Choose the right filter type
The classic air purifier is equipped with a HEPA filter. For some specific needs, some may have other filters. The following are terms and definitions:
1. Pre-filter: A basic function of air purifiers using HEPA filters. The pre-filter can collect a lot of dust and pet dander to help extend the life of the main filter. Most pre-filters are washable and reusable, and have a long service life.
2. Ture HEPA filter: This is a high standard air filter. In order to carry this label, the filter must meet the strict regulations established by the US Department of Energy (DOE) and capture at least 99.97% of particles as small as 0.3 microns. After 6 months to 1 year, the Ture HEPA filter needs to be replaced, and a suitable replacement should be used for the air purifier.
3. Activated carbon (or charcoal) filter: This filter can absorb odor particles and gas. This is why it can remove odors from smoke, pets, cooking, formaldehyde chemicals, etc.
4. Ion filter (or ionizer: This filter emits negative ions to charge small particles (such as dust, pollen and bacteria) and collect them in the plate.
5. UV・C lamp-ultraviolet: eliminate bacteria and viruses by sterilizing them. UV-CCT (C-type ultraviolet) is harmless to the human body.
6. Advanced BioGS HEPA filter: RabbitAi is a technology that helps to extend the life of a real HEPA filter.
7. Permanent HEPA filter: A technology of Hamilton Beach that can clean its HEPA filter by vacuum, so you don't need to replace its HEPA filter.
8. HEPA filter: This filter is a lower quality version of the Ture HEPA filter and does not meet the above-mentioned standards set by the US Department of Energy.
 

    

ACH stands for "air changes per hour"
The ACH evaluation indicates the air exchange rate and tells you how many times the device can exchange air with clean, fresh air every hour in the room. For example, 4X means that the device cleans the air four times per hour.
Common ACH ratings in the best air purifiers are 4x, 5x, 6x, etc.
Please keep in mind that the air purifier ACH marked is usually used when the maximum fan speed is used.
 
CADR stands for "Clean Air Delivery Rate"
The CADR developed by the Association of Household Appliance Manufacturers (AHAM) stands for "Clean Air Transfer Rate", which accurately describes the ability of an air purifier to clean air in a room of a specific size.
For example, an air purifier with the following CADR: dust/500 cfm, pollen/640 cfm and smoke/500 cfm (or 500 dust/500 smoke/640 pollen) usually covers 65 to 74 square meters.
