PreVent AC Filter
Six of One, Half a Dozen on the Other
I purchased this filter last year and have noticed how many tiny bits of debris it's caught since then. Normally that debris would have gotten into my unit, but now I can just brush it off.
So if my unit's air flow has to be restricted, the restriction might as well occur on the outside where I can rinse off the mess, than on the inside, where I have to call someone to come clean it.
The filter itself barely restricts any air anyway. Just look at the numbers on the packaging.

Ridiculous waste of money
In order to filter the air, this device, by design, must be restrictive. Restiction of airflow through the condensing coil, whether by outdoor dust and debris, or by this filter will cause the unit to work harder and consume more energy. Having the unit serviced by a professional annually is the only way to improve performance

I thought my a/c unit was needing to be replaced. I had the unit serviced and was taking to the repair man and he told me that he has one on his unit at home. I noticed change in my utility bill the next month.
