## Questions & Answers

**Q: what is the recommended manufacture filter change. or the life span of the filter how many gallons?
Thanks**
A: We have a lot of sediment and silt in our well water.  I have been using these close to 10 years now, and I change them every 3 months.  If I go too long, the silt gets past the filter and into the washing machine (that's where I notice it first).

**Q: Will these filters fit the express water whole house filter hsg?they are also 4.5 x20 filters. Would like to use this gradiant sediment filter**
A: Yes, the sediment filter will fit the 20 inch canister. That is a std size. It should go into the first position in a 3 canister setup.

**Q: Can i replace a dgd-5005- 20 with this dgd-2501-20? what are the consequent's replace more often?**
A: The DGD-2501-20 is designed to remove smaller particulate and is constructed of denser filter media than th DGD-5005-20, thus it my need to be replaced more often if the feed water quality has a higher volume of larger sized particulate.

**Q: Where is this made?**
A: The DGD-5005-20 Pentek is made in China.
