How Easy Is It to Breathe Through These Materials?
To measure the breathability of each material, we recorded the fan power needed to blow a fixed amount of air through each material. You can think of this as the power your lungs need to blow through the material. Here’s how they scored.
Unfortunately, most materials that were the best at filtering particles were also the hardest to breathe through. That makes sense. A really dense, thick coffee filter can capture particles well, but it won’t let much air through.
The double layer 100% cotton T-shirt, bra pad, 70D nylon, paper hand drying towel, cotton bed sheet (120 thread) and denim (10oz) all fell between the breathability of the surgical mask and N95 mask.
Results: Smallpox-Sized Particles (0.3 microns)
For 0.3-micron particles, there was a much wider range in effectiveness. The N95 mask, HEPA filter, and surgical mask still did best, all capturing over 75%. However, the materials consistently captured fewer smaller particles than larger particles.
Among the household materials, the HERO coffee filter came up next in the list, capturing 62%. But only four other materials filtered more than 48%: the 40D nylon, CHEMEX coffee filter, the dish towel, and canvas.
Some materials were only slightly better than nothing. The bandana, neck warmer, scarves, cleaning cloths, and 100% cotton T-shirt all captured less than 10%.
