10 Best Whole House Water Filters of 2021 Compared & Reviewed

Best Whole House Water Filter

If you do not already have or use a whole house water filter, you need to get one as it provides an easy and cost-effective way of getting filtered water in your kitchen and all other water dispensing points in the house.

Also referred to as the point of entry filtration system, this water filter will connect to the main water line that enters your home. Hence, with the best whole house water filter, you can be sure that you will have and use filtered water throughout the house.

The only problem is that there are various types and models of whole house filters out there. Because we do not want you to waste your hard-earned money on substandard ones, below we review 10 of the best ones and also explain how to choose and install them.

What to Check Before Buying Best Whole House Water Filters?

How to Buy the Best Whole House Water Filter

There are many good point-of-entry water filters in the market, and you only need to look for the following things to ensure you end up with the best one.

1. Water Quality

Before you go out to buy one of these water filters, you will first need to determine your water quality.

Doing this ensures that you know the contaminants that you are dealing with which makes it easy to choose an appropriate water filter.

The best way to determine your water quality is by sending a sample to a lab for testing, but a water quality report from your water supplier can also be very useful.

If you use municipal water, the most common contaminants that you will need to filter out are chlorine, sediments, and chemicals like herbicides, trihalomethane, and pesticides.

For well water, it will depend on where you live and a few other factors, and so it is important to get your water tested. Luckily, many good whole house water filters like 3M Aqua-Pure AP903 can handle both well and municipal water.

2. Filter

Filters are responsible for the actual filtration or trapping the harmful substances, and so they are a crucial factor to consider when choosing a whole house water filter.

Like with most other water filter types there are generally two types of filters to choose from which are carbon and reverse osmosis filters.

Many whole house water filters will have a multi-stage filtration system, and so they will also make use of other filter mediums like ceramic and pleated filters.

Reverse osmosis filters are the most effective as they will get rid of almost 100% of the contaminants to make your water safe for drinking and other uses around the house. However, they are also some of the priciest.

Also, the filter capacity or how much water it can filter before it needs replacement is vital. Here the larger the capacity the better.

Your budget and the contaminants that you have to deal with should guide you when it comes to choosing an ideal filter.

3. Flow Rate

A whole house water filter has to provide water not only for your kitchen faucets but also for the bathroom and other things like dishwasher and washing machines. Hence, it needs to have a good flow rate to ensure that there is enough water for all these household appliances.

Sufficient water flow also ensures that you will not experience a water pressure drop when you open multiple water outlets.

The best water filters for home use are those that have the highest flow rate but to ensure you have enough water when you need it, you should go for something with a flow rate of at least 10 to 15 gallons per minute.

However, there are still some top-notch models like 3M Aqua-Pure AP903 that will give you a superior flow rate of up to 20 gallons per minute.

4. Micron Size

As much as you want a good flow rate, it is also important to make sure that your water filter is effective in filtering out contaminants and other harmful substances.

The effectiveness of a water filter is measured in the micron size that it can filter. The smaller the micron rating the better and the more thorough the filter will be as it means that it can trap tinier contaminants.

Filters that are designed to remove larger contaminants like sand and silt will have a micron rating of around 50 while the highly effective reverse osmosis filter will have a micron rating of 0.0001.

However, it is important to note that the lower the micron rate the slower the flow rate, and so you need to strike a balance between the two.

How Does a Whole House Water Filter Work?

How Does a Whole House Water Filter Work

While different types of whole house water filters will employ different mechanisms or mediums to clean the water, the principle behind them is generally the same. Below are a few simple steps that explain how these water filters work.

Stage 1: Sediment Filter

The whole house filter is attached to your mains water supply and before the water heater line to ensure that all the water will be filtered before entering your home.

When your well or municipal water enters your filtration system, it will first encounter the sediment filter. This filter is designed to trap the large particles like debris, sediment, and silt.

This filter also helps to ensure that the other filters serve you for longer and requires a less frequent filter change.

Stage 2: Activated Carbon Filter

After the sediment filters, the water then proceeds to the activated carbon filter free of the large particles. This filter does most of the filtration, and therefore it is the most important stage of the filtration.

