Helped my mom breath. She's a lung cancer survivor.

The apparatus works exactly as described. I prefer to use the second level of air flow because the battery will not last the longest on the third level of flow. The mini air filter that goes in the unit is genius and lasts. The air hose is designed to stay strait and not kink, kinking will greatly reduce air flow. Unit is included with a lanyard and a arm band with Velcro attachments. I prefer the arm band to keep the box as far away from the weld area as possible. If you plan on using this a whole ten hour shift you should consider buying two as the battery is not removable. A worthy and life saving product. FLUX CORE SMOKE WILL REDUCE THE TIME RATING OF EACH REPLACEABLE FILTER, REPLACE WHEN SEVERELY DISCOLORED OR AIR FLOW IS RESTRICTED. Play Safe. J.C.

The machine is great, it has worked wonders, and thankfully hasn't malfunctioned, my unit came sturdy and without error, I'd still be cautious, though. It doesn't warn you when it shuts off, I've personally never really had issues with the fan speed being too slow but again, mine came in flawless so it's probably an issue with different units, the hose does kink sometimes, but if you're gentle and mindful of it, you won't really run into too many issues. My current living situation isn't great and there's a lot of mold I can't reach so I've had to resort to buying different PAPR devices, and the HEPA filters that come with do actually work, good protection. I will say, the masks that come with the machine aren't that good, not only are they thin, they also fog glasses easily. I'd recommend just tracing the hole of those on a different mask and cutting that hole so you can attach the machine to it.

For the money it is great. I get allergy attacks that give me runny nose, sneezing and watering puffy eyes. Benadryl alone helps cease the misery 50% and combined with this mask 95%.. And I am not a robot or paid sheep. It really helps a lot!

It charged up and started fine. I was able to assemble it properly. The mask fit ok. And that is the end of what works on this product. The fan is tiny and provides very little in the way of air flow to the mask causing one to constantly over-breathe its capacity. The material on the hose is far too thin causing it to collapse, completely blocking any tiny air flow that does exist. This happens constantly no matter what position you try to use it in. The product might work if I sat perfectly still in a meditative position, minimizing my breathing, with the hose taped in a perfect position so that it won't collapse. But for real world use, this simply does not work. Cannot work. This is very disappointing because it would be relatively easy to design and build a product that works properly. The technology here is extremely simple; A battery powered fan, paper filter, hose and mask.
