Best for homes on well water
Ideal for 1–3 bathroom homes.
3-stage whole-house system on the Big Blue platform. Same NASA-derived BioGuard technology.
18 gpm flow rate.
Details:
The WaterCrest-3BB delivers the same core whole-house filtration technology as the WaterCrest 4-PF in a slightly more compact footprint — the right fit for homes with moderate water demand or where installation space is a consideration. Same no-salt, no-electricity, no-chemical approach. Same 2-3 year cartridge life. Better than water softener quality without the monthly maintenance.
The WaterCrest-3BB is a practical, no-compromise entry into whole-house filtration for homeowners who want comprehensive coverage without the full 4-PF configuration.
What it treats:
Bacteria, viruses, Legionella, E. coli, Salmonella, Cryptosporidium, Giardia, Pseudomonas, Mycobacteria, Aspergillus
Chlorine and chloramines
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 × 41"W × 9"D
Vessel configuration: 1 vessel (4.5×20") + 3 vessels (5×20")
Flow rate: up to 18 gallons per minute
Connections: 1" in/out
Operating pressure: 10–100 psi
Dry weight: 66 lbs.
Cartridge service life: up to 2 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 — far less demanding than the monthly salt refills that water softeners require.
Warranty:Lifetime warranty on the system housing (transferable). 1-year 100% performance guarantee. NSF/ANSI Standard 53 certified media.
