Buyer’s Guide to Best Whole House Water Filter
Before looking at our top picks for a house water filter, there are several factors to think about in preparation for installing your first filter. For instance, what hardware and installation tools are needed for whole home filter DIY? There are also a few benefits to having a filter installed in your home as well. In our whole house water filter review below, you’ll see some of the picks that match what we’re looking for in terms of quality, price, and installation.
All About Best Whole House Water Filter
With a whole house filter system, clean water is delivered to all areas of your home. While that means you can enjoy pure drinking water from every faucet, it also means that you can shower and cook with filtered water as well. There are also benefits for washing your clothes in chlorine-free water.
However, the best whole-home filters also require proper installation. This means that you’ll need the right tools, pipes, and water source to have everything up and running efficiently.
Some common contaminants can be found in your home’s water system, including sediment or particles in your water. These chemicals can be removed with a carbon filter or reverse osmosis process.
These filters typically have a multiple-stage filtration process that allows you to remove 99.9% of all toxins in the water, including things like chlorine, fluoride, arsenic, mercury, petrochemicals, and lead.
Match Up Your Home to the Water Filter
You’ll need to check a few specifications before you select a filter for your home. We detail these for you here:
Filter Size: With larger filters, you’ll need more water. The port size is also important as it will affect the pressure and gallons per minute (GPM). Most homes require a filter that is 4.5” by 20”, but if your home is much larger, then you’ll likely want to get a 25 GPM flow rate with a 1 ½” ports.
Flow Rate: The flow rate of your home is measured in GPM, and this number tells you how much water is available to run your kitchen sink, dishwasher, toilet, hot water heater, shower, washer machine, and more. You can look at the demand ratings on each of your appliances to determine a total flow rate. For example, your shower may have between a 2.5 and 6 GPM. Your toilet is likely a 5 GPM. Once you add all of these up, you’ll get a water flow rate between 15 and 45 GPM, depending on how much water flow you need.
Port Size: When looking at the port size of your home, then you probably want it to be around 1” in diameter. If your home uses three-fourths piping, then you’ll need a 1” ported system that will prevent any stoppages once you install the system. A 4.5” by 20” filter is best for a 1” port size.
Filter Life: While all filters vary in capacity, you want one that will last 100,000 to 150,000 gallons. Carbon filters with carbon beds have longer capacities, but this also works better with a normal backwash cycle and backwashing valve.
Where to Install the Filter
These filters are typically installed on the main water line that goes into your home so that you can have purified water from every single faucet. If you don’t have any experience working with water lines, then you may want to hire a plumber who can easily access and service your water filter when you need.
These filters are placed near the main shut-off valve and near the water heater. This also helps to increase the lifespan of your home’s water heater.
There’s also a difference for water softeners. People often ask if you should install a whole house filter before or after the section with softeners if you have one installed at home. With homes that are supplied through a municipality, then you would install before the softener.
If you have a well, then you can install after the softener to ensure that it has the right flow.
Your plumber may be the best to talk to about where to install and what’s right for your home, as some systems can also be installed outside in the garage or basement.
What’s Needed for Whole Home Filter Installation
If you do plan on installing the filter, then you’ll need some tools and parts to ensure that it gets done like a pro.
These are the parts needed to install a typical home water filtration system:
- Filtration system and all parts included
- Tubing
- Shut-off valve access
- Mounting brackets
- Fittings (push)
- Pressure gauges (optional)
- Bypass valves (optional)
Homeowners who want to install this water filter also need to have a few tools. While some of this may be overkill, it’s important to be prepared for any situation, particularly if you don’t have plumbing experience.
- Screwdriver
- Drill and drill bits
- Adjustable wrench
- Pipe cutter
- Solder supplies
- Bucket
Once you have all these tools, you’ll need to follow the instructions for your water filtration system, but first, you’ll shut off the main water supply and drain any water in your home by opening your faucets.
Benefits of Drinking Filtered Water at Home
Whether you are connected to a municipal water supply or a well located off to the side of your home, your water probably has some sediment and chemicals in it. Have you done a water test? This is an important step to do before you install the water system so you can see how many chemicals and toxins are removed with your new filter.
Removes Chlorine
Almost all water today has some form of chlorine in it. While it may just be a trace, chlorine has been linked to some serious diseases, including Alzheimer’s and other brain diseases. Carbon filter systems remove chlorine and a variety of other toxic chemicals.
Removes Bacteria and Contaminants
If you live in an area that is close to polluted streams and you don’t trust your tap water, you can instantly fix the problem with a whole house filter.
Eliminates Bad Taste or Odors
If you don’t want to drink your tap water, why would you shower or cook with it? Many studies have shown that water with a bad taste or odor likely contains multiple contaminants, including a high percentage of chlorine and lead.
