I installed first filter at the beginning of June, so I haven’t had time to make a decision yet. I did buy 3 month filter but due to having 3 dogs I was instructed by A/C tech to still change every month.

It was just what I needed. I was unable to find the right size filters for my home AC/Furnace at the local hardware stores.
I am very pleased with the purchase.

I liked the quickness of delivery, but the size is not as described. It lacks the actual 20" x 24" x 1". The 1" is fine the others are just about 1/8" short, so I had to add folded cardboard to make up difference to fit in frame. Otherwise they are good.
