Please pay attention to the iden-
tifier of the filter when cleaning

The incisions of sheet metal and resin
parts, as well as bulges and sharp
corners of the product, may cause
injury.
Otherwise, the purification efficiency
may decrease.

About the service life of the filter
Cleaning

Protect your eyes when cleaning or replacing the
filter. Otherwise, dust attached on the filter may
enter your eyes. If necessary wear eye protection.
To prevent the dust adsorbed on the filter from diffusing in the room during cleaning, please clean
the filter outdoors or use a vacuum cleaner that can remove PM2.5 particles.
The service life of filter is set based on the operation of 10 hours every day.
The air volume and purification efficiency may decrease depending on the operating environment
and time. When cleaning the outdoor filters, if you observe that the side to which the arrows of the
outdoor filters point become black, please replace the outdoor filters in time.
If the product is used in an excellent environment and the concentration of particles with diameter
below 2.5 µm is lower than 50 µ

, the deviation of test data may be large due to the accuracy
of the test instrument, leading to the decrease of the purification efficiency calculated based on the
above test data.
If the energy recovery ventilator is used for a long time, the outdoor filters of the energy recovery
ventilator will be blocked by dirt and dust, which will cause the decrease of the air exchange volume
and air exchange effect, leading to louder noise. Please clean the outdoor filters regularly according
to the amount of dirt and dust attached to the filters.
If the product is used in a harsh environment (dusty area), the air volume and purification
efficiency of the product may decrease drastically. To maintain the performance of the product,
please increase the frequency of cleaning or replacing the outdoor filter appropriately.
The replacement standard is evaluated according to the independent benchmark of the company.
The actual operating environment may be different.
The test instrument used by the company is TSI 8530.
