Besides filters, which parts of the air purifier need to be checked and replaced regularly?

Filter replacement intervals for air purifiers usually depend on the filter type, frequency of use, and air quality. Here are some common filter replacement intervals and what to look for when replacing them:

1. HEPA filter: 6 months to 1 year replacement is generally recommended, but in environments with poor air quality, more frequent replacement may be necessary.
2. Activated Carbon Filter: It is usually recommended to replace them once every 6-9 months, but their adsorption function can be restored by airing them out regularly.
3. primary filters: These filters are usually washable, and it is recommended that they be cleaned once a month for a service life of about a year.

There are a few things to keep in mind when replacing the filter:

• Choosing the right filter: Make sure you buy a filter that is compatible with your air purifier model.
• power failure operation: Always turn off and unplug the air purifier before replacing the filter to ensure safety.
• Cleaning the filter compartment: Before installing a new filter, clean the filter compartment to make sure it is free of dust and dirt.
• correct installation: Install the new filter correctly according to the instructions or directions, making sure it is securely fastened.
• Record the date of replacement: After replacing the filter, record the date of replacement to keep track of when the next replacement is due.
• Avoid secondary contamination: Try to avoid scattering dust and contaminants during the replacement process.
• Use original filters: Try to use original or certified replacement filters to ensure filtration.
• Disposal of used filters: Dispose of used filters in accordance with local regulations and pay attention to environmental protection.

In addition to the filter, other parts of the air purifier, such as the fan, motor, and housing, need to be checked and cleaned regularly. The fan and motor should be kept clean to avoid dust accumulation that can affect performance. The housing can be gently wiped with a soft dry cloth or vacuum cleaner attachment. If the air purifier is equipped with a sensor or display, it should also be properly cleaned and maintained according to the instructions.

Regular maintenance and replacement of filters not only ensures efficient operation of the air purifier, but also extends the life of the unit and reduces the risk of secondary contamination due to saturated filters.
