4 Benefits Of Installing A Whole House Water Filtration System

Water is essential to our survival, and vitally important for our health. We stay hydrated with it, cook with it, and bathe in it. While you may be thinking that these are all obvious facts, what isn’t always so obvious is what’s lurking in the water that you use every day. Whether you have municipally supplied tap water or use private well water, your water could contain contaminants that negatively impact your health.

Even if your water is free of contaminants, mineral deposits can cause damage to your plumbing and appliances over time, and cause dry and irritated skin.

Practical Considerations Before Buying A Water Purifier For Your Home

Currently, there are multiple water purifiers available in the market. All water purifiers have their own USPs and all claim to give the best water quality. However, what you need to keep in mind is that all water purifiers come with different technical specifications and have certain basic requirements.

Knowing which one will work for you, depends on factors like water pressure, water quality, and space available and if you are unsure which one you should go for, then take a look at this guide on how to choose a water purifier to select the best water purifier for home use.

Now, before we delve deeper into which is the best water purifier for home use, let us first understand what are the most common water purification techniques.

1. Most Common Water Purification Techniques

There are different types of water purification techniques, however, here are some of the most commonly used water purification methods that have proven their suitability for home use.

  • Activated Carbon Filters

Activated Carbon filters work on the adsorption method. When water passes through a carbon filter, activated carbon adsorbs harmful molecules that are present in water. An activated carbon filter is used as a complementary filter with other water purification techniques like UV purification and RO purification.

  •  Ultraviolet Purifier

Tips for Buying Water Treatment Equipment

Surveys have found that about 60 percent of the homes in Pennsylvania served by a private water system (well, spring, or cistern) have some type of water treatment equipment. Today, almost any water quality problem (both nuisance and health based) can be fixed by purchasing the appropriate equipment. However, homeowners with private water systems are often uninformed about water treatment processes and equipment, making them susceptible to unscrupulous businesses selling treatment equipment.

Understand the Water Quality Problem

If you suspect that you have a problem with your water, make sure to have it tested by a state-certified water testing laboratory. A list of state-certified water testing laboratories is available from the Pennsylvania Department of Environmental Protection. Penn State also runs a state-certified water testing laboratory. Test kits can be obtained at your local Penn State Extension office or directly from the lab.

If test results from a certified laboratory show that your drinking water failed a primary, health-based drinking water standard, such as bacteria or lead, action should be taken to correct the problem to protect the health of you and your family. Other water tests may indicate a problem from a secondary pollutant such as iron or manganese. In this case, your health is not at risk, but you may choose to install water treatment equipment to reduce stains, tastes, or odors that these pollutants can cause.

Consult Unbiased Water Quality Experts

After receiving your test results from the certified water testing laboratory, it is a good idea to go over the results with an unbiased water quality expert. Unbiased experts may be available from the water testing laboratory or from your local Penn State Extension office. They can help you interpret the test results and provide advice on options available to fix any water quality problem.…

The 5 Different Types of Water Purification Methods

1. Boiling

Boiling is the simplest of all water purification methods. It is effective because it kills 99.9% of all living things and vaporizes most chemicals. It’s a good method to use for water contaminated by living micro-organisms.

How Boiling Works

The micro-organisms are eliminated by heating the water to its boiling point.

Because some bacteria can resist high temperatures, you need to ensure the water boils for 3-7 minutes, depending on your altitude. For people living in high altitude areas, it is recommended to boil your water for longer than water boiled at lower altitudes. This is because water boils at lower temperatures in higher altitudes.

After adequate boiling, let the water cool down. This is important to allow any solid matter in it to settle at the bottom. After cooling, the water is safe for human consumption.

Should You Go for Boiling?

One of the advantages is that no chemicals are added to your water. However, you need to be sure that your water source is not contaminated by heavy metals, nitrates, pesticides, or solvents because boiling will not remove them.

Boiling removes all oxygen from water, and the result is that it may taste flat. However, this is a minor negative as it can be solved by simply shaking the purified water in its container. Also, to improve the taste of the water, a pinch of salt may be added.

2. Chlorination

Chlorination is one of the most common water purification techniques that has been in use for many years. Likely, it is because it is easily available, cheap, and effective.  Chlorine is a heavy-duty oxidant that swiftly kills many germs, parasites, and other disease-causing organisms found in ground or tap water.

How Chlorination Works

It is important to carefully follow the instruction on …

What are the Benefits of Drinking Filtered Water?

