Filtered, mineral-rich water for your houseplants. Poured from a watering can.
Pearl Roots is a watering can with a built-in multi-stage filter. Fill it from the tap; it removes chlorine, chloramine, fluoride and heavy metals as you pour, then adds back 20+ minerals your plants need.

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
No jugs, no bottles, no plumbing. Just fill the can like any other watering can.
2. Pour
The multi-stage filter removes chlorine, chloramine, fluoride and heavy metals as the water flows through.
3. Remineralized
Zeolite, tourmaline and Maifan stones add back calcium, magnesium, potassium, iron, zinc and trace minerals.

Distilled and reverse-osmosis water remove contaminants but strip minerals too and add none back. Letting tap water sit removes some chlorine only - not chloramine or fluoride. RO systems need installation.
Filters and remineralizes.
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.
Zeolite
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
Carnivorous plants
