What Is Reverse Osmosis?Reverse osmosis works by having a high water pressure on the incoming supply side of a semi-permeable membrane within the water filter. This causes the water molecules to pass through the membrane leaving behind salts and other contaminants that were in the water and resulting in purer water on the resevoir/tap side with the rejected water containing the impurities being discharged in to the drain. A properly functioning RO system will normally achieve a reduction of between 94-99% depending on the impurities concerned (see below).[The capacity of the membrane is expressed as GPD which means Gallons Per Day]

How do Reverse Osmosis Water Filters Work?Filter 1) The sediment filter is the first stage and removes particles and suspended sediments and particles to 5 micron. Filter 2) The Pre-carbon filter then removes dissolved gases and heavy metals. Filter 3) The RO Membrane removes impurities to 0.00001 Microns. It does not store them in the filter but washes the impurities down to drain. Step 4) Purified water is stored in a 10 litre storage tank. Filter 4) The system automatically shuts off when the tank is full and then passes through a final post carbon filter to provide taste and odour optimisation for the finishing touch. Other post filters can be used to further condition the water for optimal health, such as alklaine ionisation, negative oxidation and micro-clustering. |

A concern that is sometimes raised over reverse osmosis water filtration is that this method also results in the beneficial minerals such as calcium & magnesium being removed along with the undesirable elements. There is considerable debate as to how important an issue this is with claims varying from it being a major health concern to being of no consequence. In response to this issue many reverse osmosis systems on the market now include alkaline re-mineralising filters which ensure that any beneficial compounds removed in the purification process are replenished, giving you the best of both worlds and the best tasting, healthiest water possible.
Types of Reverse Osmosis Systems
Most RO systems offered for sale will include a tank which is located under the counter and holds the purified water until required. There are some reverse osmosis filters however which are known as ‘direct flow’ which have the capacity to, as the name suggests, provide a direct flow of purified water from the filter unit to the tap. The main benefit of such systems over the standard type is fresher water and space saving as they do away completely with the need for a storage tank. Such systems include the excellent Osmio HT+ Home & Office RO Filter with smart water functions.
For those who want enjoy the advantages of reverse osmosis but are regularly on the move, in rented accomodation or don’t want to be bothered plumbing in a RO system there is now the option of the countertop Osmio Zero Installation Reverse Osmosis Water Filter requiring nothing but an electrical socket. This innovative and stylish kitchen worktop RO filter will supply ambient, warm, hot & boiling purified water at the touch of a button and can completely replace the kettle.
Another factor to consider is your home’s water pressure ~
Do You Need a Pumped or a Non-Pumped System?
If you have normal to high water pressure of 3 bar or more, then you should use a non-pumped system. If your water pressure is lower than 3 bar or you are not sure, we recommend you use a Pumped system.
Pumped reverse osmosis systems come with a normal UK 3 pin plug and just need to be plugged into a nearby electrical socket. If you have any appliances (dishwasher, washing machine etc) next to your installation area (usually under the kichen sink), then it is normally very easy to find a plug socket there. Pumped systems are very quiet and very low power. We can also supply stand alone pumps for upgrading existing RO systems.
