Questions & Answers

Have a Question?

Ask a Question
  • Can I fill the bottle directly from our lake and drink it

    Yes, you can as it does filter out bacteria and viruses.

  • Can you get a one like this... SEYCHELLE 28OZ EXTREME/RAD/ADVANCED FLIP TOP WATER FILTER That is stainless steel? Can you use a filter from SEYCHELLE 28OZ EXTREME/RAD/ADVANCED FLIP TOP WATER FILTER in a stainless steel one?

    No,  with the Extreme filter it would be too hard to get the water through the filter as you have to squeeze and suck the water through the filter. No, they will not fit.

  • Why doesn't this one "say" it filters out viruses and bacteria
