Pre-Filter – our 4" thick pre-filter is designed to remove the larger sized
dust and pollen particles and when replaced on schedule extends the life of
the main filter. This filter should be replaced with every 6-9 months of use.
This is available as either a standard or carbon pre-filter. The standard is
recommended for allergy sufferers and the carbon for those who require
light odor removal.
Foam Filter – the foam filter is a permanent filter at the top of the air
purifier by the air intake. It catches the largest dust particles and can be
cleaned by lightly vacuuming or brushing with a broom. This filter cannot be
replaced.
Commercial Carbon Filter – The Commercial Carbon filter can be used in
place of the main HEPA filter for advanced gas, VOC or smoke removal. It
has 14 pounds of activated carbon in an optimized V bank shape for
maximum effectiveness in gas and odor adsorption. To use this filter you
will need to install the carbon filter kit (sold separately).
EC Advantages
More efficient and use up to 90% less power.
•
More reliable since it runs cooler.
•
More compact.
•
Quieter - no motor hum that you can get with an AC motor.
•
Why does the motor/fan start and stop more slowly than an AC motor? EC
motors have a soft start programmed into the motor to limit the start-up
current the motor draws (there are electronics built into the motor). The
ramp down after power is removed is only a function of the inertia of the fan
and the friction of the bearing system. A high quality bearing system will
take longer to slow down and stop since the friction is minimized (alignment
is better, lubricant is better, etc.).
EC Motor/Fan.
When you selected the Erik Air Purifier you chose the latest
and best German engineered motor available. EC
(Electrically Commutated) motors use electronics to
convert the AC voltage to DC to run the motor.
