finally a ac filter that "won me over"

well let's say ....I have used all filters from A to Z.....well this one ...not only did my ac air increase....but my electric bill decreased due to a filter that actually let's the system breath and overall run less and more efficient....this is my ac filter for life...ty Walmart !!

Great! Been using for many years!

Our home is 14.5 year old. We have been using these filters the entire time. Changing them regularly of course. Our duct work for the AC looks great. They are inexpensive. Our AC is still working fine. The inside looks just as clean and new as it sis when we had our house built. It's very dusty in Arizona. These have worked great for us.
