versus other carbon block filters
I n t r o d u c t i o n ...
First, to understand any filter comparison, you should be acquainted with the terms "nominal" and "absolute".
Absolute rating means, nothing above the rated level will pass through the medium. Absolute is usually used to identity filters which will be destined for bacteria or virus protection.
Nominal rating means that 80% of particles above the rated level will be held back. This means 20% of the rated level will pass through the filter.
Also, you should realize that a lot of filter specifications are produced after only running a few hundred liters of water. Not NanoCarb. NanoCarb filters perform throughout their service life, which ends when the filter no longer permits water to pass. No guessing, true anti-overuse, simple and safe.
Regular carbon block matrix filters (which are the well known brands), are manufactured through the continuous extrusion method. This method produces carbon block material with ratings of 1 to 20 (or sometimes higher) micron(s). These filters are rarely identified as either nominal or absolute. Most of these are nominal ratings which many do not indicate explicitly in their literature. This may add to the confusion for the general public.
The magical outer wrap!
These carbon block types are then wrapped (covered) with a layer of absolute membrane material in order to then claim to be 1.0 to 0.5 to 0.2 micron absolute. So the actual viral barrier is assured by a thin (probably 1/8" or less) membrane material which is put under full force of the water entry. These same membranes are usually used in a pleated configuration in order to lower the surface stress of the incoming water flow. But with carbon block, these membranes can only have the outer surface area to lower this same applied stress, which then increases chances for viral passage. Some use more than one layer, but at the end of the day, these are merely attempts to delay the inevitable passage of micro-organisms. Also, many of these filters will not specifically identify the absolute rating of both the outer wrap and the carbon block in order to make it seem like the total filter offers the highest rating.
In most cases, Regular carbon block filters will have a notice on the label in very small print indicating that "the filter should not be used where the water may be of micro-biologically unknown quality". Yes but, what if your city water gets that way with some viruses or parasites. What happens then?
The secret of NanoCarb filters is all in a patented and unique sintered process... the only one of its kind in the World.
No other carbon block filter is manufactured by sintering a coconut carbon powder bound by micro-particles of food grade polymer (gur). This precision batch process produces a carbon block material that is so dense, this would explain why a 10" NanoCarb filter actually weighs in at a hefty 1.50 lbs. This carbon density, bound by the micro polymers, forces water through restricted avenues in the carbon matrix.
The matrix is so dense and the passivity is so selective, that its micron rating through-out the filter material is an astounding 0.45 micron absolute (or 0.20 micron absolute with bubble test which most companies use to rate their filters).
With an unequaled and generous radial depth (outer surface to inner core) of 7/8", and NanoCarb's absolute rating of 0.45 micron, NanoCarb means no bacteria and viruses. Such organisms simply cannot make their way through every nick and cranny to then pass through. They get caught inside the filter and eventually, unable to grow because of such tight quarters, most will simply die.
Hence, and not surprisingly, Polio virus (the smallest known virus) lab testing has shown during a six month study that no passage was evident under normal, on/off real life conditions.
Depending on the overall initial water quality, NanoCarb filters can be used alone, or in double or triple filter housing configurations. Because NanoCarb filters are more expensive than standard carbon block filters, you can use a three stage system consisting of a 1 micron (nominal) sediment depth filter, a 1 micron (nominal) regular known brand carbon block filter and finish off with a 0.45 micron (absolute) NanoCarb filter. This will ensure longer service runs per NanoCarb cartridge.
Also, since the NanoCarb (1:1 ratio) system does not waste water like reverse osmosis does (5:1 ratio), the prefilters will not be over taxed. What you consume is what is filtered, when you wish to consume. So all filters last much longer.
The NANOCARB manufacturing process involves the use of coconut shell carbon which is reduced to microscopic nano-powder. The carbon powder is then activated by high intensity steam in order to create micro-cracks with millions of filtering channels in each particle. The gradients of these micro-cracks are as follows:
As illustrated in the diagram below, water enters the filtering medium and the polymer binding ensures that water is channeled through the microscopic carbon particles which trap bacteria and other living organisms while also absorbing chemicals.
