Water production

The water output of the system differs from one household to other. The water production depends upon the water pressure and the temperature. With the normal municipal water pressure, APEC RO-90 produces 75 gallons a day. While at the pressure of 60 psi, it reaches its maximum level of water production of 90 GPD.

Water efficiency

Like APEC ROES-PH75 this under counter water system also wastes 3 gallons of water to produce a single gallon of purified water.

This wastage of water is associated with every Ro-system. You can’t have a gallon of purified water without that wastage. The most important take away point is that you can utilize it in gardening or in any other cleaning task.

This water waste ratio is acceptable as it is better than most of its rivals in the market.

Filtration system

APEC RO-90 filtration process is exceptionally good, can remove 99% of contaminants from the water. It has 5 stages filtration process but still, performance is remarkable.

Most of the customers think that more filtration stages mean more purified water, but it is the wrong perception. The competency, effectiveness and most importantly the quality of components are factors to consider before moving towards filtration stages.

APEC RO-90 is designed by considering all these factors and even the filtration stages are unchallengeable. Because the filters are of high quality and NSF certified.

Instead of initial cost, maintenance cost is the more concerning point. APEC knows RO users other than anyone else. APEC RO-90 filters are long-lasting and of high quality. The longer lifespan of filters reduces your maintenance cost.

Mostly RO-system filters replaced after every six months. But APEC RO-90 Pre-Filters are needed to be replaced after every 12 months. Even filters serve efficiently for at least 90 days without being replaced. Post filters and RO membrane are required to be replaced after 3-4 years.
