GreenGro KDF Carbon Water Filter | Chlorine + Heavy Metal Hose Filter, 5/8 in

What the GreenGro KDF Carbon Water Filter Takes Out

The filter is a hose-end canister with two media inside it. KDF is a copper and zinc alloy that works by a redox reaction as water passes over it. It pulls chlorine out and binds heavy metals such as lead. KDF also keeps bacteria from growing inside the canister while it sits idle, so it stays clean between uses. The activated carbon is the second stage. Carbon takes the gases, oils, debris and chemicals that KDF leaves, the volatile organic pollutants that give tap water a taste and a smell. Together they hand the plant water that has lost its disinfectant and its metals but kept its minerals. That is what a living soil wants. Chlorine is in the tap to kill microbes. It does not know the difference between a pathogen in a pipe and the bacteria a grower has spent a season building in a pot. Filtered water also spares roots the chemical burn that aggressive municipal water can leave on a young plant. GreenGro makes the filter in the USA with large-capacity media. The housing is built to stand up to hard water flow and long exposure to sun. It threads onto any standard 5/8 in water or garden hose at either end. It sits between the tap and the hose or between the hose and the wand. It suits the garden first and then RVs, hot tubs, boats, pools, spas, ponds and campers. The filter weighs about a pound and arrives ready to thread on.

Running a Garden Hose Water Filter for Living Soil and Compost Tea

A garden hose water filter earns its place on the day the first compost tea is brewed. A tea watered in with chlorinated water loses much of what it was made for. Flush the filter for a minute before the first use to clear any loose carbon fines. Run it to waste until the water comes out clear. Keep the flow moderate rather than full bore. Media needs contact time with the water, and a hose opened full bore pushes water past the KDF faster than the reaction can work. A wand or a watering nozzle on the downstream end does that throttling on its own. Put the filter on the tap end of the hose rather than the nozzle end where it can. Then the whole hose carries filtered water and the canister is not dragged around the yard. Take it off before the first freeze. Water trapped in the housing expands, and a cracked canister is the end of the filter. Store it out of direct sun between seasons, since light through the housing grows algae on the media. Rinse the threads and the housing when the hose is put away, and check the washer at each end for a nick. A filter that drips at the thread is losing pressure the plants could have had. Replace it when the flow drops noticeably or when a glass of water from the hose starts to taste of the tap again. Those two signs arrive before any other, and both mean the media has given what it had.
