  Cut Grass Allergy Free
Reviewed by: Andy from Augusta, GA

I greatly appreciate the freedom using the 3M mask with 3M filters gives me when I cut grass. If I were to attempt cutting grass without a mask, I would not last 2 minutes without a lot of issues running nose, sneezing, congestion, etc.. With the mask, I am able to complete the yard work and move on in my day without issue.

Customer Q & A

Q1: We work in a heavy dust enviroment, and I need to know how many hrs this filter is rate for and also the micron size it filters

A: The filters for the 6291 mask will trap 99.97% of particles 0.3 microns or larger when fitted properly. As P100 rated filters, they effective for both oil based and non-oil based aerosolized particles of this size. Replacement times will vary pretty widely depending the conditions under which you use this mask. Most people typically see 50-60 hours of use before needing to replace the filters. For environments where you are dealing with a lot of particulate in the air like an industrial setting, you may need to replace the filter a little sooner.

Q2: I'd like to know how long these filters are effective?

A: They average about 60 hours of use. That's an estimate only. It's hard to give specific times since conditions of use, rate of respiration and factors like this will determine actual filter life, and those factors can vary widely from person to person. Now, if you do NOT needing it for highly polluted areas or work environments where particulate is especially problematic, most people can get more use with some people getting 80-100 hours or more of use out of the filter set. Typically, what you'll notice, in terms of needing to change them, is if it starts to feel harder to breathe through them. At that point, the filter media is pretty saturated with particulate, and they need to be replaced. If they're damaged they need to be replaced. This filter type is the one of the best in terms of having the broadest range of particles filters, including oil based aerosolized particulate, as well as the rate of filtration HEPA. Hope that helps!
