🧾 Whole House Water Filter Buyer’s Guide
Looking for the most up-to-date information about whole house water filters?.
I’ve put together the guide below to help you learn everything you need to know to choose the best whole home water filter for your specific needs.
💡 What are the Types of Whole House Water Filters?
There are several types of whole house water filtration systems available today:
Single Tank Systems
Single tank whole home water filters consist of a single tank containing a filtration media.
Typically you will see carbon, KDF, or a combination of media types used in these systems, targeting a range of contaminants such as chlorine, chloramine, PFAS, pesticides, and THMs.
Most single tank systems come with a sediment pre-filter to protect the media. Depending on the system you buy, the media should last between 6 months and 6 years before it needs replacing.
Because of their stainless steel tank designs, the majority of single tank whole home filters can be installed outside as well as inside.
Cartridge filters consist of a series of filter cartridges and are designed to remove a broad range of contaminants from drinking water.
Most cartridge filter systems will include a granular activated carbon filter that can remove chlorine, heavy metals, pesticides, herbicides, and more. A cartridge whole house water filter system typically also features a carbon block filter and a sediment filter.
Using multiple types of cartridge filters allows this type of whole house water filter to target a bigger range of contaminants than a single carbon filter.
Whole Home Reverse Osmosis Systems
Another popular option for whole home water filtering is a reverse osmosis water filter system, a filter that can remove 99. 9% (or more) TDS from both well water and city water, including heavy metals, bacteria, and chemicals. You might need a whole house RO water filter system if you’re looking for more thorough contaminant removal.
RO filters are more expensive than other whole house water filter alternatives, and can be costlier to maintain, but they’re the most efficient at removing the broadest range of contaminants from water. While standard carbon filters are priced in the hundreds, RO types of filters for the home can cost up to $3,000 to $6,000 depending on the complexity of the model.
Traditional reverse osmosis systems waste around 4 gallons of water for every 1 gallon of filtered water produced during the RO process, although newer models are more efficient, wasting only 1-2 gallons of water per 1 gallon of purified water produced. RO also removes healthy minerals from a water supply.
Ultraviolet Disinfection (UV)
UV filters use ultraviolet light to damage the DNA of waterborne pathogens, like bacteria, viruses and protozoa. These filters can be used as standalone water treatment solutions, or combined with cartridge or tank filters to remove a broader range of contaminants.
A UV filter can only remove live pathogens from water. This type of whole house water filter system can disinfect water by destroying harmful microorganisms, but won’t improve water taste or quality.
Some whole home filtration systems offer UV filtration as an optional add-on, which is worth considering if you have well water or you have any reason to be concerned about microbiological contamination.
🤔 Do I Need a Whole House Filter System?
It’s your choice whether you decide to install a whole house water filter system. However, most tap water supplies contain traces of harmful impurities, and the best way to stay protected is to filter your water at home.
You can test your water to determine whether a whole home water filter is needed in your home. If your test specifies one of the following things (or if you notice these things yourself), a whole house water filter can improve your water quality and make it safe to drink:
- Your water contains a high level of impurities
- Your water is chlorinated
- Your water is cloudy or has small particles floating in it
- Your water tastes or smells strange
The main purpose of a whole home water filter is to remove a broad range of contaminants from drinking water, giving it a nicer taste and making it safer to drink. If you want to improve your water quality, using a whole house water filter system is the best way forward.
📌 How to Choose the Right Filter for Your Home
1) Understand Your Water Quality
Before you can buy a whole house water filter system, the first step is to understand what you actually have in your water.
If you get your water from a municipal supply, you’re probably dealing with chlorine and other chemicals, as well as some heavy metals, including lead. Well water, on the other hand, contains a completely different set of harmful contaminants: iron, sulfur, manganese, tannins, and even bacteria.
Finding out what your water contains will help you choose a system that will remove these impurities.
2) Select System Type
Once you know what’s in your drinking water, you can look at your system options. The types of whole-house water filtration systems are listed earlier in this buyer’s guide.
Make sure you’re aware of all the available systems, and their pros and cons. This will help you to weigh up your choices when you come to deciding on the right system for you.
3) Determine the Right System Size
Not all whole-home filters might be sized to fit your home. Some filters come in multiple sizes to cater to different-sized households with higher or lower water consumption and flow rates.
It’s important to size a whole house water filter system correctly to ensure the system can provide water quickly enough to meet demand and avoid possible issues such as leaking.
