I bought one of the Dylos monitors several months ago and I was initially quite impressed. I have the more advanced, 0.5 micron model, and it reported count readings that seemed to correlate with time of day (lower reading at night) and activity (e.g. higher reading when I am dusting) However, I was not as impressed after it started to report readings that were inexplicable. For example, after a while, the reading seem to rest on a plateau of about 2200 (which signified bad air quality), whereas before it should normally read 700. I taped a piece filter paper to cover the ingress and the reading will drop to 1700. So I called up Dylos customer and technical support, who were very friendly and helpful. However, the answers I got from them were not entirely encouraging. First, the monitor had no calibrating function. So, if you suspect the reading is too high (as in my case) or too low, you are just left wondering; and of course, once you think a test or measuring tool is suspect, you don't trust/use it! Second, both the ingress and egress of the monitor has no wire gauze to protect insects from getting inside. This is not good, because if an insect got inside and contaminated the lens, the readings would be completely meaningless. Third, worse yet, you are not supposed to open up the monitor (it will void the warranty; laser might injure your eye if you are not careful) to do any cleaning. So, if, over time, cooking grease vapor, say, condensed on the surface of the lens, the accuracy of the reading would be called into question, and you cannot do any meaningful cleaning. Dylos technical support was kind enough to check and service the monitor for me (even though I admitted to having opened the unit), but the monitor still does not work right.So, as much as I appreciate the good folks at Dylos, who really tried to help me, I just do not find this monitor a reliable tool, due to the design flaws I outlined above, which I hope they would address in a subsequent version. I hope your experience is better.

I bought the .5 micron model. The reason I bought one of these is to test the exhaust from different HEPA vacuum sweepers I have. All I wanted to know is what works and what doesn't... meaning what vacuum sweepers put out readings of "0" particles down to 2.5 microns on that scale reading and "0" particles down to .5 microns on that scale reading in the vacuum's exhaust air. I simply put the Dylos near the exhaust port on the vac and waited for the results.My lead and asbestos safe vacuums are easily confirmed to the "0" readings as they should be, where other HEPA vacs I own were confirmed to blow all kinds of potentially toxic dust out their exhaust ports even though they were "HEPA" vacs. And yes, we have since trashed every HEPA vac that did not blow clean air. Some of the "hepa" vacs were blowing out as much as a staggering 670,000 particles per hepa-filtered cubic foot of air... it was really eye-opening.The Dylos told us everything we needed at a very reasonable price and I feel it is saving our lungs on the job site. This may not be the manufacturer's intended use for this product, but it works.

The day after I got this meter, I accidentally burnt some food, in quantity corresponding to about 1/4 slice of bread. I opened windows on opposite sides of the house, put a box fan in one of the windows, and turned on the central A/C fan to keep the house air well mixed. Then I took a reading with this meter every 5 minutes for 70 minutes. The result was a perfect exponential decay, as expected from the differential equation. I'm sold on this thing. If it last at least 5 years, I'll be a happy camper. Now I have a reliable way to tell when to run outdoors and when to run indoors. Currently, the outdoor PM2.5 is about three times higher than in my house. So I'll be running indoors this morning.
