          Get a notice every 30 days to change the filter and for the cost its worth it. Were living in a construction site of NEW HOMES, and with the dust and soil partials in the air, its safer and best for the HVAC hardware to have the filter changed more offend.

                        We're waiting for one month installed to see how well it filters, but the store bought filters we were getting for our opening were always too large, often buckling the filter and causing whistling. This fit snugly but not too tight. Still happy with the price and the free shipping.
