Clean and in place secondary pollution purifier should be regularly maintained
In order to maintain a healthy and clean indoor environment, many families have invested in air purifiers. However, neglecting regular maintenance can lead to secondary pollution, defeating the purpose of using the device in the first place. Wang Jinda, an expert in home appliance repair, emphasizes that the filter elements inside air purifiers are the primary area where dust, allergens, and bacteria accumulate. To ensure optimal performance, it's crucial to clean and maintain these filters regularly.
Proper cleaning of the air purifier involves careful attention to each of its three layers. The pre-filter, which captures large particles like dust and hair, can be rinsed with clean water. If the filter is thick or multi-layered, it should be placed in direct sunlight for several hours to dry naturally. After drying, use a vacuum cleaner or a hair dryer to remove any remaining dust from the mesh. This process should be repeated 2–3 times for best results. Avoid shaking or tapping the filter, as this may damage its structure and reduce its efficiency.
The HEPA filter, responsible for trapping fine particles, should never be washed with water. Instead, it can be gently cleaned using a vacuum cleaner. For the activated carbon layer found in catalytic filters, it’s recommended to remove it and expose it to sunlight for a few hours to help restore its effectiveness. By following these maintenance steps on a regular basis, the lifespan of your air purifier can be significantly extended.
Generally, after 1–2 years of use, it’s advisable to replace the HEPA filter and the activated carbon layer to maintain the unit’s performance. Regular care not only improves air quality but also ensures that your investment in an air purifier continues to deliver long-term benefits.
