Safe Water For the Ones You Love

•Save on your water bill - the filters won’t produce any wastewater.

•Official 2nd stage filter for iSpring whole house water filtration system WGB21BM. Fits standard 10” x 4.5” filter housings.

•Unlike an RO membrane, the iron and manganese filter doesn't reduce Total Dissolved Solids (TDS). If you are interested in a filter that removes TDS, consider our iSpring Reverse Osmosis (RO) systems such as RCC7 series and tankless RO systems like RO500.

Great product

I am using three of their house filters and they work amazingly. They are also very helpful when you talk to them on the phone. Would recommend highly using their product.
