FPR, or Filter Performance Rating is a system that specifically developed for The Home Depot (developed by 3M) and only pertains to the brands that are sold in their stores. The rating system is actually similar to MERV.
Is FPR 5 the same as MERV 8?
FPR 4 -5 is the same as MERV Ratings 6 – 8. FPR 6 – 7 is the same as MERV Ratings 8 – 11. FPR 8 – 9 is the same as MERV Rating 11. FPR 10 is the same as MERV Ratings 13.
What FPR is MERV 13?
MERV 13 filters are equal to an FPR rating of 10.
Is higher FPR filter better?
High-efficiency filters
A more efficient filter will be more effective at removing particles from the air as they enter your HVAC system. They will improve the air quality in your home as well and keep your lungs happy.
Is FPR 4 good enough?
FPR 4-5 (Green = Good): These filters are able to capture large particles such as dust, dust mites, lint, pollen and dander. FPR 6-7 (Red = Better): These filters are able to capture large particles and small particles such as bacteria and mold spores.
What FPR rating is best?
While FPR’s rating system goes from 1 to 10, MERV’s rating system goes from 1 to 20. FPR 10 is similar in strength to MERV 20, since they are both the highest rating value.
Is FPR 7 GOOD?
According to Home Depot, filters in the “Good” class are rated listed as FPR 4, and they will block pet dander, dust, and pollen. The next tier is the Better represents 6 – 7, but is listed at 7 FPR, and adds protection against bacteria along with mold spores.
What does FPR mean on an air filter?
FPR, or filter performance rating, labels filters based on a number scale from 4 through 10 in addition to a color-coding system. Designed by The Home Depot for brands sold through their stores, including Honeywell, this rating structure is very similar to MERV rating.
Is MERV 8 too restrictive?
In many cases, a MERV 8 air filter is more than adequate. However, if you are worried about outdoor air pollution, family members with respiratory issues, pets are in the home, then going with a higher MERV rating might be a good idea.
Will MERV 13 filter coronavirus?
What kind of filter should I use in my home HVAC system to help protect my family from COVID-19? Minimum Efficiency Reporting Values, or MERV, reports a filter’s ability to capture particles. Filters with MERV-13 or higher ratings can trap smaller particles, including viruses.
Is MERV 13 too restrictive?
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.
Is MERV 11 or 13 better?
MERV 11 furnace filters have a particle arrestance of a little over 90%. In comparison, MERV 13 HVAC filters have a particle arrestance of around 98%. Naturally, it is significantly more efficient. MERV 11 rated air filters are ideal for those who live in a moderately polluted area, have mild allergies, or own a pet.
Is there a downside to high MERV filters?
Wrong. While the highest MERV ratings are the most effective for air quality, they can harm your HVAC system. A higher MERV rating means a higher resistance, which means less airflow. When researching HVAC systems, airflow will come up a lot.
Does MERV 11 restrict air flow?
Be aware, too, that some retailers also use their own rating system instead of MERV. A decade ago, it used to be that if you had an HVAC system that used panel filters rated 6 through 9 MERV, putting in a MERV 11 or higher filter would restrict airflow (known as filter pressure drop).
Does MERV 8 filter smoke?
However, a MERV 8 filter captures less than 20% of particles smaller than 0.3 microns. That means things like pet dander, smoke, and some airborne bacteria are likely to get through a MERV 8 filter.
Can you double up air filters?
Can You Stack Air Filters? Do not stack multiple smaller air filters on top of one another to fit them into a larger air handler. Installing multiple 1” air filters in a 2” slot, for example, can cause costly damage to your AC unit, as residential furnaces are not equipped to handle this level of airflow restriction.
What does FPR stand for?
FPR, or Filter Performance Rating, is a filter rating system developed by Home Depot for the brands sold through its stores, including Honeywell; it uses a 1-10 rating scale.
