AirTamer A315 Portable Negative Ion Air Purifier - Rechargeable Personal Air Cleaner with Travel Case | Proven Performance for Home, Office & Travel | Black with Black Leather Case

HIGHLY RECOMMEND THIS AIRTAMER 315!!! IT WORKS! KEPT ME SAFE!!!!So I bought this for a trip that required me to fly on an airplane. My biggest concern was Covid. Ever since the mask mandate was dropped I didn’t know what I could do to ensure my safety. So after reading a lot of reviews on Amazon and other reviews outside of amazon for this airtamer 315, I was convinced to give it a try.It’s main function is to basically give you a bubble space of 3 feet! It repels all unwanted dust, pollen, and germs.I wore it on a 6 hour flight and wore my mask too. I took off my mask to eat and sat next to people who were not wearing masks. We had conversations while I we ate and I didn’t get sick on flight. The flight was fully packed.Also, on my trip I wore it every time I stepped out of the house to go shopping and attended several large arena events, I didn’t get sick.I went to several restaurants where the servers were within 2 feet of my face and still didn’t get sick. I’m usually highly susceptible to colds because of my allergies, but the airtamer 315 kept me safe.In my opinion, I feel it works and does what it says it does. It also helped with my allergies too, since there was a lot of pollen in the air.The lights on the back helps me to know that the battery is charged. (This is why I chose this version.) There are four indicators. One light is steady to indicate it’s on and other three lights flash indicating a full charge. Total of four lights on the back side. There is also a clip on the front if you want to clip it to your shirt. I didn’t clip it. I let it hang on my neck. I was concerned it might give me a headache to wear something on my neck for hours, but it is so lightweight, couldn’t even tell I was wearing it!When charging the red light indicator is bright red and when it’s completely charged the red light is dim. The red light does not turn off. It seems to have a long charge hold. I used it for 10 hours straight for two days without charging and the green lights were still flashing full charge.I have only been using it less than a month, for approximately three weeks, so far so good!
