or bathroom. If it is a large one, rinse it in the garden with the garden hose.
Consult your manual to see the manufacturer’s recommendations, such as the use of cold or lukewarm water. Therefore, ensure that the water temperature is right before rinsing the filter.
Step 6: leave the filter to dry for at least 24 hours. Shake any excess water so that drying can be easy because the filter should be installed back in the vacuum cleaner when it is completely dry.
Cleaning a Permanent HEPA Filter
If you have a permanent HEPA filter, then these are the cleaning steps to follow:
Step 1: Remove the filter and since it has a lot of dirt and dust, take the appliance outside to avoid indoor air pollution. Just remember to turn off your device and unplug it.
You can refer to the handbook if you do not know how to remove the filter.
Step 2: There are other filters attached to a permanent HEPA filter which also need to be cleaned with water for two or three minutes, or until the water runs clear.
The ultra-fine filters can be tenderly cleaned with a damp sponge or a brush with soft bristles.
After that, dry the filters with a towel and leave them to dry naturally for 24 hours.
Step 3: use a handheld vacuum with powerful suction to clean the HEPA filter to remove debris and dirt from it. Use a nozzle attachment or a soft brush to prevent any damage to the filter.
Vacuum the filter until every speck of dirt has gone.
Step 4: After both the pre-filter and HEPA filters have been cleaned and dried, reassemble your device. First, position the HEPA filter and then the pre-filters. If you are not sure how to go about it, refer to the instructions in the handbook.
FAQs
How do I know if my HEPA filter is dirty?
If you want to know if your HEPA filter is dirty, there are two ways of checking. One way is with the help of a filter indicator, which shows you when your filter has lost its capacity to function efficiently due to dirt and clogging.
The other method is by manually checking the filter. If you see any buildup of dust, dirt, or debris in the filter, then it is time to clean it. However, if the filter is entirely clogged up, it should be replaced instead of being cleaned.
Are there different types of HEPA filters for vacuum cleaners?
True HEPA filters capture 99.97% of particles as small as 0.3 microns, meeting strict U.S. standards. Higher grades like H12 to H14 provide even better efficiency. However, HEPA-type filters, often less effective, capture only 85%-90%. Military-grade options (A-E) cater to specialized needs.
What Is the Difference between HEPA-type filter and True HEPA?
True HEPA filters, rated MERV 17-20, capture 99.97% of particles as small as 0.3 microns, with serial numbers and test results printed on them. HEPA-type filters, with a lower MERV rating of 13-16, capture 90-99% of particles, mainly larger than 2 microns, offering less filtration density.
The Wind-Up
Keeping your HEPA vacuum filter clean ensures your vacuum performs at its best. Follow these simple steps regularly to maintain efficiency and prolong its life. A clean filter not only helps your vacuum run smoothly but also keeps your home free from dust and allergens.
