3M60928 CART-FILTER Organic Vapor/Acid Gas/P100 Pack of 2

I needed a filter to remove airborne mist droplets of many and various agricultural chemicals used in the broad acre spraying of crops using an open tractor and 40ft boom. As expected from a 3M product this filter removes any trace of spray mist (using a 3M full face mask in conjunction) with no smell or taste of chemical in the filtered air I breathe. There may be a cheaper filter from 3M that will do the job but I did have difficulty in judging from their huge range of filters, which was the best for my application. This one could be overkill!
