It sounds so nice and catchy.  Priobiotics for buildings.  We have written about it here are few times

• Probiotics for buildings in action? Interesting but can’t verify
• Probiotics for buildings: A potential future application of current work on microbes in buildings

Though I have not found any published science behind this movement there is more and more out there on it.  See for example:

• Pro-B Air – For Life: For a Cleaner Building Environment
• Better Air Uses Probiotics To Clean Air We Breathe | Environment …
• Could you clean your air with probiotics?

And other places.  The most recent I have seen is Better Air Cleans Sick Buildings With Probiotics | Green Prophet. which in addition to discussing the company “Better Air” also links to a Youtube video from the company:

I think all of these stories and blog posts are based in the end on some press releases from this one company but I would be interested to know if there are any other companies out there considered making probiotics for buildings. I would also be VERY interested to know if anyone has bought any of these “systems”.
