Review on 💧 Enhance Water Quality with Culligan D 30A Filtration Replacement Cartridge by Heather Hale

I have used Culligan D30 and D40 filters in 2 homes, both fitted with wash down sinks with 2 or 3 cartridge assemblies. I change a pair every 6 months on a convenient schedule using the Revain subscription service. They come and get dressed. No need to write in the calendar when to replace. A pair of D30 and D40 eliminates every hint of chlorine taste/odor. D40 is said to remove lead etc but I haven't tested my water for it. Not only do I use this for drinking water, cooking, I also use it for my two 70 gallon. aquariums. I change about 25% of the water every 2 weeks and don't use a chlorine/chloramine remover. So far so good, 15-year-old Pisces are happy and healthy (and huge, by the way!)
