Why tap water is hard on houseplants.
Chlorine & chloramine
Both stress plant roots and the soil microbes your plants rely on. Chloramine - used by many cities - does not off-gas when water sits out overnight.
Fluoride
Builds up in the leaf tips of sensitive plants like calathea, spider plant, dracaena and peace lily, causing the classic brown, crispy tips.
Heavy metals & salts
Lead, arsenic and mercury accumulate in soil along with dissolved salts, leaving white crust on the soil surface and steadily weaker growth.
Fill, pour, done.
1. Fill from the tap
Tap water drains through the multi-stage filter into the can below.
2. Pour
The water in the can is already filtered and remineralized, so you pour clean water.
3. Remineralized
Natural mineral media, tourmaline and Maifan stones add back calcium, magnesium, potassium, iron, zinc and trace minerals.

Distilled and reverse-osmosis water contain almost no minerals. Letting tap water sit removes some chlorine only - not chloramine or fluoride.

What we filter out.
Chlorine & chloramine
Lowers stress on plant roots and soil microorganisms.
Heavy metals
Lead, aluminum, arsenic, cadmium, mercury, chromium, and tin.
Fluoride
Helps avoid inhibited nutrient uptake at the root.
Volatile Organic Compounds (VOCs)
Preserves healthy soil biology.
Pesticides & herbicides
Reduces damage to plants and beneficial microbes.
Trihalomethanes (THMs)
Reduces byproducts formed during municipal water treatment.
Bacteria, viruses & pathogens
Filters out certain harmful microbes from your tap water.
Colloids
Reduces turbidity, preventing soil clogging and drainage issues.
What we add back.
Natural mineral media
Helps balance soil moisture, aeration, and nutrient retention.
Calcium
Supports strong cell walls and overall plant structure.
Magnesium & iron
Aid chlorophyll production, photosynthesis, and leaf color.
Potassium
Supports water regulation and nutrient transport.
Zinc
Supports enzyme function and growth regulation.
Selenium
Supports plant metabolic processes.
Trace minerals & elements
Restores minerals removed during the filtration process.
Plants that notice the difference.
Calathea & prayer plants
Spider plant
Dracaena & corn plant
Peace lily
Ferns
Palms
Orchids
Better water, tonight's watering.
