Microfiber is a synthetic fiber made of polyester and nylon which is so fine that it is comparable to a human hair split lengthwise into between 6-100 pieces, depending upon the quality of the microfiber. Imagine each of the little splits as a "grabber" that can pick up bacteria, dust and dirt.
Microfiber:

• can reach into the tiniest crevices (even those in surfaces which appear smooth to the human eye) and scoop out hidden dirt and bacteria.  
• has a natural static charge that acts like a magnet to attract even the tiniest particles of dirt
• create a capillary action  that draws dirt, grime and bacteria into the center wedge-shaped areas of the cloth rather than just spreading it around.

What Are The Benefits Of Cleaning With Microfiber?

Microfiber cleaning...

• is environmentally friendly
• improves the indoor environment by achieving a cleaner result 
• is extremely cost efficient when you choose high quality,long lasting products 
• is loved by the cleaner because it makes cleaning easy

Microfiber cloths can reduce the consumption of cleaning chemicals in your home up to 90% while at the same time cutting down your exposure to toxic fumes. This can make a big difference for anyone with allergies and chemical sensitivities.
In all areas of our home, including bathrooms and kitchens, microfiber cloths remove 99+% of the bacteria from surfaces, resulting in a cleaner, healthier environment.
High quality microfiber cloths are very durable. They are widely used in commercial cleaning environments and can withstand the rigors of everyday usage.

What Makes Norwex Microfiber Different From Other Microfiber?

1. Imagine a human hair split lengthwise 6 times, so that each of the 6 splits is a "grabber" that picks up dirt, debris and bacteria. That's a microfiber cloth. Now imagine that same hair split lengthwise 100 times so that each of the 100 grabbers does the same. That's a Norwex microfiber cloth. Norwex microfiber is superior to all others on the market, and can remove 99.9% of bacteria using only water. You can actually feel the microfiber grabbing at the surface as you wipe!
2. Norwex microfiber is the world's only Antibac microfiber,. It has a patent-pending silver agent woven into the cloth itself, enabling it to kill bacteria left in the cloth after rinsing within a few hours. No other microfiber can claim this feature.
3. A non-Norwex microfiber cloth will maintain its cleaning ability for up to about 25 washes, and will then become like a regular cotton cloth in its ability to clean. A Norwex Antibac microfiber cloth, on the other hand,  still picks up 99.4% of bacteria after 500 washings!
4. Norwex microfiber can go in the dryer (no fabric softener or bleach). Most other microfiber cloths cannot go in the dryer, which means you have to remember to fish them out of the wash before drying your load. This may seem like a small thing, but functionally speaking, it's a pretty handy feature!
5. All Norwex microfiber products have a full 2 year money-back guarantee. This means that if in that period of time your Norwex Antibac microfiber cloth degrades in some way with normal use and proper care, Norwex will replace it.

What Does The Silver in Norwex Microfiber Do?

Norwex Antibac microfiber cloths & wet mops contain an environmentally-friendly, patent-pending Silver Technology that has been approved by both the US Food and Drug Administration (FDA) and the US Environmental Protection Agency (EPA)! This new technology sets Norwex apart from all other microfiber companies.
Protection 24 hours a day- 7 days a week!
Norwex has developed a unique technology that combines an antibacterial silver-based agent with microfiber. The antibacterial agent is embedded inside tiny microfibers the size of 0.3 denier or smaller.

Testing showed that the bacteria in the microfiber itself were reduced by more than 99.99% after 24 hours, while standard microfiber had a bacteria growth of 14,000.
Laboratory testing has proven that the new Enviro Cloth is effective against E.Coli, Salmonella, Bird Flu, SARS and many other strains of bacteria.
