Top 4 Reasons Why You Need a Water Filter

By Jeff Wise Published: July 05, 2021 Updated: June 26, 2025

Drinking water shouldn't spark so much confusion.

But of course, when it comes to our health, we must understand what our best options are.

One of these "best options" is filtered water. Not only is it a great option in and of itself, but it's also undoubtedly the best option anyone has for drinking water.

No matter your lifestyle preferences, there's not much reason to opt for bottled or tap water over filtered water. Especially since bottled and tap water can actively harm your health.

Interested in learning more? Then keep reading to understand four key reasons why you need a water filter. Afterward, you'll wonder why you spent so long without one.

Top 4 Reasons Why You Need a Water Filter

1. Improved Health

Water filters' popularity stems from their ability to filter water. More specifically, they are able to remove a large number of contaminants and minerals.

This is crucial, especially for areas with harder water. "Hardness" of water depends on how many minerals remain in it. While retaining some of these minerals is essential for health, drinking too many minerals can lead to many long-term health problems.

Such problems include respiratory problems, cardiovascular problems, and more. Washing any part of your body with hard water can also cause irritation and dryness, which is detrimental to those with sensitive, fragile, and/or dry skin.

If you think that bottled water will solve your problems, think again. Bottled distilled water may be filtered of all contaminants and minerals, but avoiding all mineral consumption can also be detrimental to your health. Though bottled water can be convenient, it's best to choose filtered over distilled water for everyday consumption.

So if you've been drinking tap or bottled water, make the switch soon. Doing so will ensure that your daily drinking water is well-balanced and clean. All of which is fantastic for your health.

2. Provides Clean, Safe Water Anytime

When you have a reliable water filter at home, you're never at the mercy of boil advisories, water main breaks, or questionable bottled brands.

Whether it's day or night, hot or cold, you have access to water that's been filtered for safety, purity, and peace of mind.

No more wondering if what's coming out of your faucet is safe — you know it is.

Filtered water gives you consistent quality.

You're not dealing with the variability of different city systems, pipes, or treatment chemicals.

Whether you live in an older home with aging infrastructure or a modern build with questionable municipal supply, a water filter evens the playing field and gives you control.

There's also convenience. No more late-night runs to the store when you're out of bottled water.

No more lugging heavy plastic jugs from the trunk into the kitchen.

Just pour and drink just like a Big Berkey. It's a level of freedom and security that's easy to get used to — and hard to live without once you've experienced it.

And finally, emergencies don't catch you off guard.

If your city issues a boil notice, or if your area is hit by a natural disaster, your Berkey filter is still working.

It doesn't need electricity and can filter even untreated sources. That's peace of mind you can drink.

3. Long-Term Investment

Though the occasional one-dollar water bottle seems negligible, purchasing them regularly will rack up costs in the long run. That's unideal, to say the least, especially considering the health benefits of filtered vs distilled water.

Most people need at least eight cups of water a day. Water bottles are generally sold in 16.9-ounce quantities too. Drink enough bottled water to sustain yourself for a day and you've racked up four dollars in a day. All in all, that adds up to about $1460 a year.

On the other hand, drinking filtered water cuts down much of the costs, especially when it comes to transportation and plastic. Removing those barriers alone can save you hundreds and thousands of dollars a year.

Namely, the cost will amount to about two hundred dollars a year. That's a steep difference — a difference that will get steeper for years to come.

Since the best water filter will only need filter replacements, there's a lot less single-use waste to deal with. Instead, you can drink your filtered water for months without worry, knowing that you only need to worry about it a few times a year. 

4. Plastic Waste Reduction

Even if you recycle all your plastic, it's best to not use it in the first place. In the big picture, it's easier to prevent problems than it is to solve them when they happen. That's why it's important for your everyday lifestyle to use as little plastic as possible.

After all, not everyone will recycle their plastic in the first place. And with pleas to improve eco-friendliness increasing, it's even more important to tighten up our habits.

But even if you're not ready to overturn all your habits, buying the best water filtered on the market is both easy and eco-friendly. You won't have to make constant trips to the grocery store and you won't be using up so much plastic.

If you're on the go, you can always store drinking water in a refillable tumbler or thermos and drink from them. That way, you'll eliminate every reason for using bottled water, increasing convenience and lowering your chances of microplastic contamination at the same time.
