1. Filtration Technology
- Mi Air Purifier: Most Mi models, like the Xiaomi Smart Air Purifier 4 Pro, use a 3-stage filtration system (pre-filter, true HEPA H13, activated carbon) that removes 99.97% of particles as small as 0.3 microns, including dust, pollen, and pet dander. Some models, like the Mijia Air Purifier 5S, also target volatile organic compounds (VOCs) and formaldehyde.
- LG Air Purifier: LG’s PuriCare models, such as the AeroTower, feature a multi-stage filtration system with a true HEPA filter and UVnano technology to kill 99.99% of bacteria on fan blades. They excel at removing bacteria, viruses, and ultrafine dust, with some models eliminating up to 99.9% of harmful particles.
Verdict: Both brands offer true HEPA filtration, but LG’s UVnano technology gives it an edge for bacteria and virus elimination, while Mi’s VOC and formaldehyde focus is ideal for chemical-sensitive environments.
2. Room Coverage
- Mi Air Purifier: Mi purifiers cover a range of room sizes. The Xiaomi Smart Air Purifier 4 Lite is suitable for up to 45 square meters (484 sq. ft.), while the Mi Air Purifier Pro H covers up to 72 square meters (775 sq. ft.) with a CADR of 600 m³/h.
- LG Air Purifier: LG’s PuriCare AeroTower covers up to 818 square feet, and the PuriCare 360 Alpha PET Double can handle larger spaces with 360-degree suction. These are better suited for large rooms or open-plan homes.
