Using this dispenser is a breeze, thanks to its easy-pour spigot. Additionally, despite being a large model, it doesn’t take up much room in the fridge or on the counter.
2) Runner Up, Budget-Friendly: Brita Small Metro Pitcher Filter
Running for the spot of best cheap water filter we have yet another Brita product. This one is great for smaller families, lasts a long time, and doesn’t take up much room.
Fill up your Brita filter tank with up to five cups of water. It may not seem like much, but it’s also what allows the unit to fit so nicely into your refrigerator door.

3) Best Water Filter for Backpacking: Sawyer Products Mini Filtration Device
For your next hiking or camping trip, we recommend getting this Sawyer system. It’s compact, easy to use, and effective at keeping you hydrated and safe, even while on the go.
This product isn’t like the ones we’ve reviewed so far. You can use it in three different ways. Firstly, you can use it as a straw to drink directly from the source. Secondly, you can screw it onto most water bottles and drink through it. Lastly, you can drink from the 16-ounce reusable squeeze pouch that comes with the product.
Whatever way you choose to use it, the Sawyer will be your best companion on your next outdoor adventure. It filters out harmful bacteria (for instance, E. coli) and protozoa (such as Giardia and Cryptosporidium), which can wreak havoc on your body. However, it won’t remove chemicals or viruses.

Why Use a Water Filtration System?
Generally speaking, tap water in the United States is safe to drink. However, in rural and low-income areas, that is not always the case. You may remember hearing about Flint’s water crisis in the media. As it turns out, this Michigan city isn’t the only place in the country facing problems with its water supply network.
Millions of Americans don’t have access to clean drinking and cooking water from their taps. Be it because of contaminants like heavy metals (like lead) or harmful microorganisms, tap water isn’t always as safe as we imagine it to be.
One solution is to boil the water with an electric kettle. But this proves time-consuming, doesn’t get rid of all contaminants, and just isn’t very convenient. A water filtration device, on the other hand, solves this problem quite efficiently. The best water filters catch any small particles that should not be in the water in the first place, including lead. Needless to say, this is essential for anyone getting dirty well water into their pipes.
On top of that, some people simply don’t like the taste and smell of tap water. The cheaper filters can also help with that, making tap water taste just like bottled water. And the best part? It’s a great eco-friendly alternative to plastic waste.
What Contaminants Can the Best Water Filter Remove?
Some of the contaminants that a water filter can get rid of include:
Keep in mind that carbon filters remove far fewer pollutants than reverse osmosis filters
Different Types of Water Filters
You’ll find three main types of water filters on the market. They each have their specific purposes, as well as their upsides and downsides. Which one you choose depends on what you need a filter for.
Pitchers and Dispensers
These are the cheapest and most common filtering systems. Dispensers and filter pitchers are your every-day water filters, perfect for getting rid of that disgusting chlorine smell. They’re also super easy to use: fill up the pitcher or dispenser and wait for the water to pass through the filter. You can keep them in the fridge to get clean, cold water.
You should be using this kind of system if you want tasteless water. It’s best used with city tap water. Keep in mind that if your water supply is heavily contaminated, pitchers and dispensers aren’t your ideal purifiers. They may get rid of lead, bacteria, and viruses, but not always so efficiently.
Faucet water filters are also very popular. Once you’ve attached them to your faucet, all you’ll have to do is open the tap and filtered water will flow out. They’re sometimes more convenient than pitchers.
For starters, you’ll get drinking water every time you turn on the tap. That means you don’t have to keep refilling a dispenser. Additionally, this is a great system to invest in if you need purified water for more than just drinking. For instance, you might want quality drinking water for your cooking. If so, fill up your pot with filtered water straight from the tap.
Their only downside is that they’re bulky and require installation, although it’s not a complicated process.
Under-Sink Filtering System
Lo and behold the royalty of filtered water. This kind of system is ideal for water that needs a lot of purifying. It’s most recommended to anyone with old pipes and very poor water quality.
They’re pretty expensive, bulky, and need quite a bit of work in installing them. However, they are definitely worth it, as they can turn any brown, smelly water into tasteless, odorless, colorless water.
Ways of Removing Contaminants
Different water filters have different ways of eliminating contaminants in the water. Here is a quick list with some of those processes:
- Mechanic filters
- Activated carbon filters
- Ion exchange filters
- Ultraviolet-light filters
- Reverse osmosis filters
What Is the Best Water Filter System?: Buying Guide
Before committing to a specific H2O filter, you need to know what features to look for. That’s why we’ve put together this buying guide: so that you don’t get lost in the vast world of filtration systems. The best water filters check off most (if not all!) these boxes.
Know Your Water Source
First things first: what do you want to get rid of from your water? Different water filters are suited to get rid of specific substances. For instance, some pitchers can eliminate lead, but not all. You have to look into this before purchasing any unit.
If your tap water is already safe for consumption and just has a funky taste, you don’t need to spend much money. A dispenser or pitcher will do a great job. If, however, your water supply has heavy metals in it, you’ll need to spend more to get an under-sink water filter. This will keep harmful chemicals away from your organism.
Total ANSI or NSF Certifications
Two organizations test water filters: the American National Standards Institute (ANSF) and the National Science Foundation (NSF).
You’ll know if a certain brand of filters is good if they’ve been certified by one (or both) of these groups. Stick to these units.
But beware! Some brands advertise that they’ve been “independently tested” their products to the standards. However, this doesn’t mean anything and certainly doesn’t guarantee their products work.
Every filter has to be replaced once in a while. They stop being effective once they filter so many gallons of water. When this happens, you must purchase replacement filters and install them, one by one.
Different models have different filter life. The ones that last longer need less hands-on maintenance. At the same time, your filter life will depend on how much work your water needs. In other words, filters cleaning water with a high concentration of dissolved solids will need replacing more often than if they were cleaning already relatively clean water.
For starters, reverse osmosis filters are some of the most expensive models you’ll find out there. At the end of the spectrum, you have pitchers, which are typically the cheapest. Choose the one that’s best for both your budget and your water supply.
Besides looking at the price of the water filter, you should also look at the price of filter replacements. Also, think of how often you will need to replace the water filters. If you’re not careful, you could accidentally be signing up for an expensive water purifier in the long run.
Water Capacity and System Size
You will also have to think about your filter’s water capacity. This applies only to water filter pitchers and dispensers. High-capacity ones are great for large families, but also more expensive and harder to store. Small-capacity ones are cheaper, easy to store, but need to be refilled much more frequently. It’s up to you which one best suits your needs.
If you’re getting a faucet-mount or under-sink filter, you should also consider water pressure. These two filtration systems change how strong the water pressure is on that specific tap. Low pressure can become really annoying after a while.
Flow rate describes how many gallons can be filtered per hour. For example, a countertop filter that has a flow rate of 30 gallons per day will take a lot longer to dispense filtered water than a similar model with a flow rate of 70 gallons per day.
In a nutshell, if you want clean water at your disposal quickly, you need to look for units with high flow rates. Keep in mind these are usually more expensive. It’s all a matter of balancing priorities within your budget.
However, don’t sacrifice water quality for a better flow rate. It’s definitely not as important as other aspects we’ve already covered.
