This Air Purifer by isYoung is really been a blessing to me in so many areas. I have terrible hayfever and this air purifer has really helped. Not only did it help with my hayfever, but I have a camper I go to on the weekends and it has a musty smell in it from being shut up during the weekdays. I put the air purifer in it and musty smell gone. It is really amazing device.
It is small enough, 4 1/2 inches tall, that i is so portable. Great for your car, the smelly bathroom, your closet to keep your clothes smelling fresh, anywhere that you want to have clean air.
It uses the ozone principle to sterilize, remove the smell and deodorize the indoor air. It has 2 different modes, the blue light comes on at the top and it purifies for a limited amount of time, then goes into stand by mode, press it again and the green light comes on for the boost mode. There is a place at the back that is for the USB cable to charge it. The USB cable is provided.
It states in the user manual that it indicates that the enviromental protection period is 10 years. That is much longer than any other air purifier I have seen.
I do plan on purchasing a few more of these, keep one in my car at all times and I think this will make a terrific gift for anyone.
