Congratulations on your choice of the Silent Night fanless air purifier. Its
technologies have been validated by leading university scientists, and
reported in respected scientific journals. Inventor Stan Weinberg owns
five patents on this remarkable Silent Ion-Drive technology.
The Silent Night ZEPA-311 is the biggest innovation in air purification. This
is because it is the world’s most effective particulate remover - while also
being the quietest air purifier ever invented! And it does it all with an
impressive 311 Clean Air Delivery Rate purifying up to 500 square feet.
The ZEPA-311 model uses an electrostatic force of negatively charged
particles being attracted to positively charged particles to accelerate air
and its pollutants through two charge-sensitive filters.
In April 2013, IBR, a lab certified by the Association of Household
Appliance Manufacturers (AHAM) established Silent Night’s official Clean
Air Delivery Rate to be rated at 311 CADR or over 300 cubic feet per
minute of air movement!
Testing has been done with worst case (hardest to capture) MPPS (most
penetrating particle size) of .3 microns, which is used in the Centers for
Disease Control and Prevention (CDC), Intertek and IBR.
Only Intertek and IBR are certified to do AHAM testing. The rules consider air
flow, room size, distance from the appliance, time of operation, and the
reduction of particles down to .1 microns in diameter. Some viruses and all
bacteria fall in the ranges that are measured. We also find mold spores,
pollen, pet dander, smoke particulate, and the byproduct of human
habitation: house dust (80% of which is from human skin flakes).
Using a 13’ x 16’ bedroom with a 10’ ceiling and a closed door (the AHAM testroom volume), Silent Night processes an air volume equal to that room size
every 15 minutes (96 times per day). The machine is most effective in a closed
room such as a bedroom, office, etc. More than one unit may be necessary in
larger areas where new pollution is constantly added by life’s activities.
Your ZEPA-311 is designed to run 24/7. You can Breathe with Confidence®
knowing your Silent Night® will remove millions of airborne particles, dust,
mold spores, dander, smoke, pollen, allergens, germs, viruses and volatile
organic compounds (VOC’s).