In many cases, the manufacturer will tell you exactly what sized home their water filtration system is suitable for (e.g. 1-3 bathrooms). Otherwise, you should find information on how many gallons of water a filter system can produce per minute, or per day. Here, you’ll just need to work out your daily water use – or use the average water use of 80-100 gallons per day per person – and find a filtration system that can handle at least this amount.
4) Identify a System That Fits Your Needs
Finally, you should use the data from points 1, 2, and 3 to find a water filtration system that meets your requirements for contaminant removal, flow rate, and filter capacity. You may still have several water filter types to choose from, and here’s where budget and personal preference will come into play.
Set yourself a price that you’d prefer to stick to and take a look at your available options. When you find a filter system you like, do your research and read up on customer reviews. If the product has a good reputation, you can consider making a purchase.
❗️ Key Considerations When Reviewing Whole Home Filtration Systems
A whole home water filter is a big investment, and it’s important not to rush the purchasing process. Be sure to do plenty of research before you make a final decision, and read through buyer’s guides like this one.
Here’s what to consider when choosing between whole home water filters:
Whether or not you get your water supply from a municipal or well source will determine which contaminants you’re dealing with, and what type of water filter system is for you.
Most whole house filters are designed for municipal water supplies, and can remove common city water contaminants, including chlorine, pesticides and lead. Test your water supply in advance to find out which contaminants you need a filter to remove.
If you get your water from a private well, a well water filtration system is a better choice for you.
Water Consumption & Filter Capacity
A filter’s capacity is the number of gallons of filtered water it can produce during its lifespan. The higher the water filter capacity, the more efficient a filtration system is, and the quicker you’ll be able to benefit from filtered drinking water from a private well or a city water supply.
Standard whole home water filters, like carbon-based filters, don’t produce any water waste and have better filter capacities. This method of water filtration doesn’t flush away water during the process. A filter’s capacity depends on its quality and the materials that make up the filter.
The longevity of a filter usually depends on the manufacturer and the quality of the product. Different water filter types may last longer than others.
Generally, pre-sediment water filters have the shortest lifespans, as they can become quickly clogged with large particles. Most pre-sediment filters need changing after about 3 to 6 months.
Carbon filters and remineralization filters (for adding healthy minerals to water) have an average lifespan of 6 months to 1 year, depending on filter use.
RO membranes can last for up to 2 years before they need changing.
Read up on a product to learn when the filters require changing. Some of the best whole house water filter systems contain more filters than others. No filter lasts forever, so no matter what model you go for, you’ll have to regularly replace your filters if you want to get the most out of your system.
Contaminant Reduction Capability
Not all whole house filters remove the same contaminants. While most will target chlorine and lead, some are capable of removing hundreds of contaminants, while others can remove less than 10.
You need to know what’s in your water supply before choosing a water filter based on its contaminant reduction capabilities. I suggest that you request a water quality report from your local area’s tap water provider. This can give you a breakdown of the different elements in your drinking water. Another way to find out the quality of your water is to test yourself using a water test kit.
Once you know what’s in your tap water, you can determine what you want to remove.
System Footprint & Space Available
Your household water system will need to be installed somewhere, which means having free space for connecting a whole house water filter to your main water line.
Not only will you need enough space to store your water filter, you’ll also want easy access to the unit whenever you have to change a filter or perform system maintenance.
Sediment Pre-Filter Micron Rating
A micron is a unit of measurement, with 1 micron being equal to a millionth of a meter in length. Microns are tiny – we can’t actually see anything smaller than 40 microns.
A filter’s micron rating is its ability to remove contaminants based on their micron size. So, for example, a 5 micron sediment filter will be able to remove particles as small as 5 microns, or a 1 micron filter filters up to 1 micron in size.
Nominal micron rating gives a measurement of a filter’s ability to remove specific particle sizes at an efficiency of 50% to 90%. So, if a filter has a nominal micron rating of 5, it can remove particles as small as 5 microns at a 50% to 90% efficiency.
Absolute micron rating provides information of a filter’s ability to remove specific particle sizes at an efficiency of at least 98.7%. This means that if a filter has an absolute micron rating of 5, it’s much more efficient in removing a particle as small as 5 microns – it will remove a minimum of 98.7% of the particles from water.
You should be able to find the micron ratings of a particular filter in its product information. As all particles are variously sized, a micron filter rating will give an indication of the types of particles it will remove best.
Household water filtration systems that consist of a larger variety of filters tend to be the best high quality water filter option for removing the largest quantity of contaminants from city and well water, because their filters are designed to remove particles at different micron sizes.
