What’s the difference between whole house filtration and reverse osmosis?

Whole house filters are designed for general water treatment throughout your home. They reduce sediment, chlorine, VOCs, and odors. They also remove or reduce minerals, which protects plumbing and improves water for daily use.

Reverse osmosis (RO), on the other hand, is a more advanced, point-of-use system that removes a broader range of contaminants, including dissolved solids, heavy metals, and certain bacteria and viruses. RO systems are typically installed under a kitchen sink or in a dedicated dispenser. They’re ideal for cooking and drinking water. Many households use both a whole house system for general filtration and RO for purified drinking water.

Do reverse osmosis systems waste water during filtration?

All reverse osmosis systems create wastewater as part of the filtration process. The RO membrane separates the contaminants from the permeate, or clean water. The RO system then flushes the contaminant-filled water, or brine, down the drain.

In many traditional tank systems, the ratio of pure to waste can be as high as 1 cup of pure water to 5 cups of wastewater. However, newer systems, including Brio
SIMPL and AQUUS, are designed to be much more efficient and waste less water.

How do you choose the right reverse osmosis system for your home?

Identify your specific water problems. If you’re concerned about lead, chlorine, or PFAS, be sure the system you choose can reduce these contaminants. Brio tankless RO systems, for example, offer advanced multi-stage filtration that covers many water quality issues.

Next, consider the number of people in your household. How much filtered water do you need for drinking, cooking, or making coffee and tea? For most households, this adds up to a few gallons per person per day.      

Now, think about this: tankless systems are great for saving space under the sink. Traditional RO systems with tanks may be better suited to homes with high water use or limited water pressure. How important is space-saving to you?

Also, be sure to examine features like filter life, maintenance, and any options that are important to you. Finally, consider installation. Some systems are DIY-friendly, while others may require professional help.

Choosing the right RO system means balancing performance with convenience and the specific needs of your home.

How exactly does a reverse osmosis system work?

A reverse osmosis system purifies water by forcing it through a semi-permeable membrane with pores only 0.0001 microns in diameter. The membrane blocks contaminants while clean water molecules pass through. Most systems include multiple stages of filtration, starting with sediment and carbon filters that remove
larger particles, chlorine, and bad taste.

The RO membrane filters various contaminants and dissolved solids, such as arsenic and lead. Finally, a post-filter polishes the water for a clean, crisp taste. Some systems also include UV or remineralization stages for added protection or better flavor.

This multi-step process produces water that’s much cleaner than standard tap water. RO systems are considered the most effective option for home use.

Why are people switching to reverse osmosis water?

People are installing reverse osmosis (RO) filtration systems more than ever. It’s mainly because RO filtration systems offer the highest level of purification available for home use. RO systems reduce a long list of contaminants like lead, PFAS, nitrates, and even bacteria and parasites. Your water tastes cleaner, and it’s safer to drink. It’s no surprise people are switching!

People are also more aware of what’s in their water thanks to growing concerns about chemical pollution. Reverse osmosis gives you control over your water quality
without relying on bottled water or expensive delivery services.

With modern designs like tankless systems, RO filtration is now more efficient and accessible than ever.

Which contaminants can reverse osmosis systems filter out?

Reverse osmosis (RO) systems remove many contaminants, including lead, arsenic, fluoride, chlorine, nitrates, PFAS, and dissolved solids. RO is the most effective filtration available for home use.

What does “pure-to-waste ratio” mean in a reverse osmosis system?

Pure-to-waste ratio indicates the proportion of filtered water produced versus the amount discarded. A 2-1 ratio means 2 cups of clean water for every 1 cup wasted.
