What is ZeroWater?

ZeroWater is a popular water filtration brand known for its advanced 5-stage filtration technology that removes 99.6% of total dissolved solids (TDS) from tap water. Unlike basic filters that only remove chlorine or odor, ZeroWater offers a much higher level of purification, making it one of the top choices for health-conscious consumers.

At Cuoll, we offer a range of water purification products, including ZeroWater filter pitchers, replacement cartridges, and under-sink filters, making it easy for you to maintain your water quality.

How Does ZeroWater Filter Work?

The ZeroWater filter uses five stages of filtration, which include:

1. Coarse Filter Screen – Removes fine particles and sediments.
2. Foam Distributor – Distributes water evenly to optimize filtration.
3. Activated Carbon & Oxidation Reduction Alloy – Removes chlorine, heavy metals, and organic contaminants.
4. Ion Exchange Resin – Replaces bad ions (lead, nitrates) with clean ones.
5. Ultra-Fine Screen & Non-Woven Membrane Layers – Final polish to remove any remaining impurities.

This multi-stage process is what allows ZeroWater to achieve TDS readings close to zero, hence the name.

Why Replacing Your ZeroWater Filter Matters

If you’re wondering why you need to replace your ZeroWater filter, here are some crucial reasons:

• Filter saturation: Over time, the filter media becomes full and cannot absorb more contaminants.
• Taste and odor: Old filters can cause a metallic or fishy taste in the water.
• Bacterial growth: Used filters may become a breeding ground for bacteria.
• Reduced performance: Water may pass through too slowly or too quickly without being fully filtered.

Not replacing your filter can compromise your health and render the entire system ineffective.

How Often to Replace ZeroWater Filter

General Replacement Guidelines:

ZeroWater recommends replacing the filter when your TDS meter reads 006 or higher. However, here are average estimates based on water quality:

Signs It’s Time to Replace Your ZeroWater Filter

Here are common signs your ZeroWater filter needs replacing:

1. TDS Reading Above 006 – The clearest sign using the provided TDS meter.
2. Water Tastes Sour or Metallic – A common complaint with exhausted filters.
3. Cloudy or Discolored Water – Indicates filter inefficiency.
4. Unusual Odors – Such as fishy, musty, or metallic smells.
5. Slow Flow Rate – Water drips slowly through the filter.
6. Visible Particles in Filtered Water – Means the filter media has broken down.

Factors That Affect Filter Life

Not all ZeroWater filters last the same. Several factors can affect how often you’ll need a replacement:

• TDS Level in Your Tap Water – Higher TDS = faster filter exhaustion.
• Frequency of Use – The more you filter, the faster it wears out.
• Storage Conditions – Exposure to heat and direct sunlight can degrade filter quality.
• Water Type – Hard water or well water typically contains more contaminants.

How to Replace a ZeroWater Filter

Changing a ZeroWater filter is easy. Here’s how to do it:

Step-by-Step Guide:

1. Remove Lid and Reservoir from your ZeroWater pitcher or dispenser.
2. Unscrew the Used Filter from the bottom of the reservoir.
3. Clean the Reservoir with warm water (no soap) and rinse thoroughly.
4. Screw in the New Filter tightly to prevent leaks.
5. Reassemble the Pitcher and fill with tap water.
6. Test the Water with the TDS meter to ensure it reads 000.

Pro Tip: Do not pre-soak the filter, and make sure the washer is seated correctly.
