Rechargeable Electric Air Purifying Respirator, 2 Speeds Fan Modes Anti-Fog Air Purifier with Replaceable HEPA Filter for Outdoor Sports Housework

UPDATE*The mask suddenly started making a loud buzzing noise when in operation. It's only been used 8 times for less than 2 hours each time. I've only had to charge it once because it's written so infrequently. I'm very disappointed that it broke so easily. I've requested a replacement and the seller says they will send another body.Worth every penny! I have COPD and breathing with any other mask is laborious. This mask solves that problem nicely. The HEPA filter really works well! I pumped gasoline while wearing the mask and couldn't smell the fumes through it! It's very quiet and unlike a lot of items I've ordered from China, this one is very precise and well made. Its lightweight and the silicone straps have different ways you can wear them for a very secure fit. It comes with an ear saver, one extra filter and is charged. I recharged it just to top it up, but this seems like it would last for several hours before needing a recharge. It comes with a carrying case that fits the mask perfectly too. I absolutely recommend it!

Very pleased with this electric mask, I've been buying more. Where ever I can find them. great seller btw!

I'm on my 3rd day using this electronic mask while traveling on the NYC train sytem.its a comforatble feel, powerful fan keeps the cool air consistent.so far love the product.

I never thought I'd receive this product as they say It was delivered on June 1, when in fact, it didn't get to my residence until the end of July.Having said that, the battery used to last (low setting) for a full 8 hour shift. 2.5 solid weeks later, that battery lasts 5 hours on the same setting. Its run 40+ hours a week. No complaints... Perhaps different color specs.. Black of course... Or red perhaps.

I'd suggest you hold off buying until this product is improved. Problems:1. Air leaks on both sides of the nose, making the mask useless for American faces -- it was probably designed for Asian faces with different contours.2. The directions are not in English.3. In order to return it, you must pay return postage to China and then they reimburse you.4. The customer service phone number listed for the supplier is inoperative.

It too over a month to arrive from China and instructions are in Chinese only. It is a plastic based rigid mask. It is a novel concept built with quality materials but outside air leaks between the nose and the cheeks gap. It has a fan that brings fresh air in so it feels better to breathe than just a regular mask but I am not sure if that will force more virus inside. It has silicone flaps on bottom holes with the objective of allowing exhaling air out easier but it really doesn't work. It came with an extra filter and I wouldn't know where to get quick replacements. It has a chemical smell that may go away. I may still use it in an airplane together with something else if the toxic smell dissipates.

Once you figure out the non-english instructions for straps (not to hard if you look at the tiny picture)Battery on low lasts well over 8hr.The clear plastic cover over the colored cover was great. I draw with dry erase markers and then cover with the clear. (A bit tricky to separate the two)

This is an engineering marvel if you ask me. Product was delivered on time on both occasions. I've had this mask for over a month now and decided to buy another as backup. It's comfortable, lightweight, yet it provides clean filtered air for a long duration of time while helping to keep my face cool. On LO fan speed I was able get about 8-9 hours usage before USB recharge. On HI fan speed about 6 hours usage, respectively. Will buy from seller again if necessary.
