What is Merv 8 Rating and How Does it Compare to Other Filters?

When it comes to air filtration, the Minimum Efficiency Report Value (MERV) rating is an important factor to consider. MERV ratings measure the effectiveness of a filter in capturing particles between 0.3 and 10 microns in size. A Merv 8 filter is considered a superior filtration compared to air filters with a lower MERV rating, as it captures 90% of particles that are 3 to 10 microns in size. This is usually good enough to do the work of an average household, such as controlling mold spores, hairspray and dust. But is filtration enough? In many cases, a MERV 8 air filter is more than adequate.

However, if you are concerned about outdoor air pollution, family members with respiratory problems, or pets in the house, then a higher merv rating might be a good idea. A MERV 8 air filter is common in homes, commercial buildings, paint booths, and industrial workplaces. MERV 8 filters will collect particles as small as three microns, perfectly suited for any residential application. They are almost as affordable as less efficient products, making them good value for money. However, for particles common in home air, such as pet dander and mold spores, a Merv 13 air filter is an excellent choice for many homeowners. If you're trying to choose between a MERV 8 air filter and a MERV 11 air filter, here's what you need to know.

According to the National Air Filtration Association, there are 16 MERV values, from 1 to 16, and the efficiency of the tested filter increases as the number of MERVs increases. The MERV 13 air filters even provide additional filtration power against fine particles compared to the MERV 11 filters. When selecting an air filter for your home or workplace, it's important to consider the MERV rating. A higher rating means better filtration and improved air quality. However, using an air cleaner with a MERV rating that is too high can damage the compressor, heat exchanger, and air conditioner coil.

If you're wondering what MERV rating your unit can handle, there are often a few simple steps you need to follow. MERV ratings allow you to make comparisons between filters to determine which is most efficient for your specific application to eliminate annoying contaminants in a home or workplace. If you're worried about the effects of inhaling fine air particles, that's another reason to choose a MERV 11 air filter instead of a MERV 8 air filter. All air filters require regular cleaning and filter replacement to function properly. Follow the manufacturer's recommendations for maintenance and replacement.