Better to Wash Clothes With
Chlorine-free water is important for taking care of your clothes. Once you start washing with purified water, you’ll start to notice your fabrics seem brighter and don’t wear as much in the washer.
Remove Hard Water
Did you know that some water can dehydrate your skin and hair? If you have issues with poor water quality, then you could also be experiencing dermatological problems. Showering with filtered water could instantly improve any skin conditions caused by contaminated water.
Increases Home Value
New homeowners are actively looking for homes that already have a built-in water filtration system, ensuring that every faucet delivers clean water. These are standard in many housing markets across America so you could be increasing your home’s value considerably just by adding a low-cost whole home system.
Types of Whole House Filters
While there are two main types of modern filters, there are still some manufacturers who have higher-priced and more alkaline systems that have a different process. The most complex systems will have a combination of all five. These are detailed below:
Activated Carbon Filters
This is the most popular filtration system due to its simplicity and ease of use. Carbon filters are known for removing larger particles from water, but they may not be successful in removing chlorine and other microscopic contaminants. It will also improve the taste and odor.
Carbon filters can be found everywhere, and their filtration systems typically involve a quicker setup. However, they may not remove all contaminants as well as reverse osmosis.
Reverse Osmosis Process
To ensure the removal of 99.9% contaminants, homeowners prefer the reverse osmosis systems. These are multi-stage filtration systems that typically combine carbon filters with reverse osmosis membranes that can remove all potentially harmful toxins. However, it also removes all of the minerals too, making the water very acidic.
Alkaline Ionizers
To make water more alkaline, which is anything over a pH of 7.0 and closer to 9.0, there are some filters that have an ionization process or a remineralization process after the filtration. This adds back valuable antioxidants and minerals. It also makes your water softer, which is important for showers.
UV Filters
Ultraviolet filters can treat water just as well as carbon filters, removing different types of bacteria that can cause diseases and problems after long-term use. In addition, it doesn’t add any more chemicals to the water to purify.
Infrared
When you want to soften your water, then you can use ionizers or infrared filters. If your home is in an area notorious for hard water, then this will certainly help. This system uses light and heat to add negative charges to the water, softening it up for your shower or other use.
Features of High-Quality Home Water Filters
What makes the best water filter better than another? There are two main types of filters, and then there are those filtration systems that have additional filtration including UV or infrared. These are some of the features we like to see in the best water filtration system.
Three-Stage or Higher Filtration
Typically, there are two-stage processes that only use activated carbon filters. While these can lower fluoride and remove some bacteria, it doesn’t improve your water completely. For the cost, you should look into a higher multi-stage process that utilizes activated carbon and reverse osmosis water filtration.
Installation Service
You likely don’t want to do this on your own unless you have plumbing experience. Most manufacturers include an installation service anyway so that you don’t void your warranty. If your system doesn’t come with installation, then you’ll likely need to have a good customer service line or a plumber to help if anything goes wrong.
Filter Life / Capacity
With the top water filtration products, you’ll want to look at the types of filters it uses and how many gallons it’s rated for. The best filters typically last for over 120,000 gallons, and if you want the most elite filter, you can even purchase a 1,000,000-gallon type. This is enough for a few years without changing your filter.
Matches Flow Rate at Home
You definitely want to check your flow rate and water source type to ensure that it will work before spending the money on the filter.
UV Ray and Ionization
If you want to add minerals back into your water, you’ll want it to go through a remineralization or ionization process. There is also a UV ray add-on that allows you to process water with light and remove toxins.
Descaler
In some parts of the country, there are other issues besides chlorine and fluoride. With a descaler, you can remove limescale and soften up hard water. It also keeps your pipes clean and free from corrosion.
High GPM
The gallons-per-minute flow rate is based upon what you need for your home, so it depends on how many appliances you have that intend to use the water at once. Most water filters for the home have at least a 10 GPM, but if you want to service your home better or need a higher flow rate, then you want a system that can put out 20 GPM.
Installation Kits
Most filtration systems provide all of the tools, including o rings and brackets to mount your system and get it installed correctly. However, other systems expect you to have your own tools or use their installation service. You should check customer ratings to see how easy it was to install.
Wells and Municipal Compatibility
Not all filtration systems work with wells, so if you need a specific type of system, you’ll have to check specifications first.
Easy Cartridge Change
You definitely want to find a unit that has an easy-to-use housing unit that won’t trip you up if you need to change the cartridges every year. You can look through customer reviews to find which ones are easiest to change out.
Warranty
How long does the warranty last and what does it cover? A lifetime warranty is always best, but you’ll want to check what it covers. If you install it yourself, you could void the warranty yourself.

These are extremely high-quality filters with a multi-stage filtration process that reduces contaminants considerably, probably the most out of the ones that we have found.
The 6-year and 10-year filtration systems both have their benefits to larger homes. However, we prefer to go with a longer life span. This is one of the top whole home water filtration systems that we’ve seen.
