Multi-Pure Chosen As The Best Filter!

Multi-Pure's "Aquadome"

A comparison/analysis was recently conducted for Engr308 Technology and the Environment, at Humboldt State University by: Bryan Thomson, Dana Martin, Kristi Morton and Kristy Method. The class project's goal was to determine which drinking water system is the best for Arcata, Humboldt County, California residents, or anyone else, who wants to make the least impact on their wallet and the environment while receiving the healthiest water possible.

Their project compares water filtration systems by Multi-Pure and Brita. They compared the two types of water filtration systems on financial cost, CO2 released in transport and contaminants released into a person. Brita and Multi-Pure filtering systems both offer similar technology to filter the water, but what does it take for those filters to make it to a consumer's home?

In their research they used the standard that a household will have four people in it, that the flow of water will stay constant and no additional contaminants will be introduced into the system other than what their data supplied by Humboldt Municipal Water District provided.

Brita provided basic information, through a phone interview, on where and how their filtering system is produced and shipped. The class also considered what the filter is made of, how many gallons it filters before replacement is recommended; and any other relevant information. Multi-Pure provided similar data and information about its product as Brita, yet more personal and in depth and offered additional insight that Brita wouldn't comment on.

The results they found are fairly conclusive. Multi-Pure is the best!

When comparing costs, the Multi-Pure system costs $224.95 and each filter costs $56.95. So over a 5 year period, you would spend ~$509.70 (not including tax and shipping). The Brita system costs $49.99 and each filter costs $29.99, of which you will need ~4 filters/year. So over a 5 year period, you would spend ~$649.79 (not including tax and shipping).

When comparing impurities that are filtered out, Multi-Pure filters out 64 contaminants and Brita filters only 5. Over a five year period the Multi-Pure would emit ~995 Kg CO2; and for Brita, if you recycle every filter, you would emit ~4120 Kg CO2; and if you don't recycle any of the filters, you would emit ~3170 Kg CO2 (based on 4 filters/year). This does not take into consideration the benefits of recycling and the impacts of landfilling.