There’s a substantial difference in price between carbon filters, and reverse osmosis or next generation technology filters.
Standard whole house water filtration carbon-based filters are generally cost-effective, costing $300 to $600 in price. Some whole house filters are more expensive, and you may need to pay more for features like remineralization filters or a UV filtration option for water purification.
RO and next generation filters cost between $1,000 and $3,000 to purchase. Whole house RO filters can reach the highest in price, with some peaking past the $5,000 mark. A RO system is a much bigger investment than a carbon-based filter, and if your budget is more flexible, you’ll need to decide whether it’s worth paying more for the additional benefits of RO. You can also use a UV filtration device with a RO system.
Check out this post to learn about all the costs involved with operating a whole home system.
Water Flow & Pressure
Your household’s water flow and water pressure is a factor that will affect the efficiency of even the best home water filtration system, especially RO systems.
You might think that a higher water pressure or water flow is always the best way to filter water, but that isn’t true. Carbon whole home water filter systems benefit from a slower water flow, as it allows the filters to thoroughly remove particles from water.
With RO filters, on the other hand, a water pressure of 60 PSI is optimal for water filtration. This type of filtration requires adequate water pressure to force water through the RO membrane at a sufficient rate, making it less environmentally friendly than other processes.
You can test your home’s water pressure with a pressure gauge that measures in PSI.
The best whole home water filtration systems are certified by either the WQA or NSF/ANSI. Certification proves that a filter works to the standards as advertised by its manufacturer, whether you plan to use it for city (municipal) water or well water.
Common NSF certifications for these systems are:
- NSF/ANSI 42: for the removal of chlorine, taste & odor
- NSF/ANSI 53: for lead reduction
- NSF/ANSI 55: for killing microbiological contaminants with UV light
- NSF/ANSI 58: for reverse osmosis systems that remove EPA-regulated contaminants
- NSF/ANSI 401: for the reduction and removal of emerging contaminants, like pharmaceuticals or PFOAs
If a system is NSF certified, it means you can trust it to live up to its performance claims, which is good to know from a buyer’s perspective.
No matter what type of whole home filter you opt for, a good warranty is essential.
If a system has a warranty of 5 years, it tells you that the manufacturer expects to last for at least this long – and they’re happy to offer replacement parts if something goes wrong. This is reassuring to customers, as it means you’re covered if your filter has damage or defects that weren’t caused by you.
Lifetime warranties tend to be the best warranties on offer for whole home water filtration systems. This means that you’re covered throughout the entire lifespan of the system – although, of course, this could range from 1 year to 10+ years, depending on the model. Always read a warranty’s terms carefully before making a purchase.
❔ Frequently Asked Questions
Which whole house water filter is the right one for me?
It’s worth weighing up the advantages and disadvantages of the different kinds of whole house water filters when deciding which is for you.
Keep your budget in mind – and work out what you’d save if you stopped buying bottled water and bought a whole house filter. Decide what you want to get out of a cost-effective whole house water filter. This should make it easier to narrow down your search to a particular filter type.
Why should I choose a whole house water filter over a kitchen sink filter?
Your choice is entirely based on personal preference. A whole house water filter will give you all the benefits of a kitchen sink filter, as well as a couple of extras.
Because whole house water filters filter out chemicals at the water’s POE, where water enters your home, you won’t be exposed to dangerous chlorine vapors while you’re showering. Some whole home water filter systems can remove iron, preventing rust from forming in your home’s appliances.
These benefits are all great, but if you’re just looking for clean drinking water from your well or municipal source, opting for one of the best whole house water filters isn’t essential.
How much should I expect to pay?
Whole house water systems can cost anything from $500 to $3,000. You should only pay more than this for a filter if the product offers unique features or benefits that you won’t find elsewhere.
What’s the difference between a water filter and a water softener?
The filtration process is different from the water softening process, and each system has its own unique intended outcome.
A water softener doesn’t actually filter contaminants. Instead, a traditional water softener uses ion exchange to eliminate water hardness, while a water conditioner alters the formation of hardness minerals and prevents scale formation. While a water filter can be used to remove a variety of contaminants, a water softener only focuses on water hardness.
💭 Final Thoughts
A whole house water filter is a water filtration option that’s best for well water or a municipal water source. It provides all of the benefits of a kitchen sink filter, with the added bonus of supplying your entire home and its appliances with safe, chemical-free, clean water.
