Thinking About Upgrading Your Mask?

If you’re thinking about upgrading to a more effective face mask you might want to check out the videos available on YouTube from a guy named Aaron Collins (that’s the name of his channel too, Aaron Collins). My friend Jill sent me his link and told me he is her source for mask info, so that was good enough for me. Not knowing Jill, you might require more of a reference. What I learned from Aaron’s videos is that he is a mechanical engineer with a good deal of experience and interest in aerosol science and a collection of aerosol test equipment already in his basement. He is on a mission, through his testing, reviews and videos to get people into more effective masks. Here’s an article about him and what he’s doing that you might want to take a look at.

I also want to tell you about the mask that both Jill and I purchased thanks to his videos. What you see above and below is the BLUNA FACEFIT KF94 mask in size large from Korea. Mr. Collins is a big fan of the KF94s from Korea due to how well they perform in his own tests and due to the level of government (Korean) standards that masks made in Korea must adhere to.

He calls these masks “boat style”. The back of the mask when flat is shown above. Two flaps fold out to cover your nose and chin and there is a flat wire encased in the top flap that enables you to create a better fit around your nose. If you look at the photo at the top of this post you can see that the ear loops are adjustable by pulling on the little loops at the center of the side edges. It’s a very comfortable mask. I love how I now have a space between my lips, nose and mask in which to breathe. No more lipstick on my mask! And this mask does not collapse in on itself when you breathe in. That’s another thing Collins tests for the masks he reviews.

I followed the mask news this past week and was really surprised to see KF-94s left out of most of the articles I read. And I’m not sure about the emphasis on double masking. I tried that once in November when I was able to get a haircut right before salons in my area had to close again. I had some kind of surgical-looking mask I’d picked up at Target and topped that with my usual cloth mask. It was pretty clunky. I think it was about that time I started thinking I should look for a better solution. Don’t quote me but I think that Collins did address double masking in one of his videos and the result wasn’t positive. It was about face fit, the outer mask essentially pulling the inner one away from your face. Keep in mind that it’s not only filtration capability that makes masks effective, but how well they fit against your face.

I mean if you can procure a product at reasonable cost for your own use (or to donate) that was actually engineered to perform the task at hand to a very, very high level of efficiency, shouldn’t that be the recommendation? With a discount that was offered at the time, I purchased my masks for about $2 each at a site called My sense is that there is usually some kind of discount/promotion going on there. At the time I wasn’t sure how I could reuse the masks, but was delighted to find that information when I watched this video. Collins’ testing indicates that when used in a clean environment (i.e., not dusty like a construction zone) the masks remain effective for 30 to 40 hours of use. In that same video he shows how he rotates and stores his masks.

So grateful to Jill for sharing the Aaron Collins video tip with me and to Aaron Collins for taking on such an important project during this time. Stay healthy my friends. β™₯

    Thank you Colleen! Great post about these wonderful masks. I’m so glad you’re spreading the news about KF94’s and Aaron Collins. He is doing such a great service for people. I just bought some in black too. πŸ™‚
