Frequently Asked Questions

How often do I need to change the filters?

Filter life varies by model and water quality, but generally, pre-filters should be every 6-12 months, and the RO membrane every 2-3 years. The APEC ROES-50 includes extra pre-filters, which may extend the lifespan. Regular replacement is vital to maintain water purity.

Are these systems difficult to install myself?

Some, like the Express Water RO5DX with its color-coded tubing, are designed for easier install. Others, such as the 100 GPD Home RO System, get the best outcome when installed professionally. The Bluevua RO100ROPOT-LITE circumvents installing it altogether.

What does “GPD” mean, and how much do I need?

GPD stands for “gallons per day” and indicates how much purified water the system can produce. For small households, 50 GPD is often fine. Larger families might be better suited to a 75 GPD or 100 GPD system so everyone has access to purified water at all times.

Is there a system that adds minerals back into the water?

Yes! The iSpring RCC7 has a mineralizer add-on option. Adding minerals can make the water taste better.

What about water waste? Are these systems environmentally friendly?

RO systems do produce some wastewater. Some models have a better pure-to-waste ratio than others. The Bluevua RO100ROPOT-LITE has a 3:1 ratio, meaning it wastes less water than a system with a lower ratio.
