All Different Mask Testing Methods at Home


When you test filter materials at home, you may have different particles available to you to use or different equipment to detect the particles. Therefore one method may not suit all your needs. In this video I am going to show you 3 levels of particle filtering tests I have invented for your face masks or filters. These presentations are improved and updated a bit from the previous videos in which they were shown.

Many viewers commented on our previous video questioning the validity of higher pressure tests. We answered the questions and believe our test is a reasonable extrapolation. If your material led to a different conclusion, i.e. filter 1 is better than filter 2 under one pressure but the opposite is true under another pressure, please leave comments below because we have yet to find such a case.

In this video, we mention our previous video of “Easiest & Cheapest Way To Fix an Overheated Laptop In 30 seconds.” If your compressor gun is different than the one in the gas station and you are unable to connect to the bottle, I offered a simple solution in that video, here is the URL Clean laptop in 30 seconds

DIY face masks in 10 seconds & improve cheaper masks


What do you do if all face masks are sold out at every single store? After the coronavirus began spreading, there were soon no more face masks at any store. Restocking could take weeks. I will show you how to make your own DIY mask in 10 seconds.

What if the N95 masks are not available to you but you have a surgical masks? An N95 mask can filter at least 95% of airborne particles if you wear it correctly. A surgical mask does not effectively filter small particles from the air and does not prevent leakage around the edge of the mask when the user inhales. If you only have cheap masks, the biggest problem is that they may not fit well and there will be leakage around the edge of the mask. Since surgical masks are not designed to pass a fit test, I will show you how to make the mask fit if you don’t have access to an N95 mask.

We also proposed a couple of simple tests you can do to compare the effectiveness of different materials you have at home. We propose these minimal testing methods not because they are rigorous but because having an unrealistic sense of security by wearing a mask when it doesn’t fit well or being unaware of the level of effectiveness is also dangerous because you might then over-expose yourself to whatever it is you are trying to avoid. Be aware that having a false sense of security is dangerous. So even for a N95 mask, you need to wear it correctly and need to perform fit test.
