We are currently selling three outstanding replacement gravity filters, two from the United Kingdom and one from the USA and meet some of the highest standards in the world. These filters are ideal with municipal town water, rain water and bore water. Replacement intervals can be as long as one year but six months is recommended for optimal purification. These filters increase the alkalinity of the water slightly and retain essential minerals including calcium, potassium and magnesium.

All these filters remove virtually all heavy metals, chlorine, cysts, bacteria, glyphosates, nitrates, microplastics, herbicides, pesticides and pharmaceuticals. They all work essentially the same way with an outer ceramic shell and activated carbon on the inside. The difference is with the proprietary absorbent materials used by the different manufacturers and the main dissimilarities are as follows:

(1) British Berkefeld (Doulton) ULTRA STERASYL® removes 99% of PFAS but not fluoride,
(2) KLT Filtration SCP FLUORIDE PLUS™ removes 97% of FLUORIDE but not pfas,
(3) Ceramic Filter Company SCP MAX™ removes 97% of FLUORIDE and 95% of PFAS.
