Our Review
Express Water's heavy-metal system adds a dedicated KDF stage to the usual sediment-and-carbon stack, making it a smart pick if your water report flags iron, manganese, or lead rather than just chlorine.
We like the built-in pressure gauges — a simple feature that takes the guesswork out of when to swap cartridges. It's modular too, so you can expand the system as your needs grow.
Pros
- KDF stage targets heavy metals specifically
- Pressure gauges show when to change filters
- Modular — add stages as needed
Cons
- Yearly cartridge maintenance
- Flow can dip as cartridges load up
The HU Recommendation
Start with a lab test (our $99 kit) before buying. The KDF stage is worth paying for only if you actually have heavy metals — otherwise a standard carbon system is more cost-effective.
