Introducing the Personal Air Purifier, it's how makes clean air easy! Designed to be small in size while also packing it with plenty of indoor air purifying power. MYair has a 3-in-1 High Efficiency, Activated Carbon and Pre-Filter that captures 99. 7% of 0. 3 micron particles or larger on sleep mode, including pollen, dust, smoke, and dander. Plus, since it's three filtration technologies in one, you only have to worry about replacing one filter when the Filter Change Indicator is activated. Its small size means it easily fits into smaller spaces in your home. Use it in your bedroom to help create a peaceful sleeping environment with its whisper quiet operating level and a night light on/off switch. Or, set it near dog beds or litter boxes to help capture pet dander, hair and odors. It also works well in home offices, kids rooms, or dorm rooms.
