Safe and effective air purification proven by over 15 years on the market and the most extensive safety and efficacy data in the industry.
At the Aerosol Research and Engineering Laboratories (ARE Labs), a U.S. laboratory specializing in the study of aerosolized microorganisms, Pyure conducted an evaluation of the kill rate on several pathogens, including viruses, bacteria and mold. The MDU/Rx™ device demonstrated a kill rate of between 99.9% and 99.99% within an hour.

Two viruses were selected to evaluate performance against RNA and DNA based viruses:
Two vegetative bacteria were selected as simulants for a broad range of pathogenic bacteria:
One species of black mold
Comparative Biosciences, Inc. in compliance with the US Food and Drug Administration GLP regulations (21 CFR Part 58), conducted a 13-week toxicology study on the effects of elevated Pyure output levels on a statistically significant population of rats. Rat exposure levels were 2 to 3 times higher than the maximum levels recommended by Pyure. The results showed no adverse effects on treated animals vs. control animals after continuous exposure for 13 weeks, neither at the gross or cellular level.
This toxicology study, along with the mechanism of action and pathogen destruction studies, were submitted to the FDA as part of the 510k registration and listing for the MDU/Rx™ unit. As part of the FDA submission, a review of NIH, CDC and other relevant government databases was conducted. The review did not reveal any data or evidence that natural natural or artificial hydroxyls are in any way toxic to humans, animals or plants.
A study conducted at the Lovelace Respiratory and Research Institute (LRRI), in an ultra-clean environmental chamber demonstrated that:
These results were subsequently published in a peer reviewed scientific journal. (David R. Crosley, Connie J. Araps, Melanie Doyle-Eisele & Jacob D. McDonald (2017) Gas-phase photolytic production of hydroxyl radicals in an ultraviolet purifier for air and surfaces, Journal of the Air & Waste Management Association, 67:2, 231-240, DOI: 10.1080/10962247.2016.1229236).
A study of the chemistry resulting from hydroxyl decomposition of VOC was conducted at Columbia Analytical Group. The results showed that ambient VOC were rapidly decomposed and that the steady state amounts of intermediate organic decomposition products, including aldehydes, ketones and alcohols did not increase above ambient levels in the treated space. Pyure Technology decomposes the VOC initially present and then decomposes the VOC formed as oxidation by-products, leaving behind a low, steady state concentration of VOC like that found outdoors.
