Review on ISpring FC25B High Capacity 🚰 Carbon Filter: Enhanced Filtration and Long-lasting Performance by Pamela Smith

I have recently purchased and had this filter installed as regular replacement (after 10 months) for my iSpring WGB22B water filter. The original filters (cartridges) ran great but the new Carbon filter caused my water pressure to drop to unacceptable levels. I wrote to iSpring and Don, iSpring's customer service rep, called me the next day, helped me diagnose the problem, and provided me with a filter replacement. He had been very patient and helpful, even in these difficult (coronavirus caused) times. He pointed out that it's extremely rare for filter cartridges to cause problems. I will update the review once the replacement arrives and is installed.
