—— WHAT YOU’VE BEEN SOLD
Most water treatment systems solve one problem. And create three more.
Water softeners use salt. Lots of it. You've hauled the bags. You've felt the slippery floors. And your water still isn't truly clean.
Reverse osmosis wastes gallons for every gallon it produces — and strips out the natural minerals your body actually needs.
For decades, the industry has sold you three separate systems, at three separate prices. The Hanish WaterCrest was built to end all of that.
"The finished product is clean, clear, great-tasting water at every tap — with all the healthy minerals your body needs, left in for your benefit."
—— WHAT WE REMOVE
You shouldn't have to wonder what's in your water.
Hanish systems remove what municipal treatment leaves behind — at removal rates tested and verified to NSF/ANSI standards.

Also treats chlorine, chloramine, THMs, PCBs, PFOS, hardness, and particulates down to 0.1 micron and 0.01 NTU all at flow rates hundreds of times greater than existing virus rated ultra-porous filters — with no drain line, no electricity, and no wasted water.
Plus… unlike reverse osmosis (RO), it does not strip the minerals your body needs.
—— THE WATERCREST LINE
Every home is like a person; each has different needs.
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

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.
Top line:
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

Cartridge service life: up to 2 years
What this system does NOT require:
No electricity
No salt

Warranty:Lifetime warranty on the system housing (transferable). 1-year 100% performance guarantee. NSF/ANSI Standard 53 certified media.
Topline:
Hidden under counter
Easy installation
Best protection for drinking water
BioGuard technology
Details:
The Hanish Water Under Counter System (UCS) installs out of sight beneath the sink and connects directly to your cold water line. From that point on, every time you turn on the faucet you get filtered water — no switching, no diverting, no remembering.
It removes bacteria, viruses, chlorine, pharmaceuticals, cysts, and trace metals at the point of use, costs less than a penny per gallon to operate, and comes with a lifetime warranty on the housing. A plumber or DIY home-owner handles the installation, and after that, it simply runs.
The same whole-house BioGuard filtration technology is working every time someone fills a glass, fills a pot, or runs water for a recipe. No clutter. No extra steps. Just clean water, every time the faucet turns on.
Best for: Kitchens, bathrooms, condos, townhomes, vacation cabins, and mobile homes. Recommended for people with weakened immune systems, Lyme Disease, and anyone prioritizing health-protective water at the point of use.
What it treats:
Bacteria, viruses, Legionella, E. coli, Salmonella, Cryptosporidium, Giardia, Pseudomonas, Mycobacteria, Aspergillus — 99.9999% removal
Chlorine and chloramines
Trace pharmaceuticals, endotoxins, metals, and DNA
Cysts — 99.97% reduction (WQA tested)
Particulates to 0.1 micron / 0.01 NTU

Clean Drinking Water, On the Counter, On Your Terms.
The Hanish Counter Top System (CTS) is the no-commitment upgrade to your drinking water that requires nothing from your plumbing and no one to install it. It sits on the counter, connects to your existing faucet in minutes and filters everything from bacteria and viruses to chlorine taste, trace pharmaceuticals, and heavy metals — leaving only the healthy minerals behind. If you travel, it goes with you. If you move, it comes along.
For families with children, the CTS is particularly well-suited to households where drinking water safety is the primary concern — especially for pregnant or nursing mothers, young children, or anyone with a weakened immune system. It removes 99.9999% of bacteria, viruses, Legionella, E. coli, Cryptosporidium, and more from the water your family drinks every day, with zero electricity and no chemicals involved.
It's also a practical first step for renters who can't modify their plumbing, or families who want dedicated drinking water filtration at the kitchen sink before committing to a whole-house system.
Best for: Kitchens, bathrooms, condos, townhomes, vacation cabins, and mobile homes. Recommended for people with weakened immune systems, Lyme Disease, and anyone prioritizing health-protective water at the point of use.

The Hanish Water Replacement Cartridges are the longest lasting, most efficient high flow performance cartridges on the market today easily lasting twice as long — or more — than any competitive systems.
Expected Cartridge Life varies depending on raw water source.
Choose from the following cartridges for your Point of Use system (Counter Top or Under Counter):
AS — Arsenic Reduction Cartridge (AS) Designed for homes where arsenic levels in the water supply are a concern — this point-of-use cartridge targets arsenic removal at the tap, providing an additional layer of protection for drinking water in regions where naturally occurring or industrial arsenic contamination is present. Replace every 4500 gallons
Fluoride Reduction Cartridge (FL) For households that want to manage fluoride levels in their drinking water — this point-of-use cartridge reduces fluoride at the tap, and is available as an add-on to the UTC under-counter system or as a standalone POU filter for targeted treatment at the kitchen sink. Treats up to 6093 ppm.
Nitrate Reduction Cartridge (NO3) Addresses nitrate contamination in drinking water — a particular concern in agricultural areas where fertilizer runoff can affect well water and some municipal supplies — this point-of-use cartridge is available paired with the UTC under-counter system or as a standalone POU unit. Treats up to 2500 gpg (grains per gallon).
All systems include a Lifetime Warranty on registered units and a 365-Day Performance Guarantee.
