Yes! In a clinical report from the Journal of Clinical Sleep Medicine, bacteria were recovered in 9 of 11 tests from the breathing tubes of CPAP devices fitted with heated humidifiers.
This is a Gram-positive, spherical-shaped bacteria commonly found on both the skin of humans and animals. This bacteria is known for being the second most common bacterial isolate from human blood and has been known to cause infections in people with compromised immune systems. Typically not a public health pathogen, recent strains of this microorganism has demonstrated antibiotic resistance.
This is a Gram-positive, spherical-shaped bacteria commonly found on both the skin of humans and animals. This bacteria is known for producing compounds that contribute to body odor and has been known to cause infections in people with compromised immune systems. Typically not a public health pathogen, recent strains of this microorganism has demonstrated antibiotic resistance.
This bacteria is a Gram-positive, cocci-shaped, facultative anaerobe. S. epidermidis is part of the human bacterial flora, mostly located on skin. It is not usually pathogenic, however, antibiotic resistant strains have evolved. Most Staphylococcus species are a hardy microorganisms capable of surviving on surfaces and under dry conditions. This bacteria, specifically, is regularly used in quality control, media testing, and pharmacuetical/personal care products testing.
This fungi is facultatively aerobic and can grow both as a yeast and as a filamentous fungus. Candida albicans is a commensal microorganism meaning it normally inhabits the human mouth and gastrointestinal tract but is opportunistic and can cause candidiasis or thrush. Candida albicans can survive for long periods of time without nutrients and is known to form biofilms on medical devices, therefore, disinfection to kill these fungi is very important.
Protocols, test method setups, and results are included in the enclosed reports. In addition to the Biofocus 2017 test findings, included for reference is the 2012 Biofocus document.
According to Healthy Facilities Institute (www.healthyfacilitiesinstitute.com) “Log” stands for logarithm, which is the exponent of 10. For example, Log-2 represents 102 or 10 x 10 or 100. Log Reduction stands for a 10-fold (one decimal) or 90% reduction in numbers of live bacteria.
Another way to look at it is: 1-Log Reduction would reduce the number of bacteria 90%. This means, for example, that 100 bacteria would be reduced to 10, or 10 reduced to 1.
90% .................. 1 Log reduction: Number of germs is 10 times smaller
99% .................. 2 Log reduction: Number of germs is 100 times smaller
99.9% ............... 3 Log reduction: Number of germs is 1000 times smaller
99.99% ............. 4 Log reduction: Number of germs is 10,000 times smaller
99.999% ........... 5 Log reduction: Number of germs is 100,000 times smaller
99.9999% ......... 6 Log reduction: Number of germs is 1,000,000 times smaller
Various pathogen species were used for disinfection testing and the SoClean 2 in all testing facilities/species resulted in a minimum average Log 3 reduction (99.9% Disinfection) with many tests performing over a Log 4 reduction (99.99% Disinfection).
