Review on 🌀 High-Efficiency AFB MERV Pleated Furnace Filter for Superior Filtration by Dave Rasic

I just installed. Everything seems fine. I have to switch every month no matter what. I live in Charleston, South Carolina. So my AC people told me to switch every month since we use our system all the time. It's so hot and humid here right now! If you live in a cooler climate you can use up to 3 months. But not us Southerners :(. I have an air purifier in my bedroom. Ever since I moved it from New York, I've had horrible allergies. So no matter how expensive the filter I use is, I still had to buy an air purifier, but that seems good.
