Frequently Asked Questions

We've included a list of FAQs for a wide variety of categories.

How does a 4-stage ultrafiltration system improve water?

The Brio 4-stage system uses multiple filters to give your water a higher level of purification. After sediment and GAC (granular activated carbon) filters remove particles, chlorine, VOCs (volatile organic compounds), and other harmful chemicals, water passes through an ultrafiltration membrane, which blocks bacteria such as E. coli, viruses, and major contaminants. A final carbon filter polishes the taste and reduces any remaining impurities. The Brio 4-stage system delivers premium-quality water while preserving minerals your body needs.

Will my water taste significantly better with a 4-stage bottleless cooler?

You’ll probably notice a big difference. The 4-stage system removes contaminants that give water an odd taste, especially chlorine or metal. What’s left is cleaner water with no aftertaste. It’s perfect for serious hydration and also works great for cooking, coffee, tea, or just sipping throughout the day.

How does a 4-stage bottleless cooler differ from other filtered water coolers?

Compared to 2- or 3-stage systems, a 4-stage bottleless cooler adds ultrafiltration. While 2- and 3-stage systems remove most chemical contaminants, the 4-stage filter blocks things like bacteria and fine particles that smaller systems might miss, and without removing helpful minerals. The result is safer, cleaner water with great taste. Brio 4-stage bottleless coolers also feature post-carbon filtration to polish the highly filtered water and remove any residual impurities.

Brio 4-stage coolers are easy to set up and simple to maintain with intuitive filter replacement. No bottled water needed. They’re perfect for high-traffic spaces like shared offices, kitchens, and breakrooms where water quality and hygiene matter. With self-cleaning included and a sleek design, a 4-stage bottleless system delivers powerful filtration that’s easy to use.

Is mineral content affected by 4-stage filtration?

No, ultrafiltration systems are designed to keep healthy minerals like calcium and magnesium in your water. The fine membrane removes bacteria and other microscopic contaminants like viruses, but it doesn’t strip the water of its natural mineral content. That’s one reason some people prefer it over reverse osmosis, which removes almost everything. Ultrafiltration provides safe, better-tasting water with the minerals you need for health and hydration. It’s a powerful purification process that enhances your water without the need to replace necessary nutrients.
