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.
