ANSWERS TO YOUR QUESTIONS
What are the guarantees?
The motor, fan and other working parts come with a
limited lifetime warranty and a conditional 10
year mechanical warranty.
What would cause a filter
to fill up in less time?
Having many pets, new carpeting, paint fumes,
heavy smoking, city pollution, etc
How do I know when the
cartridge needs replacing?
The cartridge can filter up to 9000
hours of running time. If you have it on 24/7 it
will last one full year. It may need to be
replaced sooner if your have pets, carpets or more
dust than the average home. You can usually tell
by the colour. If the material in the main
cartridge is no longer blue it may need replacing.
If it is dark blue, grey or black it definitely
needs to be replaced. Call us at 1-877-523-7800.
How long do you think my unit will last?
The unit should last well over 20 years or more if
properly maintained. It is the filter that must be
replaced when needed.
Where should I place the
unit for maximum effectiveness?
It can be placed anywhere in a room, including
corners. Ideally close to an air intake vent. The
air cleaner should be placed in the bedroom at
night with the door closed in order to produce the
best personal results. The best room in the house
to use a single machine is the bedroom.
How much space does the
air cleaner effectively clean?
It will clean an average bedroom in about 10
minutes with the door closed. In technical terms,
it cleans up to 1,600 square feet per hour. The
Compact model cleans up to 700 square feet. (All
estimates assume 8 ft. ceilings.)
Does the unit require any special maintenance?
Periodic (once a month) vacuuming of the front of
the pre-filter with the brush attachment of your
vacuum cleaner is the only regular maintenance
required for the air cleaner.
How much electricity is
required to run the air cleaner?
Your Nutri-Tech uses an ordinary 120 volt outlet.
Maximum draw is about 135 watts on the high
setting or 1 cent per hour, average cost.
What are carbon and zeolite
Carbon and zeolite are used to remove gases and
odors. Both have properties that allow them to
adsorb gaseous materials.
A guide to understanding
air cleaning terms.
CFM (Cubic Feet per Minute) a measurement of air
Although there is no universally accepted method
for comparing air-cleaning devices, several
investigators of portable air-cleaning units have
expressed their results as a "Clean Air Delivery
Rate" or CADR. The CADR is the product of the unit
efficiency and the airflow rate, and is a measure
of the number of CFM of air it cleans of a
Revolutions Per Minute (RPM) is a measure of speed
for any rotating device. Typically found in
specifications for motors.
The DOP Military Standard is the standard set by
the federal government to rate particle reduction
by HEPA filters. This test rates high-efficiency
filters by the percentage of 0.3 micron size
particles of dioctylphthalate (DOP) smoke they
HEPA stands for High Efficiency Particulate Air,
and like the name says, these filters are designed
to remove 99.97% of all airborne pollutants 0.3
microns or larger from the air that passes through
the filter (these include tobacco smoke, household
dust and pollen).
Pounds per Square Foot (PSF). A measurement of air
Carbon, the sixth most abundant element in the
universe, has been known since ancient times. Many
natural substances of base materials are used to
make carbon. The most common of these are wood,
coal, lignite, and coconut shell.
Amorphous carbon is formed when a
material containing carbon is burned without
enough oxygen for it to burn completely.
ACTIVATED CARBON or AC
Activated carbon is the generic term used to
describe a family of carbonaceous adsorbents with
a highly crystalline form and extensively
developed internal pore structure. Activation
creates a fast internal pore network and imparts
certain surface chemistries (functional groups)
inside each particle. Thus activation gives carbon
its unique filtering characteristics.
Zeolite is a mineral with a unique interconnecting
lattice structure. This lattice structure is
arranged to form a honeycomb framework of
consistent diameter interconnecting channels and
pores. Negatively charged alumina and neutrally
charged silica tetrahedral building blocks are
stacked to produce the open three-dimensional
honeycomb framework. Zeolites actually attract
odors & gases and trap them in its crystalline
A pre-filter is the primary layer of filtration
that collects large particles before they reach
the HEPA filter. Eliminating these larger
particles, dust and hair extends the life of your
HEPA filter. Occasional vacuuming of the exterior
of the unit will help extend life of the filters
and will also prolong the HEPA filter life.
When a gas or vapor is brought into contact with a
solid, the solid takes up part of it. The
molecules that disappear from the gas either enter
the inside of the solid, or remain on the outside
attached to the surface. The former phenomenon is
termed absorption (or dissolution) and the latter
Trap is the process of gasses and particulate
matter attaching to the surface of the carbon and
or zeolite structures.
There are many simple electronic devices that
claim to clean the air in your home by making
negative ions and ozone. The claim is
accurate--they do make both ozone and negative
ions, and they do clean the air in your home.
However, that's not the whole story. Also ozone
gives off the "fresh" smell that occurs after a
thunderstorm (a potent producer of ozone)
Ozone is produced indirectly by ion generators.
A micron is a unit of length equal to 1 millionth
of a meter or .000039th (39 millionth) of an inch.
Another name for micron is micrometer.
Particulate Matter Up to 10 Microns in Diameter
The number 10 refers to the particle size measured
PM 10's are widely considered the most dangerous
to human health.
