The concentration of ozone generated by power equipment should not exceed the specified requirements.

Determine whether it is qualified through the following tests:

Conduct the experiment in a sealed room with dimensions of:2.5m×3.5m×3.0mThe wall surface is covered with polyethylene sheet, and the air purifier is placed according to the instructions. The air purifier used on the desktop is placed at a height of about from the floor750mmYang in the room.

The room maintains a temperature of approximately25℃ and relative humidity are approximately50%The air purifier is powered on at rated voltage24hIf the removal of the filter is in a less favorable state, the filter should be removed.

The ozone sampling tube is set at a distance from the air outlet of the air purifier50mmAt the beginning of the experiment, measure the background ozone concentration first, and then subtract the background ozone concentration from the ZUI concentration measured during the experiment.

The percentage of ozone concentration should not exceed5×10^-6

Note: If the installation manual specifies that the volume of the room where the air purifier is installed exceeds30m³The size of the experimental room should be increased accordingly.
