Water is associated with the fundamentals of human living. From cleaning, bathing, and cooking to drinking, it serves as an important element in our lifeline. The problem lies in the type of water you use, which many people are unaware of. Depending on where you live, your water may consist of many toxic pollutants, such as sediment, pesticides, bacteria, and human or animal drugs.

Why is the Whole House Water Filter System a Necessity?

Water pollutants are not only present in lakes, seas, and rivers, but can also be found in tap water – the primary water source for millions of people worldwide. Experts do not consider contaminants in water an actual crisis since many of them are harmless. Some are even beneficial to human health, like minerals.

When And Why Should You Worry Then?

When the level of harmful elements is excessively high is when you may begin to worry. Impure water may cause waterborne diseases or health issues. Your plumbing systems might suffer from moderate to severe damage. Stains are visible, plus you may experience persistent skin discomfort.

According to the Environmental Protection Agency (EPA) US, there are four types of drinking water contamination. Physical contamination refers to organic materials or residues, while chemicals can be synthetic or naturally occurring, such as salts and bleach. There’s also biological and radiological, with parasites, bacteria, and uranium as common pollutants.

Chlorinated Water Is Not As Safe As You Think

Even though you are using municipal water, chances are you are still getting doubtful water. It is specifically true if you have obsolete pipes. That’s why homeowners switch to chlorinated water.

This type of water can undeniably sterilize most bacteria and other microbes. However, according to several studies, consuming large amounts of chlorinated water could pose a health risk. It can negatively affect your skin and hair as well.

These issues are when the whole house water filtration system proves to be a valuable asset of any home. It uses a particular filtration system to decontaminate water at a fast rate. There is no wastewater, which makes it a much more reasonable alternative to other filtering systems. It also helps reduce the amount of chlorine in your water.

Do You Need a Whole House Water Filter?

Installing a whole house water filter is ultimately up to you, however, it is definitely a beneficial addition to your home essentials. Not all tap and well water is safe, most contain impurities, especially if you live near industrial buildings or agricultural fertilizers and pesticides.

You can test your water supply using a home water test kit to determine if you need a filter system. If it specifies:

  • You have chlorinated water.
  • Your water has a strange smell or taste.
  • Your water has a cloudy-like appearance.
  • Your water has small flecks floating through.
  • Your water contains a high impurity level.

Then, a water filter system is definitely something to consider.

Bad odors are often associated with hydrogen sulfide naturally subsisting in groundwater. A higher presence of hydrogen sulfide promotes minor symptoms (e.g., headache) to more severe symptoms (e.g., lung irritation). On the other hand, parasites and bacteria cause more critical health conditions, from vomiting and chills to malaise.

Now, let’s enter the imperative use of the water filter system. It effectively removes all forms of contaminants – providing you with more pure water all year long. It will also improve the wellness of your hair and skin with the higher quality water your showers will provide. The water test kits are available to purchase at local hardware stores. If inaccessible, send a sample and have it tested by an independent lab.

Is Drinking Filtered Water Safe?

Most whole house water filters tackle the smell, freshness, and taste of water making it perfectly fine to drink. Though, you may want to choose a water filter that is thoroughly tested and authorized to filtrate mercury, lead, and other heavy metals. Companies usually indicate in their product description if the system is 100% certified by a laboratory.

Buyer’s Guide: What to Look for in a Water Filter?

Picking which water filter to buy requires external research and proper consideration. Not all whole based water filter systems work in the same way. Each product differs in pricing and water filter performance which are essential factors to keep in mind.


For what reason are you planning to use the water filter? Some are built to filtrate deposits. Others are designed to get rid of heavy metals, chlorine, and iron. You can also find water filters with specific devices integrated, like water softeners, to cleanse water entirely.

You don’t need to have the fanciest filter in the market which is why you need to test your water source first to prevent opulent mistakes. If your water is safe to drink and use but want to make sure it won’t emit a horrible smell, then a simple cartridge will solve the issue.


How much water does your family consume every day? A household that uses a lot of water might consider getting a quality filter to ensure longer-lasting use. Never settle for a cheap alternative because it will only cost you more money in the end.

Those with smaller families can manage a smaller or averaged-sized filter. Getting a unit that won’t be of good use in the long run may not be a practical idea. This will cause you to spend excess amounts of money. Keep in mind that the best way to make your spendings worth it, balance your water consumption and the water filter durability.

Water Flow

The right water flow will also depend on your household consumption. The flow rate is measured in gallons per minute (gpm). It refers to the total amount of water running through household dispensers, such as toilets and showers.

Let’s say your household uses up large quantities of water. The unit you’re planning to purchase should be capable of providing better water flow. Smaller homes can opt for a water filter that produces ten gallons of water per minute. The average flow rate requirement can be anywhere between 15 and 40 gpm.

It is crucial to have an estimate of your water flow rate before buying a water filter. Inaccurate measurement could lead to uninterrupted water and related issues.

Filter Size & Lifespan

The perfect filter size for most homes is 4.5 inches by 20 inches. A larger filter is preferable as it equates to a longer service cycle and better water flow. As for filter life, choose one that guarantees good longevity and price value. You can have a 100,000, 150,000, or 1,000,000-gallon filter for the same machine.

Filter Cartridges

Cartridges are responsible for reducing contaminants to improve the longevity and function of the machine. Higher levels of impurities require cartridges with more innovative media to perform exceptionally.

NSF Certification

National Sanitation Foundation (NSF) is a quality standard when it comes to water filters. It is constituted by the American National Standards Institute (ANSI).

