(Human hair has a diameter of 100 microns.) We use a particle counter to measure the change in particle focus As a Outcome of the air air purifier runs for Quarter-hour On The very biggest velocity, After which at a decrease velocity. And since these run day and Evening time, we measure noise levels, in decibels, at every velocity, and calculate annual working prices for filter replacements and power use to run the machine 24 hours a day.
The three prime fashions in our air air purifier scores earn An excellent or Fantastic rating for particle discount at a low velocity whereas maintaining noise to a minimal. (All of them aced the extreme-velocity look at, as do many fashions.)
