Easy to put on and use!

I need to wear a filtered breather when I do lapidary work. But the huge ones were very uncomfortable, fogged my glasses and had to be super tight to fit my small face. This fits my face perfect and doesn't fog my glasses so I can see what I am doing!

I ordered 3 types of masks, the 3m, Gerson(which is a 3m copy cat), and the GVS. I ordered medium and large on all 3 to see which fit the best. I really wanted to go with the 3m since it's the most known brand, you can put different types of filters which allows you to use for other jobs, but I did not like the head strap, it has these cheap plastic tabs, the face mask was a little bigger than the gvs, and I couldn't wear glasses with it. The gerson is pretty much the same design as the 3m, same strap, same everything. The GVS fit perfect, i love the strap it's so comfortable, doesn't block my safety glasses, and created a perfect seal even with my beard, I went with the S/M size, it just fits perfectly. I removed the filters, put some plastic to cover the holes, breathed in, and I was a complete seal, I covered the exhaust and breathed out, complete seal.... GVS for the win.... Like I said I really wanted 3m because of the versatility of filters, but, I haul the same material everyday, concrete powder, I'm in the cement plants and unless I change companies, this is the only filter I need, so I just went with GVS, besides no one in those plants are wearing masks, and I just look a lot less crazy with this GVS mask than walking around with those 2 big pink pancake filters on my face.... I also like that i could probably blow the dust off these filters, and reuse, I have an pressurized air hose on my truck, probably not recommended, but if the inside still looks white and clean, why not? I'll see if that works when the time comes...

This is not to be mistaken for an industrial or COVID-19 protection device. You pay a bit more than some for the design, but not more protection. You will still smell and possibly be subjected to some harmful fumes. It is not compatible with a line of varying filters from multiple brands. It is meant to protect against dust and dust alone. If it arrives dusty, as my first one did, it is used. Exchange it.

That said, it is a comfortable respirator. I purchased this to use in 3D printing. It is used alongside a filtered printer and air purifier as an added precaution for being exposed to particulates when removing prints. I can still smell the alcohol used for cleaning, despite being muted. This was found to be partially from a used mask and that you will need to upgrade the filters for some level of protection from fumes, albeit not much. I won't get into how I felt having realized my first mask was used, even if I make sure to clean such things before use.

For the price, it was a better deal than purchasing each part separately. It also seemed a lot more durable than the 3M knockoffs that are littered with reviews about breaking down. I wouldn't wear this one in a medical setting, especially without a filtered exhaust. I will, however, pick this over a cloth mask. You can't argue with the low profile for a little extra protection.

Unfortunately, the packaging arrives without any sort of seal. The first smelled like someone had already been using it in a chemical plant and appeared a bit dirty. The pop of what sounded like a failed seal was what really convinced me it was not storage in a dirty stockroom. This one was returned immediately. The next one arrived neatly packed and clean. It still had the smell of the materials used to make it, but not one of being soaked in ammonia.

The other big consideration is the proprietary filters. While I love that the intent was comfort, it only takes one low stock situation for prices to jump. Trusting that the filters will always be available and affordable is hard. This is where it pays for brands, such as 3M, to have so many knock-offs. Fortunately, Amazon has begun to stock the filters directly and there is a clone with filters that fit.

good ergonomics and comfort. price was a bit high at the time. Definitely my preferred mask when clearance and comfort are required
