Do I Really Need A Whole House Filter?

The need for a whole house filter relates directly to the quality of water you’re receiving. It doesn’t matter if it’s well water or municipal, it definitely contains something that comprises its quality and it absolutely can be improved.

One way to know for sure is testing your water with a home test kit and studying the results closely for one, or more, of the following:

  • Chlorine or Fluoride
  • Heavy metals such as lead
  • High bacterial count

You can also use your senses to observe if your water is turbid or has particles floating.

If you notice any of these situations happening, then you should seriously start using a whole house water filter.

Why Should I Install A Whole House Water Filter?

Well, to answer why, you just gotta know how badly pollutants affect you and everyone in your home.

You may already know Chlorine, for example, being one of the most popular disinfectants used to treat water. You could even find dechlorinated water strange tasting because you’re that much used to it. However, studies tie it with a high risk of bladder cancer.

Fluoride also has a harmful effect as it’s actually linked to bone cancer, and not that many filters have the ability to get rid of it.

Such chemicals, additionally, can really damage your skin and hair with how much they’re exposed to them on the daily. A water filter can grant you the healthier skin and hair you strive for.

Well-sourced water especially is loaded with agricultural wastes, from fertilizers,  pesticides, and herbicides, all the way to bacteria and microorganisms that could very well cause diseases.

Lead as an example of heavy metals, is extremely toxic, or even lethal if its percentage exceeds a very specific limit.

On a brighter side, whole house water filters are more eco-friendly as you’ll be cutting down on plastic water bottles. It will also result in less plumbing issues while giving you safe better tasting water.

What Type Of Whole House Filter Do I Want?

There are a number of factors that you must consider before purchasing a whole house water filter to avoid getting all confused and choose the best possible option for you.

Water Flow Rate

The flow rate directly translates into how much water is filtered through per minute, and consequently the amount delivered to your house faucets. You want a filter that maintains a constant water pressure if let’s say you’re using the shower while someone is washing the dishes.

That’s why you want to pay attention to the water volume your household outlets normally demands at the same time, for example, at mornings when school and work routines take place.

On average, a 10 to 15 gallons per minute flow rate is enough to sustain a common sized house. Larger houses, however, won’t be satisfied with such a rate and in this case, you gotta go with a higher more suitable flow rate.

Filters types and durability

Most typical whole house filters can remove basic contaminants such as chlorine, sediment particles, and materials responsible for foul smell or taste. But there are more specialized models that can take out heavy metals like lead, magnesium, and iron.

You may also encounter reverse osmosis systems that are the holy grail of whole house water filters. They can get rid of almost 100% of all the undesirable chemicals and pollutants making water completely clean and safe to drink and use in any aspect. The downside here is the rather hefty price tag.

While reverse osmosis systems are well worth the pay, some of us just can’t afford it. Which is why smaller units are available as an alternative that you can install under your kitchen sink. But it will provide pure water for a single tap only, a point targeting filter or so to speak.

All previous types can go under the grand title of replaceable cartridge type filters, meaning that you can customize and combine different filters according to your water problems and work best with well water and water containing sediment.

The other major filter type is carbon tank systems which are incredibly durable, require low maintenance, and are most suitable for city water supplies and water that contains suspended particles.


The true measure of a filter’s efficiency is its micron rating. A micron itself is a very small unit that expresses particle size. If a filter has a pore size of 1 micron, this means that it will block out any particle bigger than that preventing it from entering your house water.

Obviously, the lower the micron rating the purer the water, but the dilemma lying here is that the flow rate will also decrease. Generally, whole house filters offer around 1 to 5 microns while reverse osmosis systems go as small as 0.0001 microns.

It’s important to know that this micron rating doesn’t apply to carbon filters as they work via absorption and adsorption.

Cost and Consumption

Both cost and consumption go hand in hand when it comes to whole house water filters. While it might seem like a good idea to buy a cheaper system, if your house consumes lots of water, you’re gonna need to replace filters multiple times which will cost you more on the long run. And if you don’t use that much water, it’s possible for the filter to get clogged up and you’ll end up with a job done poorly.

That’s why you have to consider your house consumption not just the initial cost of your filter. A filter with higher capacity will last longer and is gonna be more expensive, but at least you won’t have to change filters as often.

Balancing your consumption with the filter’s lifespan is the key to a smart money saving choice.


By now, chances are that you already figured that whole house filtration systems are way bigger than the average units. So, you’d be wise to make sure you have enough room to accommodate such a size.

To Wrap it Up…

For me, the Aquasana whole house water filter takes this one home. With its gigantic capacity and amazing filtration efficiency, I know it will back me up for an insane amount of time. However, if you’re looking for a more affordable but still powerful filtration, the 3M Aqua Pure or the Culligan heavy duty filters should do the trick.
