:201 Shower Filters

Welcome to today’s 1:5:10:365 Tip for becoming a better steward for our home and planet environment.

1:5:10:201 EcoTip: Shower filters with KDF (kinetic degradation fluxation) are good for chlorine removal since they work better with hot water. Activated carbon works better for cold water.

KDF is a zinc and copper alloy that reacts with chlorine transforming it into a chloride salt. The zinc and copper alloy metal helps control bacteria growth and can remove some heavy metals. Since KDF works well at higher temperatures, it outperforms other purification measures for shower and bath water, but the range of contaminants removed is somewhat limited.

:192 Carbon Water Filtration

Welcome to today’s 1:5:10:365 Tip for becoming a better steward for our home and planet environment.

1:5:10:192 EcoTip: Activated carbon in drinking water filters can help to remove chlorine and other volatile organic compounds. The length of time it takes the water to pass through the filter determines the amount of chemical that gets removed. The slower the water flow the greater the removal.

Be careful when interpreting the quality of a water purifier based on manufacturer’s claims. I was once asked to evaluate a purifier based on test results showing a 99% removal of chlorine. The problem was the manufacturer’s instructions said to install the filter so that it would deliver 1 gallon per minute, but the test was performed with the water being passed through the filter at a rate of 0.1 gallon per minute (ten times slower). The advertised test results were of course much better than what was being delivered to the client’s glass. To get the better results the client needed to slow the rate of filtration down to the test rate.

Chlorine removal performance is easy to test – you can visit any aquarium shop that sells tropical fish and purchase a sensitive chlorine test kit. 

If you want to compare chemical removal efficiency between purifiers before you purchase one, make sure the testing has been performed in compliance with National Sanitation Foundation standards. This will help make sure you are comparing units that have been tested in a consistent way.

Welcome to today’s 1:5:10:365 Tip for becoming a better steward for our home and planet.

1:5:10:136 EcoTip: U.S. Tax Rebates are arriving in the mail. The government would like us to spend our way out of the recession. If your going to spend the money – why not spend it green? If you spend it for many of the energy saving upgrades discussed in these 1:5:10:365 EcoTips you should consider it a money saving investment with a carbon payback as well.
