What is Reverse Osmosis

Reverse osmosis is one of the most effective methods of filtering the tap water in your home. Reverse osmosis technology is designed to remove a great percentage of the contaminants in your drinking water by filtering the water through a semipermeable membrane.

Reverse osmosis filters are one of the main types of water filters trusted by commercial businesses and private homeowners alike. Reverse osmosis filtration systems are among the most popular options because of the large amount of potential contaminants that the process removes. Other types of popular water filters include UV filters, infrared filters, water ionizers, and carbon filters. Many technologies within these types of filters overlap - for example, our 6-stage reverse osmosis water filter contains a carbon filter, and deionizes tap water in a manner similar to that of other filters.

 

At its most basic, reverse osmosis is a process through which inorganic solids, like salts, are removed from an aqueous solution, like your tap water. The water in your tap is pushed through a semipermeable membrane, which filters out many contaminants and impurities that can find their way into your drinking water.

“Reverse osmosis” can often sound like scientific jargon, so let’s break down that phrase to demystify the actual process. First, we should outline the natural process of osmosis as it occurs in nature.

Osmosis

Osmosis is one of the most important processes to occur in nature every day. Osmosis occurs when weaker saline solutions migrate to stronger saline solutions. Or, put simply, when water with fewer particles or impurities moves naturally to adjacent water with more particles and impurities. An example of this in the real world is when your kidneys absorb water from your bloodstream - the water in your blood moved to the denser area of your kidneys.

Less concentrated solutions will always migrate to more concentrated solutions if possible. A semipermeable membrane allows small particles like water to pass through, so if you separated a solution with low salt content and a solution with high salt content by placing a semipermeable membrane between them, the solution with low salt content would pass through the membrane and fill the solution with high salt content until their densities were equal.

Semipermeable Membrane

What, exactly, is a semipermeable membrane? The technical definition is a barrier through which some particles can pass through, but others cannot. Some great examples in real life would be a sponge, a fisher’s net, or a screen door. While air can flow through your screen door, a bird certainly could not.

Reverse Osmosis

So, then, reverse osmosis is exactly that: reversing the process of osmosis to push solutions with a higher concentration of particles through a semipermeable membrane to remove unwanted particles and contaminants. Because of the way the process works, a particle’s size determines whether or not it will remain in your tap water once it’s pushed through. Some reverse osmosis filters can remove particles that are as small as .001 microns.

How can the process of osmosis be reversed? By applying concentrated energy to the solution (in this case, the tap water being directed into the filter). Reverse osmosis filters like those sold by Pelican Water apply a great deal of energy to your tap water to pass the water through a semipermeable membrane and remove the contaminants within. This process will desalinate the water and block many contaminants from remaining in your water. The process of desalinization (removal of salt) can also be referred to as demineralization or deionization (removing minerals or certain ions from your water).

Multiple processes occur within a reverse osmosis filter that leave you with crisp, refreshing drinking water with most impurities removed in a matter of moments.

What Is a Shower Filter?

When it comes to water filtration, most consumers automatically associate filters and water treatment products with drinking water. This connection is natural - the water we drink every day should be properly filtered and free of contaminants so we drink pure, refreshing water without any unwanted side effects or health problems.

But did you know your body also absorbs water while you shower? The water you bathe in affects the overall quality of your skin and hair. Your skin is the largest organ of your body, and if you shower for 10 minutes per day the potential chemicals in your shower water could irritate your skin and damage your hair.

Most homeowners aren’t aware of the dangerous chemicals present in their shower water. Quite frankly, our drinking water tends to get all of the attention! But in order to fully filter the water in your home, you should consider investing in a shower filter. A shower filter is installed right at the shower head, so the water is treated before it reaches your skin. Most shower filter systems come with their own shower head, but some systems only include the filters.


How Does a Shower Filter Work?

Shower filters are similar to drinking water filters in their core mechanics: they are comprised of a series of filters, or stages, where the water passes through various substances in order to remove or convert chemicals like chlorine into non-harmful alternatives. Shower filters often contain multiple stages. Let’s explore the inner-workings of a shower filter further:

Stage 1 - Copper and Zinc Oxidation Media

The first stage, indicated in the goldish hue in the diagram, Includes a patented blend of media like copper and zinc to filter chlorine and other contaminants from your shower water. Removing chlorine, as we’ll discuss below, benefits your hair and skin in numerous ways.

Stage 2 - GAC Carbon Media

The second stage, illustrated in the diagram as the blackish-grey section, incorporates a special blend of steam activated carbon media. You may have heard of carbon filters in relation to drinking water filters, and in fact many brands of shower filters are solely carbon filtration systems. The carbon media in this stage is designed to filter out chloramines and synthetic chemicals as well as unpleasant odors. Your water will smell fresh and clean after passing through the carbon media. Only some brands of shower filters include carbon filtering: check specific products for more details.

