3M Semi-Permanent Lens Protector FF-400-17, Pack of 5

I still have the first sheet on & its been a long time. I don't use it alot but it's a life saver. My uncle died of cancer he would say his working around fine powder was the cause. I know the film saves your vision & protects you & your mask from blind spots the scratches on the shield could receive.

I received genuine protectors. I put one on my respirator will little difficulty. However, keeping it and the respirator clean before putting the protector on without gloves is a pain for they are both dust & lint magnets!!!

Adheres to the mask very well, paint overspray cleans up easily. Everyone was complaining about the price, but I found it reasonable since they came as a multi pack.

These adhere all the way around the perimeter, sealing out any dust and crap and protecting the lens on your expensive mask. There is a cheaper one I tried out that only sticks on the left and right side. The dust got in and scratched my lens. Wish I kept using these.

Just wipe it clean with some alcohol after painting and it comes clean. These should last a very long time.

After 2 weeks of continuous use, sanding and painting the first one I put on and doesn't have a scratch. I've scrubbed with a rag primer particles off it two times too still no scratches. I haven't washed the mask with water yet, but I'd image if you didn't submerge, it would stay on. I took my time applying it making a tight seal along the adhesion strip. No dust particles have gotten behind it like others have said.

These fit my mask perfectly. I haven't had to change yet but I'm sure one I start spray painting I'll be glad I bought these.

Great idea for a great product

Super durable! I haven’t needed to replace the first protector yet in months of intermittent use.

Spray foam insulation had made a mess of the last one and the new shields are great. I just wish the choices were clearer shen shopping about how many are in a package so I know what I am buying.
