Do HEPA Filters Work Better Dirty?

This pre-filter will capture some of the dust and larger particles, and some of these pre-filters are washable to allow you to remove any dust and dirt they accumulate. However, experts agree that HEPA filters should always be replaced when they are dirty, not cleaned. While a HEPA filter is a good option for keeping the air clean, you should make sure you keep up with the cleanliness of other areas of your home. If you can combine regular cleaning with a HEPA filter, your home will be safer for you and your family. It's important to understand the difference between HEPA and true HEPA filters.

A HEPA filter in your vacuum cleaner can usually be washed or vacuumed. On the other hand, air purifiers use true HEPA filters which should be replaced when dirty. Carbon filters should only be placed in the sun for 3 hours and are suitable for reuse. Cleaning a HEPA filter is not an easy job. You have to take the filter out to the outside to clean it properly, otherwise it will litter the indoor area with dirt and dust.

To keep your home or business free of contaminants, the HEPA filter plays a crucial role. You should also clean the filter outside your home, otherwise contaminants could return to the air and could include other microbial growths that have occurred on the filter. You may also be able to inhale some of the contaminants in the filter. A normal HEPA filter will have around 2500 layers of intertwined glass threads that allow microscopic particles such as mold, pollen, PM2.5, viruses and bacteria to be captured. Therefore, avoid washing when possible, as you may need to change filters sooner than expected due to airflow restriction, which requires higher levels of energy consumption than normal.

You should also allow the HEPA filter to air dry for at least 24 hours before placing it back in the air cleaner. Most permanent HEPA filters can be gently cleaned with a vacuum, while a washable HEPA filter can be cleaned by rinsing it in cold water. There are many materials used to make HEPA filters, such as thick glass fibers, coated animal hair, vegetable fibers, synthetic fibers, synthetic foams, metal wool or metals, and expanded sheets. That's why cleaning the HEPA air filter regularly is a good choice. In addition to HEPA filters, there are several air purification technologies available that you can use to improve the air quality in your home. You can tell if the HEPA filter is dirty when an air purifier struggles to capture air pollutants in the air. As mentioned above, cleaning the HEPA filter could damage the fibers that help the filters stop unwanted debris and small particles.

Anything smaller than 0.3 microns, such as smoke and airborne chemicals, can still pass through the filter. In such cases, you can easily wash or clean these filters without damaging them and they will continue to work. If the filter label does not contain a term such as “Washable” or “Permanent”, never attempt to clean it. That's why it's important to have the correct HEPA filters in your home before installing them. If this custom air filter doesn't work properly, you can easily replace it.
