The short answer is: yes!  But, read on to understand a little more about the ratings systems and why you should be changing your filters.

When you do your research on different filters, you’ll see that there are many different ratings systems that need to go into your decision.  Should you get a cheap $10 one, or should you spend $25?  What do you get for that extra $15?  We utilized the analysis done at one of our recommended local companies to decipher the different codes used in the air filter industry.

MERV, MPR, and FPR.  Those are the three ratings scales used in most residential air filters.  They have different scales, but they mostly all cover the same things: the levels of allergens and pollen they let through.  The higher the number, the better air quality you’ll have in your home.

Many people will buy the cheapest possible filters, thinking they’re all the same.  This is simply not the case.  In most cases, you’ll want at least a mid-range filter, if not a high quality one.  Seasons don’t particularly matter as there are different kinds of pollutants in the air.  In the spring and summer, it’s pollen.  Winter, you’ve got mold spores.

Year round, it’s important to make sure you’re changing your filters on the recommended timescales.  Without changing your filters, you should expect difficulties in breathing, especially to those with asthma or emphysema, or other related lung conditions.
