🌬️ Purify Your Air with Aerostar 20X20X1 MERV Pleated Filter: Enhance Your Indoor Air Quality Review

My local friend (like me) thought MERV 8 should be fine and not harm my system. The filters arrived today and I did an airflow test through my

These filters are true to size and fit perfectly in my ceiling vents. I have to change 5 filters every time and having them shipped to my home in bulk works great. I have found that a MERV of 8 is ideal for most homes. Anything lower won't filter as much, and anything over 8 can make your heating/cooling system too heavy and not as efficient. If anyone else knows, please report. This is just information I have gathered while researching the meaning of MERV. I will buy them in the sizes I need…
