Frigidaire CRA186MT20 Filter
The unit filter is designed to be good at trapping really small dust parts and other unwanted bits as it is being forced through the system. This simple filter can protect the unit and make it operate way more efficiently while also filtering the dust out of the air you breathe all day. Because of this, the filter should be swapped out for a new one or cleaned every so often depending on how much you use it.
Do you know if your primary air filter is about to stop working?
- The system filter looks brown and perhaps should be replaced real soon
- Light will barely break through to the other side of the filter at all
- It is highly advised to replace the filter about every 90 days to help purify the air indoors
