Bests & Worsts Reviews from Amazon

My a/c unit needs an odd-sized filter, 18x20, that I can never find in stores. Lucky for me, here they are in a convenient 6-pack on Amazon. On top of that, they are a high MERV rating, not a flimsy piece of junk that is a filter in name only. These things catch a lot of dust, pet hair and soot from our fireplace. We can smell the difference in the house. I've seen popular-size filters with this high a MERV rating in the store for upwards of $20 each, so the average price of $8 for the size I need, plus free shipping right to my door, I was more than pleased. I've already ordered a second batch, and will do so again. I've taken a couple photos to show you all exactly how much dirt these things trap. We own cats, rabbits, and 2 fireplaces--lots of dust and hair in the air that killed our previous unit. These filters are catching it all.
