The quality exceeds all expectations, I recommend to buy.
I will add a review: I checked it out at work, everything seems to be in working order, and the test with paint and building dust was a huge success! There's a risk of getting claustrophobic in there. Generally speaking, I would advise purchasing.
Pros
Excellent mask made of silicone; it conforms exceptionally well to the shape of the wearer's face; the adjustment mechanisms function flawlessly
Additionally, the filter pieces have a high level of craftsmanship.
Even though I haven't put it through its paces at the office just yet, I have full faith that it will provide excellent respiratory protection.
