The TALLboy unit is designed to be a stand alone filter for immediate removal of chlorine and sediment from your water. It is rated at up to 99% chlorine removal @ 2 GPM flow and can clean up to 90% of the sediment particles above 5 microns. This filter is not designed to significantly lower the Parts Per Million (PPM) of your water. The majority of PPM is minerals which can only be removed with Reverse Osmosis.

Having chlorine and sediment free water is essential to growing healthy plants and maintaining beneficial micro-organisms, bacteria and fungi in your root zone and growing medium. Beneficial microbes can not survive in the presence of chlorine. Chlorine free water is also essential for organic compost tea and extraction solution brewing, hydroponics and any bio-organic gardening method.


The TALLboy instantly de-chlorinates your water at fast flow rates of 120 gallons per hour. Don't give your prized plants straight hose water. Keep your beneficial micro-organisms alive and thriving.
