This is a high quality SimPure water filter, suitable to filter water in most standard big filter housings which have an inner diameter of 4.5 inches and an inner height of 20 inches. This filter is filled with premium sintered coconut shell carbon, designed to vastly improve the taste and quality of water in your home and to filter out countless components of it which are unsafe and/or undesirable. This SimPure model has been tested against NSF/ANSI standard requirements and has successfully been certified after it's tests, proving it's functionality and effectiveness. This listing is for a single SimPure CTO-F20B-5 filter which is factory sealed in a plastic wrapping with original packaging and sticker present underneath, and is prepared to use to protect your home's water supply from contaminants! I have never used this item, and it has not been removed from it's pictured packaging or condition.
