Give your plants the cleanest water possible. The GROW1 Inline KDF-85 Garden Water Filter removes chloramine, chlorine, and heavy metals directly at the source — protecting your root zone, preserving beneficial microbes, and delivering purer water with every watering cycle. Whether you're running a hydroponic system, irrigating a greenhouse, or feeding an outdoor garden, this filter is built to perform where it matters most.
Why GROW1 Inline KDF-85 Garden Water Filter
The KDF-85 media is specifically engineered to target chloramine and heavy metals — contaminants that standard carbon filters often miss. Unlike basic sediment filters, the KDF-85 process media uses a redox (oxidation-reduction) reaction to convert harmful compounds into harmless ones, without releasing byproducts into your water supply. GROW1 has packaged this proven technology into a compact, inline form factor that installs in seconds on any standard garden hose or irrigation line.
Growers choose the GROW1 KDF-85 because it delivers consistent filtration performance across a wide range of water temperatures and flow rates — making it equally effective for cold-water drip systems and warm greenhouse environments. It's a low-maintenance, high-impact upgrade for any serious grow operation.
Key Benefits
- Chloramine & Chlorine Removal – Eliminates disinfectants that kill beneficial microbes and disrupt nutrient uptake.
- Heavy Metal Reduction – Reduces lead, mercury, iron, and hydrogen sulfide for cleaner, safer water.
- Protects Beneficial Microbes – Preserves the living biology in your root zone and growing media.
- Universal Inline Design – Connects directly to any standard garden hose or irrigation line — no tools required.
- Wide Temperature Range – KDF-85 media performs effectively in both cold and warm water conditions.
- Long Filter Life – Designed for extended use across full growing seasons before replacement is needed.
- Compact & Lightweight – Easy to install, move, and store between grows.
Use Cases
- Hydroponic & DWC Systems – Filter source water before it enters your reservoir to protect nutrient solutions and root health.
- Drip Irrigation – Inline installation prevents chloramine buildup in emitters and tubing over time.
- Greenhouse Watering – Deliver clean water to sensitive seedlings and transplants without chemical interference.
- Outdoor Garden Hose Use – Attach directly to your hose bib for filtered water across raised beds and container gardens.
- Living Soil & Organic Grows – Essential for growers using compost teas, mycorrhizae, or beneficial bacteria that are sensitive to chloramine.
- Cannabis Cultivation – Supports optimal terpene and cannabinoid development by removing water contaminants that stress plants.
Directions for Use
- Thread the inlet end of the KDF-85 filter onto your garden hose, hose bib, or irrigation line.
- Connect your watering wand, drip line, or irrigation tubing to the outlet end.
- Turn on water and allow a brief flush (30–60 seconds) before first use to prime the filter media.
- Use inline throughout your watering cycle — no bypass needed.
- Monitor flow rate over time; a significant drop in pressure indicates the filter media is nearing capacity.
- Replace filter cartridge or unit per manufacturer guidelines based on water quality and usage volume.
Ingredients / Guaranteed Analysis
- KDF-85 Process Media – High-purity copper-zinc granules engineered for heavy metal and chloramine reduction.
- Derived From: Copper and zinc alloy (KDF Fluid Treatment, Inc. process media).
- NSF-tested media; no chemical additives or secondary contaminants introduced during filtration.

Frequently Asked Questions
What contaminants does the KDF-85 filter remove?
The KDF-85 media is specifically effective at reducing chloramine, chlorine, hydrogen sulfide, iron, lead, mercury, and other heavy metals commonly found in municipal tap water.
Is this filter compatible with my existing hose or irrigation setup?
Yes. The GROW1 KDF-85 uses standard garden hose threading and connects inline with most drip systems, hose bibs, and irrigation lines without adapters.
How long does the filter last?
Filter life depends on your water quality and usage volume. In typical home or small commercial grow applications, the filter is designed to last through one or more full growing seasons. High-chloramine municipal water will reduce filter life faster.
Can I use this filter with hot water?
KDF-85 media performs across a wide temperature range, but it is optimized for cold to warm water (not boiling). It is suitable for most greenhouse and outdoor irrigation applications.
Does this filter remove nutrients or pH-adjusting compounds?
No. The KDF-85 targets specific heavy metals and disinfectants only. It will not strip nutrients, alter pH significantly, or interfere with your nutrient solution.
How do I know when to replace the filter?
A noticeable drop in water flow rate or pressure is the most common indicator that the filter media is saturated and needs replacement. You can also test your filtered water periodically with a chlorine test kit.