You’re mindful about your health – you exercise, have a healthy diet, and maintain proper hygiene. You also strive to drink the right amount of water that your body needs. But have you considered the quality of the water you are drinking daily to stay hydrated? Is the water you are drinking helping you achieve your health goals or working against them? Culligan Water can help you stay healthy and hydrated by providing you with an in-home water filtering system.

Tap water contains many contaminants, and continuous consumption of such could pose serious health risks. Water filtering systems from Culligan Water will help provide solutions to these problems by filtering your water right from the tap. So, what are some of the benefits of drinking filtered water? Let’s explore more.

Contaminant Free

Filtered water is free from harmful chemicals and other water contaminants. A reverse osmosis system can help remove 99% of the contaminants found in tap water including metals such as arsenic, lead, copper, iron, cadmium and hexavalent chromium, industrial and pharmaceutical byproducts such as pesticides or hormones, chlorine and chloramine, PFOS and PFOA (Perfluorooctane Sulfonate and Perfluorooctanoic Acid), sediments and particulates.

Arsenic is a harmful carcinogenic present in unfiltered water, dangerous levels of which have been known to cause diseases. Aluminum is also often present in unfiltered or poorly filtered water. Though water softener can aid in its removal, traces can remain, and its increased consumption can cause liver diseases, hyperactivity, and skin problems.

Water filters remove these harmful substances, thus significantly reducing your chances of developing various types of cancer and other diseases related to toxic overload in the body.

Culligan Water system can ensure that your drinking water is free from these contaminants and their potential risks.

4 Methods to Purify Your Water
Purify Your Water

It’s extremely important to confirm your water has been purified or treated before drinking. If your water is contaminated and you don’t have bottled water, there are various water purification methods that are used today, and each method has its merits and demerits. Filtering is good for basic water tasks such as sediment and chlorine removal, but in the long run reverse osmosis is the best option. At Schultz Soft Water we focus on reverse osmosis units because they require a lot less energy and time required to make water versus distillation.

When reverse osmosis is not available, there are 4 water purification methods that you can use to make your water safe for drinking.

1 – Boiling

Boiling water is the cheapest and safest method of water purification. Water sources and or channels of distribution may render your water unsafe. For example, parasites and germs are things you may not see by bare eyes, but their effects can be life threatening.

In this method, clean water should be brought to boil and left at rolling-boil for 1-3 minutes. For people living in high altitude areas, it is recommended to boil your water for longer than water boiled at lower altitudes. This is because water boils at lower temperatures in higher altitudes. Boiled water should be covered and left to cool before drinking. For water drawn from wells, leave it for compounds to settle before you filter out clean water for use.

2 – Filtration

Filtration is one of the effective ways of purifying water and when using the right multimedia filters it’s effective in ridding water of the compounds. This method uses chemical and physical processes to purify water and make it safe for human consumption. Filtration eliminates both large compounds and small, dangerous contaminants that cause diseases with …

What’s The Importance of Water Filtration

We all know how essential water is. After all, humans are 60% water in their bodies, and doctors tell us that we have to drink at least 8 cups of it a day to maintain essential body functions. It is easy to pull water from our taps without considering the quality. Pollutants can ruin the taste, and cause short and long-term health effects!

Thankfully, technologies exist to help you improve your water quality. Water filtration systems are not only convenient but also cost-effective. The EPA estimates that up to 40% of Americans utilize water filtration systems in their homes. This blog will explore the benefits of water filtration and why more Americans should have them in their homes!

Why You Should Filter

There are many benefits to filtering your water at home. After exploring these benefits, maybe you will consider adding filtration to your home sinks and appliances.

1. Better Taste & Smell

Water that is filtered typically tastes better than water that is not. Heavy metals contribute to the unpleasant taste of tap water. While most tap water is “safe,” it does not mean that there are no contaminants to be found. Water filtration systems help remove these metals, improving the taste!

The same heavy metals also contribute to odd-smelling water. When your water smells bad, you are less likely to drink directly from the tap. There are also volatile organic compounds that contribute to bad smells, which can also cause damage to your body.

2. Save Money & The Environment

One reason that people purchase bottled water is to make sure that it is safe to drink. For example, when there are city-wide water contamination issues. However, with a filter at home, you can provide your source of safe drinking water. This will save money in the long …

Nowadays, to make sure that the water we use is clean, treatment facilities add chlorine to it, which can be damaging as it may contain harmful bacteria and chemicals that have a negative effect on our health and wellbeing.

