Double Krisp

Your refrigerator has two crisper drawers. Now both of them work.

Most households split their produce across both drawers — high humidity for leafy greens, low humidity for fruit. Ethylene, the ripening gas fruit gives off as it matures, builds up in both. In a closed drawer it has nowhere to go, and everything sensitive to it ages faster than it should.

The Double Krisp is two ethylene-absorbing casings, one for each drawer. Peel, stick it to the side wall, and the gas gets pulled out of the air instead of sitting on your greens.

Getting it in the drawer

1. One per crisper drawer. Gas builds in both the humid drawer and the dry one, so both get one.
2. Stick it to the side wall, not the floor. Up off the floor it stays dry, stays put, and nothing gets stacked on top of it.
3. Swap it monthly. The absorber fills up. On a subscription a fresh pair arrives each month, so you never have to remember.

What benefits most

The produce that reacts hardest to ethylene is also the produce households throw out most: broccoli, romaine and other leafy greens, cucumbers, and soft stone fruit. Broccoli is the extreme case — at 50°F, exposure to 2 ppm of ethylene cuts its shelf life in half (UC Davis, broccoli). Romaine reacts to as little as one ppm (UC Davis, romaine). The strongest producers to keep separate are apples, pears and cantaloupe (UC Davis, Bartlett pear).

Buying it

A single box is $11.99. On the monthly subscription it is $8.99 a month, shipped free, and you can modify, pause, or cancel it any time through your account. New to it? Start with the subscription — the absorber is a consumable, and the whole point is not having to think about replacing it.
