Frequently Asked Questions
What does “stages of filtration” really mean, and why is it important?
Simply put, it is how many different filters the water passes through. Each stage targets different impurities, and it is important because it helps remove a broader spectrum of contaminants for cleaner water.
What is the “pure-to-drain ratio” and why should I care?
It shows how efficiently the system makes pure water versus how much water gets wasted. For instance, a 2:1 ratio means that one part water is discarded to make two parts of purified water. A lower number is better for saving water and reducing your environmental impact.
Some systems have remineralization. Is that snake oil or actually useful?
RO filtration can remove beneficial minerals, so, some systems add them back in. It’s preference, but some like the taste better. Systems like the Bluevua ROPOT-Lite(UV) come with it!
Countertop vs. Under-Sink: Which style is better for my home?
Countertop models are easy to install – just plug and play! The under-sink models require a bit more plumbing work, yet they free up counter space. So, convenience or space saving?
What about maintenance, like filter changes? How often and how hard is it?
Filter replacement varies, but usually every 6-12 months. Some, like the Bluevua ROPOT-Lite(UV), offer quick, tool-free changes, while others might need a wrench and some patience.
