Uniair San Huei SH3500 NOISH N95 Mask Donning Instruction
- Hold the N95 mask/respirator in your hand with its nosepiece touching your fingertips, allowing the head straps to hang loosely.
- Cover your mouth and nose with the respirator, while retaining straps around the back of your hand. Pull the lower portion of the strap over your head and fit it around your neck.
- Stretch and pull the upper strap over your head, to the back of your head, above your ears.
- Using both hands, form the nosepiece around your nose. Adjust the tension in the upper and lower portions of the continuous loop head strap to obtain a positive face seal. For a tighter facial fit, increase tension by pulling the straps at either side of the buckle. For a looser fit, decrease the tension by pushing out the back of the buckle.
- To test fit of N95 mask: Cup both hands over the respirator and exhale sharply. If air flows around your nose, tighten the nosepiece. If air flows around the edges, repeat steps 3 and 4.
- Change the N95 mask immediately if breathing becomes difficult, if the respirator becomes damaged or distorted, or if a proper face fit can not be maintained. Careful observance of these instructions is an important step in safe respirator use.

I love this mask and have been ordering it many times with Instocking company. This mask doesn’t choke me over the head as other masks do. I like the strap design, which you can adjust to suit your head shape and is very friendly to people with big heads.
Jody C. –
Our colleagues at the nursing home love these masks. Individually packed, not too thick. Wearing it for a long time does not make it difficult to breathe.
Elizabeth P. –
Is it anti-fog?
[email protected] LLC –
It is fog-proof but needs to be completely sealed when you wear a mask. Please follow the instructions to wear and adjust the appropriate size.
PAUL H. –
Does this mask protect against Covid 19?
Emma B. –
We ordered a box of cup masks from Instocking. But I always feel uncomfortable after a long time. I complained to Instocking about this and asked if they could return it. After they got to know the situation, instead of just rejecting my appeal, they sent me an experience package to try it out. I’m glad I found this 3500 in the experience pack. It’s very comfortable. I ordered this mask for my family.

Reinhard Lueling –
Fit well and relatively comfortable
LAI Poh-Chin –
I function in education, and also needed something somewhat off my face with more protection as soon as masks went optional. I needed to turn the ear loopholes when for a far better fit, however overall these were wonderful as a glasses wearer with a smaller sized face!
Henning Thomas –

E.Mace –
