1. If a filter can take out Chlorine, can it also take out Trihalomethanes (disinfection by-products)

Multipure Drinking Water Systems has been tested and certified to reduce chlorine and trihalomethanes. However, not all filters certified to reduce chlorine can reduce trihalomethanes (although some disreputable would have you believe so!) Chlorine is a substance that is relatively easy to treat. But, chlorine that has intereacted with organic materials to form trihalomethanes (thus having a totally different molecular structrue) is difficult to remove. Consumers must check with NSF to see if a non-Multipure filter is certified for trihalomethanes and VOCs reduction.

2. Can hot water be run through the filter?

The biggest problem with hot water is the sloughing off of chemicals/compounds which had been adsorbed to the filter surface. Heat causes the carbon pores to open up, reducing the filtering effectiveness, and resulting in lead or chemicals being released into the water.  This performance degradation occurs even though hot water is usually below 212 degrees farenheit, and therefore not hot enough to alter the raw materials or cause to the filter itself.  If someone does run hot water through the filter, immediately run cold water through the filter for at least 3 minues, to cool and flush its contents.  Do not drink hot water passed through the filter. 

3. Do the Multipure Solid Carbon Block Filter reduce Fluoride?

Multipure's Aquaversa, Aquadome and Aquamini are not certified for Fluoride reduction. There are many filters on the market which claim to be able to remove fluoride from water, however Multipure has been unable to replicate or verify the performance claims of those filters & filter media. Reverse Osmosis & Distillation remain the only bona fide treatment technologies for the long term treatment of Fluoride at the point-of-use. Fluoride can appear in water supplies due to both manmade & natural sources.
