As we know, that the water is important in our daily lives. Used for bathing, washing or to wash raw food and the most important is to drink.

Over two-thirds of our body consist of water and we must drink at least 2 liters per day to keep the body healthy and fit and avoid dehydration.

But, are we sure that the water available in the home has pure clean and wholesome to use?.

Use the best reverse osmosis system for your home, so you are sure that the water used is clean and healthy. 

Best reverse osmosis system is a cheaper alternative to the distillation process and according to the US Center for Disease Control, a reverse osmosis system will remove:

  • Sodium - at higher levels will contribute to hypertension in some individuals.
  • Chloride - Make water taste salty or brackish.
  • Copper - can cause digestive problems and in the long-term can cause liver and kidney damage.
  • Lead - can cause a significant decrease in physical and mental development in children, while in adults, can cause increased blood pressure and kidney problems.

Besides, a reverse osmosis water filter can (depending on the quality of the systems you use) reduced:

  • Arsenic - This odorless and tasteless element, perhaps without you even knowing, is in your drinking water. This can cause disorders of the bladder, lung, kidney, liver, prostate and other cancers.
  • Fluoride - According to a study by the American Dental Association, it has proved that using excessive fluoride can cause teeth and brain damage.
  • Radium - long-term, radium will increase the risk of lymphoma, bone cancer, leukemia and aplastic anemia.
  • Sulfate - based on human studies conducted by the World Health Organization, show that increased sulfates in drinking water not only give water a bad taste, it also causes diarrhea.
  • Nitrates - Dangerous for the baby can develop blue baby syndrome and shortness of breath.
  • Phosphorus - It is a natural occurring element and in its white form as rat poison. When humans digest it, they may experience nausea, drowsiness, and even death.

Home Master TMAFC Artesian Full Contact Undersink Reverse Osmosis Water Filter System Review

Maybe, you already know for a fact the health benefits of alkaline water, such as may help slow the aging process, regulate the pH level of your body, and can prevent chronic diseases such as cancer.

But, what exactly is the alkaline water?.

Alkaline water is water that is less acidic than ordinary tap water. Rich in alkalizer compound, including calcium, silica, potassium, magnesium, and bicarbonate.

Where, alkaline water can neutralize acid in your bloodstream and helps your body metabolism of nutrients more effective, which contributes to health and better performance.

Tap water containing dissolved different elements that have an impact on the pH level. Pure water has a pH level close to 7, while the alkaline water has a pH above 7.

The Watts Premier RO-Pure 4 Stage Reverse Osmosis System is the best reverse osmosis system under $200.

What is Reverse Osmosis?

Reverse Osmosis or also knew as RO System is a water purification technology using a semipermeable membrane, which removes ions, molecules and larger particles from the water.

A semi-permeable membrane is a membrane which will allow atoms or molecules to pass but not others.

A simple example is a screen door. Wherein, the air molecules can go through but not a threat or anything bigger than a hole in the screen door.

In the reserve osmosis technology, pressure is  implemented to overcome the osmotic pressure. This process can rid of various types of ions and molecules of water, such as bacteria.

During the process, the solute is retained on the pressurized side of the membrane while pure solvent on the other side of the membrane.

How Does Reverse Osmosis Work?

Reverse osmosis works by using a high-pressure pump to raise pressure on the salt side of the RO and forcing water across a semipermeable membrane RO, leaving most all (approximately 95% to 99%) of dissolved salts behind in the stream.

The pressure required depends on the concentration of salt from the water. The more concentrated the water, the more pressure needed to overcome the osmotic pressure.

Desalinated water is  demineralized or deionized water, called permeate (or product) of water.

The flow of water carrying concentrated contaminants that do not pass through the RO membrane called a rejection (or concentrate) stream.

RO System

It is important to realize that the RO system employs cross filtration rather than standard filtration, where contaminants are  collected in the filter media.

With cross filtration, the solution goes through the filter, or across the filter, with two outlets: the filtered water goes in one direction and the contaminated water goes the other way.

To avoid a build-up of contaminants. Cross-flow filtration allowing water to sweep contaminants builds up and also allow enough turbulence to keep the membrane surface clean.

How to install Best Reverse Osmosis System

How to Test Reverse Osmosis Water Quality?

To check the quality of water produced by the best reverse osmosis system you use, using TDS meters. It is important to know the effectiveness of the membrane and when it’s time to replace the membrane.

A TDS meter show Total Dissolved Solids (TDS) is the total amount of mobile charged ions, including minerals, salts or metals dissolved in a volume of water, expressed in units of mg per unit volume of water (mg / L), also known as parts per million (ppm).

TDS is  related direct to the purity of water and the quality of the water purification system and affects everything that consumes, lives in or uses water, whether organic or inorganic, either.

These video shows how to use a TDS meter to test the quality of water you use.

To calculate the results of the TDS meter, you can use this TDS Calculator, wherein if the results show a 100% – 80%, it means that the membrane still works effective, while if the result is below 80%, it means that it’s time to replace the membrane you use.

How to Maintain Your RO System for Best Performance

A best reverse osmosis system will go on for years if maintained proper. To make your RO System, the last longer, do some of these tips:

1. Regular Filter Changes

First, attention the filter replacement schedule recommended in the manual RO systems you use.

RO system you may have three, four or five stages, to know exactly what the filter at every stage of your system (per the owner’s manual) and attention when each filter is scheduled for replacement.

2. Sediment Filter

Sediment filter should be changed every 12 months. Pre-filter is used to strain out sediment, mud, and dirt.

This sediment filter is important for protecting the dirt into the RO membrane.

If you are just too late to change the filter is on schedule, dirt and mud can reach the RO membrane which will make it become clogged and foul.

3. Carbon Filter

This filter should be usually replaced every 12 months.

Carbon filters are designed to get rid of chlorine and other contaminants that affect the performance and life of the RO membranes and the taste and odor of your water

4. Reverse Osmosis Membrane

Semi-permeable RO membrane in the best reverse osmosis system you use, enable water through but filter out almost the contaminants.

If you replace the sediment and carbon filter under the schedule, the RO membrane only must be replaced every two to three years.

Schedules will vary based on the quality of water use and water your household.

5. Polishing Filter

In the four-stage RO system, the last filter is a “polish” of water to remove residual taste and odor in the water.

The final filters to make sure you will have a tremendous drinking water.

So, make sure that you change all the filters and RO membrane by the schedule, to make your best reverse osmosis system remains durable and produces excellent water quality.
