TREND STE/LP/ML Air Stealth Lite Pro Mask

I have tried more than two dozen masks for pandemic protection and this is by far my favorite one. It has FFP3 / N99 level filtration, the straps and rubber frame are durable and easily provide an immediate perfect fit and tight seal. It is easy to breath in, and easy to speak in. It doesn’t muffle or distort your voice. My only issue with this mask is the amount of moisture that builds inside the mask after a couple hours of use. If you only need this mask for shopping or other short errands then it won’t be a problem, if you need this mask for a full shift at work I have made it a full 10 hours in one, no problem. If you are planning to wear one that long I suggest bringing a few to switch out every couple hours. I have been rotating these at work and they have lasted for months.

I bought this at the perfect time. I purchased this when it was only $3 each. I have about 50 in the basement now for future use. I use this primarily for woodworking and doing work around the house that has lot of dust. I have asthma and dust cause so much discomfort.These mask does an amazing job filtering dust, from all the normal woodworking operation such as table saw, miter saw, band saw, surface planer, jointer, wood turning, etc. All the heavy machines that cause a lot of fine dust in the air. I also use these mask when I am cleaning my pellet stove and cleaning out the filters on my dust collection. Needless to say that put out a lot of fine dust and I have no issue doing all this while wearing this mask.This is also very comfortable and light. I can wear these for a couple of hours and still not feel any type of pain or fatigue. Further more, breathing through them feels very easy, lots of air flow so I don't feel like I need to breath heavily. I usually wear them for 10 to 20 hours and move onto the next. The refill for these cost just as much as buying them whole, so these ones are the ones I got.

This is a good mask. I do a lot of work around my house. There is always sawdust, and dust from sanding around. I mean a masks are what they are. I don't think anyone enjoys wearing one, but when I have a lazy minute and I don't put this on when working, I totally feel the difference. I would purchase again.

This is a well-constructed mask. I use it in a woodshop that even though there is a good dust collection system the dust still is evident in the air. There were a couple of things I did not like about it. Firstly, as others have commented it has a vinegar smell to it (presuming that is coming from the rubber). Also, I have difficulty getting my safety glasses to seat properly on my nose.

This mask is very uncomfortably tight, even when loosened to maximum, and I am not a large person. There does not seem to be any way to replace the filtration without replacing essentially the entire mask except for the support structure. I will never buy another. Trend's half mask respirator is much more comfortable, with easily replaceable filters, better filtration, and costs only a little more. After replacing filters it is even more economical.
