BROAD AirPro Mask Electrical Air Purifying Respirator (Standard Edition)

I continue to be cautious about wearing masks in risky situations because my long covid leaves me vulnerable to a poor outcome if I am reinfected. But wearing good masks for an extended time is stressful. This mask draws air in thru a n95 filter and then delivers it via a soft silicone tube to an n95 mask. So while wearing it you get a constant supply of 'clean air' that prevents you breathing in contaminated air around the mask. Additionally the air in the mask stays wonderfully cool, making it so much more comfortable to wear. I have used it on long flights for 11 hours and was really relieved by how comfortable it was and how safe I felt! The mask itself is an n95 and will provide as much protection to those around you as a typical n95mask. Given the imperfect fit of all of these disposable masks the protection is more in the limited distance exhaled droplets spread than in much actual filtering. The unit is very quiet. You hardly can hear it. You can order replacement filters for the unit as well. I have found that I can drop the unit, on its lanyard, under a sweater or jacket with just a length of the hose coming up to the mask so it doesn't look to obtrusive. One last thing. The fan works while it is being charged, so in the car or on flights or with a backup battery such as you might use for a phone, you can charge it while using it. Anyways, highly recommended! If you are also having to be extra careful this will be a game changer!

This product is very good and No suffocation in this Mask, feeling well

Best thing EVER! I have vocal paralysis after a thyroidectomy, so breathing is difficult enough without masks. This gives 3 levels of air, but remember it is taking air from outside of the unit. If you are outside in the heat, you get that same hot air. If you are in the ac, you get the cool ac air. It feels like you aren't even wearing a mask inside the ac. I am a service person in and out of houses all day. I have been wearing this for several days now and the battery is still fully charged running mostly on the 2and level. I am carrying a beefy portable charger in case the battery dies in the middle of a job, but I do not see my ever needed it. A night time charge will eventually be enough as I will have ample warning of battery depletion. I often get strange looks and my husband says it looks extreme against my black work shirt, but I know people are actually wondering where they can get one. I also feel like if a customer isn't wearing a mask it is protecting me from them as well since it not only has the N95, but the Hepa filter as well. Probably a false hope, but probably a better level of protection than a homemade mask that gets tugged on all day. The fit is perfect, air placement perfect, air box is not so heavy it is even noticeable on a lanyard. This mask is much more comfortable than any N95 mask I have ever worn, so I doubt I will be cutting my own 1/2" hole in anything bought locally. They seriously got this 100% right the first time. I am thinking I should buy an extra one just in case this one breaks or the prices get ridiculous because the secret gets out about how wonderful these things are. The only thing that could make it better is being made in the USA

Pollution free breathing.

I have now bought several of these and have provided to friends and family. I used one on my first post pandemic flight myself and felt more comfortable that I was protected. I believe that after making minor modifications, the unit provides better filtration than an N95 mask alone because the positive pressure reduces the amount of leakage around the mask when you inhale. It also just feels more comfortable with the provided airflow. Since I am an engineer who was recently designing similar larger devices, I tested this filter with a laser particle counter looking for 0.3 micron particle size. I found that some air could bypass the filter around various leak paths. Covering the usb charge port during use was an improvement but finally I found that I could solve the issue with silicone caulk applied around the pcb inside under the filter. I have modified several this way now and confirmed performance. Prior to that modification, the filter performance was worse at high speed than low speed and sometimes marginally N95 caliber. After the modification, I get very low particle concentration around 200 particles per cubic foot in a room with background count around 500,000 particles per cubic foot. Prior to the change I was counting around 6000 - 8000 particles per cubic foot. So the bottom line: It IS more protective than an N95 filter and more comfortable. Its true that the tubing can kink and I suppose it could tear. So far I have not had those issues. I used a 3/8" leather punch to make more masks for it and found a different style mask that worked a little better for me. I have also measured the airflow rate with a hot wire anemometer and though there is some measurement uncertainty, I can affirm that its in the range of 2.5 - 3.0 CFM on the high setting.
