Norwex microfiber cloths are higher quality than other microfiber products for several reasons. They are machine washable up to 200 times, have finished edges that do not fray, and are more absorbent due to their dense weave of thin fibers. Norwex cloths also contain an antibacterial silver additive that is embedded in the fibers themselves, so it does not wash out. This allows the cloths to remain cleaner and last for many washes under a two-year warranty. The document provides details on how the silver works and the type of silver used in Norwex cloths.

1. Whyis Norwex microfiber better?
There are manymicrofiber products currentlyon the market makingit
complicated for the consumer to determine what the difference is
between one product and the next.
While at first they may appearsimilar,compare the quality.
• Find out if the products are machine washable and for how many
washes theyare guaranteed to last. Other products recommend
hand washingonly,indicatingtheymay not last long.
• Look at the edges of the cloths;if the edges are not finished well
they will fray when washed, reducingthe lifespan ofthe cloth.
• Prices for microfiber cloths are usuallydirectlyrelated to the quality
of the product.If the price is lower, it is a good indication of
lesser quality.
• Any cloth cleans because of its fibers.How well a cloth cleans is
determined bytwo factors: The densityand the absorbency.
Traditional cloths are not designed to pick up dirt particles as
efficiently, due to the rounded surface of threads.
Microfiber cloths have millions of wedge-shaped cross sections
that remove and trap the dirt.
The properties of Norwex microfiber cloths are nothing less than
exceptional. Our micro fiber is 200 times thinner than a human
hair, yet incredibly durable. The weaving of the microfiber makes
up many small pockets for dirt and bacteria to collect rather than
passing under the cloth. The weaving gives the cloth two hundred
times the cleaning surface of regular cloths. This process also
makes the cloth eight times more absorbent than regular cloths.
The pockets created by the fibers work using capillary action.
Why Ours are Different?
1. Antibacterial -Now you might say that is not a concern, BUT this
allows the cloths to remain cleaner. You don't have to launder ours

2. after every use thus being more respectful to the environment!
2. Two year warranty. Many of the inexpensivestore bought
microfibers lose a lot of theirwicking abilityafter 5 -10 washes,leaving
you with a cloth that no longer works as well or works as well as paper
towel. In this respect these cheap microfibers MUST be used with
some type of cleaner to actuallyclean.
3. Quality - we have 1/200 fiber counts and high quality. See above
NOTES about testingquality.
b. How does the silver in the cloth work?
Silver interrupts a cell’s ability to form chemical bonds essential to
its survival. Bacteria, viruses and fungi need the bonds for their
oxygen metabolism. In the SIMPLEST of TERMS – it suffocates
them. Essentially the organism suffocates and dies within
minutes.
The Antibacterial agent is embedded inside tinymicrofibers the size of
0.3 Denier or smaller.
• Denier is a unit of measure for the linearmass of fibers. A single
strand of silkis one denier.A fiber is generallyconsidered a
microfiber if it is 1 denier or less.
Please note that the silver-based agent that we use is based on micro,
not nano-technologyand that it is physicallyembedded into the cloth,
so that it is not leached out to any notable degree upon use or
washing. When microbes come into contact with this agent they tend
do die rather rapidly,and we havea measured 99.9% reduction after
24 hours (but the agent is working well before then to destroy
bacteria).
One limiting factor of Silver is it only kills micro-organisms
when they are in contact with it for a sufficient period of
time. So cloths that have residual chemicals/fabric

3. softeners/soapy residues on the fibres' do not allow silver to
contact germs within the cloths. It COATS the fibre, keeping the
silver and germ separated. THUS WASHING and USE
instructions are important.
c. What kind of silveris it?
The silverin the cloth is not pure silver,it is zirconium silver
phosphate.
The agent does NOT affect cleaningabilitybut does inhibit growth of
bacteria and molds in/on the microfibers.
“use water to clean with microfiber, use soap and water to clean
microfiber.”
*** Norwex has developed the patent pending silver
agent which is part of the fiber. Other microfiber
that claims to have silver is not embedded but is a
covering which can leach and wear off. Norwex silver
does not wear off. Our regular cloths contain 70%
polyester and 30% polyamide and 2.9 million meters
of fiber which is top quality. We also have a 2 year
warranty on our microfiber, but they last a lot
longer than that if cared for properly. This
includes the silver content as well.
It is not silver nitrate – it is a form of silver
which is physically and chemically embedded within
the microfiber itself so that it does not leach out
of the fiber – it is basically in there for the life
of the cloth – which is why it is so safe to use and
safe for the environment – because we are not
leaving little bits of silver everywhere! We are
the only company that has been able to do what we

4. do.
The silver is a micro-silver-based agent. When our
microfiber is produced, it starts as a molten liquid
and it is at this time that the silver-based agent
is added. It is then extruded (forced through)
something like a shower head. It starts out as a
liquid on one end, and comes out microfiber on the
other end. The silver-based agent is added when it
is in a liquid form and is therefore physically
embedded within the fiber – it does not wash out.
The silver we use we obtain from a secondary or even
tertiary source and it is not pure silver.
***Currently, the science involved in the manufacturing process of our
antibac cloths is in the stage of 'Patent Pending' and subject to the
protections that such a status provides in the various jurisdictions in
which Norwex operates. Upon completion of the application process
and granting of the patent number, it will be valid for a period of 20
years. We are confident however that long prior to the risk of this
patent expiring, we will be in possession of evenmore superior
technology to assist us in providing global options to radically reduce
the use of chemicals.
I hope that this can clarify some issues with the ‘other microfiber’ out
there. Remember all the positivethings about ourmicrofiber, the
qualityofour products,and ourwarranties.
