Performance Criteria HealthWay DFS FILTRATION SYSTEM UV &UVGI Filtration Efficiency Enable 99.999999 % system filtration efficiency down to 0.007 micron – at lower pressure drop of HEPA see table 1 The technology addresses the viral size ultrafine particles arrest efficiently System filtration efficiency - double HEPA filtration possible due to the lower pressure drop of the primary DFS filters. This eliminates the need for UVGI or additional terminal filters. Doesn't address capturing particles, including spores and viral size ultrafine particles efficiently Efficiency is only linked to the intensity, wavelength 254-270 nm and dose of exposure/time but not in reducing any airborne particulates which are known to have adverse health effects including respiratory and cardiovascular diseases Microbial inhibition & Bioburden DFS filters are highly energy efficient and result in extremely low bio burden in cleanrooms They create high energy field that leads to deactivating viable microbes such as bacteria, fungus and viruses Lower Bioburden of bacteria, viruses and fungus Works only if UV tube intensity is maintained constantly and when system is equipped with filters against UV Destructive effects of UV can be reversed by photoreactivation It requires UV tube to be free from dust and maintaining a high URV Terminal cleanroom filters This is essential since HVAC systems can introduce contamination, which can clog or damage terminal filters. With DFS in Duct Filters, terminal filters should never require replacement or maintenance. NA Typical designs requires terminal HEPA filters Maintenance Costs Lower Maintenance Costs DFS filters can last up to three times longer life than conventional UVGI Higher maintenance cost due to life cycle and loading density Achieving ISO classes The HealthWay DFS filters provide the necessary filtration for such applications. Only blank ceiling diffusers are required for these applications. No terminals required for ISO Class 6 and above NA Doesn't apply to cleanroom particulate count classes Impact on electrical wiring seals and insulation material DFS system doesn't impact HVAC material or building material integrity High radiation may deteriorate exposed building material Filter Replacement Less filter replacement frequency Filters replaced externally - less down time and total protection of cleanroom processes and equipment NA VOC mitigation Addresses Volatile Organic Pollutants with its optional VOC bank Doesn't address any VOC pollutants Safety Safe operation due to self-contained design Higher risk of exposure to UV radiation which may lead to skin burns, eye damage
