Feel at ease in your home when you provide your little one's developing lungs and immune system with protection from potentially harmful particles in the air. The advanced four-stage filtration is intended to eliminate 99.97% of harmful airborne particles, volatile organic compounds (VOCs), bacteria, dust, pollen, pet dander, smoke and allergens. This purifier includes a negative ionizer that generates negative ions intended to reduce airborne particles without harmful ozone, while a 360º inlet/outlet projects purified air throughout your baby's nursery quickly and efficiently (up to 195 square feet). While on night-mode, the system is ultra-quiet and features a built-in nightlight, allowing the purifier to be used without disturbing your sleeping baby. Customize the atmosphere with three fan speeds and two nightlight modes.
