Best Whole-house Water Filtration System 2023

Every house needs to have access to a source of water that is free of bacteria and other contaminants. However, the supply you have could contain a variety of contaminants, depending on where it came from. These impurities could include heavy metals, sediment, bacteria, viruses, and significant quantities of compounds such as chlorine and hydrogen sulfide. If your water has an unpleasant flavor, an odd odor, an unusual color, visible particles, appears suspiciously cloudy, or stains your clothing or utensils, a whole-house water filtration may be able to fix the issue. Other symptoms of water quality issues include these: Several different types of filtration, including small physical obstacles, KDF (kinetic degradation fluxion), carbon, and UV light, are utilized by water filtration devices. After having one installed, the water supply in your house will be treated in a single location to eliminate the contaminants in question before it travels through all of the pipes and is delivered to each and every faucet.

A number of factors should be taken into account before purchasing a whole-house water filter, including the flow rate, which indicates how quickly the water will pass through the system and to your desired location, the frequency with which the filter must be replaced, and whether or not the entire unit must be dismantled in order to be serviced. A new, not-so-budget-friendly refrigerator can cost upwards of $2,000 or more, but a long-lasting whole-house water purifier will cost the same, says Richard Epstein, a qualified master plumber and member of The Spruce Home Improvement Review Board. One more thing to think about is that the price of such a filter won’t be much different from any other. You should get advice from an expert who can help you sort through your options and decide which one is best for you.

You will want to make sure that the filtration system is intended to remove the particular contaminants that are present in the water that comes from your tap. Epstein says, “It’s best to have the water tested by a certified lab or consultant, as well as a comprehensive review of appliances and fixtures, in order to determine what will work best. This applies whether you are unsure as to what is contaminating your supply or you are simply looking into the whole-house water filters that are available to you.” If you are unsure as to what is contaminating your supply, or if you are simply looking into the whole-house water filters that are available to you, This will help determine whether you need filtering throughout the entire building or just at the place of use. He goes on to say that “drinking grade water at every location” is not a requirement for whole-house filtration systems because the cost of doing so can build up quickly.

You can determine the quality of your water by taking a sample to a laboratory that has been approved by the state. It is in your best interest to get in touch with either the laboratory or the local health department in order to confirm that you are collecting the samples correctly and do not require assistance. After you have received the findings of the test, you and a trained professional can collaborate to determine which whole-house water filter will serve your requirements most effectively, and the trained professional can also assist you in installing the filter.

What We Like

  • Deodorizes water supply
  • Simple maintenance requirements
  • One-year warranty

What We Don’t Like

  • Doesn’t filter bacteria or viruses
  • Can be very leaky

What’s contaminating your supply is eventually the most important factor in determining which is the best filtration for your house. However, the Express Water WH300SCKS 3-Stage Filtration System effectively deals with a wide variety of pollutants, including lead and organic matter, making it a great option for a wide range of homes. When you use this method, the first step that your water will take is to go through a sediment filter, which removes large particles as well as organic and inorganic debris. After that, the KDF filter gets rid of small amounts of heavy metals such as lead, iron, mercury, and copper. Last but not least, the activated carbon filter is used to deodorize your supply in order to enhance both its flavor and its scent. Additionally, the carbon lowers the amounts of chlorine and takes care of turbidity, which is the degree to which your water is cloudy.

The only things that aren’t removed by this purification system for the entire house are germs and viruses. Because some of the components that connect to your infrastructure are made of plastic, which is not as resilient as metal, it also has the potential to be quite leaky. Nevertheless, aside from that, the construction of this system is very solid and made of stainless steel, so it should last for many years to come. It is recommended to change the filter for each of the three phases approximately every six months; however, this can be done quickly and easily without disassembling the system.

What to Look for in a Whole-House Water Filter

Contaminants Filtered

According to Richard Epstein, a qualified master plumber and member of The Spruce Home Improvement Review Board, it is best to have your water tested before buying a whole-house water filter because filtering systems vary in terms of what pollutants they eliminate. Chlorine and hydrogen sulfide are two of the most prevalent types of contaminants, and both of these can have an impact on how something tastes and smells.

There are also substances that can pose a threat to one’s health. Some examples of these include bacteria, fungus, viruses, and other waterborne organisms. Heavy metals such as lead, iron, mercury, and copper are also examples of such substances. Lastly, the majority of water purification systems, but not all of them, are designed to remove particulate matter, such as sediment, grit, soil, and rust.

Flow Rate

The amount of water that can be filtered through a device in one minute is quantified in gallons. (GPM). In general, lesser flow rates are preferable because they enable more interaction time with the screening media, which results in the elimination of a greater number of contaminants.

The number of people living in your home is another factor that should be considered when calculating the optimal discharge rate for purifying your water supply. For instance, a maximum of 7 GPM is recommended for a single-family home with two persons using the bathroom. This is because two people require more water per minute than one person does. However, residences that contain five persons or more and three bathrooms or more will likely require a higher flow rate of approximately 15 GPM.

Required Maintenance

The majority of whole-house water filtration systems are fairly simple to maintain after the original implementation has been completed. The routine replacement of water filters is the single most essential action that must be done. Be careful to consult the manual, as the frequency of replacement for some can be as high as once every three months, while others can remain functional for an entire calendar year.

Due to the fact that each model is one-of-a-kind, it is recommended that you search for an alternative that does not require disassembly each time the filters are changed. In addition, just like the rest of your heating, ventilation, and air conditioning (HVAC) equipment, it is recommended that you have a qualified technician perform maintenance on your water filtration at least once per year.


Are whole-house water filters worth it?

Epstein notes that the price of a decent whole-house water purifier can range anywhere from $2,000 to more than $3,000, depending on the level of filtration that is desired. While the price of many models is around $500, The purchase of a water purifier is an excellent expenditure for many different kinds of households.

Epstein recommends taking stock of your present requirements in order to ascertain whether or not the investment will be beneficial. Are you imbibing or consuming a significant amount of water from the tap? Is there a tinge of color in the water? Does it have a scent to it? Is there a large concentration of particles?” The answers to these questions can shed light on the level of urgency and necessity associated with installing a purification system in your house.

Do whole-house water filters remove lead?

The removal of lead and other heavy elements, including mercury, iron, copper, manganese, chromium, and arsenic, is a function of some whole-house water purifiers. However, not all systems are intended to remove lead, even if they can filter other heavy metals; therefore, before purchasing a system, it is important to make sure that you read the product description carefully.

Epstein suggests investing in a reverse osmosis system that complies with the standards set forth by the National Sanitation Foundation (NSF) if there is lead present in the water source at your location. Lead can also be effectively removed from drinking water by using whole-house water purifiers that contain kinetic degradation fluxion (KDF) media.

Where are whole-house water filters installed?

Epstein explains that these filters are typically installed at the point where the water supply enters the home in order to purify all of the water used for household purposes. It is highly probable that the primary water shut-off valve for your home is located on the exterior of the structure, possibly in the basement, garage, or utility area, but it could also be in the basement. In addition, according to Epstein, electricity is generally necessary, and “drainage may be necessary for automatic washdown of the filter.”

How long do whole-house water filters last?

The tanks of the majority of whole-house water purification systems have a lifespan that can range anywhere from three to ten years, depending on the capacity of the system and the size of the residence. There are some high-end ones that can last for up to twenty years.

However, the filters do not have a particularly lengthy lifespan and will eventually need to be replaced. Filters that remove sediment and charcoal typically need to be replaced every three to six months, whereas UV water filters typically last for about a year before needing to be replaced. KDF media has a much extended shelf life, typically ranging from three to six years.
