I have been dealing with Filterbuy for a few years. The service and quality is absolutely fantastic. I can't think of better people I have dealt with in business . Over the years the business has grown and the service and quality has not changed.

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.

I needed a new filter for my furnace, and the local big box stores and local hardware stores did not have my size. I looked on line and FilterBuy' s responses were quick and all was accomplished.
