Panasonic CU-E18NKUA Air Filter
It is highly recommended that the air filter is replaced for a clean one every 3 months because the filter can get clogged and may result in poor air flow inside the house. The actual size of the filter is not a choice you make because it is based on the declared size of your air handler. Filters for your Panasonic CU-E18NKUA come in many filtering levels, depending on your demands for clean air and the specific size of filter you need for your system.
Some warnings your Panasonic air filter is failing
- It is highly recommended to swap out your air filter about every 90 days so as to have cleaner breathable air
- The unit air filter looks brown and it would be best to replace it immediately
- With a light behind the air filter, the light will hardly show on the other side a clogged air filter
