Our AliExpress opening is restricted, and we will consult Amazon next. If it is also restricted, we will build our own website for sales. At present, I will update the purchase method of SUPERBUY as a transition.

I like to study masks. I have published a lot of research content related to masks on Zhihu. If you are interested, you can take a look. I am considering posting these research contents on reddit.

Once upon a time, masks of this color represented safety, and customers required this color. Now, as demand declines, it is no longer a popular color. This year, 3M took the initiative to apply for the cancellation of the medical device registration certificate of 9132 in China.

Am I salting the vibes wearing a respirator to get my labs done? I have to have them done at least once a year so insurance will cover my diabetes meds, and since the doctor dropped masking it's up to me to protect myself as best as I can 😷👍 #YallMasking #SaltTheVibes

Vor Kurzem erreichte mich ein nachträgliches Überraschungsgeschenk zu meinem Geburtstag. Es waren drei neuartige KN95/KN100 Masken aus China vom Entwickler @zhouliang_mask . Herzlichen Dank! 🤗 Diese Maske ist mir auf Twitter schon einige Male begegnet. Von außen wirkt sie (1/18)

For ZIMI masks, the bracket + filter is the most cost-effective way to use it, so we are looking for people who can assemble the mask the fastest. When I thought my 4.65 seconds was fast, 2.86 seconds came. Records should be broken constantly.

Today, ONE-F has started selling on Taobao. This means that each model of ZIMI mask can purchase the corresponding filter version (except for the models that are about to be discontinued). The next update is 9233-03 and the black version 9233F.

I really like @NukitToBeSure 's point of view. The integrity of the manufacturer is very important. Any product has its value. It is very important to be realistic. In the mask industry, there are many different standards and different testing methods. Everyone promotes that masks

In my humble opinion, I would like to offer a few ideas for NIOSH 42CRF PART84: 1) add a fit test, 2) add a mask dead space test (carbon dioxide residue), and 3) lower the breathing resistance limit. In addition, there are also excellent earloop masks in the world, so don't

[9/9] The key take away – we have the filter technology. So it’s all about fit,fit, fit!. We also need to include fit requirements for N95’s. They are not one-size fit all, @NIOSH we need either better fitting N95’s or more access to fit testing!

He was targeting Zimi on purpose, out of jealousy and selfishness, the adjustable ear straps, the modifiable frame, destroyed his game specifications, so Zimi was a thorn in his side. In this case, we broke his game rules.

Yes, facial hair will affect the fit according to NIOSH guidelines, but cloth and silicone have different tolerances for facial hair. If you have a test device, you will notice the difference.

@etativel_ I pass a bitter qualitative fit test even with the 🧔🏻! The head strap style is important in the case. One can still get good fit with a clean shave and their ear loop models, though. There was even light pressure all round from the frame. I’ve worn for ~2 hours very comfortably.

This is a valveless mask, earloop/neck-worn, not headloop. The speaking test uses the same content read aloud, and the data is normal. In the water immersion test, water cannot penetrate into the meltblown interior to take away the deep charge, so this test does not affect the

9233 is a medium-sized mask for adults that we launched last year. 9233 is a KN100 grade mask. Currently, only the head-mounted version does not contain a breathing valve. There are three packaging specifications, namely 10 masks, 1 mask, and 10 filter cartridges.

@noms780 asked me the other day: why I prefer wearing Akkair over Zimi? (Akkair is an associated brand of Zimi, equivalent to Zimi 9541, with more choices of colors, ie. more "fashionable", but a bit more expensive) Well the answer is simple: for better looks!😎

Please do not discuss the fact that the ear straps of the 3M 8233 are not installed on the mask. This is its design and does not affect the fact that it is a great mask.

Before using a mask with a breathing valve, you need to check whether the diaphragm and the base fit well.

Different mask standards, the same testing agency, the same testers, the test results are very different. Because these are two different standards, the test methods are different. The following data comes from a third-party testing agency, which tested according to the standard

What's even more ridiculous is that they actually suggested that we buy fake certification. It is conceivable that the only company in the world that only develops frame masks and whose team has been researching frame masks for 8 years has suffered such a fate. However, we will

ZIMI masks mainly comply with the GB2626 standard and are all produced in Shanghai, China. Then, we were restricted by AliExpress. We are GB2626 masks and did not claim that we meet NIOSH and EN149 certifications, but we are still required to show NIOSH and EN149 certifications
