Water not tasting right

Ratings looked good,  but noticed after a few days, water tasted like plastic, To be fair, maybe I just got a bad one.  ordered a different brand...now water tastes perfect.  Stuck with them, can't return.

Well i bought these filters and installed them. They initally left a slightly black sediment at the bottom of the filtered water side containment. I flushed that down the drain as well as the 2nd round of the initial use. After that the water tasted great and I was very excited to not need to purchase any bottled water. However just a few days later my wife mentioned a metallic taste to the water. I initially thought it was the storage container we are using but it was coming directly out of the filters. Going to see if they can be refunded or replaced with a new set and hope that i have better luck. I have no idea why the taste has changed.

I have not complaints about the pitcher but the filtration is somewhat disappointing. The chemical taste of the tap water is still very apparent. I guess I'll try a ZeroWater next time.

The water taste funny after a few weeks. You need to replace the EXPENSIVE filters VERY frequently. Not worth the money. Buy a BRITA. You will be very happy with a BRITA.

I have been using ZeroWater ZD-018 for a little over a month.  The water taste great.  The water quality went from 000 to 003 in about 4 or 5 weeks.  Instructions say to change filter when meter reads 006.  Worried that this will happen in another month.  Filters are not cheap.

The white lid on top does not sit properly.  Keeps sliding off the unit.  Not happy with this

It does not filter water adequately! Water tasted like tap water!!

I don't know why but the water tastes horrible after I installed the filter.  I ran the water for a while like it said to do and have tried using for a couple weeks but I just can't stand the taste.  It apparently doesn't work.

Update: It seems to taste fine in the morning and afternoon but horrible in the evenings.  Not sure why that is.

Water tastes a bit different than using the factory brand filters.

I had an 8 gallon tank and decided to get a more traditional shaped ten.  I never had trouble with the 8 and I have only had trouble with the ten.  I can only think it must be the filter at this point.  I've done regular water changes, siphoning, appropriate food, appropriate fish, and my water looks terrible.  My beta looks sick, and now my snails are having issues, and two fish died.
Water tests are normal, but it looks awful. I replaced the cartridge a few times in the last couple months to no avail.  I tried a little algae fix in case it was that ( it wasn't).
Now I have to go buy a different filter and hope the fish live.

There is some leak in the filter, causing the beads to come out. Only happening in one of the filters, the rest don't know yet since still packaged. As a result I'm not sure water is being filtered properly also I can see the black beads when I pour myself a glass :(

After reading the reviews here, I bought this product from a local store.  I was happy with the product for about two weeks then the water changed to the "fishy" taste some reviewers mentioned.  It was bad. Really bad.  It does taste as if someone dipped fully scaled fish in the pitcher.  From what I see from other reviews the original cylindrical filter was fine but quality control issues started with the newer bullet shaped filter.  Luckily, the store was good about taking the product back and I got more filters for my Brita system.  I would be a good product if they can resolve their quality control issues.

I am not impressed with the taste of water that this water filter provides.  My sweetheart got this for my birthday and I won't hurt her by complaining more than usual as we did the red dye test and it passed.  I would not purchase this myself.

Everything works great, however the water has a plastic taste. Not sure if it is the unit or the water. I believe it is the machine.

Initially there was an immediate difference in the taste of my water after installing this new filter. Now however, after only a couple of months, that old bitter, not so clean taste of the water is starting to return. At the price for this filter vs the price for purified water from the store, it's almost not worth it.

I'll be the first to admit, the water produced by the ZeroWater filtration system is some of the best tasting water I've ever had.  I really liked the pitcher and was so excited for the first two weeks of use.  After approximately two weeks of daily use, the water begins to taste "lemony" and is undrinkable.  The unfiltered water rating in my area is 700+ ppm so I expected the filters not to last as long they might in areas with softer water; however, two weeks per filter is unacceptable given the price of the filters.

I'm disappointed in the short life of the filtration system and have ultimately stopped using mine.

I just started to use this filter and it makes the water taste terrible. It tastes like some kind of chemical. Nothing like the Britta filters I've been using. This filter doesn't filter out the chlorine The water out of the tap tastes much better.

These filters were not satisfactory to me.  The water had a different taste than other filters I have purchased.  Will not purchase again.
