Personal Air Purifier,Air Purifier Necklace Around The Neck,2021 Upgrade New Trave size Remove Pet Smell/OutDoor by IGOKOTI

Absolutely reduces allergens. Not sure if they keep you from being sick, but it definitely helps me when I’m cleaning my house and during pollen season. I wear one everywhere i go. I also mask up during flu season, but it seems to keep the bad germy air out of my way. I kinda wish it was a combined body cam/ air cleaner (lol), but I absolutely love this thing. I have a couple - charge does last for at least 30 hours, but it’s nice to have a backup when out. Also bought one for an allergic aunt and she says it helps her. Careful of the little ionizer - it does burn. But apart from accidentally getting it stuck in my shirt or brushing my arm, it’s fine. Believe the reviews who tell you not to touch it.

Works good in small space of 3 foot circumference and battery supposedly lasts up to 30 hours. Time will tell after 30 returns policy is finished and I will update if it’s bad or not. UPDATE 4/19/23 I reached to shipper about the 30 hours of run time and they sent me another one to replace the one I purchased because i reached out to them telling them I was only averaging 15 hours of battery usage. They said that I might have gotten a bad one. I have used the newer one they sent and that’s is lasting me over 20-25 hours of run time. So in a nutshell I am pleased with the item and the shipper for standing behind their product. Now the reason why I’m not getting the 30 hours is because I leave it in the vehicle and the temperature always changes from hot to cold and vice versa. The instructions do state not to keep in a certain temperature due to battery not going to work properly.

Works very good as a front yard Eye Catcher

I'm 66 working on 40. I've used this type of device for many decades in the manner described below. My old one was battery operated and I switched to USB charging for convenience. This air purifier works by pumping out small quantities of negative ions. I sleep with this on my nightstand every night about one foot away from my nose when I'm turned in that direction. I put it on a block of wood and spread the cloth necklace part out in a semi-circular pattern pressed against the wood, with the wick as the closest part to the bed. This is supposed to improve the flow of negative ions. All I know is that i seem to have more energy when I get up in the morning. When I want to sleep in more I don't turn it on that night or I will want to maybe wake up too early. It lasts three days and I keep track of that by moving a crystal to two different positions on the necklace on the second and third mornings. Then I charge it up for three more days. It works beautifully.

Not sure if it actually works, and it actually kind of burns if you wear it while wearing jewelry, or if it goes directly into nose.

The usb cable is a broken one and it cannot deliver any power to charge the device. I have to use my other cable to charge it. Even after hours of charging, the power of the device cannot last over 8 hours!!! I have bought 7 different small negative ion air purifiers and this is so far the worst!!

It's a must buy thing you would like to have when you are working in outdoor or indoor (such as warehouse, restaurant and so on). Easy to use and it is a small easy-carrying device ! you can bring it on travel trips and go to gyms. Highly recommend! Use it to clean crisp air scent occasionally. Been using personal air purifier during this pandemic , it would make you feeling got protected from it !

I tested this at home by putting vape smoke in a glass vase turned upside down on the counter. First without the purifier to see if the smoke would dissipate on its own and then with the purifier. The smoke did not go away at all without it. With the purifier the smoke was gone within about 15 seconds. I've purchase another brand from here (AirKitty) and the smoke took significantly longer to go away. Maybe a couple minutes or so. I recommend this brand. Reasonably priced and great as another layer of protection with your mask. Planning on buying 2 more for a trip to Europe in an effort to get as much protection as possible during the plane ride.
