Filtered Water for Home Beer Brewing

When brewing beer with tap or bottled water, chlorine and chloramine present in the water can combine with malt phenols in the wort to create a compound called chlorophenol, which can give the beer a medicinal taste.

Bottled Water Cost Calculator

Bottled water requires a lot of resources to manufacture and ship, and costs a lot more than reverse osmosis water.

Use our Bottled Water Cost Calculator to find out how much of an impact you have on the environment.

Contaminants Removed by Reverse Osmosis

Reverse osmosis systems can remove contaminants that are unhealthy and possibly deadly through a combination of granular activated carbon, carbon block & sediment filtration, and thin film membranes.

Drinking Water Contaminants

As our technology advances, so do new forms of pollution and contaminants that effect our environment and our health.

Read more about drinking water contaminants and their health effects.

Chlorine and Its Effects

Chlorine has long been recognized as an oxidative agent, meaning that it not only kills the germs in the water supply; it will damage any living tissue with which it comes in contact. And your skin, like the rest of your organs, is living tissue. But that’s not the only problem.

Fluoride and Its Effects

Since the discovery of its health benefits in the mid-1940's, fluoride is often added to the public water supplies of industrialized countries in order to reduce the populations tooth decay, which is especially effective in low income communities, where good dental hygiene may be too costly.

Hard Water FAQ

Hard water is the most common problem found in the average home. Hard water is water that contains dissolved hardness minerals above 1 GPG, such as calcium, magnesium and lime.

Water softening fixes this problem without adding any chemicals into your water supply.

Benefits of Water Softening

Hard water is not as efficient as soft water for bathing, washing dishes, clothes, car & many other uses.

Water Bottle Pollution

Bottled vs Tap Water

Bottled water advertising leads people to believe that their products are produced in pristine, natural surroundings and are purer. The truth is most bottled water is just filtered tap water.

H2O Water Bottle

Bottled water works out to paying 5 cents per ounce for a 20 ounce bottle costing $1. In comparison, tap water costs less than 1 cent per gallon. The average price of gas in the United States is around $3 a gallon, or 2 cents an ounce, so you are paying over twice as much for bottled water by volume as you are for gasoline.
