Imagine drinking water from your ZeroWater Filter and suddenly notice something is different in its taste than what you expect. Don’t worry too much as the problem is most likely time to change your ZeroWater filter and clean your device. When ZeroWater’s filters get dirty after rounds of purifying filtration, you may notice a difference in taste. Tap water contains various types of metals, and minerals. These substances can change the taste of your water and sometimes cause it to be acidic, fishy, or have a lemon-like taste. If after you filter water through your ZeroWater filter, it is likely a sign that your water filter is reaching the end of its lifespan. 

How to Care for Your ZeroWater Device

ZeroWater’s filters take your tap water through a 5-stage filtration process compared to our competitor’s 2-stage processes. This technology allows our filters to prevent bacteria growth within the filter and removes chemicals and contaminants that are listed under the EPA’s drinking water regulations. 

Most of our filters provide you with up to 40 gallons of usage (depending on your tap water’s TDS meter reading). These filters can remove substances such as Chlorine, Cyanide, Asbestos, Lead, Zinc, Iron, Chromium 6, PFOA/PFOS amongst others. Only by keeping your ZeroWater filter clean can it continue to remove these harmful substances from your water

Before you take apart your ZeroWater dispenser or pitcher, gather your materials for cleaning. You will need your free TDS meter (total dissolved solids measures water by parts per million, ppm) that came with your product, mild soap in a bowl of warm water, paper towels, and a cleaning sponge.

Now that you are ready to clean your Zerowater device, here are the steps: 


  1. Pour out the existing water in your device.

  2. Remove the lid and water reservoir from the top of the pitcher or dispenser.

  3. Untwist the filter from the bottom of the reservoir. Discard the filter via your local municipality recycling program or through ZeroWater's recycling program.

  4. Clean device with a mild soap.

  5. Rinse your device for at least 30 seconds or until the soap no longer appears.

  6. Once you are done rinsing, completely dry your device with a paper towel before reattaching.

  7. After drying, attach a new filter back onto the reservoir by twisting it onto the bottom of the reservoir.

  8. Fill the dispenser or pitcher up with cold water from your tap.

  9. When all of the water has emptied into the container, pour it into a cup or glass and use your TDS meter to test levels.

  10. If you receive a good reading which is 000ppm, you are done! If the number is higher than 006ppm, then you may not have a complete seal with the reservoir. Try tightening your filter or look for cross-threading with your filter.

When to Clean vs When to Replace

The lifespan of your water filter depends on how much water your household consumes and your water’s TDS meter reading. Our filters are meant to leave you with ZeroWater which is a 000ppm TDS meter reading. Regular testing of your water will help determine how often you should clean or replace your filters. If your water is between 051-200ppm, you’ll get 40 gallons out of your ZeroWater filter. 

Just like air filters in your home need replacing after dirt and dead skin particles clog it, water filters need replacing too. By taking a couple of minutes to clean your ZeroWater device and replace the filter when it has expired, you will be able to enjoy the benefits of clean, fresh, and great tasting water. If it is time to restock on filters, shop our replacement water filter packs that fit your home!
