The NanoTowels are made from man-made materials, but that is the only way to make it durable and have it's unique cleaning characteristics.
There are far less synthetics used in the NanoTowel than used to make just ONE bottle of chemical spray cleaner which is used and discarded.
In fact, one pack of NanoTowels can be washed and reused hundreds of times, and replace dozens of non-reusable plastic bottles full of chemical cleaners and hundreds of rolls of paper towels over the long haul. What that means, is that you will use dramatically less natural and man-made resources to clean over the course of the life of the NanoTowels, so your ecological footprint becomes a tiny fraction of what it used to be.
Don't forget, you are also dramatically reducing the amount of chemicals in your household, which could lead to better overall wellness!
