- What does the three-stage setup actually filter?
- The stages pair sediment filtration with carbon filtration. That targets sediment, rust, chlorine and the taste and odor chlorine leaves behind. It does not remove dissolved minerals or TDS.
- Does it soften hard water?
- No. It is a filter, not a water softener, so it will not remove calcium and magnesium or stop scale. Homes with hard water need a separate softener.
- How often do the cartridges need changing?
- Cartridge life depends on water quality and how much water the household uses. Sediment cartridges usually load up faster than carbon, and heavy sediment shortens the interval. Check them on a schedule and replace when flow drops or taste returns.
- Can I install it myself?
- It goes on the main water line, so it needs basic plumbing work: cutting into the line and making leak-free connections. If you are not comfortable with that, hire a plumber.
- Will it reduce water pressure?
- Any whole-house filter adds some restriction, and a loaded sediment cartridge adds more. Expect little change when cartridges are fresh and a drop as they clog.
- Does it need power or a drain?
- No. It is a passive inline filter, so it needs no electricity and no drain line, unlike reverse osmosis.