NSF conducts rigorous testing before issuing a seal of approval, regardless of the filter size. Being NSF-certified gives you complete assurance that a water filter system is of premium quality and boasts high-speed filtration.

NSF comes in various forms. For instance, if a water filter has NSF 42 certification, it can remove odor and taste contaminations. There’s also NSF 44 & 53, which eliminates heavy minerals to soften water and minimize the level of impurity.

The Water Quality Association is another quality requirement you should look for in a product. It comprises respected people based in America that tests different water filters. The machine must have a WQA seal on it for extra peace of mind.

The problem with these certifications is that they are costly to obtain. So, avoid getting too obsessed with finding approval seals from companies. Some products lack accreditations, though they are engineered with quality in mind. You’ll mostly find them from small enterprises.


Manufacturers usually include kits or accessories along with the water filter system, mostly for installing the unit. They assist with your savings while reducing the hassle of going to a hardware store.

Your budget is also a determining factor. Simple units may only cost as low as $50 and can be installed on your own, while complex machines cost hundreds of dollars and require professional installation. There are added expenses, too, including maintenance and replacement parts.

Which Type of House Water Filter Should You Get?

Another factor to take into account is the type of filter to use. Let’s walk you through various options.

a)   Carbon Water

If you often deal with organic substances, chlorine, residues, or heavy minerals that cause your water to be polluted, carbon water could help. It is one of the most common alternatives in the market, especially for average-sized homes. It is less expensive and only requires low maintenance.

b)  Reverse Osmosis

Reverse Osmosis (RO) technology handles high ratios of noxious wastes, ranging from salt and copper to fluoride and arsenic. It can potentially remove hazardous waterborne bacteria, which makes it a good value for the money.

The impurities are entirely strained, and thus, an excellent filter for cleaning and residential use. Using it as drinking water, however, is not generally recommended since the system involves stripping minerals. You can use it if you have private well water.

c)   Aeration Filter

It is another environmentally-friendly water filter option specifically designed for well waters. The process involves neutralizing toxins that affect your water’s smell and taste. Radon and carbon dioxide are among the examples.

It also discards several industrial diluters that affect the quality of water, besides iron and manganese. The pH water level is increased to make it less acidic and non-violent to use.

d)  Ion Exchange

As its name points out, ion exchange gets rid of disagreeable dissolved ions contained in water. They will be replaced with other ions with similar electrical charges to make the water pollutant-free.

This filtration method is low-cost, regenerable, and effective at disposing of negatively and positively charged contaminants such as fluoride, sulfate, calcium, and magnesium. Although, it could be weaker in removing microorganisms and organic impurities.

e)   Ultraviolet Disinfection

The central function of Ultraviolet Disinfection (UV) is to eliminate viruses and bacteria. It is eco-friendly since it relies on UV light frequencies to sanitize water. Some companies combine it with other whole house water filter systems to remove common impurities, including pesticides and chlorine.

The UV filter kills up to 99.9% of harmful microbes in the tap or well water, plus the maintenance is relatively easy. It will also save you hundreds of dollars from energy bills.

Whole House Water Filter Systems Installation & Maintenance

The level of difficulty for installing a whole house water filter system depends on its dimension or bulkiness. The bigger the unit is, the more elaborate the details. You don’t necessarily need to have plumbing expertise, though it is an advantage on your side.

Manufacturers provide a step-by-step guide through videos or manual instructions. Just follow the steps thoroughly, and you’re on your way to having fresher water. But to give you a basic idea here’s how to install a water filter system in your home.

Step 1: Drain The Water.

First, go to the main water source and shut it off. Be sure there are no small traces of water from the system. Drain it off completely.

Step 2: Cut The Pipe

Decide where you want to locate the filter. Mark the preferred location. As possible, it must be easily accessible since you will need to change the filter often. Now using a pipe cutter, create two cuts.

Step 3: Assemble & Connect The Fittings

Different water filter systems require different methods for installing brass or plastic fittings and compression nuts. Check your manual for a detailed guide. A Teflon tape is recommended for sealing filter port and fittings.

Step 4: Place The Water Filter

When positioning the water filter, ensure both the in and out ports are not installed backward. The proper placement of the port is on the water meter’s end closer, while the out port must be pointing at the water heater.

Step 5: Switch On The Water

Finally, after inclusive planning, you are now ready to try your newly installed whole house water system. Switch off the inlet valve of the filter t0 check for leaks. If there’s none, continue switching on the inlet valve to double-check.

Maintenance Tip:

Change the water filter as necessary – it varies between models. Usually, you will have to shut off the inlet valve and screw off the filter using a wrench. While you are here, clean the inside with a dry cloth. You do not need a laborious method for cleaning the filter, which homeowners with an active schedule will definitely favor.

Now, insert the new filter. Again using your wrench, tighten it up. Switch on the inlet valve and let the water run for a minimum of ten minutes before using the water.


Health comes first above anything, and your water plays an essential role in this. The whole house water filter system may seem like a very posh investment starting from product acquisition to installation and maintenance. However, you are actually saving hundreds of dollars. It is a lifetime investment worth noting.

If you live anywhere that doesn’t have pure natural water, consider what this convenient unit can do. The filter system ensures you get cleaner, healthier water at all times by eliminating up to 99.99% of impurities.

It also guarantees that harmful microorganisms will not get into your water supply. Installing any of these water filter systems can help you save money and, most importantly, preserve our environment.