3-Speed refers to a variable speed selection
control on your air cleaner. This control allows
you to operate your air cleaner on low, medium or
high settings depending upon your needs.
The blower wheel is a squirrel cage type wheel
whose purpose is to move the air through the room.
A blower wheel is more efficient than a fan as it
will move more air and resists clogging.
A standard developed for measuring particulate
matter in a pre defined area.
The Association of Home Appliance Manufacturers
(AHAM) is an organization that represents the
manufacturers of home appliances and creates
standards with large manufacturers. While it has
an admirable mission, it is important to note that
AHAM is not a HEPA standard and seems to have been
developed to resemble the output of electrostatic
precipitators, a technologically inferior air
cleaning method. It is for that reason that the
output ratings are only valid for the first 72
hours (3 days) of operation.
The electrostatic stage filters the air using
static electricity by having a static charge on
the filter to allow airborne particles to "stick"
to the filter, just like static-charged clothing
Ion generators act by charging the particles in a
room so that they are attracted the unit. Ion
generators remove small particles (e.g., tobacco
smoke) from the indoor air. These devices provide
a benefit by rectifying a hypothesized ion

A limited warranty is a warranty that imposes
certain limitations, and is therefore not a full
PRO RATED WARRANTY
The main filter cartridge in Nutri-Tec air
purifiers is backed by the 1 year pro-rated
warranty. Under this pro-rated warranty the user
of a Nutri-Tech Air cleaner becomes eligible to
receive a new filter cartridge at a partial cost
if the unit fails within the duration period of
the pro-rated warranty period. This warranty
applies to the Nutri-Tech units used under normal
residential conditions only. Under the pro rated
warranty the sooner you have to replace the
filter, the less money you pay.
A guarantee is an assurance for the fulfillment of
a conditions put forth by the manufacturer.

Standards for Ventilation for Acceptable Indoor
Molds produce tiny spores to reproduce, just as
plants produce seeds. Mold spores waft through the
indoor and outdoor air continually. When mold
spores land on a damp spot indoors, they may begin
growing and digesting whatever they are growing on
in order to survive. There are molds that can grow
on wood, paper, carpet, and foods. When excessive
moisture or water accumulates indoors, mold growth
will often occur, particularly if the moisture
problem remains undiscovered or unaddressed. Molds
can trigger asthma episodes in individuals with an
allergic reaction to mold.
SICK BUILDING SYNDROME
The term "sick building syndrome" (SBS) is used to
describe situations in which building occupants
experience acute health and comfort effects that
appear to be linked to time spent in a building,
but no specific illness or cause can be
identified. The complaints may be localized in a
particular room or zone, or may be widespread
throughout the building.
The following have been cited causes of or
contributing factors to sick building syndrome:
Inadequate ventilation: Inadequate ventilation,
which may occur if heating, ventilating, and air
conditioning (HVAC) systems do not effectively
distribute air to people in the building.
Chemical contaminants from indoor
sources: Most indoor air pollution comes from
sources inside the building. For example,
adhesives, carpeting, upholstery, manufactured
wood products, copy machines, pesticides, and
cleaning agents may emit volatile organic
compounds (VOCs), including formaldehyde.
Environmental tobacco smoke contributes high
levels of VOCs, other toxic compounds, and
respirable particulate matter. Research shows that
some VOCs can cause chronic and acute health
effects at high concentrations, and some are known
carcinogens. Low to moderate levels of multiple
VOCs may also produce acute reactions.
Combustion products such as carbon
monoxide, nitrogen dioxide, as well as respirable
particles, can come from unvented kerosene and gas
space heaters, wood stoves, fireplaces and gas
Chemical contaminants from outdoor sources: The
outdoor air that enters a building can be a source
of indoor air pollution. For example, pollutants
from motor vehicle exhausts; plumbing vents, and
building exhausts (e.g., bathrooms and kitchens)
can enter the building through poorly located air
intake vents, windows, and other openings. In
addition, combustion products can enter a building
from a nearby garage.
PARTICLE COUNT PER CUBIC FOOT
Particle Count per Cubic Foot is a unit of measure
to classify the amount of a particular size of
particles in a cubic foot of air.
An air cleaner must constantly recirculate indoor
air in order to effectively reduce concentrations
of airborne particulate contamination. Cleaning
the total volume of air contained within a room is
the equivalent of completely changing the air in
that room. Air cleaner filtration capacity is
expressed as the number of air changes per hour
(ACH). For air cleaners of equivalent filter
effectiveness, a higher ACH rating yields higher
levels of air quality improvement.
ROOM AIR CLEANER
Room air cleaners help with allergies by helping
people live in cleaner, healthier environments. By
sleeping in a room with an air cleaner, you will
breathe much cleaner air all night long. And by
also having an air cleaner in your office, or any
other room where you spend a lot of time, you will
maximize your clean air intake and minimize the
allergens you breathe. Even if you have a good
filter on your central air conditioning system, a
room air cleaner will increase the purity of the
air you breathe.
Many room air cleaners can go with you. If your
den and your bedroom are similar sizes, you can
move your air cleaner to the room you're in.
