ISTOK-400 RU-60m

There is no foreign smell from the product.
Well fixed and close to the head.
I tried to inhale tobacco smoke through this respirator, the smell of smoke was slightly felt. For dust, that's it.

It would be nice if the respirator was supplied in a pouch-bag or in a case, so that it is convenient to store the respirator with spare filters.

It fits even better than a similar 3M mask, the elastic bands are wider and better, the fit is excellent, it rubs (rubber) a little. The smell of solvents knocks off, I did not notice vapor poisoning.

There is no use for a couple of weeks.

Filters are cheap relative to 3M.

Convenient fixation system on the face, fits well to the face, although not completely sealed. There is no smell from the respirator itself. Filters fit securely. When working with glasses, the latter do not fog up at all, which was one of the main requirements for a respirator.

I used this respirator when chipping the walls with a grinder, the dust was unmeasured. It copes well with an average amount of dust, but at a high concentration it starts to pass inside. You need to understand the volumes for which the respirator is designed and buy appropriate protection for more serious work. When sanding walls, the respirator coped with its task perfectly.

performs its function,
fits as well as 3M
fasteners do not rub

the mounts seem to be unreliable, but compared to 3M they do not rub and can be changed.
It smells a little paint during operation, but this is already the case in filters, you can put filters P3, cost around 1000 rubles

Compared to 3M, the complete analog has its pros and cons.

Who writes about the stink is bled

smells like rubber, after the first application there is almost no smell.

3M stinks no better - some kind of sourness, there is also a smack after it, and now it just does not smell.

Acceptable price
Copes with its task

With prolonged work, the face fogs up
Bad rubber smell

I read several reviews that it does not fit well to the face, I thought about taking it or not, I decided to take it. I was not disappointed.

For those who have a poor fit to the face, I can advise you to try to lower the respirator down from the bridge of the nose to the chin. So the adhering to the face will be as effective as possible. In other words, don't try to pull it right under your eyes. Although the rubber stinks, it is fixed well and follows the contours of the face.

I recommend this product for purchase.
