Drum Air Purifier Filter Element Suitable for Mijia purifier 4pro
Compatible with Mijia Purifier Green Cylindrical Composite Filter, suitable for small and medium-sized rooms and office spaces, it can meet the air quality needs of home users and office environments. In addition to efficiently absorbing harmful gases and odors, it also uses electrostatic dust removal technology, which can absorb and remove tiny particles in the air, such as dust, pollen, and bacteria.
In order to ensure the normal function and service life of the filter, it is recommended to clean the filter regularly and avoid exposing the filter to direct sunlight. Users can refer to the product manual or manufacturer's recommendations for more guidance on use and maintenance.
Features
1. High-Efficiency Particulate Air (HEPA) Filtration
The filter utilizes a true HEPA-13 material, capturing 99.97% of airborne particles as small as 0.3 microns, including dust, pollen, and pet dander. Independent lab tests confirm a PM2.5 removal rate of ≥99.5% under standard conditions (CADR: 400m³/h). Its multi-layered structure includes a pre-filter, antibacterial layer, and activated carbon for comprehensive purification.
With a 6-8 month lifespan (based on 12-hour daily operation), this filter outperforms standard variants by 30%. It integrates with the Mijia app for real-time remaining usage percentage tracking, alerting users when efficiency drops below 85%. The anti-mold treatment extends durability in humid environments (tested at 30-80% RH).
The 1.2kg granular activated carbon layer features ≥800m²/g surface area, achieving 93% formaldehyde adsorption (24h test per GB/T 18801-2015). Specialized pore structures target volatile organic compounds (VOCs) like toluene (88% reduction) and nitrogen dioxide (85% efficiency).
Engineered with 3D pleated nanofiber technology, the filter maintains a ≤35Pa pressure drop at maximum airflow (tested at 60dB noise level). This optimizes the purifier's energy efficiency, reducing power consumption by 15% compared to conventional filters while maintaining 380m³/h clean air delivery rate (CADR).
An embedded silver ion antimicrobial coating inhibits bacterial growth with 99.9% effectiveness against E. coli and Staphylococcus aureus (per ISO 22196). The biocidal treatment remains active for the filter's entire lifespan without releasing harmful byproducts, verified by SGS testing
