These are some of the best filters available. The price is competitive and definitely better than what you can get at retail stores. I buy a year's supply for by two units (house is upstairs/downstairs). I do notice a difference in the air and cleanliness of the house. Worth it.

My Climate Master geothermal air handler uses a filter with actual dimensions of 29. 5x31. 5x1. 75 inches. I had to cut the Filterbuy down to size to get it into place. Seems to be working ok, but its a nuisance.
