Refrigerator Filtered Water for Carnivorous Plants: Useless – Use Distilled or RO

Fridge filter (carbon) + 2-day standing = **no mineral removal**. Carbon filters don't reduce TDS. Standing water does nothing.

Only Effective Methods

• Distillation
• Reverse Osmosis (RO)
• Deionization (DI)

Practical Advice

• RO units = most economical long-term.
• Grocery store distilled refill stations = cheapest short-term.
• Test your tap water – if <50 ppm TDS, it's usable straight.

Fridge filters improve taste, not purity for plants.
