It Matters and Each Sip use activated carbon

Organic compounds that pollute your drinking water are hydrophobic, meaning they don’t bind to water at the molecular level. They do, however, bind to the non-polar carbon molecules inside an activated carbon filter, allowing your water filter to pull pollutants from the water as it passes through the carbon. 


Indeed, we have the coconuts. Both the It Matters and Each Sip brands are activated carbon filters built from carbon within coconut shells, which feature a high density of very small pores. This allows for more effective and efficient filtration than the dated competitors of coal-based and wood-based activated carbon filters, both of which have larger pores. 

Our filters deliver great tasting water

Coconut shell activated carbon also produces better tasting water than other forms of activated carbon filters. Coal-based activated carbon can release byproducts into the water during filtering, which can hurt the taste of the water. Coconut shells are extremely low on taste affecting particles like inorganic ash.

What they catch

It Matters, our premier brand of fridge filters, is effective against both health contaminants and those that affect the taste and appearance of your water. It Matters will filter, on average, more than 98% of lead, more than 94% of chlorine taste and odor, more than 98% of asbestos, and a whole host of other contaminants common in drinking water. 

Environmentally friendly

Unlike other sources of activated carbon, coconut shells are renewable. Coal-based carbon requires destructive mining operations, and wood-based carbon comes from trees that we’d prefer to keep standing. Coconuts can be harvested 3 to 4 times throughout the year and don’t require destruction of our environment to do so.
