BASE CAMP M Plus Dust Mask, Breathable Reusable Face Mask with 6 Activated Carbon Filters for Woodworking Construction Mowing Grinding (Modern1)

Better fitting, functional mask. Because this has a neck strap, it holds the mask in place and helps with that annoying glass fogging that occurs with normal designs. My husband wears this when he is smoking meats or leaf blowing or doing dusty projects. With removable and replaceable filters, this mask is very very useful.

LOVE THIS MASK! This mask is the new version that replaces the one Basecamp sold prior to 2020. I had picked up the original style for mowing the yard (pollen allergies). It was perfect when the pandemic started. However soon after things escalated you could not longer get these masks nor the authentic basecamp filters. I had enough to make it through till this new style was available. I was so pleased with original mask that I bought this new version as soon as saw it was available. I have recommended it to many co-workers. I have to wear a mask at work when around others. I have worn it for hours on end and it remains comfortable the whole time and causes ZERO sore spots. I have even worn it to the junkyard for emergency parts pulling and it was not too hot. The adjustable bendable nose piece allows you to get a good seal. I have even perfected wearing glasses without fogging them up! :) This mask is breathable and does not trap alot of heat. Yes you still get a bit of humidity build up, but its a negligible. The vents do their job perfect. [I would recommend that if you are ever around anyone who is super high risk that you might get those cheap thin surgery masks to layer over the vents to offer them better protection, (like my 105 year old Grams)] This mask is a great fit and does not slide about like many of the other masks. It offers ear loops & an adjustable strap that goes around to the back of your head. This mask is unique in that way and allows a ton of adjustability. Once you get it fitted you do not have to fiddle with it at all! :)My only issue is that I have a small head. ( 6 & 3/4 hat size.) I wear youth hats. Any adjustable adult hat always covers my ears & the one size fits all falls off if I turn my head fast. LOL. So I made alterations to the mask to make it a wee bit smaller when I got it. Please check out my pictures to see how it did it. Before I would have the mask fitted to my face and wrap the head strap, but the Velcro would overlap so far it would not adhere. With my adjustment I get a perfect line up with the Velcro now. I am very pleased with the mask and highly recommend them. I bought one for me, my mother and 105 year old Grandmother. Everyone is super excited with their mask! Thank you BaseCamp!

the ear straps are a little big but overall It works. Purchased because of dog allergy. After some time, this doesn’t really work for the allergies. Bought for others in family, one works in construction and it helps with dust.

I looked at many of the dual port masks on Amazon; went over the reviews and the number of them. Most import. I looked at the MFG claims, 'English', timeliness of shipping, and response to an issue.All of these were excellent, either by review or personal experience.I also spent a great deal of time reviewing replacement filters. I found cheaper replacements, but none seemed to have the same quality.Of course both evaluations are purely subjective and 'marketing'. I do have >11 years in the field of Environmental, Health & Safety and another 20 years of Federal Service involving Product Assurance, Design ....So. without sophisticated laboratory equipment to evaluate a product, one 'rolls the dice, and takes a chance'. I chose this manufacturer.After using the product three times now for 2-4 hours continuously I can say that the fit and seal were very good; nose clearance to mask, very good; ease of taking a breath, while holding palms over 'exhaust' ports, excellent; ease of breathing out very good.I did find that I had to adjust the back strap 2-3 times to find the best position for ease of head movement. Even when loose the seal remained very good.One mask had a manufacturing problem when the package was opened. This is something that the Seamstress or Quality Assurance Inspection should have caught. I contacted the seller. In approximately 48 hours I had a replacement. This is excellent response and Turn-Around. To 'cut' the Mfg some slack, even in the very best "ISO-" Facilities errors do happen, though very rarely. Since I don't know what their Defect Rates are or Returns are, they get a PASS, and Excellent Customer Service.The only problem IS NOT PRODUCT related. If you place on going to any Medical Office or Facility. DO NOT WEAR it. As soon as I entered the building, while having my temperature scanned, I was instructed to remove it, because the exhaust air is not filtered. I said I was unable to get any seal with a disposal mask (blue type), any kind. The response was they cannot permit the use of any mask that has ports, even if the ports are "PM 2.5" filtered since they are not approved for medical use. So, I asked what about me breathing and exhaulting unfiltered air? They said they wete sorry. I asked if I could wear the Blue Mask under my mask???? No, I'm sorry. In the non-hospital complex, I saw all kinds of "filtering devices" being used, from "Scarf" types [filters ~57% of I/E air] to Hospital approved 'fitted masks [filters ~87% I/E air].So far, this type mask appears to be the best mask out there as long as: THE WEARER MUST BE/IS VIRUS/BACTERIA FREE TO USE AN UNFILTERED EXHAUST MASK for the welfare and safety of others.My bottom line - Great product so far. And, I will wear an "unfiltered N95 or N99 mask when going to any medical building of hospital. (Note: In one instance even that was not good enough. I had to throw this type mask fo a "blue mask". Their reason, (A valid one), they did not know where, how many times used, or 'cleanliness' of hands when touching it.This mask and THEIR filters get a 5 & 5.

If you have a big head this is not the mask for you. They need an XL size version. Seems like a well made product and functional, just too small if you've got a big head.

The mask fit comfortably and is easy to use. It provides superior protection and I had no issues with my glasses fogging, it is definitely worth the price
