Best Whole House Water Filters

To some people, getting a water filter for the whole house is an absurd idea. They understand the need to filter drinking water, but why would you filter your shower water or your dishwasher water. Well, we’ll talk about the many reasons why you should filter all of the water you use later in the article, but for now, let’s start with the basics.

Best Whole House Water Filters

What Are Whole-House Filters?

Filtered water can be created by many different devices in our household, but you’ll have to purchase them separately. If you’d prefer that option, then our best advice is to get a good under sink water filter, because those can really up to your drinking game, as well as your cooking game and washing game.

You can also get faucet water filters if you feel like the permanent installation of anything won’t be a good choice. If you don’t want to add or remove anything from your kitchen, nor modify it, you can use a water filter pitcher, which is essentially a pitcher that filters water.

As you can imagine, it’s not handy to have all of these things separately. Buying them and maintaining them is more expensive, and it’s more work overall. If you want to make sure that your whole house has fresh and filtered water, get a whole-house system that’s going to be connected directly to the water source.

Best Whole House Water Filters

Buying a water filter for the whole house can be a tricky process, especially if you’re not really familiar with the terminology. Now we’re going to go over some of the most popular models of whole house filters and you can keep track of those that you like.

The filters are very easy to replace – you just twist the old ones off and twist the new ones in. The housing is clear, which helps you get an idea of how much gallons can the filter work through. The setup is very easy and you won’t need a plumber to do the whole thing since you need to know how to work with 1“ connections only.

How Does a Whole-Home Filtering System Work?

So, what is the science behind all of these „best whole house water filters“? Let’s go over the basics and see whether there is a certain way these things work that you can use when you’re choosing which water filtering system works best for you.

So, the science behind the water filtering part itself is the same as to any filter, it depends on the technology. It’s either ion exchange, carbon block filter or something similar, but the idea is the same. The difference between a regular filter and a whole house filtering system lies in the way the water gets to the filter.

With these systems, the water gets filtered directly after entering from the mainline, the main water supply, and then it circulates when it is already filtered. Most of these also feature a carbon activated filter that removes odors and tastes. 

Filtered water goes through the plumbing and doesn’t leave any build-up, which ends up being a huge money saver once you realize that no issues have been happening with the plumbing for a while now.

Important Features to Look for in Whole House Water Filters

Let’s go over the most important features you need to check in each filtering product. These are usually highlighted on the packaging, but we’ll talk about the science behind them a bit as well.

Water flow

With whole-house systems, it’s important that the whole house has the water at all times, even the upper floor. That’s why you want a somewhat large flow. If you decide to skip on this feature, you may find yourself not being able to take a shower while someone else is having a bath. 12-16 gallons per minute are the average to look for, and anything above that is fantastic!

The types of filters inside

Of course, these are the most important parts. If possible, aim for a system that has two or three stages, and one of the stages has to be the activated carbon block that does a fantastic job at removing organic compounds as well. Ion exchange filters are great for making your water a bit softer as well, but you can live without them. The pro tip is to find those who have „rough filters“ that are stage 1 and they filter out the big particles that shouldn’t get to the finer methods of stage 2 or 3.

Filter lifetime

First off, don’t believe the manufacturer when they say that a certain filter lasts a certain number of months. The lifetime of a filter depends on your usage. What you should look for is the number of gallons that can be filtered before the filter actually has to be replaced.

Is it certified?

You can mostly guess what a filter removes when you know the types of filters that are included inside, but you certainly don’t know anything about the efficiency. Always look for NSF/ANSI standards that prove a certain filter is worthy of your time.

What Type of a Whole-House Filtering System Should I get?

There are no scientific types of filters out there because they all get categorized by their stages, but there are some questions that you need to ask yourself in order to understand how heavy-duty a filter you are getting should be.

  1. How much flow do I need? How many rooms are there in my house? How many people are going to be using the filter at the same time? Will I use it to clean?
  2. Do I need a high-pressure filter? Is my house a two-floor one or do I support more than two floors? Is my plumbing weak and should I be concerned about the pressure?
  3. How often can I financially afford to change the filters? Should I go for a lifetime over quality or is it a save if I invest in a more premium model?
  4. What is my water like? Do I need to be afraid of all of these contaminants or is there something specific I want to remove from the water?
  5. Do I believe big brands or will I believe user reviews?
  6. How hard can it be to install this? Will I call the plumber so the installation doesn’t make a difference or do I need to take into account that I need to at least have video instructions?

Why a Whole House Filtering System is a Must

Okay, okay, maybe you’re just overwhelmed with the amount of info that we’ve given you or you didn’t expect the price to be so high. Maybe you’re still considering whether you even need a filtering system. Wait no longer, we’ll show you some really straight-forward reasons to get a water filtering system.

Better overall health

When you’re constantly exposed to bacteria and viruses, your body tends to get inflamed much more often. On the other hand, toddlers and elders in the household may feel serious disadvantages and even feel sick most of the time.

Money saver

Don’t forget that buying bottled water is expensive and it’s not eco-friendly at all. That’s why a filtration system does a much better job. It may be a bit complicated to get it going, but once you manage to do that, nothing will stop you from your perfect drinking water.

Great taste

Well, it’s not rare to see that water smells bad or tastes bad, and we don’t want any of that for us or for you. By investing in a whole house filtration system, you will feel quite a lot of benefits and you’ll never feel the need to buy bottled water again.

Better skin health

Your skin hates water full of unbalanced minerals. These can make your skin dry and inflamed and can create issues for those who usually have skin problems. That’s why opting for a filter is a great choice.

Whole House Filtration System Installation and Maintenance

What’s the use of a fantastic gadget if you don’t take good care of it? You’re literally throwing money away as the efficiency of your filter comes down each month. That’s why you need to make sure that you installed it properly and that you’re taking good care of your system as well.

How to Install Whole House Water Filters?

The first step to this process is turning off the water supply for your home. This will make your life easier by avoiding any mess that could happen.

Next, you should get the tools that are labeled in the instructions of your filter, as well as the parts. Make sure to read or watch the instructions once before you go ahead and re-watch each part as you do it. This will give you a better sense of how much time is needed for a certain part.

It’s also a good idea to drain the water from all faucets in your house by opening them. 

Make sure to ask for assistance or call a plumber if you have no idea what you’re doing. It’s better to pay someone and get a proper result than to do it yourself and then have to re-do it completely.

You will now have to install a shut-off valve and a bypass valve. After that goes the pressure gauge and fitting the existing pipe into the system. If they don’t match, use adapter fittings to save the day.

Make sure to apply some grease on O-rings and to screw them on as tight as you can. Flush the water for a few minutes after connecting the system.

How do you Change a Whole House Water Filter?

This question depends on the filter because some of them have stages that can be removed independently, while some need to be completely removed and re-installed according to the steps mentioned in the paragraph above.

If you can replace stages separately, that means that it’s usually a twist-on, twist-off or a screw-on, screw-off type of fixation. This can be done really easily, but make sure to shut off the water supply to make sure everything goes by properly.
