In a perfect world, the water that flows from your tap should be clean and safe enough to drink. It shouldn’t damage your pipes, dishwasher, and washing machine with limescale build-up. It should leave your hair feeling soft and silky after a bath, and it shouldn’t leave behind water stains on your shower glass or limescale in your toilet bowl.

But it’s not a perfect world, and short of selling your home, you’re stuck in that place and you have to make the best out of the water provided by your city or the well water you’re using.

The good news is you don’t have to play a game of chance with your health every time you drink a glass of water when you have a whole house water filtration system. 

In this article, we’re going to discuss why whole house water filters are essential for every home, as well as what you should look for when choosing the perfect product.

We’ve also curated and reviewed the best whole house water filters to get you started.

Amebiasis, typhoid fever, cholera, giardia, and norovirus infection.  

These are just some of the diseases you and your family can get if you are still drinking unsafe water. Every year, millions of people around the world die because of water-borne diseases, especially in developing countries.  

But impure water does not just negatively impact your health. In industrialized countries, water abundant in calcium and magnesium causes the build-up of scale in pipes, as well as in appliances that use water, such as dishwashers, coffee makers, and washing machines. Excessive amounts of certain harmful compounds in water can also cause fluorosis, arsenic poisoning, and lead poisoning.

The invention of water filters has greatly helped in reducing the number of fatalities who have contracted water-borne diseases and water-related poisoning. Plus, water filters have also extended the lifespan of pipes, dishwashers, and washing machines.

There are a lot of water filters available for ordinary homeowners today, but one particular product we’re going to focus on is the whole house water filtration system. Unlike faucet-mounted or on-counter filters, whole house water filters are not just connected to the faucet where you get your drinking water. 

This type of water filter is used to treat every drop of water that enters your home. The majority of whole house water filters can absorb sand, dirt, and other sediments. Some can block heavy metals and volatile organic compounds from passing through your faucets. Other units are equipped with germicidal UV filters that get rid of bacteria, viruses, and other microbes.hole house water filtration systems, however, are expensive. You also have to modify your pipes or have a plumber do it for you to install the units. Some products also need professional maintenance.

A lot of whole house water filtration systems, however, are expensive. You also have to modify your pipes or have a plumber do it for you to install the units. Some products also need professional maintenance.

Another downside of using some whole house water filtration systems is the removal of chlorine which results in the slow yet steady growth of microbes in the pipes of your home.

Choosing The Best Whole House Water Filtration System

Filters

There are different types of filters, and each filter is designed to block certain types of contaminants. Some filters only absorb sediments, such as clay, silt, sand, rust, or anything that causes turbidity in water. 

Activated carbon filters can block organic contaminants and chlorination byproducts from entering your home. Some types of activated carbon filters can even absorb pesticides, herbicides, and cleaning solvents. But this type of filter cannot effectively block bacteria, lead, nitrates, and copper.

Another type of filter available for homeowners is kinetic degradation fluxion. It uses a process called oxidation-reduction or redox to block hydrogen sulfide, chlorine, iron, and mercury from entering your home’s water supply. Redox can also reduce the presence of algae, bacteria, and fungi in the water you use.

If you want to remove bacteria, viruses, and other microorganisms, then you can check out UV filters. These filters use a method called ultraviolet germicidal irradiation to destroy molds, viruses, and bacteria.

Keep in mind that not all filters are created equal. Before buying a whole house filtration system, check the filter’s capacity as this can affect its longevity. Some can filter as little as 15,000 gallons of water before they need to be replaced, while others can go as much as 1,000,000 gallons before you have to replace them. 

Flow Rate

Whole house water filters have different flow rates. Smaller water filters produce as little as 7 to 10 gallons per minute, and that’s fine if you have a small home with one or two bathrooms plus kitchen or your household has fewer members.

But if you have a large house with a kitchen and multiple bathrooms or you have multiple family members who sometimes need to use the bathroom during a certain time of day, then look for whole house water filters with higher flow rates. 

Household Water Consumption

Determine and consider your household’s water consumption when choosing the best whole house water filtration system. It can be tempting to buy a cheap water filter, but if your water consumption is through the roof, the cost of replacing the filters every month will be more expensive in the long run.

But keep in mind that some good-quality and expensive water filters clog up when they are not used frequently or if the water that passes through them for some time is insufficient.

Conclusion:

We’ve come to the end of our review. Before we end, let’s see which product is considered the best whole house water filtration system right now.

We’ve chosen not just one, but three whole house filter systems to recommend. The reason for this is because all homeowners are different, and there is no one-size-fits-all when it comes to filtration systems. 

A cheap single filter system is not ideal for a large home with three bathrooms plus a kitchen. But a complete whole house filter system with descaler and UV light is definitely not a great choice for a homeowner who is on a tight budget. So, what are the best whole house filter system that fits your needs and your household?

Let’s start with those who are looking for the most affordable whole house filter system they can find.

The best budget-friendly whole house water filter is the GE GXWH40L High Flow Whole Home Filtration System. At the time of writing, the unit only costs between $50 and $70, making it ideal for families with fewer members or houses with one or two bathrooms, plus a kitchen.

The transparent sump allows you to see when it’s up for cleaning. This also allows you to check if you need to change the filter medium or not. You can purchase the affordable filter medium from GE, but you can also buy a compatible one from other brands.

If you’re looking for a mid-range whole house water filter, then the Express Water WH300SCKS Heavy Metal Whole House Water Filter is a good candidate. This three-stage water filter gets rid of a whole lot of contaminants to keep you and your family safe, as well as prolongs the life of your pipes and appliances.

The whole unit can remove sediments, heavy metals, volatile organic chemicals, and some microbes. The health of each filter is monitored by gauges, and this filter system is encased in a metal cage that you can mount on the wall or set on the ground.

All of the filter systems we’ve tested performed well, but the king of all whole house water filters is the Aquasana OptimH2O Whole House Water Filtration System. It is quite expensive, but that’s a small price to pay for your peace of mind.

Unlike regular whole house water filters, the Aquasana OptimH2O has four stages. The first stage is for effective sediment removal, while the second stage is for removing lead, chlorine, and other harmful chemicals.

It also has a descaler that prevents harmful mineral build-up in your house’s pipes and appliances. Finally, the water passes through a UV light that gets rid of bacteria, viruses, and other microbes.

If you’re an experienced DIYer and you’re confident in your plumbing skills, then go right ahead and install it. But it’s easy to overestimate one’s DIY skills and easier to mess things up. To prevent any mishaps (this is a very expensive whole house water filter that you can’t afford to mess up), it is recommended that you hire a professional plumber to install this unit.
