Is MERV 12 the Best Filter for Your Home?

MERV 12 filters are known for their ability to trap 80 to 89 percent of the 1.0 to 3.0 micron average particles, with an average particle size efficiency of 90 percent or better. This makes them a great choice for those looking for decent results from their air filter. According to the U. S.

Environmental Protection Agency, filters in the 7-13 range often have little difference with higher MERV ratings, but will allow your system to operate much more efficiently. With the lowest MERV rating (1-), your filter will still capture pollen, dust mites, cockroach debris, sanding dust, spray paint dust, textile fibers, and carpet fibers. Filter technology has come a long way in recent years, and MERV ratings are designed to help us determine the most effective and efficient air filter options for heating and cooling systems and more. A higher MERV rating often means lower airflow, which can make the system work harder and use more energy to do its job. In general, filters with a MERV 16 rating or lower are considered HVAC system grade filters for residential, commercial, and general hospital use. Compared to the cheaper basic filters available, medium-efficiency MERV filters such as the Nordic Pure MERV 12 can greatly reduce airborne dust, mold spores, pollen and even smoke, and doing so can help alleviate respiratory ailments according to an NIH review.

Recent innovations in air filters allow for high MERV ratings (11 to 1) with low pressure drop. This means that you can get the same level of filtration without having to worry about restricted airflow that can cause your system to operate inefficiently or even damage it. It's best to comply with oven manufacturer's recommendations or consult an HVAC professional to determine exactly which MERV rating is best for your specific system. If your home's HVAC system is not capable of handling MERV 13, opt for a filter with the next highest possible rating. Filters with higher MERV ratings should be changed more frequently (at least every three months) to avoid restricted airflow that can cause the system to operate inefficiently or even damage it. We like that they are truly MERV certified, because unlike the property ratings used by some major brands, MERV criteria are publicly available.

This means that you can be sure that you're getting a filter that is up to standard and will provide you with the best possible air quality.
