Why does my water filter taste like lemon?

The taste of your water is commonly affected by the time which it takes for a filter to expire. Filters typically last about six months and some may even go up to three years before they must be replaced.

The most common cause of your ZeroWater filter giving your water a somewhat acidic lemon taste is a buildup of TDS. Any observable change in taste or odor is a frequent indicator that your ZeroWater filter needs to be replaced.

This is due to the fact that ZeroWater filters decrease 99.6 percent of TDS, including lead and other heavy metals! When a filter reaches the end of its useful life, it may emit a lemon flavor or odor.

Water with a pH of three or below tastes pleasantly sour or acidic, especially when blended with sugar, according to researchers. That is why sodas and fruit drinks taste so delicious.

If your water filter is past its expiry date, then that’s the reason why it tastes like lemon. If you use filtered water past its expiration date and don’t change out the filters as needed, they’ll become acidic and may taste bad.

The water filter has a shelf life, meaning it can become acidic over time. Filters are designed to stop the passage of particles through their pores that could cause damage or alter the taste of your tap water. However, if your filters have been exposed to air for too long they may start tasting like lemon when you pour them into a glass.

The explanation is likely to be a result of all the metal and other contaminants that are stuck in it. These metals get into your drinking water through various sources such as construction sites, farm fields, power plants, etc.

If you’re using a filter on an ongoing basis or if there’s not enough time for all these metals to settle out then they might end up getting filtered into your water supply.

If and when your Zero water filter begins to taste like lemon, you have many options.

  • Rinse the filter thoroughly.
  • Check that the pitcher and other filter components are in good working order.
  • Replace the filter
  • Check the TDS levels in the filtered water with your TDS meter.
  • Ascertain that you are filtering cold water rather than warm or hot water.

Does zero Water Filter Expire?

Yes, if you use your zero water filter after its expiry date, which is 20 gallons for pitchers and 400 gallons for faucet mount filters, it may have expired.

The taste of your water is largely dependent on the effectiveness of your filter. The amount of impurities in the water indicates that the filter has lost its ability to purify it effectively.

Zero Water filters are designed to be used for long periods of time, but they do expire. If you want your filter to last longer than the three-year warranty period, it’s best not to use tap water in the filtration process and instead only use filtered or bottled water.

Zero water filters are replaceable but they last long enough to be replaced when they start tasting bad. The filter will get gross after time, so it’s best to just replace them with a fresh one every few months.

How to replace a Zero Water Filter

To replace your zero water filter, disassemble the filtration system, remove the old filter by turning it anticlockwise from its base, remove the package and blue cap from the new filter, and install by rotating it clockwise from its base until there is a full seal.

When the lid is removed, it’s easy to access the filter and replace it. To remove the reservoir, press on one of its sides with your thumb. The Zero Water Filter can be replaced by pressing down on the bottom of the water tank until two tabs are released.

The new filter should be securely placed in place without any gaps between it and the lid or reservoir before replacing both pieces back onto their respective holders.

If you find that your water taste like lemon after installing a new filter, it has probably been left in the lid.


If you’re noticing a strange taste in your water, it may be due to the filter. The Zero Water filters are designed with an air-tight seal that prevents leaks from getting into the reservoir and contaminating your drinking water.

However, there is a way around this problem: if you notice any leakage or if something has been placed inside of the housing during installation then just replace your old filter with a new one. You should also disconnect power before attempting to remove or install anything on top of your system.
