when to change zero water filter

No matter what brand and model we choose, water filters would eventually need replacement. Hence, it is important to know the lifespan of your water filter and when its quality declines.

ZeroWater is one of the most prominent high-quality water filter brands that many homeowners use. To get the best out of its portable design and excellent filtration capabilities, knowing when to change Zero water filter is necessary.

Generally, Zero water filters need replacement after approximately 2-4 months of usage. In this article, I will discuss their average lifespan and replacement procedures. Let’s begin!

What Makes ZeroWater Filter Stand Out?

Why do many people switch to ZeroWater filters? Zerowater offers a water filter pitcher and dispenser with a quick-fill, ready-pour, and drip-free technology.

But the unique selling point of these products is that they have incorporated a high-performing 5-stage filtration system with a highly adaptable ion-exchange technology.

This system works in the following sequence: The first filter is the coarse filter; it sifts out fine particles and sediments like dust, grit, and rust from your drinking water.

The second stage is the foam distributor, which disperses water evenly across the width of the filter to ensure that most of the particles in the water are caught.

The third stage uses multi-layer technology: activated carbon and oxidation reduction alloy filtration. This filter removes organic contaminants (chlorine, chloramine, mercury, herbicides, and pesticides) and hinders bacterial growth.

The fourth stage is the comprehensive exchange of ion arrays. The ion exchange resin strips off inorganic compounds such as metals (lead, aluminum, zinc, asbestos), nonmetals (nitrate and fluoride), and radium.

Lastly, the fifth stage utilizes non-woven membrane layers to discard the remaining ultra-fine particles.

Furthermore, ZeroWater filters have received an NSF endorsement for their excellent absorption of chromium-3, chromium-6, and lead.

ZeroWater filters will help you remove 99.6 % of total dissolved solids in your water efficiently. You will also get a free TDS meter for every purchase of a 5-stage ZeroWater pitcher or dispenser.

How Much Water Can I Filter With ZeroWater Filters?

TDS or total dissolved solids are the main culprit for water turbidity. The amount of TDS present in your water predominantly determines the volume of water you can filter, and it usually varies depending on the place of your residence.

According to the EPA (Environmental Protection Agency), the maximum permissible TDS level in drinking water is 500 ppm. But the safe levels range between 300-500 ppm.

Sources of total dissolved solids include soil erosion, sewage, fertilizers, road runoff, and industrial discharges. Generally, ZeroWater filters can treat 95 to 200 liters (approximately 25-52 gallons) of water with 50-200 TDS levels.

Let’s say you have tested your home water, and you get an exceptionally high TDS level (assuming it is more than 500 ppm). In such a case, your filter could only purify no more than 8 gallons of water.

To clear up some complaints online claiming that Zero water filter only lasts 2 weeks, yes it could happen, but the problem is not always about the filter quality but your overall water quality.

On the flip side, if your TDS level is at the low end, you should get 40 gallons of filtered water.

What Is the Estimated Lifespan of ZeroWater Filters?

ZeroWater filters undoubtedly outperform competing filters with their notable and excellent features. But how long should we wait to replace Zero water filter?

It is crucial to determine a Zero water filter lifespan because it varies depending on the model capacity and how often it is used, in addition to the TDS level mentioned above.

A 5-stage water pitcher model has a service life of 20 gallons, which roughly translates to 1 to 2 months. On the other hand, a 5-stage water dispenser can dispense about 25-40 gallons of water or a maximum of 2-4 months.

Suppose you have private well water. Groundwater does not receive the same services as municipal water, so chances are it could contain higher TDS concentration. Thus, your filter will require replacement more often.

The higher the TDS content, the harder the filter is working. You may not always get the advertised Zero water filter life expectancy. Hence, you must consider replacing the filter when the water quality tester reads “006” or more.

How Do I Know When to Replace My ZeroWater Filter?

There are four ways to tell if your ZeroWater filter has run its course :

  • A dramatic change in taste, color, and odor. You can always detect issues in your water quality through your senses. If your previously crisp water turns cloudy and smells/tastes funny, it’s a warning sign that your filter needs replacement.
  • Sedimentation and Contamination. If you see chalky white stains on your drinking glass and various contaminants floating in your water, change the filter.
  • Consult the user’s manual. Your water filter package always comes with a set of instructions. Replacement time can vary between 2-6 months depending on the model you bought.
  • A slow trickle of dispensed water. A slow dispensing process means that your water filter might be clogged because of the accumulation of contaminants over time.

Zero Water Filter Replacement Instructions

Replacing Zero water filter is relatively easy and quick to get done! Follow these steps to install your newly-purchased ZeroWater replacement filter :

  • Ensure that the O-ring is properly aligned to the head/cap of the new water filter to have a proper seal.
  • Unscrew the old filter by twisting it counterclockwise until it’s free.
  • Mount the new filter by turning it clockwise until the seal is tight.
  • Get rid of the old filter. Wrap it in a recyclable bag before throwing it away.
