The MERV 11 pleated air

The MERV 11 pleated air filter is high quality and catches a large amount of dust.

We really like your filters but due to your recent price hike we are unable to afford them and we had to cancel our account. We are seniors on limited funds.

Not sure
on June 17, 2026
Posted by: Customer
I'm not sure what i was expecting. They were packaged poorly and bent up. Seemed cheap. But they definitely aren't.
Nor what i was expecting. Packaged poorly and the filters were crushed.

While I’m a recent customer

While I’m a recent customer I am impressed with the quality and value of your filters. My HVAC uses an odd size but your company has it in stock and you ship very quickly. I’m well stocked so I’ll re-order in about six months.
