Buying a whole house water filtration system is one of the best things you can do for the long-term comfort and health of your family. Such a system removes the need for constantly using new countertop or refrigerator filters to clean your drinking water and also makes a great alternative to faucet based filtration systems.
Plus, it works not just for your drinking water, but for all the water your family and appliances use - as a result it also drastically improves your shower experience, since chlorine evaporates with the shower steam and is easy to inhale in large quantities.
But how does one go about choosing a whole house water filtration system? Aren’t there way too many things to consider? Well, there are quite a few variables, yes, but for your convenience, below we’ve reviewed some of the best whole house water filters we could find on the market right now. Check them out!
This RO whole house filter system is a great option and takes first place for people that are looking for a long-term solution for their water and plumbing concerns. It comes with 3 extra filter sets for even more convenience. The system works at 3 stages – the 1st one uses a Premium Quick-Connect 5 micron sediment filter that clears all the dust, dirt, silt, sand, rust and scale particles that are trapped here in a filter, thus greatly extending the life of the whole plumbing system.
The 2nd stage utilizes a Premium 10" GAC granular activated carbon filter that removes chlorine, radon, VOCs (volatile organic compounds) and other common chemicals. This filter also removes cloudiness, offensive odors, colors and unpleasant tastes, which makes it great for improving the quality of life of your whole family.
The 3rd stage uses a 10" Premium CTO carbon block filter that removes chlorine, VOCs (volatile organic compounds, including insecticides, pesticides and industrial solvent). This leads to a significant taste improvement, making your drinking water much healthier and tastier without the need for any countertop or other types of water filters.
The connections of this system are standard 3/4 inch inlet and outlet ports, making it suitable for all standard home plumbing systems. The filters need to be changed every ~3 months.
Our runner-up is a more standard filtration system in terms of both longevity and price, but this is not a comment on its quality in any way. The DuPont universal whole house filter system uses a universal 500 Series poly block cartridge which allows this filtration system to work for up to 15,000 gallons of water. It uses standard 3/4 inch inlets and outlets and it comes with a 3 year warranty.
This filter is great for people that want to try a whole house filter but are not ready for the significant investment that is required for filters of Aquasana’s size. Plus, 15,000 gallons is nothing to sneeze at, particularly at this low price. This water filter system greatly improves not only the health and comfort of your family, but the life of your plumbing and sinks, by reducing the levels of sediment in the water.

This iSpring 3-stage filter brings us to another level and price bracket of whole house filtration systems. We would consider this product more of a long-term investment and solution for your plumbing and water problems and needs.

This here is the Aquasana whole house water filter that you and your family could use for the next 6 years straight. With a capacity of 600,000 gallons, this whole house filter will make you forget what it’s like to constantly buy and replace your water filters, to the point where you won’t want to go back to countertop filters or filtration pitchers.

It also reduces other contaminants including lead, mercury, herbicides, pesticides, and more.

The fittings are made for 0.75 inch pipe but PEX tubing is not included. Of course, as such a long-term filter, it comes at quite the price, but if you consider the long-term value and the high quality, the price is not unreasonable.
Whole house water filters are arguably the best way to ensure that all of the water that you use within your home is safe. Many of us brush our teeth from an unfiltered water supply (our bathroom basins), but wouldn’t it be better if that source of water was as clean as the water you use for cooking and drinking? And those people with skin complaints could even stand to benefit from the use of filtered water in the shower, bath and when washing clothes – removing much of the contaminants that can dry skin out.
The question you should now be asking yourself is, “what type of whole house system do I need?”, a question that we are going to answer throughout the course of this buying guide, in turn guiding you to the perfect whole home water filter for your requirements.
As the name suggests, this type of water filter is designed to filter the water supply of your entire home, regardless of whether your kitchen, bathroom or any number of en suites or utility rooms that form part of your property.
You may be familiar with the term ‘Point of Entry’ system (POE) - which is exactly what a whole home water filtration system is – as your mains water supply is filtered as soon as it enters your property rather than at the point of use as with other forms of water filter.
In this section, we’re going to help you to visualise the way in which most whole home water filters work:
The installation process is slightly more involved than other point of use systems but is still relatively straightforward for anyone acclimatised to home DIY. We suggest following the instructions and ensuring that you choose a suitable permanent location for your new water filter.
In addition, each filter will need to be changed periodically so ensure that you install your system in an accessible location. The process of changing each filter is also straightforward and simply requires you to temporarily switch off the water inlet valve with the entire process taking around 10 minutes.
The flow rate that you require will depend upon the size of your household and the number of occupants’ present. Since this one system is responsible for your entire homes water supply, you will need to ensure that you choose a system that features a sufficient enough flow rate.
Smaller households may be able to suffice with a flow rate of around 10 – 15 gallons of water per minute but a larger property may require an uprated model. If in doubt, we suggest sizing up to future proof your installation.
Your entire water filtration system will be capable of filtering a certain quantity of water before each individual filter will require replacement.
At the lower end of the market, you will find that some smaller systems are capable of filtering 10,000 gallons of water before filter replacement.
At the upper end of the market, many systems are capable of providing your household with over 1,000,000 gallons of clean, filter watered before you even need to think about purchasing a replacement filter.
As a guide, a 500,000 gallon system should last for around 5 years before requiring maintenance.
Whole house water filters are far more capable than any other type of domestic water filter that is available. You will find that even the most basic of systems (2 filters) will be sufficient for a property on mains water whereas we suggest a more comprehensive system if you’re utilising well or borehole water.
If this is the case, make sure that you look for UV filtering and 0.35 micron capability.
In this section, we’re going to summarise the pros and cons of the whole house water filter as a product.
Our product guide in addition to our comprehensive buying guide should now have you in a position where you can decide not only whether a whole house water filter is the right choice for you, but also which model of water filter is most suitable for your water filtration needs.
So, these are our choices for the six best whole house water filters on the market right now. Each one is suitable for different homes and different situations, although our personal pick is the Reverse Osmosis Revolution filter for those who are after a compromise between the heavy hitters and the cheaper models we have reviewed.
Both the Aquasana and iSpring systems would have scored higher if not for their cost. If you are in fact after the best and are willing to make a substantial investment, you can't go wrong with either of them.
