Get the Best Quality Drinking Water right from your Faucet

4 Reasons why Everyone should use a Reverse Osmosis System

1. RO Removes Contaminants -> High Quality Drinking Water

High Quality Drinking Water


-  Around the world, reverse osmosis water purification systems are used to remove all kinds of contaminants from drinking water. 

-  Reverse osmosis systems work by passing pressurized water through a semi-permeable membrane, allowing pure water to pass through while rejecting the contaminants that are too large to pass through the tiny pores in the membrane.

-  The purified water coming out of a reverse osmosis system is virtually free of any contaminant that might have been present in the feed water

Below you will find a list of contaminants that can be removed by a simple (but extremely popular and effective!) under the sink reverse osmosis system

2. Reverse Osmosis Filtration Takes Care of Bad Odor

Experiencing unpleasant odors in your household water? 

RO filters take care of bad odor


-  If the bad odor occurs in ALL faucets, the problem is most certainly in the main water supply.

-  Contamination is THE cause of bad odor.

Unfortunately there are different types of contamiation/bad odor. Below you will find the most common types of odor problems.

Bleach, Chemical or Medicinal Odor

Public water suppliers (PWS) generally chlorinate water to prevent bacterial growth. Typical levels of free chlorine in drinking water from PWS are 0.2 - 2.0 parts per million (ppm), though levels can be as high as 5.0 ppm. In some cases, the high levels of chlorine may interact with organic materials built up in the plumbing system and add odor to the water. Some people who use water containing chlorine well in excess of the maximum residual disinfectant level could experience irritating effects to their eyes and nose. Drinking water containing high levels of chlorine can cause stomach discomfort.

Rotten Eggs, Decayed or Sewage-like Odor

Generally, a rotten egg (or sulfurous), decayed or sewage-like odor in household water is a result of bacterial activity. If the odor comes from the water source (e.g. bacteria growing in the well), it is not recommended to use the water because it may contain harmful bacteria unless it has been purified by an RO system!

Musty, Moldy, Earthy, Grassy or Fishy Odor

These kinds of odors may be due to pollution of well water from surface drainage. Although these odors are harmless, the human senses of taste and smell are extremely sensitive even at a very low level. 

Petroleum, Gasoline, Turpentine, Fuel-like or Solvent-like Odor

These odors may be due to:

-  A leaking fuel tank or underground fuel storage tank near your well
-  Discharge from factories or landfills contaminating the water supply
-  Run-off from agriculture contaminating the water supply

Even though these odor problems are rare, they are potentially serious. Stop drinking the water because it may cause several adverse health consequences, including but not limited to: Anemia, increased risk of cancer, liver and kidney problems

If any of these odor problems occur in your home, you should seriously consider an RO system!

-  Our Crystal Quest Whole House Reverse Osmosis Systems easily take care of any odor problem you might have.

3. Great Tasting Water as a Result of Reverse Osmosis Filtration

Great Tasting Water


-  Bad tasting water is often caused by high levels of total dissolved solids (TDS). They refer to any compounds left in the water after normal treatment and filtration. 

-  TDS in drinking water originate from natural sources, sewage, urban run-off, industrial wastewater, chemicals used in the water treatment process, and plumbing pipes.

- TDS can make your drinking water taste bitter, salty, or metallic. It often interferes with the taste of your food, beverages and ice cubes.


You can easily eliminate high TDS concentrations from your drinking water with a Nelsen 5-stage reverse osmosis system.

4. Using RO Filtered Water = Big Savings! 

Save money on drinking water

Cost Comparison: Bottled Water versus RO Filtered Water

Living heathy starts with drinking healthier water. Many health information resources have the same recommendation about drinking water: You should drink about eight glasses (64 ounces) per day. That adds up to 2 gallons per day for a family of four. When you use bottled water, the cost can be exorbitant. Let's assume you pay $6 per case (16 bottles) of 12-ounce water bottles (fancy imported waters can be much more), which is equal to $0.38 per bottle.

Annual Cost Bottled Water for a family of four:

$0.38 per bottle x 5.3 bottles per person = $2.01 x 4 people = $8.04 x 365 (days in a year) = $2,935

Let's compare that to the cost of using our Nelsen 4-stage Reverse Osmosis System, which costs $195 and requires new filters (cost: $45) only once per year, the membrane (cost: $49) needs to be replaced every 3 years. There is also the cost of water from the tap to consider, which runs about an average of $1.50 per 1,000 gallons in the U.S. A family of four consumes about 730 gallons of water (x 3 considering ro waste water) per year (6 gallons/day, 365 days/year), which amounts to $3.29.

Annual Cost for a family of four using a Nelsen 4-stage Reverse Osmosis filtration system:

1st year: $195 (system incl. filters) + $3.29 (water from the tap) = $198.29

2nd year: $45 (replacement filters) + 3.29 (water from the tap) = $52.29

3rd year: $45 (replacement filters) +$49 (replacement membrane) + 3.29 (water from the tap)= $97.29


That means that in 3 years time a family of four can potentially save $8,457.18* by switching from bottled water to reverse osmosis filtered water.

Stop wasting your money on bottled water, buy your own RO water filter system, be healthy and save a fortune!

*(2,935 x 3) – ($198.29 + 52.29 + $97.29) = $8,457.18
