I order not the first time, building dust does not pass until the filter is clogged with dust to breathe in the mask easily. Ordered 11.11, received 30. 11.

All is well, I advise you to Smolensk came in 14 days! Well, as for me very quickly)) all the goods would come quickly!)

Good value; Separately packaged in pairs with data sheet. Standard 3M filter connection.

It came quickly, the filter qualitatively filters the air. I take the first time

Look good, the packing is similar to the branded one. I think norms filters.