Tap water passes through water treatment facilities, however, it can get easily contaminated the moment it leaves the treatment facilities. Therefore, the best way to make sure that the water you consume is clean and hasn’t been contaminated is by installing a water filtration system.

In this article, we will provide you with the major benefits of having a water filtration system in your house.

Safe to Drink

Installing a water filtration system will ensure that the water you drink is clean, free of contaminants, and safe to drink compared to those coming from water treatment plants without going through a home filtration system.

HOW DOES PURE WATER WINDOW CLEANING WORK?
Pure water window cleaning - how does it work and what are the benefits?

You’re probably wondering what pure water window cleaning actually is. After all, water is just water, right? Well, you’d be wrong there. The difference between water and pure water is that the water has been deionized and treated to remove any impurities. When cleaning your windows you don’t want to use typical tap water, as this makes it difficult to achieve that flawless finish you’re looking for. Tap water contains mineral and dissolved solid particles, so when cleaning windows it is best to use purified water.

HOW DOES IT WORK?

Pure water window cleaning is currently a popular choice for window cleaners, providing a reliable solution that doesn’t involve harsh chemicals. But how does it actually work? Well, once it’s being used on your windows you’ll find that pure water is free from any chemicals and minerals that are often put into tap water and makes it an inefficient option for window cleaning. Window cleaners will typically purify their water by using methods such as reverse osmosis and deionization – the water will then be stored in suitable containers and environments to keep it pure. The pure water will then be used to clean your windows before often being left to dry naturally, giving you that streak-free and crystal-clear finish that you’re looking for.

WHAT ARE THE BENEFITS OF PURE WATER WINDOW CLEANING?

Pure Water Window Cleaning for Professional Outdoor Window Washing

You may not know that the residue left behind by using tap water and detergents is what can attract dirt to your window, so by using pure water window cleaning you are removing this film of grime-attracting soap from your windows – which will keep your windows looking fresher for longer. Pure water is also a more eco-friendly alternative to tap water and chemicals, preventing any of those harsh chemicals from entering the garden and harming any …

Choosing Home Water Filters & Other Water Treatment Systems
What to consider before installing a water treatment solution ?

Step 3: Consider how the filter fits your home, lifestyle, and budget.

Many different types of filters are available to consumers. Determining which type is most appropriate for you—or whether you need a filter at all—depends on what functions you want a filter to provide. No filter eliminates all contaminants, so understanding what filters do and do not do is important.

What does the filter remove?

Read the label to see if it is NSF-certified.  If it is, you can search NSF’s databaseexternal icon to learn more about what a particular model is certified to protect you against. Labels on water filters also typically state the contaminants that are reduced, which can help to guide your choice. Be sure to read labels carefully yourself and verify the manufacturer’s claims with an independent source, as not all sales representatives will be familiar with your needs.

Keep in mind that most brands include many different types of filters. Sales people might be able to help you make an appropriate selection, but remember that they are sometimes paid to sell a particular brand. You should check claims and read the fine print on filter packaging for yourself and ensure that it will work for your purposes before purchasing.

Don’t assume that if the filter removes one contaminant, it also removes others. Filters that remove chemicals often do not effectively remove germs, and vice versa. Some water treatment devices that remove chemicals, such as reverse osmosis, ion exchange, or distillation systems, might also remove fluoride. Children who drink water with levels of fluoride <0.6 ppm might need a fluoride supplement. Check with your child’s pediatrician or dentist for specific recommendations.

How much does the system cost?

The prices of different filtration systems can vary widely, from simple systems that can cost …

Nutrients in water

Before looking at the individual sources of drinking water it’s important to understand what the potential nutrition contribution of drinking water is. Many people consume mineral waters because of the perception that they may be more healthful. But are they?

In 2005 WHO held a conference with experts from around the world to investigate. At the conference, information was shared from over 80 epidemiology studies of varying quality over the last 50 years. The studies addressed the issue of hard water consumption, mineral impact on health and possibly reduced incidence of ischemic cardiovascular diseases in populations.

Water supplies for tap and bottled water are highly variable in their mineral contents and, while some contribute appreciable amounts of certain minerals either due to natural conditions (e.g., Ca, Mg, Se, F, Zn), intentional additions (F), or leaching from piping (Cu), most provide lesser amounts of nutritionally – essential minerals.

With all of these considerations in mind, the nutrients sometimes found in drinking water at potentially significant levels of particular interest are:

  • Calcium–important in bone health and possibly cardiovascular health
  • Magnesium–important in bone and cardiovascular health
  • Fluoride–effective in preventing dental caries
  • Sodium–an
