Friedrich SH20L30-B Filter
The air filter has the main responsibility for removing small dust molecules and other unwanted bits from the air in the house. This simple filter can keep the unit dust-free and make it run more efficient while also cleaning the air you breathe in your house. Because of this, the filter should probably be swapped out for a new one or perhaps cleaned thoroughly a few times a year in order to keep things clean.
Important signs the air filter needs to be replaced
- Many pros have recommended to replace your air filter every season of the year to help prevent bacteria from spreading too much
- The system air filter looks gray or brown and should be replaced right now
- As you face it toward a light source, it is unable to shine through the air filter
