About Osmotics
Osmotics Ltd is a water purification supplier in Aylsham, Norfolk, selling reverse osmosis systems, filters, membranes and the parts that support them. Residential, commercial and aquarium customers all appear on its list, and the range covers 3, 4 and 5-stage reverse osmosis systems, drinking water systems, aquarium RODI units, whole house systems and undersink filters. Cartridges, sanitizers, storage tanks and TDS meters sit alongside those units, so a domestic user setting up a first system and a commercial buyer sourcing replacement parts both have somewhere to look.
Reverse osmosis forces water through a semi-permeable membrane that holds back dissolved salts, minerals and other impurities, which is why the same method works for a household drinking water unit and for the top-off water a reef aquarium needs. Osmotics leans on that technology for clean, safe water while also covering specialised jobs where filtration has to be precise.
Visa, Mastercard and PayPal are all accepted for payment. Standard shipping costs nothing on orders over £200, and anything below that has its delivery rate worked out at checkout. Military discounts are open to UK customers who verify their service through the Defence Discount Service.
