Do you really need a HEPA filter?
“You don’t need a HEPA filter to stop dust mite, and pollen particles, as they are relatively huge. … A HEPA filter traps most bacteria, pathogens, microbial spores, tracked-in soil particles, combustion soot particles, some construction dust, and some virus particles (that are stuck on larger particles).
What are the two disadvantages of HEPA filters?
The two cons associated with HEPA filtration include the following: Small Pollutants Can Escape Filter: Although HEPA filters capture and remove particulates larger than 0.3 microns, there is a potential for smaller particles to pass through the filter that can be hazardous when present in your air.
Does a HEPA filter block Covid?
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.
Can HEPA filters make you sick?

How much does a HEPA filter cost?

What makes a filter HEPA?
HEPA stands for high-efficiency particulate air. 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.
Can you breathe through a HEPA filter?
Paper products that you can breathe through, such as coffee filters, paper towels, and toilet paper. HEPA filters with multiple layers block small particles almost as well as N95 respirators, studies show. But they might have tiny fibers that can get into your lungs.
Why are HEPA filters rarely used in homes?
Volatile organic compounds (VOCs): Common household items such as aerosol hair spray, upholstery cleaner, ammonia, and many others contain VOCs—toxic substances that can irritate eyes and respiratory passages, and even lead to cancer. The gasses from VOCs are smaller than 0.3 microns, so a HEPA filter won’t stop them.
