“Thanks for the introduction to these filters. We have had them in service for three months now and we can tell a tremendous difference in moisture removal and food odor removal. The staff in our operation were asked to monitor the condition of the freezers and coolers before and after the installation. They said they could tell a real difference. I would recommend you try the Captain Cool Air filters and you to will tell the difference."

What Clients Say About Captain Cool Air

"The filters have worked great! I have noticed the food lasting much longer; at least two times longer. This has allowed us to order our produce in cases instead of individual packages. The produce is much cheaper by the case. Set at the same temperature the cooler feels much colder with the filters installed. There is very low maintenance and they don't wear out. I would highly recommend Captain Cool Air Filters for any refrigeration systems."

"The food definitely lasts longer. The walk in stays cold even when the door is cracked. The Coolers also get to temperature a lot faster. It also feels colder and doesn’t feel as humid."

Zeolite is also being used in the medical field in various ways. In some cases, is liquefied and ingested to clear the body of impurities. Zeolite-based oxygen concentrator systems are also widely used to produce medical-grade oxygen. Specifically, the zeolite is used as a molecular sieve to create purified oxygen from the air using its ability to trap impurities.
