Our products remove or reduce more drinking water contaminants than the leading filtration brands.

Through rigorous testing by independent, certified laboratory, Envirotek Laboratories, our products have been proven to effectively remove or reduce hundreds of contaminants from water. Compare the ability of Auro’s products to any of the leading brands, and you will see why Auro is the manufacturer who provides the most comprehensive solution for water treatment.

Our products effectively remove or reduce the following drinking water contaminants:

Agricultural Chemicals
Disinfectants & Disinfection Byproducts
Heavy Metals
Industrial Chemicals
Pharmaceuticals & Basic Drugs


Our products are better for you and better for the environment.

Water pollution is one of the world’s biggest problems. Not only does contaminated water damage our health, but it damages the health of our environment as well, killing plant and animal life and damaging ecosystems. Auro provides a solution that will benefit all living things as our products can be used to clean any freshwater source; whether from your tap, well, lake or pond.

By cleaning water, Auro’s products help clean the air. Certain chemicals, like Volatile Organic Comounds (VOC’s), easily evaporate from water and end up in the atmosphere. By reducing these chemicals in water, Auro’s products help reduce them in the air as well.

Auro’s products help reduce greenhouse gases and landfill waste by eliminating the need for bottled water; so you can get pure, fresh water without all the waste. Talk about refreshing!

Our products improve the taste of water

Taste is one of the main reasons people choose to filter their water. Unlike other filtration brands that only reduce 97% of chlorine, Auro’s products remove 100% of chlorine, completely eliminating any nasty pool water taste. Auro Water Purifying Solution naturally contains trace minerals which help give your water a crisp, refreshing taste.

Our products are 100% natural.

Auro Water Purifying Solution is a blend of purified water and naturally occurring ionic sulfate mineral salts that purifies water without the use of toxic synthetic chemicals.

Select Committee on GRAS Substances (SCOGS) Opinion: Ferric Sulfate (FDA)

Quotes taken from the above resource:

“Iron deficiency is a leading nutritional problem in the United States. Intakes of iron are below recommended levels for a large fraction of the population. hence, it is evident that an increase in iron fortification of selected foods could be an important public health measure. The form of iron utilized to fortify foods should be of adequate bioavailability.”

“Certain compounds have been employed extensively for many years both as additions to food and in the treatment of iron deficiency with no reported adverse effects.”

This report is filled with excellent and useful information regarding the role iron plays in drinking-water, please review it in it’s entirety.

Aluminum Sulfate: What is Aluminum Sulfate? (Wikipedia.org)

Select Committee on GRAS Substances (SCOGS) Opinion: Aluminum Sulfate (FDA)

Quotes taken from from the above resource:

“Aluminum and its salts are found in varying amounts in nearly all foods. In addition to the aluminum occurring naturally in foods, man can be exposed to the aluminum added to foods, to that in aluminum antacids he may take, and to that from aluminum cooking vessels. It has been estimated that the daily aluminum intake for man from all dietary sources can range from 10 to 100 mg per day and that of this amount, the intake from aluminum compounds added to food may average about 20 mg per day, about 75 percent of which is in the form of sodium aluminum phosphate. In relation to body weight, these amounts are less than those needed to produce toxic responses in experimental animals.”

“But the nature of the inorganic compounds at least does not suggest that, ingested in such small amounts, they would have a different effect than the other aluminum compounds considered in this report, all of which exhibit low orders of toxicity.”

“In the light of the foregoing, the Select Committee concludes that: 1.) There is no evidence in the available information on aluminum ammonium sulfate, aluminum potassium sulfate, aluminum sodium sulfate, aluminum sulfate, acidic sodium aluminum phosphate, basic sodium aluminum phosphate, and aluminum hydroxide that demonstrates, or suggests reasonable grounds to suspect, a hazard to the public when they are used at levels that are now current or that might reasonably be expected in the future.”

Quote taken from the above response:

“In regards to Aluminum Sulfate this is a component of Mica which we have clearly listed on the product label. The Aluminum Sulfate is not an issue for several reasons: a)it is a very very small trace amount but more importantly b) we did not base a claim off of aluminum sulfate and black mica has been reviewed for safety and deemed just fine and henceforth aluminum sulfate is the same…in a comparison there is ascorbic acid in vitamin c but no one makes a safety complaint on ascorbic acid if Vitamin C in full has been deemed safe…make sense?”

On page 161 the third paragraph is particularly interesting. It speaks of a study that showed no association between aluminum in drinking-water and Alzheimer disease, however there WAS an association between ORGANIC monomeric aluminum and Alzheimer disease.
