It is crucial to drink clean water to keep the body safe from hazardous diseases. It is also important to note that filtered water from all sources might not be clean water.

In this article, we will discuss in brief Zero Water filters and when to change Zero Water filters. Let us look into how to change Zero Water filters, when to change Zero Water filters, and why it is important to change the water filter immediately.

What is the Zero Water filter? Are they really worth it?

The kitchen water filters that we find in most kitchens come with activated carbon that will absorb the inorganic and organic contaminants. Zero Water filters on the other hand are built with a 5 stage water filtration system that makes use of ion exchange technology. The advanced ion exchange technology has been found to be highly effective when it comes to getting the best-purified water.

In this filtration system, the water containing contaminants is run through ion exchange resins. These ion beads are filled with mineral ions (sodium ion beads). As ion exchange takes place, the beads will absorb the contaminant ions while the purified water will pass through.

Although the ion exchange technology sounds a little complex, the broken-down process is easy to comprehend.

First Stage

The first filter in a Zero Water dispenser is a coarse filter screen. This will effortlessly trap larger sediments and particles from the drinking water. Dust, rust, grit, etc., can be removed from water in this stage.

Second Stage

In the next stage, there is a foam distributor installed to ensure the water is dispersed evenly across the filter for effective filtering.

Second Stage

Third Stage

For the next step in filtration, the filter uses a multilayer technology with activated carbon and oxidation reduction alloy. This layer is specially designed to trap all organic contaminants to prevent bacterial growth.

Third Stage

Fourth Stage

The next stage handles the removal of inorganic compounds such as metals, nonmetals, and radium with the help of the ion exchange resin.

Fourth Stage

Fifth Stage

The last stage contains non-woven membrane layers. This ultra-fine screen is in place to remove any fine particles that have escaped the previous stages of filtration.

Fifth Stage

A Zero Water Filter is definitely worth the investment, owing to its excellent recycling program. The Zero Water filters come with a recycling program offered for the old filter after use. You can send the old filter back to the manufacturer for it to be recycled by which you can also procure a 50% discount on the new filter. This is an environmentally friendly and economically beneficial feature added to purchasing a Zero Water filter dispenser.

Frequently Asked Questions:

1. What does ZeroWater filters remove?

Zero Water filters are highly recommended to remove organic and inorganic pollutants from drinking water. Zero Water filters can effectively remove lime, lead, chlorine, glyphosate, PFAS, and microplastics. Its specialized 5-stage water filtration also prevents bacterial growth.

2. What Is a TDS Meter?

A TDS meter is a handle-held device that is used to measure the Total Dissolved Solids in a solution. A TDS meter is usually used to measure the total dissolved solids in water. It is a good method to estimate the water quality of filtered water or even tap water quality.

3. How do you take the filter out of a ZeroWater pitcher?

Removing the filter from a Zero Water filter can be done by taking out the lid and water reservoir with the protective blue cap.

4. Zero vs Brita. Which is better?

Both the Zero water filters and Brita filters come with their own set of advantages and disadvantages. A recent study revealed that Brita water filters were able to remove 40% of TDS or total dissolved solids. Although this is an impressive figure, Zero Water Filters perform significantly better.
