## Questions & Answers

**Q: Is there a trick to getting clean water through this thing? Even Hulk Hogan couldn't squeeze hard enough as it is.**
A: The filter should be able to process a gallon of water in less than 10 minutes. Two fixes ... 1. There could be an air bubble trapped in the filter or tube, to remove it, unscrew the end cap that is attached to the tube and filter (make sure you do not get water on the drinking water outlet), then screw the cap tight again and test the flow.  2. Use the included backwashing syringe to clear the filter, there might be much debris from turbid water slowing your flow.

**Q: Why does the initial filter last for 500 gallons but the replacement filter only lasts for 25 gallons? that seems like a ridiculous difference.**
A: There are two replacements for this product. The main membrane would still last for 500 gallons of water and then the carbon capsule is 25. These are two separate filters.

**Q: Where is this product made?**
A: Our products are made designed in Switzerland and made in South Korea.

**Q: Will this work for well water?**
A: It should work for any water source. Just know, the dirtier the water, the more often it needs to be replaced. Also, it is not made to filter large amounts if water, and it's very slow.
