What contaminants are removed?
How does 4 stage reverse osmosis work?
The Four Filtering Stages
Sediment Pre-Filter
The first stage of the 4-stage reverse osmosis water filtration system involves a sediment pre-filter. This pre-filter filters out the most basic of water contaminants, including dirt, dust, and other large, obvious debris.
This pre-filter is especially necessary for those who get their water from a well or a spring. Water that comes from these sources is almost guaranteed to be contaminated with at least small traces of dirt or sand.
Carbon Pre-Filter
The next step in a 4-stage reverse osmosis filtration system involves a carbon pre-filter. Eliminating several components from the water, including lead as well as tastes and odors that stem from the presence of chlorine, this stage serves to neutralize the water so that it tastes pure and free of chemicals.
Reverse Osmosis Membrane
The key stage in a 4-stage reverse osmosis water filtration system involves a reverse osmosis membrane. This membrane is capable of eliminating 95% of all dissolved solids from your water, softening it, and giving it as smooth a consistency as possible. After the water has passed through this membrane, it will be almost completely free of contaminants.
Post Carbon Filter
The last stage of a 4-stage reverse osmosis system makes use of a post-carbon filter. This filter is the last line of defense against any contaminants that might still be passing through your water after the first 3 steps of the process.
Known as the “polishing” filter, it remains any additional taste that may remain as a result of chlorine, lead, or iron. After this step has been completed, your water will be purified and ready for drinking.

Located in the Piedmont region, it is the county seat of Mecklenburg County. Its modern city center (aptly name “Uptown” because no matter which way you walk toward independence square, you’ll be moving gently upward) is home to the Levine Museum of the New South, hands-on science displays at Discovery Place, and the NASCAR Hall of Fame. First as a railroad junction and then as a cotton mill hub, today it is one of America’s largest banking centers and one of the nation’s fastest-growing metropolitan areas.Charlotte looks like a brand new city, but there’s a lot of history here. Its roots run deep in the Old South, way back before the American Revolution. Late in the Revolution, British General Cornwallis swept into town during the 1780 Battle of Charlotte and the Battle of Kings Mountain but soon wished he hadn’t. Local sharpshooters peppered his men mercilessly and as they departed it is said that Cornwallis wrote in his diary that Charlotte was a “hornet’s nest of rebellion.” Today, the hornet and hornet’s nest are popular civic symbols.Directions: Directions from Charlotte Douglas International Airport to Marathon Resources: Get on I-485 Outer from Old Dowd Rd and Wallace Neel Rd, Head south on Josh Birmingham Pkwy, Keep right to continue on Old Dowd Rd, At the traffic circle, take the 1st exit and stay on Old Dowd Rd, Continue onto Wallace Neel Rd, Turn right onto West Blvd, Turn left onto the I-485 Outer S ramp to Pineville, Follow I-485 Outer to US-521 S/Johnston Rd in Charlotte.
