Our HVAC company confirmed that Filterbuy is their source. The prior home had electronic filters to wash in the driveway.

Work well

I live in the country. Dust and dogs major issues. I change my filter every 3 months. Need it to. I wipe my finger on the filtered pipe as I change filter. I get a film but nothing really.
Good filter. Good price. Easy to order instead of driving around looking for one.
