Product overviewManufacturer material
You like your water with more alkalinity, and you want it from the pitcher already in your fridge, not from a case of bottles.
The Alkalizing Water Pitcher Cartridge is the alkaline pitcher replacement filter for the Crystal Quest Water Pitcher Filter System. It is a specialty cartridge with one published purpose: to enhance the alkalinity of the water you pour. Drop it into the same pitcher you use with our other cartridges and every refill comes out with added alkalinity.
At a glance
- One clear job: enhances the alkalinity of your pitcher water
- Fits the Crystal Quest pitcher you already own, in any color
- Swap freely between alkalizing, standard and specialty cartridges as your needs change
- Simple care: cold water only, replace when taste, odor or flow changes
- Packs of 2, 4 and 6 so the next cartridge is on hand
What you are looking at
A slim pitcher cartridge with mesh inlet screens on top, filled with media designed to enhance alkalinity. It presses into the bottom of the pitcher's reservoir and seals, so the water you pour into the top passes through the media before it reaches the pitcher below.
How an alkalizing pitcher cartridge works
Alkalinity, explained
Alkalinity is water's capacity to neutralize acid. In everyday water it comes mostly from dissolved carbonate and bicarbonate. Alkalinity and pH are related but not the same thing: pH is a snapshot of how acidic or basic water is right now, while alkalinity is the reserve that resists change. Water with more alkalinity holds its pH more steadily.
Why a pitcher suits it
A pitcher filters by gravity, so water moves through the cartridge slowly and spends time in contact with the media on every pass. That steady contact is how the cartridge adds alkalinity to each refill without pumps, power or plumbing.
What it reduces
Primary targets: none listed. This specialty cartridge is designed to enhance the alkalinity of filtered water, not to reduce contaminants.
Not designed to treat: chlorine, VOCs, THMs or heavy metals, and it is not for water that is microbiologically unsafe or of unknown quality. When you want the pitcher's chlorine, VOC, THM and heavy metal reduction, use the Standard/SMART Water Pitcher Cartridge.
Why Crystal Quest
- Straight claims. This cartridge's purpose is alkalinity, and that is all we claim for it. No miracle language, no borrowed test results.
- A whole family of cartridges for one pitcher. Standard/SMART, fluoride, arsenic, alkalizing and DI, so your pitcher can change jobs without being replaced.
- Made in the USA. Over 1,000,000 people served since 1994, under ISO 9001 quality management.
- Real help. Our water filtration team can help you decide between alkalizing, standard and a full drinking water system.
Where it fits
This cartridge, part number CQE-RC-04147, fits the Crystal Quest Water Pitcher Filter System in every pitcher color. The pitcher holds one cartridge at a time: choose this one for alkalinity, or the Standard/SMART cartridge for multi-contaminant filtration. Want both at once? Crystal Quest under-sink reverse osmosis systems can add an optional alkaline cartridge after full filtration. Single, Pack of 2, Pack of 4 and Pack of 6 all contain this same cartridge.
Common questions
What does the alkalizing cartridge do?
It is designed to enhance the alkalinity of water filtered through the Crystal Quest pitcher.
Does it reduce chlorine or other contaminants?
No contaminant reduction is listed for this cartridge. For chlorine, VOC, THM and heavy metal reduction, use the Standard/SMART pitcher cartridge.
How often should I replace it?
No fixed interval has been published for this cartridge. Replace it when taste, odor or flow changes. Actual life depends on feed water quality, system configuration and usage.
Which pitcher does it fit?
The Crystal Quest Water Pitcher Filter System, in any pitcher color. The pitcher manual calls for Crystal Quest approved cartridges only.
Is alkalinity the same as pH?
No. pH tells you how acidic or basic water is at the moment. Alkalinity is the water's reserve against acid, mostly from carbonate and bicarbonate. This cartridge's published purpose is to enhance alkalinity.
Can I get alkaline water and chlorine reduction together?
Not from one pitcher cartridge, because the pitcher holds one at a time. For both, a Crystal Quest under-sink reverse osmosis system with its optional alkaline cartridge filters first and then adds alkalinity.
