British Berkefeld 7 Inch Ceramic Ultra Sterasyl Gravity Replacement Filter (NSF Certified)

Very effective

I draw Ayer from a shallow tiled well and this filter has allowed me to safely drink it I have been using them for 26 years.

The company is good. Two 7" filters are slow and do not keep water enough for even one person.

Great filters and great customer service

I had a great experience with this company, I had to exchange some filters as I purchased the wrong ones by mistake and it was a very easy process. I would definitely buy from them again.
