I am often shocked by the prices being charged for these whole house filter cartridges online and in the big box stores such as Lowes and Home Depot. I just cant bring myself to tske advantage of peoples needs to make a huge profit. The cost of our five micron belt blown whole house cartridges is half that found at Home Depot for what is essentially the same product. Home Depot is charging $9.97 for the HDX Household Melt-Blown Filters 2-Pack (Paquete de 2 filtros de soplado en fusion para el hogar). At that price our filters are more than 50% less expensive! You can order these replacement cartridges direct from our website.
