Replacing filters can become costly depending how many times you change the filter. Shape and compactness of the unit depends on what type of air purifier you have.
Are HEPA filters dangerous?
Bottom line: HEPA filters shed very few fibers over their lifetime, with the highest rate of shedding when they’re new. Although some studies have linked fiberglass to cancer, a summary of research suggests that the fibers are no more harmful than other dust in the air.
What MERV rating is best for home use?
Using an air filter with a MERV rating of about 5 to 8 is appropriate for most residential homes. MERV 5 – MERV 8 filters provide good filtration and will remove most pollen, mold spores, and dust mites.
How long do HEPA filters last?

Do HEPA filters make a difference?
HEPA is good at removing larger particulate matter like pet dander, pollen and dust mites. Unfortunately, mold, VOCs, viruses, bacteria, and small particulates under 0.3 micrometers can not be removed safely from the air with an HEPA-based air purifier.
Is MERV 12 a HEPA?
HEPA stands for High Efficiency Particulate Air filters and they are super-efficient. They will range from 17-20 MERV. HEPA filters meet standards that remove at least 99.97% of airborne particles down to the size of 0.3 microns.
Is MERV 16 a HEPA filter?
To be rated as HEPA quality, filters must meet specifications set by the U.S. Department of Energy and must be capable of filtering at least 99.97 percent of particles sized 0.3 µm and larger, and Table 1 shows a considerable jump in filtration efficiency for 0.3-µm particles and larger from ≥95 percent for MERV 16 …

Is Merv or HEPA better?
High-Efficiency Particulate Air (HEPA) filters are not MERV-rated, but a HEPA filter is typically considered as MERV 17 to 20, which is the highest group in MERV ratings. True HEPA filters have at least 99.97% efficiency in trapping 0.3-micron particles.
Is a HEPA filter worth it?
“You don’t need a HEPA filter to stop dust mite, and pollen particles, as they are relatively huge. Any good vacuum cleaner should stop cat hair and dander.” … But May says that HEPA filters help contribute to a healthy home environment, even for those without allergies or asthma.
