I bought a fan powered respirator advertised on Facebook. Was it worth it?

Can you trust respirator ads on Facebook? Heck no, but I bought the PuriCurrent mini fan powered respirator anyway to find out if it's any good. Spoiler: It's relatively legit for a Facebook advertised respirator, but the fan doesn't make a lot of difference. The mask was ~50x cleaner of sub-micron particles inside, whether the fan was on or off. That is protective, but not as protective as I expect from a good regular elastomeric respirator like a 3M 6000 series with P100 filters, or from a NIOSH approved powered air purifying respirator (a PAPR). It's not surprising that the fan didn't make much difference, it only had about 12-17 liters per minute of airflow. A NIOSH approved tight fitting respirator has a required minium of 115 liters per minute of air flow. But there are some mini-PAPRs in this general class that do work better. More on those in future videos. The PuriCurrent is not NIOSH approved, so I don't recommend it for critical applications. It uses proprietary filters, so you would be out your investment in the mask if the manufacturer discontinues selling replacement filters. And the amount of carbon in the carbon filter is minimal, so they may not work for very long or be very efficient. --- Here's a non-affiliate link to the PuriCurrent mask if you are curious about it: https://www.amazon.com/dp/B0F2HLPYH4 --- Fit is individual. Your fit with this mask may be very different than mine. Check below to see how you can do a home fit test to make sure you are getting the best protection from your masks. --- I used an 8020A fit testing machine for the fit testing in the video. The fit testing machines sample ambient air through a tube and samples air inside the mask using a second tube. It compares the concentration of particles outside the mask to the concentration inside the mask, and gives a ratio of outside to inside called a "Fit Factor". The fit factor essentially tells you how much cleaner the air is inside the mask. A fit factor of 10 can be thought of as meaning that the air inside the mask is 10 times cleaner. You need a fit factor of 100 to pass a fit test in an N95 mask. The 8020, measures all the submicron particles that get inside the mask, including ones that went through the filter and the ones that bypassed the filter. --- You can do your own fit test at home using a nano mister and fit testing solution that you can taste if it gets in your mask. Fit Tests 4 All has a complete, reasonably priced kit they sell.
