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.
What FPR should I use?
The logical choice (according to the chart) is to find a better filter with a higher MERV rating. A higher MERV rating improves filtration effectiveness by trapping more particles─ which is why a tighter weave is more effective. Stick to MERV ratings of 8 and 11, or MPR 600 – 1200 and FPR of 5 or 7.
What MERV rating is FPR 7?
MERV 11 is equal to FPR of 7.
What does fpr 10 mean on an air filter?
FPR Rating 10 (Premium) Filters our large particles in the home like dust, link, dust mites, larger pollen particles, and pet dander. Also filters out small particles like bacteria and mold spores. These filters also remove smoke, smog, allergens, and some particles that can carry viruses.
What is an FPR rating?
The acronym FPR stands for filter performance rating. The FPR rating was developed by The Home Depot and is used for brands of HVAC air filters sold in its stores. FPR ratings are expressed in number and color. The FPR ratings scale for HVAC air filters starts four and ends at 10.
Is FPR 5 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.
Is FPR 4 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.
What is FPR and MPR?
MPR, or Micro-Particle Performance Rating, pertains only to products developed by the 3M company; typical MPR ratings range from 300 to 2200. 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.
What is the FPR of a premium air filter?
Premium Air Filters: FPR 10 filter out: Particles like household dust, lint, dust mites, pollen and pet dander. Small particles like bacteria and mold spores. Smoke, smog, microscopic allergens plus particles that can carry viruses.
Is MERV 13 too high?
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.
How often do you change air filter?
Here are averages that may help you know how regularly you should get a new air filter at your residence: Vacation house or one occupant and no pets or allergies: every 6–12 months. Ordinary suburban home without pets: every 90 days. One dog or cat: every 60 days.
What is MERV rating for Covid?
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 11 or 13 better?
A MERV 11 rated furnace filter can trap the majority of harmful contaminants that are present in the air. A MERV 13 filter is capable of filtering out all particle impurities like dust, lint, pollen, mold, dust mites, pet dander, smog, and smoke. On top of this, it can also trap bacteria and viruses.
Does MERV 13 restrict air flow?
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 better than 12?
The difference between 11 and 12, therefore, is quite negligible. 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.
Can my furnace handle a MERV 13 filter?
The ideal MERV filters for both air filtering and furnace efficiency are 7-13, experts say. These filters can be used without any modifications to your equipment. Your system may handle MERV 14-16 with no discernable stress. However, many residential systems require modifications to pull air through these filters.
What does MERV 11 mean?
The MERV 11 will increase indoor air quality by removing 85% of micron sized contaminants in the air which maintains the efficiency of the HVAC unit. It is also highly recommended if there are pets in the home which can greatly reduce the air quality indoors.
Does MPR matter air filter?
Comparison of air filter MPR ratings The higher the MPR rating, the more particles a filter blocks. Filters with a low MPR rating are only able to filter out large particles such as lint and hair. Higher MPR ratings bring more air filtration, especially with small microscopic particles.
Does MERV 11 restrict airflow?
A MERV 11 air filter has a higher efficiency rating. Air filters with higher MERV ratings can filter more, but the thickness of the filter material can restrict airflow. Restricted airflow can decrease comfort, increase energy use, and accelerate the wear and tear of HVAC components.
