Air Filter
Common Questions
What does the air filter in a mini split do?
The air filter inside your indoor air handler catches dust, pet hair, and debris before they reach the coil. Most mini split filters are washable mesh screens — you slide them out, rinse them off, and put them back.
How often should mini split filters be cleaned?
A good rule of thumb is every two to four weeks during heavy use. How often you actually need to clean them depends on how much you run the system and what is in your air, so pets and dust push that interval shorter.
What happens if the filter stays dirty?
A clogged filter restricts airflow, which causes the evaporator coil to ice over and can lead to water leaking from the unit. Cleaning it is the easiest maintenance item to stay on top of, and skipping it creates the expensive problems.
