Are allergen filters bad for HVAC?
In most cases, high-efficiency filters (i.e., restrictive filters) won’t harm HVAC equipment, but they don’t offer as many benefits as a homeowner might believe. A PSC motor can only provide a certain level of air output, regardless of filter conditions.
Do Filtrete filters have a MERV rating?
The Filtrete Advanced Allergen , Filtrete™ Ultra Allergen , Filtrete Micro Allergen , and Filtrete Dust & Pollen are rated as MERV 12, MERV 11, MERV 11 and, MERV 8, respectively. 3M highlights the portion of the ASHRAE 52.2 test that focuses on sub-micron particles with its own performance rating.
Is MERV 11 better than 12?
We do not carry MERV 12; MERV 11 does just as good a job. MERV 12 filters trap 80 to 89 percent of average particles of 1.0 to 3.0 microns, with an average particle size efficiency of 90 percent or better. As you can see, they’re pretty close. That’s why you’re just as good going with a MERV 11 as with a MERV 12.
Can 3M air filters be used for masks?
3M does not recommend or support the use of a Filtrete™ Filter to make a mask or respirator because: Filtrete™ Brand products are designed to be used in home HVAC systems. It cannot achieve the fit or performance of an N95 respirator or a mask.
Do Allergen Air Filters Really Work?
JM: Air filters do work to trap particles, but it’s important to understand what they’re filtering. While these mechanical filters do trap small to large particles, studies have not been able to prove that effective filtering alone actually improves asthma or allergy symptoms.
Are MERV 13 filters bad for HVAC?
Filters within a MERV rating of 17-20 are almost never necessary in a residential home. A MERV rating of 13-16 is considered hospital level air quality, so it is unlikely your home needs any more than that.

Is MERV 13 too high?
MERV 13 air filters are the highest-rated air filters for home use. Any air filter with a rating higher than 13 will restrict air flow to the point of which could cause damage to your HVAC system, resulting in an added expense to fix it.
Can I replace MERV 12 with MERV 11?
In general no. In order to use a Merv 12 to replace a Merv 11, you need to know if you system can handle the extra pressure drop caused by the higher efficiency Merv 12. My heat pump/ ventilation system cannot support the pressure drop of a Merv 12. Compressors operated above design limit will die sooner than normal.
Is MERV 11 too high?
A MERV 11 air filter has a higher efficiency rating. Meaning, it can capture finer particles and clear more contaminants out of the air. In most cases, a MERV 11 air filter isn’t too high for residential use.
Are MERV-13 filters safe for face mask?
Higher than MERV-13 rated filters are not recommended as they offer little to no added protection while making it much more difficult to breathe. MERV-12 rated filters and below are 80% less effective at blocking sub-micron particles. Thus, MERV-13 is considered by most to be the optimal face mask filter.
