A Merv 8 filter is an effective way to reduce the presence of mold in your home. It is designed to trap pollen, dust, dust mites, and mold spores, making it an ideal choice for those looking to improve their indoor air quality. The filter is rated at Merv 6, 8, or 11, depending on the size of the particles it is designed to capture. Merv 5 to 8 filters are effective in controlling mold spores, hairspray, and dust.
These filters are applicable to most commercial buildings, residences, industrial workplaces, and paint booths. Merv 8 filters are 90 percent efficient on particles that are 3 to 10 microns in size. If you're concerned about the effects of inhaling fine air particles, then you may want to opt for a Merv 11 air filter instead of a Merv 8 air filter. Fine air particles measure 2.5 microns or smaller and can enter lung tissue and enter the bloodstream.
Merv 11 air filters can filter a large percentage of these particles, while Merv 8 air filters cannot. According to experts, when considering the entire indoor air quality spectrum for commercial buildings, a filter with an efficiency of Merv 13 or higher should be the product of choice. This increased efficiency will also address airborne mold spores. The Microparticle Performance Rating (MPR) is a patented air filter rating system created by 3M that measures the filtration capacity of an air filter.
The best filters are capable of removing particles smaller than 3 microns. The MERV rating system was established by ASHRAE (American Society of Heating, Refrigeration and Air Conditioning Engineers) to specify the ability of a filter to capture particles and pollutants from the air. A higher MERV rating means that less dust particles and other contaminants can pass through it. To determine the MERV rating, the performance of an air filter is determined by measuring the particle counts upstream and downstream of the filter being tested.
The minimum efficiency report value (MERV) should be indicated with the airflow velocity at which the filter was tested. Both Merv 8 air filters and Merv 11 air filters are suitable for residential use. However, a Merv 11 air filter may need to be changed more frequently than a Merv 8 air filter due to its increased efficiency. Merv 8 air filters are almost as affordable as less efficient products, making them good value for money.
