What is Ethylene Gas?
Ethylene gas is the ripening agent which occurs naturally in nature. It causes fruits to ripen & decay, vegetables & floral to wilt. Controlling ethylene gas after picking will extend the life cycle of your commodity-allowing them to be held for a much a longer period of time at peak freshness. While refrigeration & humidity slow decay, they don’t halt the production of harmful ethylene gas and excess moisture produced from produce in refrigerated coolers.

The Effects of Ethylene Gas
You’ve seen the effects of ethylene gas damage many times: decaying fresh produce and flower bulbs with Lettuce russet spotting  and also on eggplants The yellowing of cucumbers, broccoli and brussel sprouts. The excessive odor on garlic and onions. The wilting of vegetables and cut flowers. On Apples the scald and loss of crunch,  and the rind breakdown on Lemons, Limes Oranges and Grapefruit.

If one can control ethylene gas levels, then you preserve freshness. This is a scientific fact and there are many way to solve this problem. Our amazing super filters will capture (absorb) Ethylene Gas, Moisture and Odors to keep your produce fresher lasting longer while reducing energy costs and your carbon footprint. These Super green filters are a simple solution for an age old problem.
