Replacement Air Filter for Airmax KoiAir KA20, 2-Pack The intake air filter on the KA20 aerator blocks dust, pollen, and airborne debris before they reach the compressor diaphragm. A clogged filter reduces airflow, drops dissolved oxygen output in the pond, and shortens diaphragm life. This 2-pack provides a full year of filter changes for the KoiAir KA20, or two replacements if your pond environment is particularly dusty. Compatible With Airmax KoiAir KA20 aerator Quantity 2 filters Replacement Frequency Every 6 to 12 months; more often in dusty environments How to Replace Unplug the aerator. Locate the air intake port on the compressor housing. Remove the old filter and discard it. Do not attempt to clean and reuse foam intake filters, as embedded particles reduce airflow even after rinsing. Seat the new filter in the intake housing and restart the aerator. Check air output at the diffuser to confirm improved flow after replacement. Fits the Airmax KoiAir KA20 aerator only. Check the diffuser output and listen for labored compressor sounds as signs of a clogged filter. Stock a spare so filter changes do not interrupt aeration.
