Out here in Texas especially since I'm close to the Gulf of Mexico you never know what you might find in your water. Several months ago I had bought the Camco RV Water Filter Kit and it seemed to make a difference in the quality of water coming through our home. I realized that we needed to replace the filter so I went ahead and bought a 2 pack off of Amazon for $20.76! You can find the item under this title, "Camco 40045 TastePURE KDF Water Filter - 2 pack". If you are wondering, this item was also on a super sale! I normally change mine out every 2-3 months so overall in my opinion I think it's a worthy investment.
