FPR 10 is similar in strength to MERV 20, since they are both the highest rating value. However, FPR 1 doesn't necessarily equate to MERV 1. It isn't until FPR 4 and 5 that filters start trapping larger particles like household dust and lint, dust mites, pollen and pet dander.
What air filters work for Covid?
COVID-19Common questionwhat can HEPA air cleaners help to prevent COVID-19?The HEPA air cleaners were most effective when they were close to the aerosol source. These findings suggest that portable HEPA air cleaners can reduce exposure to SARS-CoV-2 aerosols in indoor environments, with greater reductions in exposure occurring when used in combination with universal masking.Jul 9, 2021
What is the highest HEPA filter rating?
HEPA H13-H14
Are higher rated air filters better?
Higher numbers indicate a better filtration of the smaller particles, like pollen and smoke, that cause many respiratory issues. And medium-efficiency MERV filters in the 8 to 13 range—the kind we would get—can remove 90 percent or more of these.
Do higher quality air filters make a difference?
A side benefit of a good furnace air filter is improved IAQ, which means your whole family breathes easier. Good air filters can stop biological contaminants, pet dander, dirt, mold spores and other pollutants. Cheap air filters can stop the largest particles only (sand and grit, hair, dust bunnies).
Do better air filters make AC work harder?
It takes special filters dedicated to air quality improvements for this job. But this raises a concern that the filters may end up making the air conditioner's job harder (and eventually the heater's job).
Do expensive air filters restrict airflow?
Does Increased MERV Decrease Air Flow? While those high MERV filters are great at filtering debris and cleaning the air in your home, they reduce the air pressure in your duct system. This could potentially raise your energy bills and take a toll on your furnace or air conditioning unit.
What is the most effective home air purifier?

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.
Are air purifiers really worth it?
An air purifier is worth it because it can remove allergens and other pollutants from the air. There are numerous health benefits associated with using air purifiers and the results vary from person to person and depend on the types of pollutants indoors. Overall, air purifiers are worth the money.
