C7500 Premium Countertop Water Filter System with Intelligent Monitor, 1,000 Gal.
WaterChef® C7500 Countertop Water Filter System
YOUR INTELLIGENT COUNTERTOP FILTRATION SOLUTION
Combining the power of solid carbon block filtration with a unique, proprietary blend of additional filter media, WaterChef’s innovative Big Block™ filtration technology maximizes contaminant reduction while delivering up to 1,000 GALLONS (3,785 L) or one year of freshly filtered water from a single cartridge!
Certified reduction includes 78 common tap water contaminants, including:
- Lead & Mercury
- PFAS "Forever Chemicals" (PFOA/PFOS)
- Microplastics
- Cysts (Giardia, Cryptosporidium)
- Chlorine
- Chloramine
- Chlorine By-Products (includes Trihalomethanes)
- Synthetic Contaminants (includes Pesticides and Herbicides)
- Industrial Contaminants (includes Volatile Organic Compounds (VOCs))
- Emerging Contaminants (NSF/ANSI 401) (includes Pharmaceuticals and Detergents)
- Petroleum Contaminants (includes Benzene and MTBE)
Additionally, this advanced formulation retains beneficial essential minerals (like calcium, magnesium, and potassium). The result is great-tasting water that's clean, crisp, AND naturally balanced (without the "flat" taste associated with reverse osmosis or distillation).
(See the WaterChef C7500 Performance Data Sheet for a complete list of certified reductions.)
Tired of replacing small, under-performing cartridges every few months? The C7500’s high-capacity CR75 cartridge requires just one replacement per year for most households, delivering a much lower cost per gallon than pitcher, faucet, and other countertop filters.
One cartridge replaces over 7,500 single-use plastic water bottles, reducing waste while saving you money. Unlike low-capacity filters that remove fewer contaminants and may require up to 25 replacements per year, the C7500 offers dependable, long-lasting filtration you can count on.

Intelligent Monitoring takes the guesswork out of your cartridge replacements. Unlike countertop filters with simple timer-based monitors, WaterChef’s Intelligent Monitor tracks your actual usage. You'll never discard a filter cartridge too early or continue using one past its certified capacity.
Crafted from stainless steel and high-impact ABS, the C7500 combines durability with a sleek, space-saving design that complements modern kitchens. Installation takes minutes and requires no tools, making it ideal for homes, apartments, offices, RVs, dorm rooms, and rentals.
(Available in white/stainless or black/stainless.)
NOTE: The C7500 is not recommended for pull-out or spray-style style faucets. For those setups, we recommend the WaterChef® U9000 Under-Sink System.

BEST BUY OF 2022
I'm obsessed! My hair was getting so dry, frizzy and damaged no matter how much money I spent on expensive hair products. I bought this water filter and it's softer than ever...
WONDERFUL SHOWER
Replace whatever you have with this! Wonderful shower head, great pressure, with good water flow settings. Blows the competition out of the water!
WHAT A DIFFERENCE!
Oh my god! What a difference in my water! I am so glad I found this! I will buy this product a millions times over again! If you are looking for a water filtration system for you home, WaterChef is the product you want. Great tasting water at its best!
GREAT UPGRADE
Replaced my Culligan 2 cartridge under counter filter with this. It’s going to be so much easier to replace the filter cartridge. Water flows out probably 30% faster and tastes great. Install was simple.
REAL WATER!
I knew I had made the right decision to buy this product when I first took a drink of the filtered water. It didn't have a funny taste to it which was a problem with my previous system. I also loved the slim design of the casing. Thanks a heap!
WHY DID WE WAIT SO LONG?
We are very happy with our new filter. Not sure why we waited this long to get one, installed very easy and the water is clean and smooth! Thank you.
GET ONE TODAY!
Words can not describe how much I love my shower wand with filter! Best showers I’ve ever had, no kidding!
VERY HAPPY!
I am very happy with my water filter. I have great tasting water now. Three people in my apartment complex each bought the system and are extremely happy with it.
FIVE STARS.
I give this product and the company FIVE STARS. I wish every organization did business with was as helpful and friendly to deal with.
