ADVANCED Replacement Filter for the 28oz Travel Safe Bottle

Q: What bottle does this filter fit?

A: This filter fits the 800ml Travel Safe bottle, the Military Canteen and the Water Pump. The Advanced Filter can also be used with the Stainless Steel Filter Bottle, however, because it has a 20% reduction in flow rate compared to the Fast-flow Filter, it is deisgned to work best with a bottle that can also be squeezed while drinking. Some customers don't notice a difference using the Advacned Filter with the Stainless Steel Bottles, while others find it noticeably different.

Q: What does BPA-free mean?

A: A BPA-free product is one which does not contain the compound BPA or Bisphenol A. BPA is a compound used to make polycarbonate plastics (clear, shatter proof plastics) and epoxy resins (glues and coatings). This compound has the same properties and mimics the effects of the female hormone estrogen. Research has shown that BPA has a negative effect on fetal and infant brain development and behavior. Links have also been made between BPA consumption and obesity. A study by the Yale School of Medicine in 2008 found a connection between BPA and the interference with the brains cells related to memory, mood and learning. Many other studies have been undertaken and have shown links between BPA and cancer, thyroid dysfunction, reproductive issues and attention deficits. All of our products are BPA-free.
