Tivano Pro FreshShield

A rinse gets the dirt, not the wax or the pesticide residue underneath. FreshShield is a capsule smaller than a soda can: drop it in a bowl of tap water with your produce, press once, and a weak current turns the water itself into the cleaner. Ten minutes later it beeps and stops, with nothing added and nothing to rinse off.

There's nothing to buy again, ever: no sprays, vinegar, filters, or cartridges. It works in any bowl or sink you already own, and owners report that berries and greens stay fresher for longer.

The bowl comes out visibly cleaner, and rinsing produce turns from a guess into something you trust.
