Friedrich CP18N30 Filter
The air filter is good at trapping really small dust parts and other tiny particles as it is being forced through the system. This can both keep the unit dust-free and make it operate a lot better at doing its job while also cleaning the air breathe in and out everyday. During regular maintenance the unit filter must be exchanged or simply cleaned every so often depending on how much you use it.
What are the clues to watch out for to know my dust filter is not working properly?
- The filter looks dusty and could be replaced right now
- When you hold it up, the light will almost not permeate to the other side of a completely clogged filter
- It is highly recommended to replace your air filter about every three months for clean air inside the house
