M2 Mesh Air Filtration Face Protection Dust Mask with 99.9% Effective Carbon Filters for Woodworking, Construction, X-Large, Safety Green

Good fit and quality materials. Easy to use and hook and loop fasteners hold well. Great value. The seal seems to be firm and allows for easy breathing. A must have for good dust protection.

This is my 3rd RZ mask product and is almost as comfortable as the M2.5 , in size XL , but the fit is just as good . My first RZ product is a first generation neoprene (M1 ) , in size large , fits a little too snugly and needed the extension Velcro strip (included with all but M2.5 masks as they don't use Velcro ) to allow it to be all day comfortable. The mesh ones are a LOT cooler in the summer humidity of Virginia outdoors than neoprene but even their neoprene allows fresh air to touch your face where the inner filter isn't touching. This is where a good fit can be a good or bad thing. Good fit of the filter elements keeps more stuff out but that also includes a cool breeze and inhaled air when being very active . Things like running, biking, heavy lifting, etc cause me a slight discomfort as if I'm wearing an oxygen deprivation mask but the F3 or F2 filter elements really help. Is it as free breathing as no mask at all ? No but there's also never a sensation of a need to gasp for air after taking the mask off. The cheaper masks I've used that didn't fit well allowed more fresh air but because it was bypassing the filter to get in . The RZ F2 or F3 truly do reduce the resistance a great deal as I found out back in January when I was diagnosed with asthma but it turned out I had imminent heart failure and I was using the neoprene one at work to warm the air I was inhaling. The F1 (comes with all their masks ) left me gasping for air at times when moving very heavy objects at a fast pace at work but the F3 and F2 I bought reduced it a lot. After conquering the widow maker I'm ok with the F1 filters that came with my M2 and M2.5 but still enjoy the F3s I bought the most. The M2 doesn't feel like it's pulling down , like the neoprene one does after a while , and I believe it's because I got the right size. My measurements were right between L and XL so I erred on the side of XL this time vs L with the neoprene one . Filters from others won't fit right but of a great for isn't important they'll suffice in a pinch. I've tried the filters from other masks and they aren't as large plus the vent hole isn't exactly right on either side. The reason I prefer this brand over any others is the F2 and F3 filters. Other than that Base Camp brand mesh fits just as well as this one and is just as comfortable at a little better price but the RZ M2.5 with F3 filter wins hands down for my needs in a dusty, fast paced work environment.

I've been using the M2.5 mask for a while; it has two adjustable straps with micro fastex buckles for closing. The M2 mask has one large velcro strap across the back. It works great for my wife; she can strap it above her pony tail and it seals properly. For me though the strap slides down the back of my head, opening an air gap at the bottom of the mask. Same quality materials, same good charcoal filters for dust, odors. Decent mask, but I prefer the M2.5.

These masks work very well. A bit expensive for the masks and filters but I suppose they are worth it.

This RZ mask is now my favorite for dust control in a woodworking shop. It is comfortable, easy-on and off, and vents exhaled breath away from safety glasses. The high visibility color makes it easy to spot in the shop too. Couldn't be happier with it.

Great mask and comfortable design. I especially like the replacement filter inserts which are a snap to change. No more elastic around the ears to cause discomfort. Easy on and off.

Works well, fits well, easy to use

I like how easy the mask is to put on and off. Changing the filter needs a little more practice. The only problem is that the filters (F3) are sooooo darn expensive.

This is a good product . I recommend it.
