Which is better? Corvega or a bottled water purifying device?
The American Water Works Association, a trade group, says Corvegas purifying devices have “excellent water filtration capabilities.”
The American Chemistry Council says they “purify water well and can effectively clean tap water, so the product is ideal for use in water purification.”
Both organizations recommend water purifiers for water treatment.
But it’s not clear if any of the manufacturers in the industry recommend the same water purifications for the general public.
The Association of Water Purifiers, an industry group, said it has “a long-standing and successful relationship with Corvegas and Coca-Cola, and is very proud to have them on board.”
Coca-Colas, which owns Coca-Mart, said the company “supports the water purify program” and that the product has “been a highly effective and trusted water puritizer for many years.”
Coke declined to comment on which manufacturers were recommending which purifiers, saying “there is no data to support any particular recommendation.”
Water purifiers aren’t cheap: Coca-colas said the devices were made in China.
And many purifiers are made by foreign companies.
The AAPI says some purifiers cost $200 to $300, while others can be as cheap as $25.
The companies that make them also claim they provide “an excellent water purifcation experience.”
But consumer groups say they don’t like the devices because they don: The devices are “not water-efficient,” they say, because they can’t clean tap waters that have a pH of more than 5.0, and they can only purify water that is not safe for drinking.
Some water purifi- cators are also expensive.
The Aquarius Eco-Pure Aqua purifier from Aquarius sells for $3,500.
The Bio-Max Aqua purification system from Aquastar costs $1,500 and includes an optional carbon filter.
The AquaSpirator Water Purifier costs $8,200, while the BioMax Eco-Purifier costs around $7,000.
The Avanti Eco-Clean Water Purifying System sells for about $5,000 and includes a carbon filter, a plastic filter and a CO2 filter.
According to the AAPI, the water-purification devices can be expensive because they are made of a “non-reactive, lightweight, flexible material” and they have “low thermal conductivity and limited filtricity.”
The company also makes a device that is “similar to the AquaSparrow, but in an even lighter and smaller form factor,” the AAPC said.
The company says that the Aquastars eco-clean technology has a “comparatively low cost of manufacture.”
The AAPC says the company’s “a few hundred million dollars in manufacturing and testing costs” were covered by a federal grant that was awarded to the company last year.
It says the money was for the “purchase of materials” and “engineering” that “provide advanced manufacturing capabilities.”
However, the AAPCI says the project “has not been fully developed” and there are still “significant technical issues that need to be resolved.”
The manufacturer of the AquaScout said it was unaware of the AAPT’s findings.
It added that “the AquaScouts product meets the standards of the EPA and has been thoroughly tested in the field.”
Coca Colas also has an AquaScouter that is similar to the BioMAX.
A spokeswoman for Coca-Pepsi USA, which also owns the Aqua Scout, said she “did not know” whether the company had “specific knowledge of the safety of the BioScout.”
Pepsi said it “has never used the Aquascout technology.”
“While we understand the AAPB’s concerns, we believe that the technology is well-established and is safe,” she said.
A Pepsi spokeswoman said the product “is available in the U.S. and has an EPA seal of approval.”
But the AquaScanner from the water company was not sold to consumers, so its safety was not investigated.
A Coca- Colas spokesperson said the Aqua Scanner “is a new technology that has been developed by PepsiCo.”
