The role of ‘no-touch’ automated room disinfection systems in infection prevention and control
The role of ‘no-touch’ automated room disinfection systems in infection prevention and control
"A number of NTD systems have emerged, which remove or reduce reliance on the operator to ensure distribution, contact time and process repeatability, and aim to improve the level of disinfection and thus mitigate the increased risk from the prior room occupant. Available NTD systems include hydrogen peroxide (H2O2) vapour systems, aerosolized hydrogen peroxide (aHP) and ultraviolet radiation. These systems have important differences in their active agent, delivery mechanism, efficacy, process time and ease of use. Typically, there is a trade-off between time and effectiveness among NTD systems. The choice of NTD system should be influenced by the intended application, the evidence base for effectiveness, practicalities of implementation and cost constraints."

Resistance of Aerosolized Bacterial Viruses to Four Germicidal Products
Resistance of Aerosolized Bacterial Viruses to Four Germicidal Products
{Discusses whether disinfectants such as CD are effective in air.} Viral diseases can spread through a variety of routes including aerosols. Yet, limited data are available on the efficacy of aerosolized chemicals to reduce viral loads in the air. Bacteriophages (phages) are often used as surrogates for hazardous viruses in aerosol studies because they are inexpensive, easy to handle, and safe for laboratory workers. Moreover, several of these bacterial viruses display physical characteristics similar to pathogenic human and animal viruses, like morphological size, type of nucleic acids, capsid morphology, and the presence of an envelope. In this study, the efficacy of four chemicals was evaluated on four airborne phages at two different relative humidity levels. Non-tailed bacteriophages MS2 (single-stranded RNA), ϕ6 (double-stranded RNA, enveloped), PR772 (double-stranded DNA), and ϕX174 (single-stranded DNA) were first aerosolized in a 55L rotative environmental chamber at 19°C with 25% and 50% relative humidity. Then, hydrogen peroxide, Eugenol (phenylpropene used in commercial perfumes and flavorings), Mist® (automobile disinfectant containing Triethylene glycol), and Pledge® (multisurface disinfectant containing Isopropanol, n-Alkyl Dimethyl Benzyl Amonium Chlorides, and n-Alkyl Dimethyl Ethylbenzyl Ammonium Chloride) were nebulized with the phages using a separate nebulizer. Aerosols were maintained in suspension during 10 minutes, 1 hour, and 2 hours. Viral aerosols were sampled using an SKC BioSampler and samples were analyzed using qPCR and plaque assays. The resistance levels of the four phages varied depending on the relative humidity (RH) and germicidal products tested. Phage MS2 was the most stable airborne virus under the environmental conditions tested while phage PR772 was the least stable. Pledge® and Eugenol reduced the infectivity of all airborne phages tested. At 25% RH, Pledge® and Eugenol were more effective at reducing infectivity of RNA phages ϕ6 and MS2. At 50% RH, Pledge® was the most effective agent against phage MS2. These findings illustrate that various airborne viruses should be tested to demonstrate the effectiveness of germicidal treatments. This research also provides a set of parameters for testing germicidal products in large-scale settings to reduce the risk of virus transmission.

Humidifier vs Diffuser: Which One Should You Buy
Humidifier vs Diffuser: Which One Should You Buy
"ABS plastic is used in the production of diffusers because they are made out of oil-based resources and boast of a much higher melting point (more temperature resistant) than PP plastic. As such, they cannot be broken down or corroded by the acidic chemical composition of some essential oils." "Plastic aside, other components of a diffuser like the metal atomizer and absorption rings are specifically designed to withstand the corrosiveness of essential oils." "Diffusers are much more powerful than humidifiers. They break down essential oils into an ultra-thin fragranced mist that's easily dispersed over a wider distance for longer periods. The cool or warm mist generated by humidifiers from the vaporization of water molecules is only able to travel over shorter distances. This low dispersion range is because humidifiers usually have larger atomizer, which subsequently produces bigger, thicker, and heavier mist concentration."
