We only supply the highest quality replacement Darlly filter cartrdges to our customers. All Darlly filters come with high quality REEMAY filtration fabric, energy saving free flow cores, super bond bands and antimicrobial end caps.


Filter Warranty


Unlike any other UK company if you buy a filter from us & it happens to lose its integrity for any reason within 1 year, other than blatant misuse, ie extreme power-washing & have not followed Darlly's Cleaning & Warranty Guidelines, then we will replace that filter on their behalf without question. What's more, should the threaded part (often the weakest part of the filter cartridge) break within its life-time then we will replace the filter, no quibbles!
