Due to current air quality concerns, air purifiers have become extremely popular in our daily lives. Air filters ensure that the air inside our homes is continuously circulated, allowing us to breathe fresh air and improving our quality of life. Do you know what kind of filtration technology air purifiers use to clean the air? Here, I’d like to provide a brief overview of air filters.

Air purifiers are equipped with air filters, which are typically used to clean the air. These filters also require regular cleaning and maintenance. Let’s take a look at how to do it. I hope this information is helpful to everyone.

1. Simple air filter cleaning: Household air purifiers are equipped with a pre-filter, which typically only needs to be cleaned once or twice a month—this is the most convenient approach. During each cleaning, simply remove the filter and use a vacuum cleaner or a soft cloth to wipe away dust. Some pre-filters can even be rinsed directly under running water; alternatively, gently scrub them with a soft brush, shake off excess water, or blow-dry them thoroughly before reinstalling the filter in the air purifier.

2. HEPA air filters must not be washed with water: Filters that employ HEPA technology, unless explicitly stated otherwise, should never be washed. However, given the severe indoor air pollution prevalent in China, the service life of a HEPA filter is typically only about three months—or even shorter. In other words, HEPA filters need to be replaced frequently. Although these filters are relatively expensive, their lifespan can be extended through regular, timely cleaning during everyday use; nevertheless, once the filter has turned black, it must be replaced as soon as possible.

3. Regularly expose activated carbon to sunlight: While activated-carbon filters should be replaced regularly to prevent adsorption saturation, they can also be periodically removed and exposed to direct sunlight to naturally desorb and remove accumulated dust. For watch faces with heavy surface dust, wipe them with a soft cloth and then expose them to the sun for about three hours. Performing this maintenance routine regularly helps maintain excellent purification performance and prolongs the filter’s service life.

4. Active Nano-Microcrystal Purification Module: The active nano-microcrystal purification module (air filter) in household air purifiers should be replaced annually. However, if many people live in the home—especially if there are heavy smokers—it is best to replace it every six months.

The above is an introduction to the air purifier’s filter. It is crucial that we understand how to clean and maintain the air purifier’s filter if we want to extend the appliance’s service life. Here, we would like to remind everyone that air pollution is currently very severe, so it is essential to choose an air purifier carefully when making a purchase, as this directly affects the comfort and well-being of your family.
