This is the second time I try this water dispenser, the first time inpurchase it from Costco, it worked fine for couple of months then the water start tasting awful. So I had to return it.
I thought of giving it a second try and to buy it from amazing this time, on the first use, the water tasted awful, it had a metallic taste. I tried following the instructions to sanitize it and remove metal deposits, it worked fine for couple of days then the water again start tasting bad!
I don't recommend this item to any one!
I will never buy it again!

Used the blue filters in the past and had great water and bought two of these and my water out of the refrigerator tastes like it's got a chemical taste.  I'm very disappointed in this two pack.  I noticed these filters are made overseas where there is no Quality Control. So if you like contaminated water that tastes of chemicals buy this filter.

The product is bad not the seller. The filter lasts very little time and it turns the water VERY ACID AND SOUR, it's disgusting when you put it in your mouth and leaves your mouth dry. When I put the meter in expecting it to be 0 for ZERO water it came up as 171 and I was super shocked, I tested it out on tap water and got 56. It's an absurd for the fabricators to have this type of manner with the buyer!

Water doesnt taste good coming through this filter. Air is shooting out of nozzle and water is leaking out of nozzle. Would never buy again!

I should have believed the reviews. The filter lasted a few weeks before it started to taste funny. After a month, it tastes and smells like you're drinking water out of a garden hose. Into the trash and back to the official filter.

Makes the water taste really bad! It's even worse if you spend a day at a hot place.

The filter left terrible tasting water. It had a "rubber" taste to it. My wife refuses to drink water or use ice from the refrigerator. I would return the filters if I knew who or where to send them

The water tasted awful. I have to throw them away and go to Home Depot to get a new one. Since the time to return had expired, I could no longer return them.

The water tastes terrible. I have never had a problem with our water tasting bad but something inside the tank is causing it to taste like chemicals. I have flushed it out completely at least a dozen times and it helps temporarily but the bad taste comes back after time, especially if the water has been sitting in the tank for a couple of days. I was hoping it would improve over time, especially since I had to pay a plumber to install it. Unfortunately, it has not gotten any better and the return cut off was 3 days ago. I am worried the water could be bad for my familys health.

This thing tastes like poo. It won't dissolve in hot water. Amazon must have sent old inventory. Anyone who buys will regret it. I going to return this. I will never order this again.

Terrible water. I tested with lab facilities in my lab and the fluoride, magnesium, and copper are way off.... For your own health, don't buy this water. Plus, it tastes really bad. if you google "Nestle water taste bad" there're thousands of people commenting on the issue as well. Well good luck, Nestle just make it like a lottery, either you're lucky and get some normal tasting water, either your water is gonna suffer from horrible tasting water.

Water tastes like metal. Unable to get refund or exchange. Stopped drinking water from it due to health concerns from taste

I would not buy this item unless you own the filter company. Our town has a new state of the art water filtration plant and the filters on this item do not last more than 40 cups of water. I have used 3 filters for less than 60 cups of water. The water has a lemon smell and taste to it after using it for 23 cups. NOT RECOMMENDED.

Major waste of money and a huge disappointment. Past return date or would send back for a refund. Just like so many other reviewers, my " filtered" water smells and tastes so bad it is unusable. Has an extremely strong chemical/plastic taste and odor that just has to be toxic to the consumer. New filters are $66 each, times three, so very nearly the same as buying a whole new unit. Katadyn customer service spoke as if they had never heard of this issue before, yet others have reported the same issue to them, as evidenced by their reviews here. They told me to clean the new filters! Two hundred thirty five dollars down the drain. Don't make the same mistake I did! Zero stars!!!

I filled this with fresh water and pulled some water from it an hour later and it has a TERRIBLE taste of plastic. I've washed it out a few times but it still continues to taint the water with a plastic taste. If you plan on using this for drinking water, DO NOT GET IT.

I wish I hadn't waited so long to use it as now I cannot return it.
