This filter is specially engineered to maximize potent filtration for top performance. Additionally, it’s been designed with a distinct upflow, dual tank functionality that equates to more water staying in contact with the filters for a longer period of time, meaning more time for contaminants to be removed; this design also means clogging will be a thing of the past.

4. iSpring 2-Stage Whole House Water FilterView Price
The iSpring 2-Stage Whole House Water Filter is a point of entry system capable of filtering up to 15 gallons of water per minute for use throughout your entire home. This system provides two stages of filtration and removes up to 95% of VOCs and up to 98% of sediment, chlorine, and other contaminants that cause unpleasant odors and tastes.

5. Home Master Whole House Water FilterView Price
The House Master Whole House 2-Stage Water Filter has a 95,000-gallon capacity replaceable catalytic carbon filter. This system is capable of providing a full year of pure, filtered water for a family of four. The House Master removes 95% of sediment, chloramines, chlorine, chemicals, heavy metals, and other contaminants from city or well water.
The oversized filters that come with this unit improve the water flow rate and allow you to go longer between filter changes. This system also has large filter housings with 1-inch ports to provide the best water pressure possible. The House Master Filter can provide up to 10 gallons of filtered water per minute, and it connects right to the main water line where it enters your house.

The second stage is the catalytic carbon filter for removing chemicals, heavy metals, and unpleasant tastes and odor.
At only 10 gallons of water flow per minute, this system may not provide enough water flow for larger households. Also, keep in mind that this system does not remove bacteria or viruses from your water. If you are on well water, you should have a water test done before purchasing any water filter to determine what types of filtration you need. House Master provides a 2-year limited warranty with this filter.
6. iSpring 3-Stage Whole House Water FilterView Price
The iSpring 3-Stage Whole House Water Filtration System comes equipped with gradient, three-stage filtration.

7. 3M Aqua-Pure Whole House Water FilterView Price

This system reduces contaminants from the point of entry and protects the plumbing fixtures and water using appliances throughout your entire home. It’s also perfect for light commercial or industrial use. The 3M Aqua-Pure will reduce sediment, dirt, rust, and chlorine odors and taste in city or well water.