Stage 3 - Far-Infrared Balls

The third stage, indicated in red in the diagram, consists of far-infrared emitting volcanic media that induces reduced or negative ions into the water. This results in a lower surface tension in the water allowing for better hydration. Changing the surface tension in the water also makes the water feel softer on your hair and skin, leaving you with a feeling of having just left a spa.

Like all systems, as more and more water is filtered through your shower filter it will require minimal maintenance. Some shower filters have individual cartridges that require replacing. With shower filters like the Pelican Premium Shower Filter, users replace the self-contained filter system approximately once every 9 months.


What Are the Benefits of a Shower Filter?

Shower filters reduces several contaminants, and treat the water in numerous ways.

Filters Remove chlorine

Most homeowners invest in a shower filter because of its ability to reduce chlorine from shower water.

If you’re a swimmer or have simply gone to a water park, you’re probably familiar with the drying effect that chlorine has on your skin. Without knowing it, the vast majority of Americans expose themselves to some levels of chlorine on a daily basis, when they take a shower.

Besides irritating the skin and drying out the hair, chlorine also poses potential health risks, which have raised concern among medical professionals. Like other disinfectants, chlorine reacts with naturally-occurring materials within water to form haloacetic acids and trihalomethanes, which have been linked to liver, kidney, central nervous system problems and an increased risk of cancer. Because chlorine has a much lower boiling point than water, it can vaporize in the shower and enter a person’s lungs. This is a noteworthy problem, since this type of absorption allows the chemical to bypass the body’s filtration organs.

By eliminating the chlorine in your shower water by 96%, the Pelican Premium Shower Filter:

Softens your hair

Moisturizes your skin

Reduces redness and flakiness

Reduces risk of nervous system damage and cancer

Filters Remove Chloramine

Chlorine is not the only chemical that shower filters effectively reduce: chloramines are filtered out as well. Chloramine is essentially a synthetic combination of chlorine and ammonia. Appropriately, chloramines give off a distinct and unpleasant odor that can greatly affect the overall smell of your shower water in large amounts.

Water that is treated with monochloramine can potentially have high concentrations of chemical byproducts. It’s better to shower in water that can not cause any long term health problems. Thankfully, the Pelican Premium Shower Filter greatly reduces the amount of chloramines in your shower water, keeping you safe and ensuring that your showers are odor-free.

By eliminating the chloramine in your shower water, the Pelican Premium Shower Filter:

Eliminates unpleasant odors from your water

Reduces your exposure to synthetic chemicals

Transforms your shower into a spa experiences

Filters Remove THMs

As illustrated with chloramines, there are many byproducts of chlorine treatment that can prove just as (or more) dangerous than chlorine itself. THMs, or trihalomethanes, are associated with many health risks. At elevated levels they are linked to an increased risk of cancer and adverse reproductive outcomes like birth defects.

According to the Environ Health Prespect, “a study by government and academic researchers adds to previous evidence that dermal absorption and inhalation of THMs associated with everyday tap water use can result in significantly higher blood THM concentrations than simply drinking the water does.” Thus, THMs absorbed in the shower are even more dangerous than those in your tap water.

Luckily, shower filters remove many chlorine byproducts, including THMs. Choose a shower filter that protects your family from harmful byproducts.

By eliminating the THMs in your shower water, the Pelican Premium Shower Filter:

Protects your children from unwanted birth defects

Limits your risk of developing certain types of cancer

A high-quality water filtration system is the best and maybe the only solution to protect your family from harmful water contaminants. A professional water purification system will remove chemicals to ensure the water delivered to your home is free of contaminants.

By installing a water purifying filtration system, you will limit your exposure to harmful chemicals, save money, protect the environment and provide healthier drinking water for your family.

What is a Whole House Water Filter?

A water purification system utilizes a process that is meant to remove unwanted contaminants from water. The purification process has a variety of standard requirements to meet that allow water to be used for drinking. A whole house filter connects to the main water line entering your house so that all of the water dispensers in your house dispense treated water.

Types of Common Contaminants

Sediments. Visible particles in the watersuch as dirt, dust, rust and sand. Water supplies with high amounts of sediment should consider multiple stages of sediment filtration, with the stages gradually becoming finer.

Chemicals. Most chemical contaminants can be removed using carbon filtration. The most common chemical disinfectant is chlorine, which can be removed with a carbon filter.

Iron. There are 2 types of iron found in water supplies, ferrous and ferric. Water iron and rust particles can be removed with a sediment filter, whereas clear water iron can be removed via oxidation or ion exchange.

 

The water in our homes is an important resource that we often take for granted. We bathe in the water our home provides, clean our vegetables with it, cook with it and drink it. Something that provides so much to us should be the cleanest and healthiest it can be.
