Fujitsu ASU9RMLQ Air Filter
Filters come in a wide array of varieties and specific sizes, in which the one you choose will depend on your demands for clean air and air handler size requirements. It is suggested that the air filter is swapped out every 90 days or so due to the filter clogging up and restricting the flow of air inside the house. Measurements of the air filter can not be a optional choice due to the requirement of your HVAC blower system.
