“Water developed an undesirable taste after 2.5-3 months. Changed filters with same brand of filter and taste went away. Came back again 2.5-3 months.”
Hi dear customer,
Thanks for your review.
Regarding filter lifetime
a. Our filter lifetime depends on 2 aspects: the elapsed time and the amount of water consumption.
If one of the two limits has been reached, the corresponding filter will need to be replaced.
Since the different areas will have different water conditions, the actual lifetime of the filters may vary and the actual situation shall prevail.
How our filter indicator works
---Please note that it is designed based on average water conditions; it cannot adjust itself to meet your local water quality.
In other words, it's perfectly normal that a filter needs replacement when the indicator gives no alert yet.
---Please note that you need to reset the corresponding filter lifetime indicator MANUALLY after each replacement since it's not designed to detect a new filter automatically.
If you have encountered any difficulty during the indicator reset process, please note that it does NOT indicate a faulty filter.
If you have any other questions, please feel free to contact us.
Enjoy the rest of your day!
Kind Regards
