Professional use.
I bought expensive filters because in my shop I work with many types of plastics.
Specialized plastic welding, repair, and reconstruction shop.
When some of them smoke, the mask doesn't let anything through.
Also for painting.
Fits perfectly on the face.
Quick to put on and take off.
The shop that sent it to me was simply impeccable... fast, careful packaging and everything perfect.
I highly recommend it.

The best you can get in this price range!! Used in a cleaning workshop with heavy chemicals and nothing gets through.

I use it for resin, the filters that are specifically for chemicals do what they promise. The only thing is that I couldn't choose the mask size when ordering, there was no such option and I had to call them to ask them to send the medium.

The medium size fits well on a medium-normal male face. The fit is comfortable. The inhalation is also comfortable even under conditions of physical exertion and walking.

Quality mask with proper filters for amateur welding tasks. Fits comfortably under the welding helmet.

Very good mask. It is lightweight and, together with the filters, fits well without causing fatigue. Very easy to fasten and unfasten as well as to adjust to the face. The 6200 corresponds to a medium size and the 6300 to a large.

I bought it for non-professional use, mainly for when I use colors and it filtered perfectly. The application was very good. Depending on the use you want to make, you should get the right filter.

Excellent. I got it with a particle filter. It's worth taking some time to look at 3M's charts to find the filter that suits each job. It comes with a closing bag so that it doesn't constantly filter and reduce the lifespan, convenient.

Upon receiving the 3M 6200 mask, I noticed that its size (M) is too small for my face. I would have ordered the larger 3M 6300 size (L) if the product descriptions in the stores mentioned even the slightest hint that the mask is available in three sizes according to facial dimensions, and therefore one should be careful to make the right choice between the 6100 (S), 6200 (M), and 6300 (L) models. Even better, instead of advertising three different models of the same mask without mentioning its size anywhere, there should have been the option to choose the size in the main product so that buyers would not get confused.

Very good application, lightweight construction, good quality. The only downside is that when you sweat, it has a slight shift.

Very comfortable and high-quality mask. With the corresponding filter, you can protect yourself from simple dust and odors, from colors to chemicals, etc.
