Now lets look at the Coconut Carbon in Nova Filters

Carbons are made from different raw materials possessing vastly different pore size ranges and iodine ratings, which lend themselves toward certain applications. Carbon can be made in many different ways and each type is best suited to a different application. Over the years Nova tested and developed the highest-grade coconut carbon used initially in our aquarium stores over 20 years ago. The results with delicate marine & tropical fish were obvious they were thriving in this purified water.

Carbon is very effective at removing many contaminants, including the following:

• Residual chlorine and monochloramine
• Taste and odor causing organic contaminants
• Volatile organic compounds (VOCs)
• Trihalomethanes (TTHMs) and other halocarbons
• Endocrine disrupting compounds (pharmaceuticals, personal care products, etc.)
• Chloramine, hydrogen sulfide and hydrogen peroxide (removed by catalytic carbons)

Carbon must not be the sediment filter, it is best for it to act only as an adsorbent for dissolved organics, not the filtration of solids. When a system doesn't pre-filter sediments the carbon gets coated with the sediment in so doing there is no longer direct contact of the carbon and water without contact it will not work effectually.
Therefore, small single carbon filters or canisters just don't work efficiently they get clogged up with sediment then the carbon gets coated with sediment.

We use two sediments in the Nova Whole House filter before our carbon.
Carbon has a finite use based on gallons of water passing thru it. All carbons can only absorb so many contaminants before losing it’s effectiveness and its adsorption efficiency. This happens when the pore structure of the carbon is so full that it cannot adsorb any more impurities. At 26,000 gallons, the Nova Carbon is typically deemed spent, and would need to be replaced.

We recommend carbon remain in drinking water filtration system for more than 12 months. Interesting to note that carbon left unchanged in aquariums will have a detrimental effect on live aquaria due to loss of its effectiveness.

There is more than one company selling carbon tank filters claiming they will last 5 years I cringe when I see this here’s why.

Carbon filters in water filters have a limited ability to adsorb contaminants from water, and so the carbon filter in water purifiers should be changed when it has been depleted and cannot purify water anymore.

At this stage the carbon will start rejecting some of the previously adsorbed pollutants back into the water flowing over it. This is called ‘breakthrough’. When this happens, the concentration of pollutants in the treated water will be higher than in the raw water being treated.

We use the best activated coconut hay carbon in our Nova water purification system this proprietary aquarium grade carbon has the highest iodine rating available is the microporous type and they are best for removal of chlorine and it's by-products called TTHM's and volatile organic compounds or VOCs in water. We have test results from an independent laboratory taken from homes in The Villages Fl. that clearly demonstrate this.

Nova high grade carbon in not available anywhere online or in retail stores except from us, there are lesser quality charcoal carbons on the market perhaps at a lower cost but why not have the best for the heath and wellbeing of you and your family.

Chemicals Taste & Odor

Most harmful chemicals are removed from the water when it is treated in the public water treatment system. However, chlorine is one common chemical that remains. In fact, chlorine is added to the water supply to act as a disinfectant. However, once it has killed any viruses and bacteria, it doesn’t need to stay in your drinking water. Chlorine gives water a bleach-like taste and aroma. Additionally, long-term consumption of chlorine can have negative effects on your health.
