MIRA Safety - DotPro 330 - Industrial Grade Gas Mask Filter | A2 B2 E2 K2 HG P3 Filter Rating | Long Shelf Life | 40mm NATO Filter | Fits CBRN Gas Masks

Received product on time and exactly what I ordered.

Seems well made. Seals well. No odor. Haven't fully tested, but seems legit. No complaints.

Excellent product! I bought for a gift for my son in law. He loves it!

Wish they were $30 Otherwise welding and grinding on multiple metals, including commercial primer on some, doesn't smell. Also none of the accompanying symptoms of inhaling either of the fumes (dizziness, bone ache, sensation of weakness in the extremities) Don't overtighten, it's plastic housing, and it seals well. 10hr days will last you 2-3weaks before the paper pre filter plugs up. Good quality for a disposable filter

I use this filter for Volatile Organic Compounds. The filter work very well.

This filter does the job and it’s reliable and high quality. I use it for gaseous sprays and this will definitely protect me from harmful hazards.

These filters are the industry standard to the best of my knowledge. Do they protect against pretty much anything that you could dream of being exposed to with your lungs. Forty millimeter filter screws on to pretty much any standard military style and most civilian respirators, as well as PAPR FORCED AIR RESPIRATORS.

Best filter for the cost these are my go to, need to order more
