With the increasing problem of air pollution, more and more people are paying attention to air purifiers. The choice of filter, the core component of the air purifier, has become the key. 

In the selection of filters, HEPA filters and fiber cotton filters are common. So, which of these two filters is better? Let's learn about it together.

一. HEPA Filter 

HEPA filter can filter out particles with a diameter of 0.3 microns, with a filtration efficiency of more than 99.97%. Therefore, HEPA filters are widely used in hospitals, laboratories and other places.

二. Fiber Cotton Filter 

Fiber cotton filter is a kind of initial filter cotton, which can filter out particles with a diameter of more than 5 microns, with a filtration efficiency of about 80%. Fiber cotton filters are usually used in the pre-filter of air purifiers, which can filter out most of the dust, hair and other particles.

三. Which One is Better?

In terms of filtration efficiency, the HEPA filter is significantly better than the fiber cotton filter. However, the high filtration efficiency of the HEPA filter also means that it has high resistance and requires greater air volume to ensure air circulation. Therefore, the service life of the HEPA filter is relatively short and needs to be replaced regularly.

Although the filtration efficiency of the fiber cotton filter is not as good as that of the HEPA filter, its resistance is small, the service life is relatively long, and the replacement frequency is low.

Therefore, when choosing a filter, you need to choose according to your actual situation. If your family member has respiratory diseases such as asthma, or you need to use air purifiers in laboratories and other places, it is recommended to choose HEPA filters. If you just need to filter out dust, hair and other particulate matter in your home, then the fiber cotton filter can meet your needs.

In short, when choosing a filter, you need to choose according to your actual situation. At the same time, no matter which filter is selected, it needs to be replaced regularly to ensure the filtering effect of the air purifier.
