The solution to the transmission of the microbes through the H.V.A.C. system, with branch multi-room systems, is by preventing them from entering the system in the first place, this is what this product was designed to do. Sanders Containment Filter is a new, synthetic media developed and now available that has efficiencies higher than HEPA, 99.9998% @.1 micron. This is when it was independently tested on virus VFE (please see our independent test reports). This media's main advantage is that unlike old, hard-sided, micro-fine glass HEPA, it is a soft flexible pad with a low static pressure; .17 W.C. @ 125 cfm/sq. ft. For the first time, this allows for HEPA or near HEPA filtration of the return air directly, in any room. This means that now all rooms may be filtered with HEPA or near-HEPA air quality without any reconstruction costs of transforming the HVAC unit, these work on all previously installed units. By attaching this pad over every return vent you will capture any microbe, as it is about to enter the HVAC system (this is known as source capture). Since all vents must be filtered, a uniform static pressure is achieved and the system is still in balance.The product has such low resistance in the 100 Series, it also will work on very low flow P-Tac or through-wall systems.

​

       For large areas like airports, hospitals, schools, governmental buildings, or convention centers, the filter is placed on the air entering ports of a high velocity floor fan, up to 3000 cfm. Finding a solution to the transmission of the microbe’s indirect contact in any air space is essential to help prevent nososomial transmission to patients and personnel using or re-using common areas. This could easily be life saving technology when there is not an outbreak, as seen with the current COVID-19 pandemic, as well. This is not limited to hospitals but also should be considered in nursing homes, cruises, subway stations, and any other well-populated indoor areas. This concept of preparing for prevention instead of attacking the virus after it has affected people can change the way we think of clean air and the particles the air, many of which that can be harmful, contains. Additionally, this could change the ability for any immune-compromised patients, oncology patients, infants, and the elderly to live their day-to-day lives by drastically reducing the risk that they would come in contact with a submicron particle that may be virulent.
