LEVOIT Core Pet Care Air Purifier; Enjoy fresh air with your furry friends with the Levoit Core Pet Care Air Purifier. Its non-woven pre-filter captures furry friend-related airborne contaminants to help pet parents enjoy fresher air. The main filter captures at least 99.97% of airborne contaminants down to 0.3 microns in size. Plus, the activated carbon filter with ARC formula absorbs your furbaby’s odors and VOCs in the house for a healthier home. Making it even more efficient, you can activate the “Pet Lock” to prevent the settings from being changed. You’ll also enjoy how the VortexAir Technology creates a 360° airflow that spreads to cover most medium-sized rooms.
