FAQs for Reverse Osmosis Systems

How does reverse osmosis work?

An RO membrane separates part of the incoming water into filtered water and a reject stream. Actual performance depends on the system, source water and operating conditions.

Which system fits my home?

Compare dimensions, installation requirements and operating limits. Countertop and under-sink models have different setup needs.

What does the system reduce?

Consult the exact model documentation for tested reduction claims. A certification for low lead content does not certify contaminant removal performance.

Does an RO system produce drain water?

RO filtration produces a reject-water stream. The ratio varies by model and operating conditions; use the stated model specification when comparing systems.

Which replacement filters should I buy?

Match the system model and cartridge code. Check the product listing for the included cartridges and compatible spares.
