ROUNY H13 HEPA Air Filter Cartridge Replacement for Air Purifier AP-T1 AP-T2 Original

ROUNY H13 HEPA Air Filter Cartridge Compatibility and Filtration Specifications

True H13 HEPA filtration grade is the defining specification here — it is the same medical-grade standard used in clinical air-handling systems, and it guarantees particle capture efficiency that lower-grade filters sold by third parties cannot reliably match. This cartridge is compatible with AP-T1 and AP-T2 purifier models, slotting in via the original mounting frame with no modification or adaptor required. At 99.97% capture of fine particles at 0.3 microns, the filter removes ultra-fine urban pollution particulates, seasonal pollen, and mould spores that standard HEPA-style filters allow through. Using a genuine replacement part preserves the manufacturer-tested airflow resistance rating, which keeps your purifier motor running within its designed operating range and extends the unit lifespan. Replace the cartridge every six to twelve months depending on local air quality and usage hours to maintain peak indoor air performance in your home or office.
