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

This works so amazing, I pour resin and I can no do it year round indoors without issues. It has 3 modes of speed or air, so it doesnt fog up your glasses because of the air flow. It also has a super long battery life between charges which is awesome.

It really works!

Buy a Chinese made papr on eBay for $120. FAR superior to this piece of crap. I bought it hoping to solve a problem on the cheap, don’t make the same mistake. The Chinese papr is the way to go unless you have $1600 for a 3M system.

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.

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.

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.

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.

This device is very good

Works well for dust protection and positive pressure is also very useful for long time works

Small compact item, quality hepa filter, five included masks works well although, personally, I would prefer higher air volume output.

Cool idea. I used for my flight and it worked great. No sickness.

The fan is so weak that it’s basically useless. I threw it away. If you do buy it, don’t worry about replacement masks: the masks are ordinary ones with a round hole like a five-pence piece cut into them, into which the tube fits. One could surely improvise replacements.

This product is not designed for walking in the cold -20°C weather. My glasses keep fogging up. The mask does not seal properly on the face. The face mask should come with some sort of foam around the rim of the mask for proper sealing on the face Poor engineering.
