Carrier 38H Air Filter
It is advised that the filter is swapped out every 3 months so as to maintain good airflow inside the house. Carrier 38H filters exist in many different styles and sizings, depending on your choice for how clean you want the air and whether anyone suffers from allergies in the home. Exact measurements of the filter is not a choice you make because it is based on the declared size of your furnace or handler.
How do you know when your filter is in need of replacing?
- It is highly suggested to swap out your air filter four times a year to help purify the air indoors
- The unit air filter looks bad and could be replaced immediately
- If you lift the air filter up to a source of bright light, the light cannot breach the other side of a clogged air filter
