The difference between Xiaomi's High Efficiency Filter and a conventional HEPA Filter

Combination of two filter technologies: Electrostatic and mechanical filtration. Xiaomi's High Efficiency Filter media can remove 99.97% of airborne particles as small as 0.1 micrometres and traps dust, PM 2.5, pollen, pet dander, smoke and even the smallest microplastics. The filtration rate of Xiaomi's High Efficiency Filter media is 99.97% for fine particles of up to 0.3 microns, and can reach up to 99.99% for particles as small as 0.1 microns.

Disclaimer: Filter media performance is tested by China Testing & Inspection Institute for Household Electric Appliances (Report Number: WCv-21-40115). Due to the technical specifications of the filter media, the test environment and parameters may differ.

Air Purifier Purchasing Guide

* 16–27m² effective coverage area: As calculated in Air Purifier (GB/T 18801-2015) Appendix F.4: Area of application = pCADR x (0.07–0.12). pCADR data from CVC Testing Technology Ltd. Report no.: WTS2022-4212.

*Traps 99.97% 0.3μm particles: According to the China Testing & Inspection Institute for Household Electric Appliances Inspection Report (No. WCv-21-40115), the filter material used for this product achieved a filtration efficiency of 99.97% for 0.3μm particles.

* 230m³/h Particle CADR: Data from CVC Testing Technology Ltd. Report no.: WTS2022-4212.

* Low-noise 20dB Sleep Mode: Refers to the noise value generated when the product is in Sleep Mode. Data from CVC Testing Technology Ltd. Report no.: WTS2022-4212.

* Only 0.7kWh are needed for 24 hours of purification: 27W x 24h ÷ 1000 = 0.684kWh. 24h power consumption of 0.684kWh, approximately 0.7kWh.

*Alexa is not available in all languages and countries. Alexa features and functionality may vary by location. Please refer to official website for more information.

*48 ㎡ room size is base on 2 air changes per hour(ACPH), meaning that it can purify a 48 m² room 2 times per hour(assuming the room has a ceiling height of 2.4 m), room size = pCADR ÷ 2.4 m÷2. pCADR data from CVC Testing Technology Ltd. Report no.: WTS2022-4212.

* Room size(up to) is calculated based on 2 air changes per hour(ACPH) and PCADR, meaning that it can purify a room of this size 2 times per hour(assuming the room has a ceiling height of 2.4 m), Room size = PCADR ÷ 2.4 m÷2.

* Effective coverage area is calculated according to the Chinese national standard GB/T 18801-2015, assuming the room has a ceiling height of 2.4 m and considering factors such as the outdoor particulate pollutant concentration of 300μg/m³ and the number of air changes in buildings, the standard is more stringent. Effective coverage area=(0.07~0.12)*PCADR.
