Reverse-osmosis systems, filters, replacement cartridges and pressure reducers for cleaner water and better-protected plumbing. Quality membranes and filters (Vontron) suited to Tunisia's often hard tap water. A range with regular refill cartridges to keep maintenance simple over time.

Tunisian tap water is often hard and chalky: a suitable reverse-osmosis system or filter improves the taste of your water and protects your appliances. Here's what matters before you order.
Before you buy
A membrane osmosis system (Vontron) removes limescale and most dissolved impurities for water close to bottled quality; a simple filter mainly catches particles and improves taste without treating water hardness.
Cartridges (sediment, activated carbon) are generally changed every 6 to 12 months depending on use, while the osmosis membrane (Vontron) is changed roughly every 2 to 3 years to keep filtration performance steady.
As a complement, a pressure reducer stabilises the flow entering the house, which extends the life of taps and appliances against excessively high pressure.
Frequently asked questions
If your water is very hard and you want a taste close to bottled mineral water, osmosis is more effective; if you mainly want better taste and to catch larger impurities, a simple filter is enough and costs less.
Cartridges are generally changed every 6 to 12 months, and the osmosis membrane every 2 to 3 years, depending on how much water you use and the quality of your tap water.
Yes, Vontron membranes are specifically designed to remove limescale and excess minerals, which suits regions in Tunisia where tap water is particularly hard.
Tunisia's hard water scales fast. Here are 5 tested natural methods to descale a faucet, aerator, and cartridge without damaging the chrome.
