We mentioned this filter (the Pentek ChlorPlus) in the past and now feel the need to mention it again since we continue to receive inquiries from people asking why their water filters fail to remove all of the chlorine smell from their water.

The majority of water filters readily available in the marketplace do NOT remove chloramines, also known as combined chlorine. Most carbon filters remove free chlorine only. It takes a specialized type of filter like the Pentek ChlorPlus to cleanse water of unwanted chloramines.

Does my water contain chloramines?

Whether your municipal water system uses free chlorine or chloramines as its primary sanitizing agent we cannot say, but in either case your water will certainly contain chloramines. Unsure why? Take a look at this brief tutorial on free chlorine, total chlorine and combined chlorine.

That’s just a cartridge… What sort of housing does it go in?

A very keen observation followed by a very good question! The Pentek ChlorPlus filter for chloramine removal fits in most standard sized 10″ (by 2.5″) filter housings available from online retailers like Filter Water..

As always before purchasing a replacement cartridge for your water filter system, check, double check and TRIPLE check to make sure your housing will accommodate the filter cartridge you wish to buy!

Chloramines? What are chloramines? Take a look at this earlier Water Testing Blog entry on Free Chlorine, Combined Chlorine and Total Chlorine and get a quick education on the topic!

Whether created as a byproduct of disinfection via free chlorine or the intended disinfectant in a water system, most people do NOT like the taste and odor of chloramines in their water.

Thankfully Pentek has come out with a product called the Pentek ChlorPlus 10 Chloramine Removal Water Filter Cartridge that fits in standard 10″ (x 2.5″) filter housings used in filter sytems produced by companies such as Pentek (obviously!), US Filter (recently acquired by Pentek!), Cuno, Filterite, Keystone, US Water, Water Resources, Harmsco, and many other popular brands of water filtration systems. If your system uses a standard 10″ x 2.5″ housing, the Pentek ChlorPlus 10 ought to fit just fine!

Having said that last bit, please check the dimensions of your current filter and/or housing before ordering this product!
