Each GreenSaver product comes with an enhanced carbon filter. Enhanced carbon is a mixture of activated carbon and potassium permanganate, which work together to remove all of the ethylene gas your produce gives off. The activated carbon absorbs the ethylene gas the way a sponge absorbs water, and traps and holds ethylene gas in tiny nooks and crannies. The potassium permanganate grabs any leftover ethylene gas, and oxidizes it. This way, fruits and vegetables don’t reabsorb the ethylene gas, and your produce stays fresh longer.

After 90 days, all of the available space to absorb ethylene gas will be filled up, and the filter needs to be replaced.

Don’t worry – we won’t. Enter your information below and every three months we’ll send an email reminder 10 days before your filter should be replaced. That way you can rest easy and your system won’t miss a beat (or beet!).
