4-Stage RO

A 4-stage reverse osmosis (RO) system uses four separate filters to remove impurities from tap water. The first stage prepares the water for reverse osmosis by using a sediment filter that removes the largest particles, such as silt, rust, and dirt. The second stage is the pre-carbon filter. This stage reduces chlorine, odors, VOCs (volatile organic compounds), and other chemicals. Next, the RO membrane removes dissolved solids, including heavy metals like lead and arsenic, and also filters out bacteria and viruses. A post-carbon filter puts the finishing touch on the water, removing any additional impurities that affect taste and odor.

This multi-stage process provides complete water filtration and extends the effectiveness of each specialized filter. With a 4-stage RO system, you get enhanced protection compared to standard filters, resulting in cleaner, safer water for everyday use.

Reverse osmosis (RO) uses pressure to force water through a semipermeable membrane, which filters out contaminants. Before reaching the membrane, however, water is prepared by preliminary filters, including sediment filters and GAC (granular activated carbon) filters. Together, these filters remove silt, dirt, chlorine, VOCs, and other substances that cause unpleasant tastes and odors.

The water then passes through the RO membrane’s extremely tiny pores, about 0.0001 microns wide, which trap impurities while allowing water molecules through. Contaminants, such as lead, arsenic, PFASs (synthetic “forever chemicals”), bacteria, and viruses, are discarded in wastewater called brine or concentrate. The purified water then moves to the final step of filtration, often a coconut carbon block filter, which removes residual tastes and impurities.

The end result: safe water for pure refreshment.

Reverse osmosis (RO) has numerous advantages over plain tap water. It removes a wide range of contaminants that ordinary carbon filters cannot, including lead, arsenic, nitrates, bacteria, viruses, PFAS, and many other harmful substances. RO systems also improve the taste and clarity of tap water by reducing chemical residues. Odors are also reduced. With a multi-stage filtration process, you get clean water and consistent results.

RO water is ideal for drinking, cooking, and making beverages like coffee or tea — pure water means pure flavor. Another advantage is that many of the Brio RO dispensers include self-cleaning features that make maintaining hygiene easy. Water purified by reverse osmosis also reduces the need for bottled water, which cuts down on waste and saves money. Best of all, you can rest easy knowing you’re not consuming dangerous contaminants.

Whether you’re filtering municipal tap water or well water, reverse osmosis is a powerful, reliable way to improve your water at home or on the job.

Reverse osmosis (RO) systems remove numerous contaminants, including lead, arsenic, fluoride, chlorine, nitrates, sulfates, and other dissolved solids. They also reduce pesticides, herbicides, volatile organic compounds (VOCs), PFASs (synthetic “forever chemicals”), bacteria, viruses, and microbial cysts. The semipermeable membrane, with pores as small as 0.0001 microns, makes RO one of the most effective filtration methods available.

Reverse osmosis water has a cleaner taste compared to standard bottled water. By removing dissolved substances like minerals found in some spring waters, it has a neutral taste that’s perfect for hydration, coffee, tea, and cooking. And, since RO systems remove chlorine and chemical residues, the result is fresher-tasting water.
