Does HEPA filter remove coronavirus?
Air purifiers with HEPA filtration efficiently capture particles the size of (and far smaller than) the virus that causes COVID-19, so the answer is yes. It falls squarely within the particle-size range that HEPA filters capture with extraordinary efficiency: 0.01 micron (10 nanometers) and above.
How does a HEPA filter work?
A HEPA filter is a type of mechanical air filter; it works by forcing air through a fine mesh that traps harmful particles such as pollen, pet dander, dust mites, and tobacco smoke. You can find HEPA filters in most air purifiers. These are small, portable units that may work for a single room.
Can you put a HEPA filter in an HVAC system?
2. Add a HEPA Filtration Unit to Your Existing HVAC System. Perhaps the most viable option for whole-space (home or work) indoor air filtration is to add an external HEPA filtration unit to your existing HVAC system. These units can be retrofitted to work with any type of ducted HVAC system.
How long do HEPA filters last?
It depends on how much you use it, but regular use based on an average cleaning schedule should keep it doing the job for between 24 to 36 months.

A washable HEPA filter should be cleaned by rinsing it under cold water. A HEPA filter marketed as “permanent” should be cleaned by gently using a vacuum cleaner to suck away dust and debris from the surface of the filter. Water should not be used on these types of filters.
How much does a HEPA filter restrict airflow?
HEPA stands for high efficiency particulate air, and this type of filtration is designed to function at a significantly higher level than a standard air filter, removing 99.97 percent of all particles in the air, down to 0.3 microns or smaller.
Will an air purifier help protect me from Covid-19 in my home?
When used properly, air purifiers can help reduce airborne contaminants including viruses in a home or confined space. However, by itself, a portable air cleaner is not enough to protect people from COVID-19.
Can air purifiers remove viruses?
That means an air purifier has to be capable of consistently drawing in enough air to reduce the amount of virus particles in the air. The faster an air purifier can cycle air through the filter, the better its chances of catching virus particles.
Can you wash and reuse HEPA filters?
If the filter is marketed as being washable or permanent, then it is possible that you can wash it or clean it off and it will still function. However, there is no standard for washable HEPA filters, and there have not been studies testing how well these filters work after they have been washed.
How do you know when to change a HEPA filter?
In general, a HEPA filter should be changed every year, pre-filters last 30 days and carbon filters can last three to six months. Clean permanent filters every three months and replace when damaged.
