The older your filter is, the more contaminants it holds. “Unloading” is a process that eventually occurs in every filter over time. Once saturated, the filter will allow small amounts of contaminants back into your cooler.
We encourage you to enroll in our Auto-Ship program. As part of this plan, not only will you receive FREE SHIPPING on your replacement filters, your orders will also be processed automatically when filters are due for replacement. Contact us for details.
