Here are the steps to measuring your air filter size:
- Measure the length of the air filter cabinet
- Measure the width of the air filter cabinet
- Measure the depth of the air filter cabinet
Now you have the three most important air filter dimensions!
Air filter dimensions in order: Length (L) x Width (W) x Depth (D)
You will usually find an air filter that will fit your cabinet size. Air filter lengths generally range from 10″- 20″, air filter widths generally range from 20″-25″, and depth usually ranges from 1″-4″.
MERV stands for Minimum Efficiency Reporting Value. MERV ratings are regulated by the ASHRAE (the American Society of Heating, Refrigerating, and Air conditioning Engineers). The ASHRAE regulates all furnace filters for sale in the US and mandates that MERV rating be placed on each filter.
MERV ratings measure the worst possible performance of an air filter. These ratings range from 1-16 and are based on the ability to filter particles .3 to 10 microns in size. The rating is determined based on a set of three different percentages. The first percentage (level 3) is based on the ability to filter particles that are from 3-10 microns in size, the second percentage (level 2) is based on the ability to filter particles from 1-3 microns in size, and the last percentage (level 1) is based on the ability to filter particles from .3-1 microns.
Understanding MERV Ratings
The higher the MERV rating the better. MERV ratings range from 1-16. A good MERV rating ranges from 11-13, and a very good MERV rating ranges from 13-16.
MPR stands for Microparticle Performance Rating. The MPR rating is not used for every type of filter. The only brand of filters that use MPR ratings are 3M filters. They have developed their own performance ratings.
MPR Rating to MERV Rating Comparison Chart
- MERV 6 = MPR 300
- MERV 8 = MPR 600
- MERV 11 = MPR 1000-1200
- MERV 13 = MPR 1500-1900
Do furnace filters help allergies?
AC Furnace air filters with high MERV ratings help allergies by capturing micro particles such as pollen, dust, mold spores, and pet dander. A filter with a MERV rating of 9-12 and higher will effectively reduce allergens because it is able to capture up to 95% of smaller particles.
What MERV rating should I buy for allergies?
The best MERV rating for to buy for allergies ranges from 9-13. A furnace filter with a MERV rating of this magnitude should capture 95% or more of micro particles that produce allergies.

Do higher MERV filters restrict airflow?
Higher MERV HVAC filters can restrict airflow and result in increased energy bills. It is important to weigh the benefits and downfalls of high MERV filters. A higher MERV means that it will effectively filter allergens and small particles, but may reduce airflow and result in a higher energy bill.
Recommended MERV Rating for Pollen, Pet Dander, Dust and Mold
The recommended MERV rating for pollen is 9-12. A filter with a MERV rating in this range will eliminate 95% of particles that flow through the furnace filter. In theory, this means that allergy symptoms should significantly reduce in your home.
