Product review (2 stars): Zuma water filter - decreased water flow and humming sound during 4+ months of use
I purchased and used this filter for almost 5 months. I noticed when I first installed the filter in my refrigerator, my water dispenser began making a humming noise and the water pressure dropped significantly. I assumed the sound would eventually subside and the pressure would increase. Unfortunately, the problems never corrected themselves. After a few weeks, I removed the filter and reinserted it thinking that may correct the problem. That only made it worse. After 4 months, the water flow in the dispenser slowed to almost a trickle and the ice maker no longer made ice. I have never had this problem with any other water filter (name brand or generic) and therefore concluded it was this particular brand and/or model. This week I replaced the filter with a different brand. The humming sound immediately stopped. the water flow increased by 10x, and the ice maker starting churning out ice again. I definitely don't recommend this filter. I always try to purchase Made in USA and eco-friendly products when possible, but unfortunately, this product doesn't meet even a basic level of quality.
