High Efficiency Particulate Air Filter

High Efficiency Particulate Air Filtration:

Particulate matter is comprised of very small particles of solid or liquid matter that vary in size, chemical composition and source. Particles can remain suspended in air for long periods of time.  The smaller the particle, the longer it will remain airborne.

As reported by the Department of Family and Community Medicine, University of Toronto, when inhaled, fine particles are capable of being deposited in, and could damage the airways of, the lower
respiratory tract and the gas-exchanging portions of the lung.

The Asthma & Allergy Foundation of America states that the most effective kind of mechanical filter is called the high-efficiency particulate air (or HEPA) filter. To qualify as a HEPA filter, a device must be able to capture at least 99.97% percent of all particles 0.3 microns or more in diameter that enter it.

The rubberized gasket on the DVA 400 HEPA filter forms a tight seal inside the system to ensure air passes through the HEPA and not around it.  The filter change  interval is  determined  by  particulate   matter, temperature and humidity.  The typical HEPA life is 18 to 30 months.  The humidistat  will  indicate when  the filter should be changed.

Germicidal UltraViolet Light Technology

Germicidal UV:

The DVA 400’s optional Germicidal Ultraviolet Light is specially designed to produce the highest amount of UV radiation at the peak of germicidal effectiveness.  A UV radiation level of 265 nanmeters (nm) is the most  lethal wavelength to airborne microorganisms, such as bacteria, viruses and molds. 

The DVA is equipped with a lamp shutoff switch, and a sight glass for safe and easy lamp inspection. In addition, a protective cover with a safety interlock switch immediately deactivates the lamp before the service technician or homeowner can access or service the unit.

Germicidal lamps are not designed or manufactured equally.  Each component of the lamp directly influences the effectiveness of the light.  The hard glass tubing used to house the DVA 400 UV light yields the highest UV transmittance possible.  One of the most critical steps in lamp production is Lamp Processing, which involves evacuating the lamp body while treating the filaments and then dosing the proper amount of pressure of noble gases and mercury into the lamp.
 

UV-C, the germicidal wavelength, damages the nucleic acid of microorganisms by forming covalent bonds between certain adjacent bases in the DNA. The formation of such bonds prevent  the DNA  from  being  unzipped  for replication,  and  the organism  is  unable  to reproduce. In fact, when the organism tries to replicate, it dies.

UV lamps are equipped with high quality, US-made hard quartz lamps for optimum lamp performance and reliability. These lamps are rated for at least 9,000 hours (1 year) when installed and used in accordance with the operating manual. Lamps may last longer in some situations, but annual lamp replacement is recommended since UVG output is typically reduced by about 25% after 9,000 hours and drops off more rapidly afterward.
