1. Most air purifiers come with a filter replacement indicator. When the filter indicator is on, it means that the filter needs to be replaced. However, the filter indicator lights of many air purifiers cannot detect these situations, and it depends on the actual situation.
2. When the user feels that the purification effect is not obvious, it is necessary to replace the adsorption or filter material, usually once a year. If the pollution is heavier, it should be replaced every 3 to 6 months. Also, if the filter material turns black after turning off the purifier and power supply, it also means that it needs to be replaced.

3. The pre-filter of the air purifier can be washed with clean water. After cleaning, it needs to be dried or blown dry before being loaded into the air purifier. You can also use a rag or a vacuum cleaner to remove dust.

4. For the washable deodorizing filter, it can be rinsed under the tap. In a newly renovated room, the formaldehyde removal filter has a large loss and needs to be replaced once a year. Generally speaking, the service life of the HEPA filter is as long as 10 years, and it is generally recommended to replace it every 2-5 years. If the pollution is heavy, the replacement frequency should be increased.

The air purifier is now a relatively fashionable home appliance. In order to achieve better purification efficiency and ensure the service life of the purifier, regular cleaning and replacement is necessary.
