Water purification once seemed like a luxury reserved for those who demanded the cleanest-tasting water. However, with recent news about lead and other contaminants present in our tap water, water filtration has become a necessity for anyone who wants to know they have safe drinking water. If you want exceptionally pure water for your household, it’s time to buy an RO water purifier. These systems produce the purest possible drinking water of any at-home filtration option. RO, or reverse osmosis, is a purification technology that uses a special membrane to filter the water. This membrane is designed to mimic the osmosis that occurs on a cellular level. In cellular osmosis, a solvent like water is drawn across a semipermeable membrane to a region with a higher solute concentration. This allows cells to replenish their supply of water without absorbing any external contaminants. While cellular osmosis moves pure water naturally through a membrane where it can form a solution with the chemicals in the cell, RO takes a solution of water and other chemicals and uses pressure to push water through the membrane. This process creates pure water on one side of the membrane and leaves the water with a higher concentration of dissolved chemicals behind. To help imagine this process, if you took a saltwater solution on one side of the membrane and pure water on the other, the pure water would naturally flow towards the salt solution, attempting to dilute the solution through osmosis. Applying pressure to the salty side of the membrane helps to overcome the natural osmotic flow, allowing pure water to be extracted from the saltwater and leaving a concentrated brine behind. This is the basis of RO filtration, pressure helps overcome natural osmosis and removes pure water from a solution. Once a solution has undergone osmosis, the concentrated solution left behind is removed as waste and the process repeats. If you are interested in having one of these systems in your home, you can buy RO water purifiers here at efilters. We carry the ROM II, III & IV home RO filtration systems by Everpure. These amazing filtration systems feature Everpure’s user-friendly design combined with outstanding filtration power. These systems can be installed under your sink using simple hand tools. Once you install the filter head, storage tank, and connect the water lines, your new system will be ready to provide clean drinking water on demand year-round. The RO membrane is the key to providing superior water quality. These membranes can last for years, but they are surprisingly fragile. Chemicals like chlorine can punch holes in the membrane and large particulate can clog large portions of the filter. To avoid damaging the effectiveness of your RO system, all water is passed through an initial pre-filter cartridge. This cartridge will help absorb the chlorine commonly found in municipal water and filter out the larger particulate matter that would otherwise quickly foul the RO cartridge. The pre-filter cartridge will need to be changed approximately every 12 months to ensure your system functions properly. After passing through your pre-filter, your water will be filtered to approximately 0.5 microns. This filtered water then moves to the RO filter cartridge. Once pressure is applied and your water is forced through the membrane, it will be filtered down to 0.00001 microns. To offer some perspective, that is one five millionth the width of a human hair or one hundred-thousandth the width of a bacteria. Forcing water through this extremely fine membrane takes slightly longer than a standard carbon filter, which is why every RO system comes with a storage tank. This tank stores 3 gallons of RO filtered water so you can always have clean water on demand despite the filtration rate of 0.6 gallons per hour. If you choose to install the new ROMIV system, you will have one extra layer of filtration. This third filter cartridge is for filtering volatile organic compounds, also known as VOCs. While RO membranes have outstanding filtering power, compounds close to the size of water molecules can still slip through. The VOC cartridge helps to remove many of these residual contaminants to ensure that the water from your filtered water faucet is as pure as possible. No matter which of these RO systems you choose to install, you will be able to enjoy amazingly clean water on demand with minimal maintenance. The cost of RO water is also well below that of bottled water and it will also be far more pure, especially when you consider the effects of plastic leaching chemicals into bottled water over time. If you are ready to enjoy the cleanest water possible, now is a great time to buy RO water purifiers here at efilters.

Water filtration is something that most of us take for granted. Unless the water is coming directly from a natural source, we tend to not question whether or not it’s safe. Despite this sense of security, the water that comes out of your faucet is not always safe. Between chemical contaminants and microbes, there are a myriad of possible ways for water to become unsafe between the treatment plant and your home.

Water quality is no longer something to be taken for granted. The risk of chemical and biological contamination is ever-present and, in order to achieve a little extra peace of mind, homeowners are installing dedicated home water filtration systems. These compact systems fit beneath your sink and offer clean filtered water for months, if not years, between maintenance cycles.

NSF is a not-for-profit corporation founded in 1944 to promote good sanitation.  Its main business is to bring together experts in public health, manufacturing, and sanitation from government, industry, academia and the public to develop and administer performance standards for products which have some impact on sanitation and public health.  NSF maintains state-of-the-art laboratories where products can be tested according to the set standards.

Americans are fortunate to live in a country of great natural beauty and abundant resources. However, recent reports suggest that we need to take steps to protect these resources and that individual initiatives are essential to real change. Water shortages are a real concern, with wetlands disappearing and forest fires becoming more common. Fortunately, being eco-conscious doesn’t have to be complicated! Start at home with simple daily steps. 

Every human on this planet deserves to drink safe and clean water. Although we are blessed with vast water resources, humans have become the top contributors to water contamination. Because of our dream of industrialization and highly civilized living, we have taken for granted the importance of clean land, air, and especially water, which is crucial for human survival. We may have direct access to tap water in our homes, but it may contain hidden contaminants that can be harmful to our health.

Although the UN recognised it as a human right officially in 2010 , access to clean, safe drinking water is a privilege not afforded to everybody. According to the World Health Organization , there are currently 844 million people on the planet who can’t consistently access a clean water source.

The history of water filtration and treatment dates to more than 4,000 years ago. People who lived during these early times were exposed to various diseases, believing that any clear water was safe to drink. As water contamination continued to worsen, various types of water filtration systems emerged and were developed to provide humans around the world with safe and clean water.

Water is essential, invaluable, and precious. It is the one element we rely on every single day. Water is a basic human need for survival and an “ingredient” in almost everything we do, including food production, manufacturing, and power generation. Because water is so vital, it should be as clean and pure as possible, which is why filtration (e.g. using the Everpure H-300 cartridge) is important.