We love the Sanitary Quick-Change design of this system that allows for fast and easy cartridge change-outs without the need for a filter wrench, and they’re virtually spill free. The unit has a 100,000-gallon capacity and also features a stainless-steel head that allows for sweat in place installation and improves corrosion resistance.
Although this unit is more affordable than many whole house filters, the manufacturer recommends that you also purchase a separate pre-filter system to use in conjunction with this unit to trap large particulates. The unit can be used without one, but a pre-filter will extend the life of your filter cartridge and prevent clogging.
How Whole House Water Filters Work
Whole house water filters (or point of entry filters) are installed at the point where the main water supply enters your home. That means that they filter the water for your entire home, instead of just at the kitchen sink like an under-sink water filter does. Once installed, the whole house water filtration system becomes the point of entry for your home’s water. With a whole house water filtering system, you can provide clean, filtered water to your entire home for drinking, bathing, cooking, and washing your clothes and dishes.
Depending on which system you choose, your water could go through four stages or more of filtration before it enters your home.
- The first stage is usually a pre-filtering step to remove any large particulates in your water, anything that’s about five microns in size. This is a crucial step because it extends the life of your other filters by preventing them from clogging.
- The next stage of filtration is usually an activated carbon filter designed to remove chlorine from the water. Public water is often treated with chlorine to neutralize biological contaminants, but it can leave your water with an unpleasant taste and smell. In some cases, the manufacturer may treat this filter with special substances that provide other benefits, such as silver to give it antibacterial properties.
- A copper-zinc and mineral filter will usually be the next step. This stage of filtration is crucial for removing any remaining chlorine, heavy metals, and some bacteria and microorganisms from the water. It will also reduce the amount of scale in the water.
- Your system may also include a fourth stage of filtration. In some models, this fourth step will soften the water and remove scale without the need for adding salt. Water that contains high amounts of dissolved calcium and magnesium is considered to be “hard water.” Hard water leaves behind mineral deposits that can stain your sinks and toilets and leave residue behind on your skin and clothes when you wash so this can be an important feature if hard water is a problem in your area. However, it’s more common for systems to include a post-filter at this point. A post-filter will remove any remaining tiny particles from your water and improve the water quality even more.
Some systems may also offer UV filtration. A UV filter is designed to kill any viruses, bacteria, and microorganisms that have made it through the previous stages of filtration. This type of filter can be especially beneficial if your home uses untreated well water. You should have your water tested before you purchase your system to see if you need a UV filter.
Consider an instant hot water dispenser to compliment a whole house water filter and provide hot water for coffee and tea instantly.
Advantages of a Whole House Water Filter
One of the key advantages of installing a whole house water filter at your home is the health benefits. These systems filter out unsafe levels of heavy metals, chemicals, sediment, and chlorine that can be hazardous to your health and have unpleasant side effects, like drying out your hair and skin and giving your water an unpleasant smell and taste. In general, a high-end whole house filtration system can remove as many as 30 dangerous contaminants from the water supply before it even enters your home.
Chlorine is added to municipal water supplies to kill bacteria and viruses, and it is probably safe in controlled amounts. However, if you are using chlorinated water for drinking, cooking, washing, and bathing, you are probably consuming more of it than you realize. Chlorine even evaporates into the steam when you shower or bathe, so you’re breathing it in the entire time. That’s why it’s so important to filter all the water that you use in your home, not just your drinking water.
If your water supply comes from an untreated source, such as a well, it could contain microscopic organisms like viruses, parasites, and bacteria. In fact, even municipal water sources have been known to become contaminated from time to time and boil water notices are issued. A whole house water filtration system can remove these organisms, which protects your family from intestinal and digestive problems.
Investing in a whole house water filtration system can be good for your family’s health in other ways, too. Staying hydrated is essential for your overall health and energy levels. When your family has access to an unlimited supply of great tasting, clean drinking water, they will be encouraged to drink more water, instead of reaching for unhealthy, sugar-laden soft drinks.
Whole house water filters are very low maintenance. Generally, once your system is installed, you will have safe, clean drinking water for up to a year before the filters need to be changed. Not only will you save yourself the expense of purchasing bottled water at the store, but you will also be doing something good for the environment, too. Plastic water bottles are causing a serious pollution issue throughout the world, and anything we can do to cut down on their use is crucial for our planet’s future.
Installing a whole house water filter can reduce your need for plumbing repairs, too. The chemicals, minerals, heavy metal, and rust that are usually found can cause damage to your plumbing system. Heavy metal and mineral deposits can accumulate in your appliances that use water, too, like your dishwasher, washing machine, ice maker, and coffee pot. These deposits can significantly shorten the life of such appliances.
Whole House Water Filter Installation and Maintenance
