Following 2 types of air cleaning filters are used in this product. When you replace them, purchase dedicated air cleaning filters for this product.

Apple-catechin filter: UTR-FA16

(1 sheet)
The Apple-catechin filter uses static electricity to clean fine particles and dust in the air such as tobacco smoke and plant pollen that are too small to see.

• This filter is disposable. Do not wash or reuse it.
• Once you open the package, use it as soon as possible. The cleaning effect is reduced if the filter is left with the package opened.
• Replace the filter once every 3 months under normal use.
• By setting the fan speed high, the air cleaning effect increases.

Ion deodorization filter: UTR-FA16-2

(Light blue, 1 sheet)
The filter deodorizes by powerfully decomposing absorbed odors using the oxidizing and reducing effects of ions generated by the ultra-fine-particle ceramic.

To maintain the deodorizing effect, clean the filter once every 3 months as follows

1. Remove the filter.
2. Flush the filter with high-pressure hot water until the surface of the filter is covered with water.
3. Wash the filter gently with diluent neutral detergent. Do not wash it by wringing or rubbing to prevent reducing the deodorizing effect by damage.
4. Rinse the filter well with water flow.
5. Dry the filter thoroughly in a shaded place.
6. Reinstall the filter to the indoor unit.

Replace the filter once every 3 years under normal use.

After extended non-use of the unit
If you have shut down the indoor unit for 1 month or more, perform the FAN operation for half a day to dry the internal parts thoroughly before you perform normal operation.
