Replacement Filters

To keep the M-22 whole house air cleaner working efficiently the filters need to be inspected and replaced as needed. The M-22 uses 3 filters:  pre-filter, MERV 11 Media filter and activated carbon filter. The pre-filter can be washed and reused for quite some time. The media filter will likely need to be changed annually. The  activated carbon filter may need to be changed a little more often. To reduce the cost of replacement filters, we offer free shipping when you buy 3 filters. It is important to check the filters and replace them if they become full of dirt. If you do not replace dirty filters you can damage your fan motor.
