Levoit Air Purifier PlasmaPro® 400S-P, Air Cleaner for Extra-Large Room, Smart Control

I've had this purifier for about a week now. It makes my room feel crisp and fresh by moving stagnant air around and replacing it with purified air. The best part of this purifier are all the smart functions. It connects to my phone so I can control it from anywhere in the world. And the PM reader is super useful. Definitely not a waste of money.

[This review was collected as part of a promotion.] I truly am impressed with the overall quality, design, durability, and functionality of this air purifier. Not only does it have a sleek and modern cylinder look, but it is also lightweight and easy to transport around the house. This air purifier is so quiet and easy to use. I was amazed by the ability of this purifier to detect dirty air. There is an air quality indicator ring that lights up different colors ( blue, green, yellow/orange, and red) when the air quality changes. I blew out a candle and within seconds the air purifier detected the change in air quality and the indicator light went from blue to yellow. It was only a matter of a few moments and the indicator was back to blue. I was blown away by how quickly this purifier eliminated the contaminated air and improved the air quality. The internal cleaner can sense the quality of air and will automatically adjust the fan speed as needed to improve the overall air quality and to clear the contamination quicker. I highly recommend this product because it works well and it will not disappoint.
