14x20x1, Percisionaire Ez Flow Ii Front Panel Merv 4, 10055.011420, Pack12

These filters are the best value. We used to buy expensive furnace filters, thinking they did a better job than the cheaper ones. We had a professional HVAC tell us to quit wasting our money on the high dollar filters. He said the biggest thing to do is replace the filter once a month (especially during the winter) because we have indoor pets. And the less expensive filters will do just fine. I have not noticed any difference with dust collecting in my home so I feel these filters are doing a good job. Don't waste your hard earned money because of the "HYPE" that other brands feed you.I will order these again.

work fine

Nice filter good airflow, great value for the money

I was getting these for an airbrushing booth and intended to use them as a prefilter to prevent some of the buildup on my merv 11 filters. Far too airy for that. Realized these are the same as I had got for my furnace, which maintains ample air flow, although it does need dusted a couple times a year.My mistake, but at least I can use them behind the blower to protect the motor from dust buildup in the shop. Good filters.

A somewhat hard to find size in a breathable filter more suited for our older AC system. Getting them by the case makes sense when you should be changing them every month or two.

On my order history it says that this package is arriving late. I received it on time. All is good. thank you.

I have been using these for a couple years. They fit and filter well.

good quality
