Bucky: There’s a difference between anecdotal evidence based on a sample of one and how well something actually works.

I have enjoyed the fact that I have not been sick a single day over the past 13 years I have had NPBI in my home, office and truck – not one single day. You people are way, way, way off base, underinformed and searching for a problem which does not exists – searching for a cause. NPBI is the best thing that has come along since the Polio vaccine in my estimation and GPS should be awarded the Nobel Prize – not kidding. NPBI is a replication and simple acceleration of nature’s natural cleansing process with nothing else added. Thus, If you have an issue with NPBI you have an issue with nature. Simple as that. There is nothing else on this planet that compares.

What I find objectionable is that the removal of contamination using this technology has not been scientifically tested in real world commercial sized (i.e. full scale) conditions. Most importantly, the various manufacturers and distributors that sell this sort of product has marketed the product in such a way to capture funding from organizations that could be used for implement equipment or operational changes that are demonstrated to reduce contamination in occupied spaces.

Cindi: Here’s an article I wrote about why you should avoid most electronic air cleaners. The ones to avoid are what’s referred to as additive air cleaners, those that add ions, oxidizing agents, or ozone.

The article isn’t really specific. Is it specifically putting them in air ducts that you find to be questionable? Or is it advocating the use of it as a single solution solve your indoor air quality issues, instead of recognizing the many other things you should be doing?

I fought hard against it and the engineer who was proposing it. He even said that he had used it to reduce OA in dozens of schools with no issues…the poor kids!

After that, I was always extremely suspicious of the claims. It seemed very quickly after that, most equipment suppliers in my area began representing an ionization company. Until ASHRAE publishes official guidance indicating the widespread use/adoption of the tech is warranted, I am staying away.
