HS-Zak MillerHS-Zak Miller Donut Negative Ion Mini Ionic Neck Air Cleaner Ionizer Purifiers Small Portable Wearable Personal Necklace Air Purifier,Pink

I bought this when I had Covid and was struggling with a cough and my breathing. I used this purifier every day along with an essential oil diffuser and really found it helped.Now I take it with me when I go out so that I have clean air everywhere I go. It's reassuring to have it in public places and helps with the hot summer air.The battery lasts for hours. I've used it for about 3 days in my car so far without charging. It is very practical - can fit easily in a handbag, lightweight around your neck, it can stand on your desk/table and also attaches to the air fan in the car.Would definitely recommend. I'm going to buy one each for my niece and nephew on their return to school.
