1. The ZEPA anti-bacterial rear pre-filter captures millions of particles per day.
2. Silent Night's fanless engine has two phases. First is an array of charged
wires.
3. The engine's 'accelerator stage' looks like a metallic cage. This proprietary
lightweight system draws only 39 watts of power.
4. Unlike Brand-X air filters, Silent Night's ultra-pure air is gently and silently
diffused into your environment so you can breathe with confidence and sleep
restfully.

Silent Night’s Double ZEPA
®
Filtration
The highest particulate capture efficiency with no fan.
Virtually Silent operation. (Fan-type units are loud and intrusive).
Super-low cost of operation. Captures millions of unwanted biologicals and allergy
triggers for pennies per day.
ZEPA-500 always operates at maximum performance providing the highest particulate
capture efficiency.
Why ZEPA Filtration?
An average adult’s lung surface area is the size of a
tennis court, and normal breathing is 12 inhalations per minute—about 6
liters of air.
Every HOUR, we inhale 12.7 cubic feet of air (and its
pollutants!).
Children have smaller lungs but their breathing rate is much
higher. It makes sense to have a ZEPA-500 in every closed room where
we or our loved ones spend a lot of time.
Top Filter Efficiency without Fan Noise: Standard air cleaners must be run at their maximum
(noisiest) setting to produce top results. Silent Night always runs on Maximum effectiveness,
yet its amazing fanless ion engine and Double ZEPA Filtration capture nearly 100% of
particulate, silently!
ZEPA 500’s Four Functional Stages
A
Silent Night's 4 fanless stages move hundreds of cubic feet of air per minute (CADR certification is
311). ZEPA-500 tests have produced perfect or near-perfect air at .3, 1 and 5 µ measurements. No
other air cleaning technology can produce results equal to Silent Night.
Brand-X products that are fanless will likely have 95% less Clean Air Delivery Rate (CADR).
Noise, turbulence and light are known sleep interrupters. All of these issues are avoided with
Silent Night. A competitor product will not have an ambient light tracker whereby the units’
light dim in a darkened room. These air purifiers have noisy fans that will create a turbulent
air flow that stirs particles around in your environment. A noisy fan speed does not mean
high effectiveness, which a particle counter can easily prove.
Silent Night's zephyr-gentle air flow gives the ZEPA filters 'capture time' so more particulate
can be collected.
There are billions of particulate at rest in carpet, drapes, furnishing etc. that will not be in the
breathing space unless stirred up by high speed fans or environmental factors, such as open
windows from nearby occupants or traffic. This "kitchen mixer" effect should be avoided as
best as possible as it introduces more particulate to a breathing space. This recommendation
is applicable to all
air purification systems.