NANOCARB's uniqueness stems from the fact that the filtration block or structure is entirely made of activated carbon which by itself achieves a mechanical filtration of 0.45 micron absolute and an adsorption level of 0.003 micron. No other filter on the market can achieve this since they use other means to filter out particles down to 0.5 micron whatever.
The section below explains
how the most widely used similar filters function compared to NanoCarb.
- A NANOCARB filter has a surface area equal to about 11 professional soccer fields.
- One gram of NANOCARB material has a surface area of 16,146 square feet (1500 square meters).
- Water traveling through the NANOCARB filter wall of 0.78th of an inch is equal to traveling a distance of 656 feet (200 meters) in human terms.
This revolutionary and unique process replaces nanofiltration at 0.003 microns due to the capacity of filtration by adsorption (passage of a liquid in a solid).
The resulting production of NANOCARB filtration systems is used mainly by the general public for Point-of-Use (POU) applications, without using silver salts (such as silver impregnated carbon which is known as being cancer causing).
NANOCARB filtration systems purify the water by removing all;
The duration of the NANOCARB cartridge depends on the water quality with typical production ranging from 2000 to 4000(7,500 to 15,000 liters).
The flow rate through the filter will decrease with time until there is no more flow. When the flow decreases, it is possible that the cartridge is saturated. In this instance, it is possible to brush the exterior surface of the cartridge in order to eliminate any obvious large impurities. If the flow still does not increase, simply replace the NANOCARB cartridge.
The actual flow rate through
the cartridge will depend on available water pressure. Typical flow rates
for NANOCARB cartridges based on an
inlet water pressure of 58 PSI (4 bar) are as follows :
Based on current performance results over many years in Europe and in Canada, we can easily summarize that a NANOCARB filter will last more than one year under normal household usage. Replacement of the filter cartridge takes less than five minutes.

As the name implies, NANOCARB achieves both 0.45 micron filtration with 0.003 micron adsorption, which removes almost all particulate from water, while leaving essential trace minerals in the water supply. Contaminants such as chlorine, color, lead, tannin, limestone particles, iron, manganese, chlorides, pesticides, herbicides, and all bacterial, viral and spore types are eliminated once the source water has passed through a NANOCARB filter. Your can view our Lab Test Page for more information.
No. Simply speaking, NANOCARB filtration will only slightly reduce hardness in water. This is because the filter removes the particulate hardness (the building blocks of scale formation) and all other physical elements but not the ionic hardness. Although a test for hardness will show a reduction, the remaining hardness will not be able to produce hardness scale formations.
There is a simple answer such as Yes, everyone should have a NANOCARB filter for all water consumption, regardless of good or bad water, but simply as a safe barrier between your water consumption and the water supply itself. No one can be too careful and just by having water go through a NANOCARB filter is definitely the right thing to do.
The other answer is more complicated and would depend on your water analysis. There would be one exception and that is, if your water has high Total Dissolved Solids (TDS), which are really at their ionic size, like sodium, calcium, chlorides and carbonates, then you would have to use a Reverse Osmosis (RO) unit first and put a NANOCARB filter where the RO units' current cheaper powdered carbon filter is located. This will ensure no contamination can come from the reverse osmosis holding tank. RO units are very demanding to maintain and neglect often results in worse water than the regular water itself, so you have to be vigilant with RO.
if your water is above these levels. It simply means your NanoCarb filter
will work but the service life would be lower than anticipated.
Some of the obvious uses for NANOCARB include:
Although Reverse Osmosis offers the best filtration in terms of pore size at 0.001 micron range, NANOCARB filters provide the best alternative for end users who do not really require the use of Reverse Osmosis to obtain purified water. We do not want to state that this is an absolute observation, but in situations where the TDS level is not of major concern, NANOCARB provides a very very good alternative with added advantages, most important of which is the fact that it does not waste water.
For areas where water conservation is of prime importance, NANOCARB will provide the best filtration/adsorption possible without wasting water.
