With its 360° air inlet, the Joy S is easy to place wherever you want. It operates efficiently in any space, even in rooms where an air purifier wouldn't fit. Ideal for compact areas like small bedrooms and apartments, the Joy S features Blueair's world-leading filter technology. It comes with a customizable fabric pre-filter and a combination particle and carbon filter. This advanced combination filter captures virtually all airborne particles: pollen, dust, pet dander, mold spores, allergens, viruses, and bacteria—along with 99% of all PM2.5 particles. The activated carbon even reduces smoke, odors, gases, and VOCs. It's easy to control and maintain. The super simple one-button control makes it easy to turn your air purifier on and off, as well as adjust the operating speed. Additionally, you'll receive notifications every six months (operating time) when it's time to replace the filter. The Joy S operates quietly and has very low energy consumption. This compact powerhouse ensures clean air from day one, and you'll enjoy low overall operating costs. The Joy S is an Energy Star-certified air purifier, using only half the energy of a small LED light.
