Is it possible to use a MERV 13 rated filter on the mini split units?Updated 24 days ago

We do not recommend using the MERV 13-rated filter.

The higher the grade of the filter, the denser the filter, while affecting the airflow, it is more likely to cause clogging. 

If the filter grade is too high, or dirty clogging is not cleaned in time, it will affect the cooling and heating effect, and also increase the risk of machine failure;
