Are Merv 11 Filters the Best Choice for Allergy Sufferers?

Are you an allergy sufferer looking for the best air filter to reduce your symptoms? If so, you may have heard of MERV 11 filters. But what are they and are they really the best choice for allergy sufferers?MERV stands for Minimum Efficiency Reporting Value. It is a rating system developed by the American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE) to measure the effectiveness of air filters. A MERV 11 filter is rated at MPR 1000, meaning it is capable of capturing most fine particles, including pollen and pet dander.

MERV ratings 9 to 11 indicate at least 90% particle resistance. For those with extreme allergies, a MERV rating of nine or higher is recommended. These filters can capture particles as small as one micron. While MERV 11 filters may be more expensive than standard filters, they are worth the extra cost due to their increased efficiency.

In addition, if someone has an allergy or respiratory problem, a MERV 11 or even a MERV 13 filter should be used. The same applies to homes with smokers or pets, as MERV 11 filters are better at eliminating odors.

MERV 11 Filters: What Do They Filter?

MERV 11 filters are effective in controlling dust, pollen, dust mites and pet dander. They are applicable to most commercial buildings, residences, industrial workplaces and paint booths.

In addition, they are ideal for anyone with allergies as they filter more contaminants than the MERV 8 filter. Pleated filters work harder than fiberglass filters and don't need to be changed as often; they can last up to three to five months before needing to be replaced. HEPA (High Efficiency Particulate Air) filters are made of densely packed layers of glass fibers instead of paper and can trap more than 99 percent of pollen, dust and smoke particles. If germs, mold spores or wood burning fireplaces are a concern, a MERV 13 filter is recommended.

MERV 8 vs. MERV 11: What's the Difference?

A MERV 11 filter offers more filtration than a MERV 8 filter but does not filter as much as a MERV 13 (the highest option suggested for residential use).

If you're worried about the effects of inhaling fine air particles, a MERV 11 air filter is a better choice than a MERV 8 air filter. This model has a MERV 11 rating and helps prevent bacteria and viruses from entering the HVAC unit and spreading through the building. When choosing the best oven filters for allergies, you'll want to select a filter with a MERV rating between 11 and 13 for the best results. Raising just three levels of MERV rating can be beneficial in making air cleaner but can also restrict airflow due to the thickness of the filter material.
