This replacement filter pack (2-pack) for the Aroeve MK04 air purifier, specifically the Pet Dander Version (also labeled as customized for pollen and pet odors/allergies).This is a genuine Aroeve product, not a third-party knockoff. The box emphasizes that it's the official replacement to maintain optimal performance, perfect fit, and reliability, while warning against using unofficial/off-brand filters (which can lead to poor performance, lower CADR/efficiency, bad odors, wrong size, or even damage to the purifier).
Model compatibility: Designed for Aroeve MK04 and MK04W
Specialization: This is the "Pollen and Pet Allergy" / "Pet Dander Version" variant. It includes a special allergy filter layer with treatment/coating to better handle pollen, pet dander, pet hair, pet odors, and related allergens. It uses a multi-layer (often described as 4-in-1) system, typically including H13 True HEPA filtration to capture particles as small as 0.3 microns (like dust, smoke, dander, pollen), plus activated carbon or similar for odors/smells.
Replacement guidance: The box notes that the filter should generally be replaced every 3-6 months (or after ~2000 hours of use), when the air purifier's blue indicator light comes on. After installing a new one, long-press the reset button (often marked "⏎" or similar) to reset the filter lifespan counter.
Installation tips (shown in the diagrams): Pull out the filter cover, remove the old filter, unpack and insert the new one in the correct orientation/position, then slide it back in.
The Aroeve MK04 itself is a compact, popular tabletop/room air purifier (often praised for space-saving design and covering rooms up to around 400–1000+ sq ft depending on air changes per hour). It features easy filter access via a pull-out cover with a rope/handle.
