Product review (1 stars): Avoid this brand.
I bought a twin pack of these and at first everything was just fine but after I noticed that the water in the door was flowing more slowly. Then it kept slowing down... a lot.  After about 2 months of use it is now so slow it would take about three minutes to fill a glass of water.

I replaced the filter with the 2nd filter purchased and the flow is back to normal (15-25 seconds to fill a glass).

After checking the filters and packaging I can find no company contact information.  I googled them and can find nothing and since I am now past the 30 day Amazon return period I have no way of getting a refund or replacement.  It is very disappointing that in today's world a company has no website or contact information available on the web (there is another EcoAqua but doesn't appear to be the same company - different logo, different products).  Very shady.

The best that I can say about the filters is that they are cheap.  I guess you get what you pay for.  We will see if second filter  lasts any longer than the first,  but I I'll avoid this brand in the future and can't recommend them at all.
