ZeroWater 5-stage water filter replacement - 2 pack

I screw the filter in and fill up the reservoir directly from the tap. It takes a few fills and waiting between. this works for the 1st %26 2nd time. I always check after filling to see if it is still working. For refills after 2, I have to put reservoir sideways or the water doesn't drain well. I drink almost the whole container each day. I love it

Although these filters clean the water well, they do not last long. The filter only lasts about a month with only myself using the Zero water pitcher. After about a month, the water started tasting citrusy. That meant that the filter was done. It cost $30 for two new filters. That is $15 per filter. I watched a review online, and found out that this filter is the most expensive of the pitcher filters. I just had a kitchen water filter installed under the sink that is supposed to last 12 months for almost the same cost as the one that only lasts me one month. If the filters lasted at least three months, I would recommend this product. If you don't mind spending $15 per month on water, then this product is fine.
