If you have testing equipment, Zimi's valve leakage rate is far superior to its competitors.

We received feedback from a user on the Reddit forum that they felt the black breathing valve was leaking. We immediately sampled the relevant products and filmed some testing videos. Our sampling did not find any substandard valves. The GB2626 standard stipulates that the leakage of breathing valves should be ≤30ml/MIN. No substandard valves have been found in the past three years. Although Zimi made an incorrect choice of breathing valve in March 2023, resulting in a substandard valve, a new valve was updated in May 2023, and no substandard valves have been found since. Of course, our valves undergo high-pressure gas cleaning of the diaphragm surface before leaving the factory. If you find that the valve diaphragm is bent, please do not use it; simply open it and reinstall it.

  1. It changed the fixed way Zimi was worn, allowing users to switch between ear hooks or headbands at will.

  2. You won't see the cut in the ear loop, nor will the ear loop protrude, because it's hidden.

  3. I will launch new ear loops in various specifications, widths, materials, and colors, so everyone can choose freely.

  4. It will add an accessory to make it easier for everyone to use the third-generation strap. Any strap with a width of 13mm or less can be used in the next generation of products.

  5. It avoids problems such as ear loop damage and ear loop breakage caused by reverse stretching of the straps when wearing a head-mounted mask, which are problems caused by ultrasonic processing.

  6. The reverse tension strap is designed to pop out automatically without affecting the structure, and can be reused after self-installation.

  7. The length of the ear loop mask straps has been increased from 27cm to 29cm, and the length of the two straps of the headband mask has been increased to 45cm.

To be continued... We will share more about the third-generation frame upgrade, sealing ring upgrade, process upgrade, and performance upgrade later.
