Your cart is empty.A single-use respiratory device designed to achieve a very close fit. The ZYB -11- N95 Particulate Respirator Mask is a NOISH approved (NIOSH Approval Number: 84A-7877) respiratory protective device designed for secure facial fit and a very efficient 95% filtration rate of airborne particles. The 'N95' designation means that when subjected to careful testing, the respirator blocks at least 95 percent of very small (0.3 micron) test particles. This mask was also specifically designed to maximize protection while improving comfort through an adjustable nose clip. It also allows for easy breathing and speaking without comprising filtration effectiveness.

I bought these for an elderly relative out of state. They were a children's size. I lost over $50.

Great price for a 20 pack. The big box stores had 3 of these for $10 so I went for this one instead and am pleased. The youth group needs these for a service project where they will be doing home construction. The masks are substantial but comfortable.

I had been searching for N95s for most of 2020 to no avail. Finally in November I found these on Amazon. They were 50% less expensive at the time, but I would probably still buy them at their current price because of the superior protection that real N95s can provide compared to surgical/cloth masks. These are NIOSH approved masks, listed on the US CDC's website. Search key words "CDC ZYB-11" and it should be the first result. They feel and breathe very similarly to the 3M that I wore all year until these became available. I bought a few boxes and gave them out as gifts, and everyone agrees that they are much more effective than surgical or cloth masks.

I bought these masks for myself and employees who are working in a non-essential retail location. The masks are ok. Fit comfortably. They could be tighter (but I have a beard so without shaving I'll never have a proper fit.) I consider the 3M N95 brand to be gold standard and these are not on the same level in my opinion. Even if they are not true N95 (but I think they are) I feel they will work better than a loose cotton fabric mask in terms of COVID protection. Since these are being sold by Amazon without needing Authorization to buy them (like you need for 3M N95 masks) I think it is fair to say the medical community is not interested/using the ZY masks.When compared side by side to an old 3M 8511 N95 mask, the material on the ZY mask is much thinner. The ZY mask seems to have two layers; a very tightly spun melt blown layer on the inside and a smooth filter paper like layer on the outside. My 3M 8511 has the spun material on the outside and it is a much thicker layer. The inside of my 3M 8511 is very soft filter paper like layer and almost “cushiony” and also thicker.The ZY mask appears smaller but when I stack the 3M and ZY mask on top of each other the oval portion is nearly the same size, the ZY may be just slightly smaller. The ZY masks fits my large adult male face fine. It made an ok seal but not as good as the 3M seal. The 3M seems larger as it has a much bigger nose bridge section compared to the ZY.The ZY masks do say they are NIOSH approved (and I verified on the CDC website.) On the certificate of Qualification, they include in the box they say “Non medical N95 respirator mask”. The donning instruction sheet is not the same as the one linked on the CDC website but they do have the same images and language including grammar errors.Over all – I will use them to go to the grocery store and when inside the office with my coworkers for extended periods of time. I would not buy them if I had access to 3M products.

These filter out 95% or more of particles 0.3 microns or larger which is the standard for N95 masks. (*See update!)I like that it doesn't touch my mouth and nose. It also doesn't slip down under my nose. It has no smell.I wish they were cheaper but I'd rather spend more and get true N95. Beware of KN95 masks. They are supposed to be the Chinese made equivalent to N95 but the ones I've gotten do not meet the KN95 standard to filter 95% of 0.3 micron particles but instead only filter 95% of 2.5 micron particles. That's a big difference! Especially when you want to filter out the corona virus which is much smaller than 2.5 microns. So paying extra for a true N95 mask is worth it.I've wasted a lot of money on KN95 masks so getting true N95 masks is worth the extra cost. I have no idea why Amazon allows sellers to say "KN95 mask for sale" then describe it as filtering 95% of 2.5 micron particles. It's like saying "Silk shirt for sale" then describing it as being made of cotton. The lesson? Read the description and get masks that filter 95% of 0.3 microns.UPDATE: On the inside of the mask across the bridge of the nose, like the metal nose thing but inside, is a thin piece of foam. Very airy foam. It feels nice but my breath goes in and out through that foam which does not filter out anything! In cold weather I can see exhalation steam coming out of that gap unimpeded. I can feel cold air coming in past there when I inhale. It makes the mask virtually worthless. I ripped the foam out so it fits tight against my nose and no longer feel cold air rushing in via that spot. Now it Seals tight all the way around.

These mask are as close as I am going to get to the 3M mask that are so cherished in the medical community right now. I had some 3M respirator mask before CoVid (for woodworking,etc) I really can not tell you the difference between the two as far as quality. It has a decent seal around my face. The elastic is a looser than the others, but you can tie a knot to tighten. I am very happy because the price was reasonable and the quantity will help make the dollar stretch.11/27 update*** without tying a knot in elastic it is tight enough. I feel very safe in these. I wear them for an 8 hour work shift. When I take off mask you can see how well it seals around the face by the imprint it leaves around your face. Initially your face is hot under the mask due to your breath, but after a while you adjust to this. It is expected from these type of mask. Definitely a 5 star product
