About Water Filtration Systems

PUROTwist makes high quality water filtration systems using Omnipure's exclusive Twist Tap filters. This type of water filtration system is used to improve drinking water taste and depending on the type of filter selected can remove chlorine and lead.

Q. What is Water Filtration?

A. A process in which water passes through a water system that may include one or more filters for the purpose of removing turbidity, taste, color, iron or odor and certain chemicals such as chlorine. The design can be loose media tank-type systems or cartridge devices. In general the process may include mechanical, adsorptive, neutralizing and catalyst/oxidizing filters.

Q. What is activeated carbon and what does it do?

A. Carbon used in filtration applications is produced by grinding a carbon source - like bituminous coal, peat or coconut shells and heating the material in the absence of oxygen to 1000 degrees to bake off impurities. The material is then subjected to 1600-degree steam to “activate” the carbon. The steam leaves carbon granules filled with cracks and pores, enabling them to store large amounts of chemicals. One pound of activated carbon (the amount in a standard ten-inch filter cartridge) has the equivalent surface area of a 160 acre farm. Carbon removes contaminants in two ways: through adsorption , contaminants are attracted to the surface of the activated carbon and held to it in much the same way a magnet attracts and holds iron filings; and by acting as a catalyst to change the chemical composition of some contaminants. Activated carbon is ideal for removing chlorine, organic chemicals such as many kinds of pesticides, THMs like chloroform and many VOCs that are components of gasoline, solvents and industrial cleaners.

Q. There is chlorine in my water. Is chlorine bad for me?

A. Chlorine in itself does not appear to be a problem other than the aesthetic concerns of undesirable taste and odor it creates. There has been a lot of research on the effects of chlorine with evidence showing that the biggest concern being its reaction with natural organic materials like leaves and humus forming disinfection by-products, which are considered carcinogens. Installing a point of use water treatment system that incorporates the use of carbon filtration can be very effective in correcting this problem.
