Fast Facts – The Need To Improve IAQ

Research-Validated Disinfection Technologies

Intelli-Safe exclusively uses technologies that have been studied, tested, and measured by peer-reviewed 3rd parties to ensure the safety of occupants and efficacy of our solutions.

UVC Light

UVC light penetrates into the RNA and DNA of pathogens and breaks down their genetic information through a process called Thymine Dimertization. With damaged DNA and RNA, the pathogen cannot reproduce and therefore cannot infect.

This action of UVC disinfection is maximized between the wavelengths of 250nm – 270nm.  However, longterm direct exposure at this range can cause skin and eye irritation.  For this reason, IntelliSafe IAQ products utilize this bandwidth of UVC light for internal purification purposes.


Far UVC, the bandwidth of UVC light from 200nm – 230nm, cannot penetrate the skin’s most superficial layer called the stratum corneum or the outer tear layer of the eye.  In other words, Far UVC is safe for use in occupied spaces.

Additionally, this wavelength of UVC destroys proteins in the walls of viruses and gram-negative bacteria, and therefore requires a smaller dosage in many instances than 250-270nm UVC light.

To ensure proper filtration of UVC light and removal of any ozone byproducts generated in sub-240nm wavelengths, IntelliSafe IAQ exclusively uses USHIO Care222 Far UVC Modules.

HEPA Filtration

High Efficiency Particulate Air (HEPA) filters were originally designed for nuclear power plants, hospitals, and spacecraft to trap airborne particulate matter (PM) in its tight mesh weave.

The Minimum Efficacy Reporting Values (MERV) scale rates HEPA filters as MERV 17 – ability to capture 99.97% of particles in the 0.3-micron range and greater.  According to a renowned NASA study, HEPA filters provide “superior performance for removing virtually 100% of (PM2.5 fine and ultrafine) particulates” including but not limited to spores, dust, pollen, bacteria, allergens, and dander.

Active Carbon Filtration

Active carbon filters, also known as active charcoal, trap volatile organic compounds (VOCs) and odors through a process called adsorption in which molecules stick to the weaved mesh surfaces of the filter.

VOCs, gases created from a variety of products and processes like industrial and auto emissions, chemical disinfectant usage, off gasing from furnishing and polishes, and more, are a hidden danger in facilities which can lead to long-term health risks including cancer.  Properly replaced active carbon filters provide superior defense against these hidden dangers.
