Topline:
Addresses homes on municipal water
For larger homes (3+ baths) or higher-use households.
4-stage whole-house system with Pre-Filter, BioGuard, ScaleInhibitor, and Carbon.
18 gpm flow rate
Clean water at every sink, faucet, shower in the house
Details:
The WaterCrest 4-PF is the one decision that touches every room — every faucet, every shower, every appliance — without demanding anything from you in return. It filters bacteria, viruses, chlorine, lead, trace pharmaceuticals, heavy metals, and hard water scale at flow rates fast enough to run the dishwasher, washing machine, and multiple showers at the same time — without losing pressure.
It installs once, filters at up to 18 gallons per minute across every outlet in the house, and asks for a cartridge change every two-three years — far less upkeep than the monthly salt refills a water softener demands. And unlike a softener or reverse osmosis system, it keeps the calcium and magnesium your body actually needs right where they belong: in your water.
For families, your kids drink from every tap in the house — the bathroom sink, the kitchen faucet, the shower head. The WaterCrest 4-PF covers all of it in one installation.
What it treats:
Bacteria, viruses, Legionella, E. coli, Salmonella, Cryptosporidium, Giardia, Pseudomonas, Mycobacteria, Aspergillus
Chlorine and chloramines (no taste, no smell)
THMs, PCBs
Trace pharmaceuticals, endotoxins, and DNA
Hard water scale (without removing healthy minerals)
Particulates down to 0.1 micron / 0.01 NTU
System specs:
Dimensions: 26"H × 42"W × 9"D
Vessel configuration: 4 vessels, each 5×20"
Flow rate: up to 18 gallons per minute — enough for the whole house simultaneously
Connections: 1" in/out
Operating pressure: 10–100 psi
Dry weight: 71 lbs.
Cartridge service life: up to 6 years
What this system does NOT require:
No electricity
No salt
No chemicals
No drain line
No water wasted
Maintenance: Cartridge replacement every 2-3 years — significantly less demanding than water softeners, which require heavy salt bags to be refilled every month.
Warranty:Lifetime warranty on all parts, (transferable). 1-year 100% performance guarantee. NSF/ANSI Standard 53 certified media.
