Rechargeable 4WDKING Electrical Air Purifier - Reusable and Portable Air Purification

Miriam: The media could not be loaded.  Later on I will submit a review of how it works. So far I like the quality.
I ordered for my daughter that has asthma and look forward to seeing how well it works for her since she is allergic to trees, grass, animal fur and dust so definitely will update in a few days.

CJ: I simply can't wear a mask. I just panic. However, a friend told me about this one so I bought it to give it a try. It's the best. The Pump is NOT loud as I read in some reviews. The hose it NOT flimsy as I read in another review. There ARE more than one grommet in the package, as a matter of fact there are 4. and there are plenty of masks too.
I'm very happy with this purchase and am so pleased I can wear it without panicking and feeling I have to GET IT OFF ME.
I played around with the different levels of air flow and really, level one is enough for me so the battery charge will last lots longer. A big than you to Aurora and a big than you to my friend for suggesting this.
It's a game changer for me.

George Thompson: I have been using the Aurora since Aug 2020. The battery didn't last a full day. I replaced it with a 3.7 volt lithium 18650 battery. The electronics went and replaced it with a toggle switch but I didn't get the air flow that I was used to. I found that the fan voltage was 8 volts. I added a second lithium 18650 3.7 volt battery in series and it works great! So far I have gotten three days use out of one set of batteries. I bought a second Aurora as a backup.
The product isn't perfect but it is much much better than anything else that I have seen. Any mask can be easily modified for use with the Aurora. I now have at least 6 to choose from. The two best are the O2 Canada and a 3M respirator.

Organic Alternative Farmer: I turned this on when I stepped out of the car at the airport. I took off the device for security and put it in a zip-lok that I brought just for this purpose. To do that, I disconnected the air tube at the device and tucked the end of the tube inside my mask which stayed on my face. Got through security, stopped and immediately put the device back on, left it on for the entire flight until I was inside my rental car at the other end. When I moved my mask aside to have a cup of coffee and a bite on the plane, I left the mask hanging on one ear so that clean air was still blowing. Do try it on at home and get your setup for how you are going to wear the device. I initially had it slung across my chest, fixed near the top. Once I was on the plane, I found that I was a lot more comfortable with the stretchy belt I'd chosen just wrapped around my middle, up high, like a high-waisted belt. That was super comfortable. Also, this will only run on high for 4-5 hours I believe it is, so I also bought a power brick, brought proper cable, and ran it off the power brick when its own power ran out. The seller has stated in Questions/Answers that it is ok to run it off a...

Heidi Baker: This device is spectacular! It has liberated me from that yucky, moist vapor that smothers when wearing a mask; but wear a mask I must these days. Oh well, that's OK.
This device not only keeps my glasses from fogging, it provides clean filtered air. While others suffer in their mask, I breath just fine. Nothing could have proofed the benefit of owning this device more than living in Chico during the 2020 California wildfires where the air was black and smelled of burning polyester couches except under the mask that provided cleaned, breathable, refreshing air. Once in a while I would have to remove my mask and one breath would leave me shocked and appalled that others around me were being subjected to breathing that horrible ash filled gunk. I apologize if this review sounds over the top, but it's not. I really can't find the words to describe the true relief this machine brought me during that time.

Elisa Palacios: Está muy padre este cubrebocas, si funciona y el ruido que hace el filtro no es tan fuerte aunque tiene 3 velocidades, estaría mas padre si la manguerita pudiera estar mas en medio porque cuando sale el aire lo sientes de un solo lado.

Scott Burgess: Caveats
Not designed for viral protection . Powered air creates positive pressure that amplifies all face masks fatal flaw, unfiltered exhalation leakage. So wearer gets gobs of filtered air , but increases exposure risk to those around you. We try to mitigate this and minimize leakage with simple modifications that will work to improve any mask.
Tighten mask to face with any mask frame, home made bracket frame made from 1/2" garden ties, and most efficent 8-10" cut off nylons panty hose used over entire mask.
Close any gaps 3/8 closed cell foam adhesive weather stripping applied to inside edge especially around nose piece.
We add standard mask exhaust valve with filter material fixed to inside of valve to provide lower bypass pressure. any mask with exhaust valve should have filter material fixed to inside. Otherwise it is just a virus concentrating and aiming device.

All brands claim h13 hepa filter. Some have niosh or china certification print on filters. We add layer of Merv 16 Filti face mask material from filti.com or any of electrostatic melt blown polypropelene available here on amazon on top of hepa filter. Setting aside filter...
