## Questions & Answers

**Q: What material are they made of? is this better than the cheap pp (polypropylene) filters?**
A: Has been effective for me in a difficult well water situation

**Q: After u install this would your pressure of water drop ??**
A: I have had no drop in water pressure with this whole house water filter.  I used to have the carbon whole house water filter and I did have a drop in water pressure.  I really like this whole house water filter, because it is white and it will show the contaminants in the water supply.

**Q: Does the filter come with the O-Ring or should I buy that separately?**
A: Buy one separately, I used the same one three filters in a row and the fourth time I couldn't make it fit. It stretched too much.

**Q: What is the GPM range for the filter?**
A: I don’t know the exact gallons a minute but I have a 4000 square-foot house for kids and the wife and I. We have had no problem running it in our household for 20 years
