The WHP1 is the cheapest genuinely useful thing Express Water sells, because it is the one product in the catalogue with no consumable attached to it - the 50 micron screen is flushed rather than replaced, so the $61 is the entire lifetime cost. Its job is to catch the coarse material that would otherwise blind off a $200 cartridge set, which makes it the correct first purchase for anyone on a well or an old municipal main, ahead of any of the systems above. Fifty microns is deliberately coarse and it will pass silt, so it complements rather than replaces a pleated sediment cartridge. The clear housing means the flush interval is obvious by eye instead of by guesswork. There is no certification and the one-year warranty applies, but on a $61 mechanical part with no electronics that matters less than it does elsewhere in the range.
- Reusable screen - flushed rather than replaced, so there is no ongoing filter cost
- 1 in and 3/4 in adapters supplied, fits most mains
- Clear housing shows loading without dismantling anything
- Correct protection ahead of any cartridge system, softener or water heater
- Wide 15 to 115 PSI operating range
- Cheapest product in the range at $61
- 50 micron is coarse - it passes silt and does not replace a pleated sediment cartridge
- Requires a bucket or drain position under the flush valve
- No NSF certification
- One-year warranty
- Express Water files it under accessories, so it is easy to miss when buying a system
- Clear housing must be kept out of direct sunlight
The WHP1 is a spin-down sediment pre-filter with a 50 micron reusable mesh cartridge in a clear housing, fitted to a stainless steel mount with 1 in and 3/4 in adapters supplied. Rather than being replaced, the screen is flushed through a valve at the base. It operates between 15 and 115 PSI at 0.25 gallons per second and includes a pressure gauge and release button.
