Bwinmak Electric Portable Rechargeable Air Purifier Makes with Filter for Dust,Sanding,Polishing,Weeding,Protection Works

I usually wear a mask while mowing my lawn because of my allergies, however, from time to time I would remove it to get a breath of fresh air. I was able to wear this mask for the entire 2.5 hours, without removing it.

I have fragrance issues that close my throat. Going shopping or to meeting in closed rooms was out of the question. Cleaning, shampoo, hand soap or sanitizer, essential oils all were a problem. With this I can go. It doesn’t work though if someone is wearing something really strong or cigarettes are close, so 4 out of 5 stars. Great improvement in my life.

Item too heavy for mask so does not stay straight if it wasn't for that item would be great, can not recommend.

I used this for BM and BRC. If you kink the hose, then you limit the flow. That should be re-designed. I attached the filter assembly to a bike helmet via the included velcro. The velcro attachment to the filter assemble ripped off. That needs to be also fixed. Other than that it seemed to work. I needed the positive flow because passive respirators don't work or make a seal with someone who wears a beard. This is a good value compared to the alternatives.

Love it

I did not buy this for it's intended use. But I found my sand blasting hood would suffocate you without a fresh air supply. And this Item did the trick. Just hooked it to the inlet hose on the hood, and away I went.

This device is very good

These are amazing, with my allergies they have been so much help with mowing grass etc. my husband uses it in the hayfield
