Choosing The Most Appropriate MERV Rating For Your Air Filter System

 

Irrespective of the type of air filter that you have, it is most likely the case that it is equipped with an air filter. An air filter, as most you are already aware is used to get rid of all the harmful and unwanted particles from air. While you are going to choose an air filter, you need to determine the best air filter MERV rating for that. That is what we are going to help you with in the next part of the post.

 

According to most experts, using an air filter that is rated in between MERV 5 to MERV 8 is going to work out for most residential homes. The air filters that rated in this range are effective in getting rid of pollen, mold spores as well as dust. Also, using these air filters would make your HVAC system more efficient than using higher rated filters. Having said that, you need to take up the responsibility to replace the filters at regular intervals.

 

If you are someone who suffers from respiratory conditions or have some kind of allergies, then using an air filter which is rated in between MERV 10 to MERV 12 is advisable. These filters can trap particles of sizes around 1 micron.

 MERV filter ratings in between 1 to 4 are the most basic filters that are partially able to block carpet fibers and lint. The ones ranging in between 5 to 8 are usual filters and they are the most commonly seen air filters. MERV 9 to 12 rated filters are better filters that are also recommended for individuals having some kind of allergy.
