Please operate this air purifier according to the instructions in the user manual. To purify the air more quickly, we recommend running the air purifier with the maximum airflow for at least 30 minutes after the air purifier starts.
By using the HEPA filter, the air purifier can efficiently filter out particles as small as 0.02 microns (100 times smaller than PM2.5), and remove harmful substances in the air. The filter can absorb and remove airbone bacteria, pollen, formaldehyde, TVOCs, and other harmful substances. The air purifier satisfies the needs of the younger generation who pay attention to healthy life.
The air purifier has four advanced filtration methods, namely, sieving filtration, inertial collision, active interception and diffusion adsorption. Moreover, it features a special activated carbon filter with plenty of nano-scale micropores, most of which are smaller than 2 nanometers. As a result, the air purifier is able to efficiently filter formaldehyde, toluene, and other volatile organic compounds.
Regularly replace or clean the filter to ensure the purification effect, and avoid the secondary discharge of pollutants absorbed by the filter.
When using the air purifier to remove indoor airbone pollutants, please keep the doors and windows are closed to avoid the air circulation between the indoor and outdoor. For long-term use, please ventilate the space periodically.
Before turning on the air purifier that has not been used for a long time, please clean the inside parts and check the conditions of the filter. Replace the filter if necessary.
It may be a filter alarm, indicating that the filter needs to be reset. Generally speaking, the filter should be replaced every 3-6 months to ensure optimal purification efficiency. After replacing the filter, please follow the instructions in the manual to reset it.
The sensor needs to be replaced.

The portable air conditioners cool the room partially. They cannot reduce the whole room temperature like cabinet air conditioners.
Lengthen the inlet and outlet pipes of the condenser and evaporator to make them penetrate deep into the inside to improve the resistance of the copper pipes.
Check whether the air blown from the air outlet is cold or not. If not, please check whether the filter is dirty, or whether the heat dissipation is blocked. These two aspects will affect the cooling effect; If the fan or motor is broken, or the compressor does not start, the air conditioner cannot cool down the room, either. If there is cold air blown out from the outlet, some other reasons like an extra-large room, high ambient temperature, high-heat source, or connecting to the outdoors may also make you feel that the room temperature is not decreasing.
