1 Formaldehyde is a substance so toxic that were it to make up just one part per billion of air itself, it would have exceeded the lifetime chronic exposure level, determined by the EPA, as set forth in its draft Toxicological Review of Formaldehyde Inhalation Assessment Report, of June 2010 Yet more than 6 ½ lbs of the material is manufactured each year for every man, woman and child on the planet and placed into thousands of products which off-gas toxic fumes into the air. So that almost every building has unsafe levels of formaldehyde. 1

4 And remove formaldehyde. How? When formaldehyde comes in contact with water it forms methylene glycol. waterwater it forms methylene glycol So if we had a wet scrubber within a building So if formaldehyde laden air passes through a wet scrubber formaldehyde is removed from the air. 4

5 Further, root microbes in a phytofilter then digest formaldehyde as proven In a $450,000 3 year study* where a phytofilter was installed in a building on the Syracuse Campus, and where it was found that “Seven (7) bacterial species from the botanical filter system using DNA sequencing were identified, including Arthrobacter aurescens TC1, Arthrobacter oxydans, Leifsonia xyli subsp. xyli str. CTCB07, Bacillus cereus, A. aurescens, Pseudomonas putida, and Bacillus spp [29] and Degradation of formaldehyde solution by individual species was conducted, with the result that the maximum reduction rate was 86.2% after 24 hours, by A. aurescens TC1 [29]. Therefore, as long as there are sufficient carbon sources (formaldehyde or VOCs) in the air passing through the bed, the microorganisms living in the sorbent bed will degrade them. Moreover, the microorganisms that are responsible for the degradation can quickly reactivate the carbon particle so that it need not be replaced, unlike the typical carbon filters used for air cleaning which need to be replaced every three-to-six months”. *New York Energy Research & Development Authority, Air Cleaning Technologies For Indoor Air Cleaning (ACT-IAQ): Growing Fresh and Clean Air, Final Report December 2010, Section 4-8
