Air purifiers allow you to give your air the care it needs. From filtering out particulates to adding moisture to the air, the LG SIGNATURE air purifier can help improve your indoor environment so you can breathe easier (and more comfortably) any time of year. Discover just a few of the features that make our air purifiers the perfect addition to your home.

•        AAFA Certification: The best air purifier is one that effectively cleans the air so you can feel confident that your home is as safe and comfortable as possible. Which is why we're so proud that the LG SIGNATURE air purifier has been certified* by the Asthma and Allergy Foundation of America.
•        Integrated Watering System: Our air purifier's Watering Engine rotates at high speed—infusing the air with 18L of water per hour. Atomized water is then dispersed from the air purifier to create a comfortable humidity level.
•        Smart Indicator & Smart Lighting: With four stylish colors, the LG SIGNATURE air purifier lets you see, at a glance, what the airborne particulate level is in your home. 
•        UV LED & Smart Drying: The water in our air purifier's bucket is sterilized before sprayed—and when humidification stops, the purified airflow will automatically dry the filters to help prevent mold and bacteria from developing.
•        Smart Technology: Because even the best air purifier should be monitored from time to time, we've made the process easy. With SmartThinQTM technology, you can check your smart air purifier's status and even receive maintenance alerts using your phone. 
•        Inverter Motor: The LG SIGNATURE air purifier features 10 years of Inverter motor warranty—for long-lasting performance you can count on.
•        Stylish Design: With its clean lines and Rain View Window, the LG SIGNATURE air purifier will not only fit seamlessly into your space, but it delivers a visualization of the humidification process that's soothing to watch.
