When most of us think about air cleaning, we think about filters. The HVAC systems in our homes use HEPA filters and  so do most of the air cleaning systems sold at big box hardware stores. HEPA is an acronym for “high efficiency particulate air.” According to the EPA, this type of air filter can, in theory, remove at least 99.97% of dust, pollen, mold, bacteria, and any airborne particles with a size of 0.3 microns (µm).

Recent findings regarding the transmission of COVID-19 indicate that the SARS CoV-2 virus that causes COVID-19, is transmitted through droplets as well as aerosols, particles much smaller than the 0.3 micron threshold for a HEPA filter.  According to Penn Medicine,

“Traditionally, droplets are defined as large (>5 microns) aqueous bodies. However, airborne (or aerosolized) transmission of the virus has been proposed as a source of infection almost since the inception of the COVID pandemic.

By comparison to droplets, aerosolized particles are infinitesimal. Size alone is not the only important distinction: Droplets fall to earth quickly, but aerosols can travel on air currents potentially for hours. Thus aerosolized viruses are likely to be much more infectious than viruses bound to respiratory droplets, and much more difficult to avoid.”

CASPR, Continuous Air and Surface Pathogen Reduction systems, send oxidizing molecules out into the air to proactively neutralize both droplets and aerosolized viruses.

You have probably heard the phrase, “the best defense is a good offense.”  CASPR’s oxidizing molecules are a great offense, traveling out into your environment to attack pathogens wherever they are, in the air or on surfaces. Filters act like a goalie defending the goal line, stopping a ball from entering the net. Unlike filter-based air cleaning systems, CASPR can address viruses in the air and on surfaces, particularly surfaces that regular cleaning may miss.

“What if I already bought a HEPA filter machine?  Can I use CASPR?”

The answer is absolutely, 100% yes. Having both a strong offense and a strong defense is an optimal way to protect your space. The two technologies work together well and can complement each other.
