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
Having many pets, new carpeting, paint fumes, heavy smoking,
city pollution, etc
How do I know when the cartridge needs replaceing?
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 replaceing. If it is dark blue, grey or black it definately needs to be replaced. Call us at 1-877-523-7800.
How long do you think my unit will
The unit should last well over 20 years or more if properly
maintained. It is the filter that must be replaced when
Where should I place the unit for maximum
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
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
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 used for?
Carbon and zeolite are used to remove gases and odors. Both have properties that allow them to adsorb gaseous materials.

CFM (Cubic Feet per Minute) a measurement of air flow.
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 specific
Revolutions Per Minute (RPM) is a measure of speed for any
rotating device. Typically found in specifications for
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 pressure
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
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 structure.
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

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.

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 sticks together.
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 warranty is legal concept or doctrine that holds
manufacturers or sellers responsible, or liable, for harm
caused by defective products sold in the marketplace.
A limited warranty is a warranty that imposes certain
limitations, and is therefore not a full warranty.
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.

Air-Conditioning Engineers. ASHRAE publishes Standards for
Ventilation for Acceptable Indoor Air Quality.
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
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
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
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
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.
