Reverse Osmosis & Water Filtration Systems for Domestic Use
CALRO PRO
Smart direct flow Reverse Osmosis System
Reverse osmosis (RO) systems provide one of the most effective methods of water purification, removing up to 98–99% of dissolved contaminants including salts, metals, and impurities.
At Calmag, we supply high-performance reverse osmosis and water filtration systems across the UK.

WHAT IS REVERSE OSMOSIS?
Reverse osmosis is a filtration process that forces water through a semi-permeable membrane, removing impurities such as:
- Heavy metals
- Chlorine and chemicals
- Sediment and particles
- Dissolved solids (TDS)
This produces high-purity water suitable for demanding environments.
FEATURES
Eliminates more than 1000 contaminants
keeping your water safe from
chlorine, limescale, sediment, bad taste, heavy metals, odour, and also combats both chemical and organic contaminants such as arsenic, asbestos, benzene, fluoride, formaldehyde, nitrate, nitrite and trichloromethane.
Double Flow
Unlike traditional RO units, our RO Pro unit which has fast-filtering capabilities ensures a standard glass can be filled in 12 seconds due to the high water flow rate of the 600 gallon per day membrane.
Aquastop
The RO unit also incorporates a minimum pressure switch as a safety system, which protects the pump from pressure drops, stopping the RO unit and preventing its operation in a vacuum.
Comes with Smart Tap
Check the quality of the filters quickly thanks to the
multicolour LEDs:
- Filter working correctly
- Filter about to expire
- Filter needs replacing
When water is not requested through the smart tap, the RO unit stops operating by the means of a maximum pressure switch with an automatic
cut-off.
