Description
APEC RO-90 (Under-sink tank RO system) is supplied by Clean Eco Trade to homes, businesses and contractors across Oman, from our base in Seeb, Muscat.
Why it suits Oman
An under-sink system keeps drinking water off the counter and out of sight, which matters in smaller Omani flats and kitchens where space is tight. The things to check before buying are cabinet clearance, feed pressure and whether the model needs a power point. We confirm all three from a photo of your sink cabinet, so there are no surprises on installation day.

Frequently asked questions
What are the key specifications of the APEC RO-90?
According to the manufacturer’s published data: capacity 90 GPD; stages 5; tank 4 gal. The full list is in the specifications table above, and we are happy to confirm whether it suits your site before you order.
Does it need electricity?
Some systems are fully mains-pressure driven; others use a booster pump and need a nearby socket. Check the specification list on this page, or ask us, and we will point out any power requirement and the best place to put the plug.
How often do I change the filters?
Pre-filters are usually changed every six months, and the RO membrane every two to three years, shorter in hard-water areas. We keep a record of your installation date and send a reminder before each service is due.
