Clean and in place secondary pollution purifier should be regularly maintained
In order to maintain a healthy and clean indoor environment, many households have invested in air purifiers. However, without proper maintenance and disinfection, these devices can become a source of secondary pollution themselves. Wang Jinda, a professional in the home appliance repair industry, highlights that the filter elements inside air purifiers are where most bacteria and pollutants accumulate. Regular cleaning and maintenance are essential to ensure optimal performance and prevent the release of harmful particles back into the air.
To properly maintain an air purifier, it's important to follow the correct cleaning methods for each of its three layers. The first layer, usually a coarse filter, can be rinsed with clean water. If it's a thicker or more complex filter, it’s recommended to place it outside in direct sunlight for a few hours, depending on how long it has been in use. After drying, use a vacuum cleaner or a hair dryer to gently remove any dust that has settled on the mesh. This process should be repeated 2 to 3 times for best results.
Avoid shaking or tapping the filter directly, as this can damage its structure and reduce its effectiveness. The HEPA filter, which is responsible for capturing fine particles, should never be washed with water. Instead, it can be lightly cleaned using a vacuum cleaner to remove accumulated dust. The activated carbon layer, often found in catalytic filters, can be removed and exposed to sunlight for a short period to help restore its adsorption capacity.
Regular maintenance of all three layers not only improves the efficiency of the air purifier but also extends its lifespan. It's generally advisable to replace the HEPA filter and the activated carbon layer every 1 to 2 years, depending on usage and environmental conditions. By following these simple steps, users can ensure their air purifier continues to provide clean, safe air for their homes.
