Other brands of humidifier filters that we have looked at have a micro bacterial  core that keep algae from forming. Skuttle filters do not. We had a terrible experience with a Skuttle filter that was only 2 weeks old. There was a horrible odor coming from our vents when air was going through the filter. We had to replace the filter and it seems to be working fine now. Although, there is a smell to the Skuttle filter itself before using which is an odd smell. We could not find a filter other than Skuttle to fit the Skuttle brand humidifier installed by our furnace company.

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 thought that I was saving money by buying this set of 3 filters instead of buying 1 Samsung original filter for roughly the same price, but it turns out that I was wrong.  The second EcoAqua filter failed less than 2 weeks of use.  The water began dispensing progressively slower and slower after each use. I never had any issues with the Samsung filter which performed perfectly throughout my entire use and even after the refrigerator indicated for me to change the filter.  I would not recommend these buying these filters.  It is very frustrating when I have to stand at the fridge longer than I have to in order to fill my water bottle.

These filters are low grade and will not last long. Water and ice taste strange within two weeks after changing the filter.

I only used my vacuum a few times and the filter is already so filthy I can barely clean it. Although I guess it's doing the job, the other filters I've used lasted much longer.

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.

This replacement broke through it's clear packaging and was uncapped in the box.  I installed it and it was working great for a little over a month.  Now it is doing the same thing that the old one that was 2 and 1/2 years old did, slow the flow down to a trickle.  Very possibly it was caused because of poor packaging, bouncing around in the box and disrupting the membrane.  The filter is supposed to last 2 to 5 years.  My original that came with the system lasted over 2 1/2 years.

After 1 month of foul tasting water and ice, we finally had a repair man come out and tell us it was a bad filter.  We switched to the Whirlpool one at Lowes and it's fine now.

I ordered a 2 pack and the first one we used out of the pack was fine, but now we have replaced it with the second one in the pack and the water tastes like chemical. We've flushed out a lot of the water and it still tastes gross. Had the filter in now for 2 weeks and I am going to be taking it out and replacing it with a different brand.

Bought this on June 3rd and we are already having to replace it.  Water dispenser slowed to a slow trickle so we bought yet another filter and changed them out.  Now it is working fine. Hopefully for more than 2-3 month this time. We just don't use enough water to account for going through the filter that fast.  If this one goes out, I think we will just buy a bypass for the filter and be done with it!

I have bought this filter before from the same place ... but this filter is bad!!! And they are not cheap!!!!  It saddened me when I opened it to find this one bad because my first one back in Aug worked amazingly. ...

This filter failed and filled my cold water system with charcoal.  I had to pay a plumber to repair the problem.  The seller took the failed filter back but I had to pay $13 for shipping.  Not a good experience.

Worked great.. for about 2 weeks. Now the filter doesnt drain. Trying to stay away from paper filters but this is not a good alternative.

The filter works well but only for a couple of weeks. You must replace frequently.

I ordered these filters because of the price... hard to beat, right? Well I wish I would have bought a better one.

The filter was installed in my fridge and after only 3 weeks of use the flow was diminished by over 50%. So much so, in fact, that the ice machine stopped working because it couldn't fill the trays. As a benchmark - the normal whirlpool filter from HD never hit 50% flow after 3 months of use.

I just replaced it with the second filter and will update this review if this previous experience was a fluke.
