Trying the Particle Counter

A project log for Household Electrically Enhanced Wet Scrubber

A household air purification unit for kitchens, labs, & smokers used to scrub fine particulates and VOC's out of the air.

After my spell with acute bronchitis, I was even more paranoid finding out the performance of my invention. I purchased a particle counter, a Dylos 1100 Pro air quality monitor for a couple hundred dollars. Not cheap. This device is a consumer grade laser based particle counter that can detect particles down to the 0.5um range and 2.5um on the high end. I was hoping to use it to test the performance of my wet scrubber. I thought I would try the device with just the wet scrubber, minus any electrical enhancement stages.

I placed the particle counter in a small room in my house and got some baseline readings.

The initial reading was about 500 particles/0.01 cubic feet above 0.5um and about 80 particles/0.01 cubic feet above 2.5um.

I placed the wet scrubber in the room and ran it for 30 minutes. When I came back, I was shocked! The counts more than tripled! Ha! This machine produced more particles than filtered??? The readings when to about 1800 and 300 for the 0.5um and 2.5um particles respectively --HA!
It occurred to me that what I was reading was water vapor that was introduced by the wet scrubber's water pulverizing action. I confirmed this by placing an ultrasonic mister near the particle counter and sure enough the particle count skyrocketed. How then do I get an accurate reading of my wet scrubber performance without spending an even larger fortune? Perhaps I can run the wet scrubber and set this number as a baseline count to be subtracted later???
