The Best Whole House Water Filter – Clean Water For The Whole Family

If you are in a hurry and just want to find out the best whole house water filter, I recommend the Culligan WH-HD200 filtration system as the best choice.

A whole house water filter removes sediments, metal particles, pollutants, and bacteria from your water as it enters your house. That type of filtration system is ideal if there are issues with high levels of chlorine in your drinking water, or if you want to protect your appliances and plumbing system from sediment buildups. Here are a few product recommendations to help you find the best whole house water filter for your needs.

How Do Whole House Water Filter Work?

A whole house or point of entry water filter will remove impurities from your water as it enters your home. You would typically install one of those filters in your basement, near the point where the main water line enters your home.

Depending on the filtration system you choose, your whole house water filter would remove sediments, rust, metal particles, chlorine, pesticides, and other chemicals. Those filters can also remove microbial cysts responsible for water-borne illnesses.

What Are the Different Filtration Systems Available?

Most whole house water filters use two or three canisters to put water through several filtration stages. These filters typically have a mechanical stage such as a fine mesh or screen that removes large particles and prevents sediments from entering your plumbing system.

These filters typically use activated carbon or similar media. The porous surface of carbon removes chemicals like chlorine.

You should also consider getting a filter that uses a reverse osmosis membrane. According to the CDC, that technology is an effective way of eliminating bacteria from your water

Reverse osmosis filters are more expensive and create some wastewater. They work by pushing water through a fine membrane that removes impurities. It’s the same technique as the one used to remove salt from salt water. 

Is the Installation Process Easy?

I compared different filtration systems to find a way to get rid of the unpleasant taste and odor of my water and found that whole house filters required a more complex installation than other products.

It’s something you can do if you have some experience with DIY projects, but I would recommend looking for a licensed professional if you don’t have the right tool or don’t feel comfortable with cutting plumbing pipes.

You can watch this YouTube video to get an idea of what it takes to install a whole house filtration system:

Here are the steps you would typically take to install one of those filters in your basement:

  • Use the water-supply shutoff valve to turn the water off.
  • Locate the faucet at the lowest point in your home and turn it on to finish draining water out of your plumbing system.
  • Determine where you want to install the filter. Most filters come with brackets so you can secure them on a wall underneath a plumbing line. Install your filter as close to the point of entry as possible to prevent sediments and impurities from entering your plumbing system.
  • Check the clearance underneath the pipe and make sure you can access the filter easily to replace the cartridges.
  • Measure the filter and cut the plumbing pipe with a pipe cutter.
  • Use a reamer blade to soothe the edges of the cut.
  • Install plumbing fittings over the opening you have created.
  • Install the filter. Pay attention to the location of the in and out ports.
  • Secure the filter to the plumbing fittings with the compression nuts or fittings that came with the filter.
  • Tighten the fittings by hand before using a wrench. Make sure the filter is upright and level with the ground.
  • Turn the water valve back on. Let the filter fill up and check the fittings for leaks.

What Are the Pros and Cons of a Whole House Water Filter?

I compared whole house water filters to other filtration systems to determine which option was best for my home. I found that whole house filters are convenient because they filter all the water you use instead of providing you with clean water at a single point like a faucet filter.

It’s a convenient solution if you need to filter the water you use for drinking, cooking, bathing, and even cleaning. 

One of the advantages of a whole house filtration system is that it prevents sediments and chemicals from entering your plumbing system and damaging your plumbing pipes. It also prevents sediment buildups in the appliances that use water like your dishwasher or washer.

It’s an efficient way of eliminating unpleasant smell and taste, and it also eliminates bacteria, sediments, chemicals, and other pollutants. It’s easier to find multi-stage filtration systems that tackle a wide range of issues when shopping for whole house systems.

There are a few downsides to consider:

  • You need to cut through a plumbing pipe to install your whole house water filter.
  • A whole house filtration system cleanses water as it enters your home. An old plumbing system could contaminate your water with rust or metal particles inside of your home.
  • Most whole house filtration systems use carbon spun fiber. That technology can filter down to 25 microns. It’s great for catching sediments, metals, and some large particles, but other smaller particles can still get through.