While you may hire a plumber to install your whole house water filter, there’s always the option of installing it yourself. Although it seems like a pretty daunting task, installation with these units is usually fairly straightforward. Once the system is installed, very little maintenance is required the homeowner should be able to change the filters easily when needed.
To install your new water filter yourself, first check the manufacturer’s instructions that were included alongside the unit itself. While there will most likely be a detailed guide regarding installation, we’ll highlight the general steps below.
Necessary Tools and Items
- Water Filter System (who would have thought!)
- Pipe Cleaner
- Pipe Cutter
- Teflon Tape
- Copper Pipe
- Pipe Fittings
- Filter Fitting Adapters
- Ball Valves (Copper)
Whole House Water Filter Installation Steps
- First things first, locate the main water shutoff for your home and and turn it to the off position. Turn on the faucets in your home to drain the remaining water from the pipes.
- Decide on where you’ll be installing the system.
- Pipe cutter in hand, cut the main water pipe.
- After cleaning the pipe inside and out, install the fittings with solder and then connect the adapter fittings to the filter housing with the teflon tape.
- It’s now time to head back over to your main water shutoff valve and turn it to the on position, however, before doing so ensure that the inlet valve on the filter is off. So long as no water is leaking, the inlet valve can be turned on thereafter.
- Finally, the carbon filter in your system needs to be activated. This process differs between systems, so be sure to read through the documentation provided with the unit.
Replacing the Filter
While the process of replacing water filters will differ depending on which system you have, these instructions will give you the general idea of how it’s done. You can always refer to your owner’s manual for more detailed instructions. Your filter should be changed around every four or so months, depending on the manufacturer and how often it’s used. If you notice the pressure of your water has weakened throughout your home, the water filter most likely needs to be swapped out.
- First, turn off the water at both sides of the filter.
- Locate the pressure release button (if applicable) at the top of the pre-filter and press it.
- Using a plumber’s wrench, loosen the housing and remove the old filter.
- After cleaning the inside of the housing, replace the filter.
- Once the housing is screwed back on, turn the water back on.
- Give the new filter a few minutes of water going through it before using the water for drinking or cleaning.
Best Whole House Water Filter Buyer’s Guide
There are a lot of things to consider when choosing a whole house water filtration system for your home. The first thing you should do is send a sample of your water to a lab for testing or purchase a kit at your local hardware store and test it yourself. You can also tell a lot about your water quality just by its odor, taste, and clarity. Your observations and test results will help you determine what types of filtration you need.
If your water has high levels of sediment, be sure to choose a system that has a pre-filter to remove sediment like dirt, rust, and debris before it has a chance to enter the rest of your system. This will significantly extend the life of your filters, prevent clogging, and protect your plumbing.
In cases where the water has an unpleasant chlorine taste and odor, you need a system that utilizes an activated carbon filter. Carbon filters are also good for removing other chemical contaminants, including pesticides and herbicides. This type of filter will have a significant impact on how your water tastes and smells.
When your water test shows the presence of heavy metals, choose a system with a copper-zinc and mineral filter. This type of filter is also beneficial for removing some types of bacteria from the water and reducing scale. The Express Water 3-Stage filter discussed above features a sediment filter, a carbon filter, and a heavy metal filter, so it’s perfect for almost any situation.
Some filters, like the Aquasana 10-Year Whole House Filter, allow you to incorporate a salt-free water softener right into your filtration system. Aquasana also offers an optional UV filter upgrade that is beneficial for removing bacteria, parasites, and viruses from your drinking water. Not everyone will need these extras, but your water test will tell you if they’re necessary.
Another critical factor to consider is the water flow rate of the system you are looking at. For example, House Master system discussed above can only provide 10 gallons of filtered water per minute. For families that don’t consume a lot of water, this may not be an issue. However, if you have a large family, or you like to run your dishwasher or washing machine at the same time someone is using the shower, you will want to go with a system that offers a higher flow rate. The Express Water filter can provide .25 gallons of filtered water per second, so you should never experience any issues with a reduction in water pressure when using this system.
The longevity of the filter cartridge is also an important consideration. Some systems, like the Express Water and the 3-M Aqua Pure, will filter as much as 100,000 gallons of water before a filter change is required. With that capacity, the average family of four could go for about a year in between filter changes. On the other hand, systems like the iSpring 2-Stage model require a filter change every 50,000 gallons, so the family of four would likely go through at least two filter changes per year.
While some units are quite expensive, a whole house water heater is, in our opinion, one of the best investments that can be made, as it benefits the health of your family, increases the longevity of your home, and conserves the planet.
Although there are numerous units out there to choose from, we hope this best whole house water filter guide has provided some guidance in helping you zero in on the unit that is best for your situation – one that removes the specific metals, chemicals, sediment and so on that are prevalent in your water supply.
