I'm a repeat customer and appreciate that Envirosafety carries these respirators. They're comfortable, breathable, fit well and are protective. I also like that they're available in boxes of 20. Ordering is easy and shipping is very quick. Customer Service is also great about giving status updates via email and voicemail. Excellent purchasing experience.

We had previously ordered the 3M 9010 masks, which have apparently been discontinued, and those worked pretty well for me (female, small face and tender ears).

Our most recent order were the Aura style, and this is truly comfortable for me to wear. The airspace inside this design is larger, which means my nose doesn't get as hot (which has always caused an immediate and continued drippy nose over my lifetime); and the mask top flap itself lies over my nose but the middle portion does not rub against and stimulate the tip of it (which also causes immediate and continued drippy nose).

Just this in itself is a big improvement, but in addition the foam strip along the top flap edge provides a complete air intake seal that was not complete (and a bit worrisome) with the previous design.

The 2 flaps + middle portion design is also much more comfortable in wearing for extended periods of time. (I'm a home health RN and have visits ranging in length from 1 to 12 hours, depending on the patient, and I have my mask on from getting out of my car before entering the home, to getting back into my car after leaving the home.)

I have much less of the drippy nose problem now, usually only briefly when I'm outside in the heat with it on until getting inside with cooler air, and as I am able to wear it with good fit with both of the elastics going around the back of my neck, it is comfortable to wear all day long.

This is the best one yet, and with the total of price of the case + tax and shipping, the cost per mask was $1.12, IIRC. That was the best price/mask and best protection I was able to find that fit within our budget.

5 stars across the board from me.

At last these are available again! I like the fold flat design and individual packaging, as they are easy to put in a pocket instead of having to carry one around when not needed. And they are soft against the face, unlike some that are made of a stiff material and are uncomfortable. These are also better than most at keeping my glasses from fogging. Great product!
