What is the Air Filter MERV rating?
MERV is an acronym for Minimum Efficiency Rating Value. It provides a scale which shows the worst case performance of an air filter removing small particles in the range of 0.3 to 10 micrometres. For the detail oriented person reading this, MERV was developed by the American Society of Heating, Refrigerating and Air-Conditioning Engineers. In simple terms, it rates the efficiency of the air filter. The MERV Rating scale is between 1 and 16. We supply filters with MERV Ratings from 5 to 13, that means we can provide the air filter you need based on the particles you want filtered from the air. The higher the MERV rating, the more effective the air filter is at capturing smaller particles of allergens. More on MERV Ratings.

The Importance of Changing Your Furnace Air Filter
Only about 1 in 5 homeowners pay attention to what is perhaps the most important of household maintenance tasks. It is important to remember that changing your furnace air filter regulary will extend the life of your furnace. Given the difference in price, changing your air filter reguarly only makes sense. When your furnace is struggling with a dirty air filter it is not getting a supply of fresh household air passing over the heat exchanger and the heat does not get dispersed as it needs. This means the heat exchanger cannot get rid of its heat and the exchanger itself overheats causing heat damage to the exchanger and ruining your furnace.

It can be confusing when you are looking for the right size furnace air filter or any other air filter for that matter. There is a wider ange of sizes and types. Something that is relatively easy to grasp once you know the information is that the air filter size is not necessarily the real size. For instance a 20x22x1 air filter has an actual size of 19-1/2" x 21-1/2" x 3/4". The measurments on the air filter are rounded up for ease of understanding.