Activated carbon provides a large porous surface, and it has nooks and crannies for trapping contaminants. It will remove what is left of the sediments, most of the chlorine, volatile organic compounds and also bad tastes and odors.

Stage 3: Copper-Zinc and Mineral Filter

As the water flows through the carbon filter, it encounters the copper-zinc and mineral filters that are also vital because they will remove most of the remaining contaminants.

These filters get rid of any remaining chlorine and heavy metals, and they are also useful for removing most microorganisms found in the water. And they will also help to minimize the scale in the water.

Stage 4: Softner/Descaler (optional)

Softeners or descalers are an optional step that some whole house water filters will not have. Most water filters that have this stage will use ion-exchange technology to soften the water.

Some manufacturers will also use a salt-free water softener for this stage to ensure the water maintains its neutral tastes because ion-exchange can make it a little salty.

Stage 5: UV Filter (optional)

Another optional filter that is common in some top-rated whole house water filters is the UV filters. And it is meant to kill any remaining microorganisms, bacteria, and virus that might have not been filtered in the other stages above.

If your water source is the kind that has a lot of bacterial contamination or lots of microorganisms, you need a water filter with a UV filter.

How to Install a Whole House Water Filter?

One thing that you need to know for sure is that a whole house water filter takes more effort to install than others like the under-sink and faucet water filters.

However, you can still do it on your own if you know what to do. Below we provide a list of some of the tools that you need and the steps to follow during installation.

What you need

  • Drill
  • Adjustable wrench
  • Teflon tape
  • Pipe cutter
  • Bucket
  • Mounting brackets
  • Pressure gauge
  • Push fittings
  • Shut-off and bypass valves (optional)

Steps to follow

Once you gather the necessary tools above, here are a few steps to follow when installing the whole house water filter.

Step 1: Turn Off and Drain Water

The first thing that you need to do when installing any filter is to turn off your water. For a whole house water filter, you need to turn it off by locating the shut-off valve and turning it until it closes.

Once this is done you should then drain the water that is already in the pipes, and an easy way to do this is by turning on your kitchen faucet and letting it run until it drains out most of the water.

Step 2: Pick Installation Location

Now you need to decide on the best location to install the whole house water filter. A good location is one that fully accommodates the entire house including the line to the water heater.

Make sure that it is also near the main water source and away from the reach of children and pets. However, also make sure it is still easy to access for filter change and is in a place that leaves plenty of space for doing this.

Step 3: Cut the Pipe

After deciding on where to have the water filter, you should now measure and cut the pipe. Make sure that you measure correctly and mark spots for the pressure gauges and shut-off valves.

Also place a bucket underneath to ensure the water still in the pipe does not wet or damage the floor and then take a pipe cutter and proceed to cut the pipe at the marked spots.

Step 4: Insert Valves

Next step is to insert the shut-off valves by placing them on both ends of the main water pipe. Shut-off valves are important because they are what you will use to control your water during filter replacement.

Also, you can install a bypass valve at this point if you still want to be able to get access to unfiltered water. For example, you might want to use unfiltered water for gardening to prolong the lifespan of your filters.

Step 5: Install Pressure Gauge

Pressure gauges are optional, but they can still be very useful for monitoring the input and output pressure. For the pressure gauge, you will need to install one on either side of the filtration system. Having them allows you to tell at a glance when you need to replace filters.

Step 6: Mount Filter

It is time now to mount the whole house water filter and for this, you can mount it directly on the wall or on plywood panel screwed on the wall using the mounting brackets.

When mounting the water filter, make sure that the sediment filter comes first followed by the others. Most manufacturers will specify the direction for mounting the filters, and it is important to make sure you follow this.

Also, make sure that you install both the input and output fittings on each side of the filter and apply Teflon tape to keep things sealed up so that you do not get any leaks.

Step 7: Reattach Pipes

The last step is to reattach the pipes on the filtration system to the pipes that you cut using compression fittings or compression nuts depending on what you have or prefer. Once this is done you can turn on the water to check for leaks and if there are no any, the job is done.
