    I just found that the Lawrence-Berkeley Lab has a summary of their testing on their website.

    I went and read the abstract for the research study (I’m not willing to pay Willey the fee to read the entire report). To me the most interesting part was that 4 of the 7 consumer products did very well and that the research grade monitors (I assume the products referred to in this article as costing thousands of dollars) missed events involving particles less than 0.3 um along with the 7 consumer grade devices. My take-away from the abstract is that the consumer products seem to be doing very well for what they are and what they cost. Since even PM10 is essentially invisible indoors, I can completely understand why someone would want one of these if they lived in an area with some sort of recurrent pollution problems or they had specific health issues.
    There is always room for improvement, but it sounds like some legitimate products are currently available. Is there a reason that Fair Warning isn’t naming all the products tested?
