3️⃣ Eliminates Harmful Contaminants

Your water supply (if it’s from well or city water for instance) may be polluted with chemical contaminants like chlorine, lead, iron, magnesium, calcium, etc.

These are dangerous, may cause several health risks, cause poisoning, etc, and badly affect your daily activities like cooking, washing, etc.

Whole house water filters effectively and efficiently reduce all these impurities and types and levels of contamination and give healthier and safer water for drinking and other purposes. 

4️⃣ Eliminates Toxins

There could be several hidden toxins in the water. They may cause problems like dry skin and skin irritation etc. Whole house water filters remove and eliminate such toxins and protect us from the same. 

5️⃣ Helps in Water Softening

Whole-house systems can easily soften hard water and bring you better-softened water, which won’t trouble you doing laundry or cause dry skin on consumption, unlike unfiltered water. 

❌ Cons of Using A Whole House Water Filter

Every good thing has a downside, and so do whole house water filters. And I am here to give you all the information you need to make a good and informed decision.

Here are a few cons that I thought you must know before investing in a whole house water filtration system!

1️⃣ Expenditure

The major downside of whole house water filters is that they come with a hefty price tag. They can cost you a minimum of $400-500 initially during professional installation, and that is then followed by regular maintenance, including changing the filter every 12 months.

So, while they may be of much use, they come at a price, and you need to make sure you need them before investing. 

2️⃣ Space

Whole house water filters take up a LOT of space. Not all houses may be enough to accommodate these filters. While some may take a lot of space, options that take up comparatively less space are available. Assess the space available at your place and get one that fits. 

3️⃣ Efficiency

Now, not all filters will work the right way for you. Different filters are designed to work on different kinds of impurities. For instance, if you have a municipal water supply, you probably won’t be needing a filter to kill bacteria and microbes as it is already treated before reaching you.

Things to Note:

You will need to know the kind of impurity causing trouble in your house and then choose one filter that works on that. If you get a different incompatible filter, it will be more or less useless and inefficient for you. 

4️⃣ Capacity

Water filters usually come with a fixed capacity. Most can filter about 50 gallons of water per day. This limits water use. It can cause trouble on days when there’s a need for an increased water supply, like when guests are over or on laundry days. 

5️⃣ Knowledge

Before getting a water filter, you will need to do extensive research and gain knowledge about individual filters, their maintenance cost, capacity, cartridge, GPM flow rate, your tap water quality, and water flow rate (water filtered gallons per minute), etc. This can be a lot tiresome.  

How To Decide Whether A Whole House Water Filtration Will Be Worth It?

Are you sure your household needs a whole house water filter system? Whole house water filters can be a lot of work, from buying costs to installation and maintenance.

It is best to make sure that your decision is the right one. If you live in an old-built house or have outdated plumbing, you’re more prone to consuming unhealthy water. And that is what I’m here for.

I will be discussing and sharing a few steps you can take to help assure you of your choice of getting a whole house water filter. 

1️⃣ Water Analysis

Before deciding on getting a whole house water filtration system, check your water. Analyze the source water quality. Do you even need a whole house water filter, or can just an under-the-counter filter (like placing one under the kitchen sink) solve your problem?

Sometimes all you need is a point filter to get yourself healthy cooking water. What sort and level of contamination like organic compounds or harmful chemicals are present in the water source? Once you know this, you can make an informed decision.

It will also help you find the right filter, specially designed to filter out the variety of contaminants in the incoming water supply and get you safe water. 

2️⃣ Product Reviews

One of the best ways to decide if you want to invest in something is by going through product reviews and consumer reports.

  • How did other people find the product?
  • Did it work for them?
  • Was their experience good?
  • Is it NSF International certified?

A good product review research will help you answer all these questions and make an informed decision. 

3️⃣ Estimated Savings

If your water supply is contaminated (with dissolved metal impurities, agricultural chemicals, etc), you’ll be spending money on temporary water treatment facilities, bottled water, temporary filters, inefficient machines, etc.

Estimate annual expenditure on such stuff and compare it with the overall cost of the whole house filter system. You might notice that this will help you save significantly. And if yes, go ahead and get a filter today!

4️⃣ Choose the Right Fit

Just because someone told you Reverse Osmosis System worked wonders for them doesn’t mean it will surely do the same with you. There are plenty of varieties of filters on the market. While some may be the best fit for you, others might not even work efficiently for your water supply.


The functioning of a water filter depends on the water condition and water contaminant type, etc. Choose the right filter that will treat your water right, target the problematic contaminants in water and be the right fit for your water supply. 

5️⃣ Assess Your Budget

As said earlier, filters come in a wide range of choices and types. The price range also varies as such. You could get a filter for about $200 as well as for $4000. You have to assess your budget, your needs, cost, and your maintenance of the filter. Estimate all these and make an informed and correct decision.
