Review on Temtop Particle Detector Professional Accurate: Unmatched Precision in Measuring Airborne Particles by Wayne Girard

I am a doctor and I have a vacuum room in my practice. I use this unit to see how efficient exhaust fans and HEPA purifiers remove indoor air particles. I used a smoke pen and incense sticks to create the particles and then recorded the "cleansing" effect. This is a very useful device. When you look at the photos copied from the device. An illustration shows the effect of a HEPA air purifier and an exhaust fan. Another image shows the results with regular aeration particles for both produced by an incense stick for 10 seconds.
