Having access to a clean water source is one of the basic human needs. But do you know how clean the water reaching your faucet really is?
In the following article, we present the best water filter pitchers available on the market in 2019. We also explain why it’s better to use a water filter pitcher than drinking bottled water, and the advantages of drinking filtered water.
We also prepared some water filter pitcher reviews for you to look at. All the models we presented are better than your average water filter, and some of them are actually some of the best models you’ll find.
You want to buy a water filter, but you don’t know which to choose? You’ve come to the right place. We’re confident that after reading out water filter reviews and the buying guide you’ll be able to make an informed decision on which one is the best for your household.
What Are Water Filter Pitchers?
Water filter pitchers are self-contained, fully functioning water filters that produce clean drinking water. Water filter pitchers come with a water container capable of holding different volumes, depending on the model.
These filters are usually made out of a lid, one or two filters, and a container with a variable capacity.
Who Should Buy a Water Filter Pitcher
Drinking clean water is essential for everyone’s health, but finding a way to purify your tap water should be one of your priorities. Using water filter pitchers have many benefits, and we believe you will find yourself in the following descriptions. Our team has created this list to help you decide whether you need to have such a unit at your home.
You should buy a water filter pitcher if you:
- Spend too much money on buying bottled water.
Choosing filtered water will reduce your expenses. Moreover, you will know what you drink and whether it was correctly stored. Another alternative is a filtered water bottle.
- Have children
Filtered water is the best way you can protect your children from taking in contaminants and harmful chemicals found in tap water.
- Want to have a healthy lifestyle
Our bodies are made up of more than 90% water. This means that its quality is vital to being in an excellent physical and mental shape.
- Want to save up space in your home
Huge bottles of mineral water with a water dispenser can be a temporary solution to using clean water. Moreover, they take up too much space, which can be frustrating if your home is not that big. A water filter pitcher, on the other hand, can not only stay invisible on your kitchen counter but also exceed the quality of the bottled water. If you do not mind saving space, you can consider getting a top-rated countertop water filter, too.
Why You Should be Using a Water Filter Pitcher
There are a lot of reasons why you should use a water filter pitcher in your home. The most important reason is the purer, healthier water they produce. Another reason is that the water you drink is usually not as clean as you believe.
Tap water travels for miles through a usually old system of pipes before it reaches your faucet. Even though the water might be very clean as it leaves the municipal water treatment facility, traveling through the pipes might contaminate it. All sorts of contaminants can be found in old pipes, and they include bacteria, heavy metals, fungi, microorganisms, and harmful chemicals.
A water filter pitcher is an inexpensive solution to this problem. All the water you put into the pitcher is treated in about 30 – 60 minutes, and most of the harmful contaminants are removed.
3 Health Benefits of Water Filter Pitchers
There are a lot of health benefits for drinking filtered water.
- No Chlorine – Chlorine can be harmful to humans, and a lot of studies have linked chlorine consumption with different illnesses.
- Less Lead – A large amount or even all of the lead present in your drinking water can be filtered. This will lower the risk of contracting a disease brought by lead ingestion.
- No Plastic – Some of the plastic in the bottles used for storing water might be harmful to your health.

3. Waterdrop Chubby Water Filter Pitcher
This Waterdrop water filter pitcher has an advanced 7-stage filtration technology and will get rid of a significant number of contaminants in your water. For instance, this unit will remove sulfur too because it possesses 10 times more absorption capability than other products in its class.
Once you buy the pitcher, it will come with 1 included filter. However, all replacement filters are sold separately by the same manufacturer. When it comes to stability, we consider this product to be a good one, although its base doesn’t have a silicone-ribbed base to prevent slipping.
As far as maintenance goes, the pitcher can be taken entirely apart and can be washed by hand. It is important to note that the filter has to be soaked in cold water for at least 10 minutes before the first time you use the unit.

Water Filter Pitcher Buying Guide
No matter how pure you think your water is, the truth is that tap water often contains chemicals that you should not be drinking. Water filtration drastically reduces lots of contaminants like disinfection by-products, nitrate, lead, perchlorate, and many more.
There are a ton of water filters on the market and choosing the right one can be a tough job.
What to Consider When Buying a Water Filter Pitcher
This is because there is a lot to consider before investing your money in the right solution for your home. Here are a few questions that you might want to ask.
Do you know what’s in your tap water?
There are many ways to search for information about your local water system and learn about any contaminants that can be detected in your water supply. If you are concerned about what you learned, then it is time to buy a water filter.
How big is your household?
It is essential to consider this factor, as well. This is because water filters can purify different quantities of water, depending on the brand and price. The bigger your family is, the more water it will consume. Hence, you will need a pitcher with a more significant filtering capacity or a more frequent filter replacement.
How much is too much to pay for a water filter pitcher?
Buying a water filter pitcher is not different from buying a product of any other type. You know your budget, and for the money you intend to spend, you can always find the right solution. However, more expensive units offer better protection against a broader range of contaminants.
Who is going to use the water filter pitcher?
We should note that pitchers can be a bit heavy even when empty. So, imagine how much a full water filter pitcher will weigh. If you have kids at home and they are used to pouring water themselves, then a heavy pitcher might not be such a good idea. The same goes for people who are not that physically strong. Make sure to try holding an empty unit and check whether you feel comfortable with that.
The warranty is essential – some units come with a lifetime guarantee, others with less. But other than that, your choice must be protected.
Apart from an aesthetic point of view, the design of water filter pitchers is essential. Make sure to pick an item with an ergonomic handle to prevent water spills. Also, look at the lip of the pitcher – some models have a lid to cover it. The lid itself is a great thing to keep the filtered water inside the pitcher clean.
Key Features and Specifications of Water Filter Pitchers
Water filter pitchers have all the same function – to purify the tap water you use for drinking. However, different brands come with a variety of features that may or may not be the right for you. That is why our team has compiled a list of the most common characteristics that you may come across while searching for the perfect water filter pitcher.
Capacity for removing contaminants
All water filter pitchers are designed to make your drinking water free of dangerous substances found in tap water. However, some water filters can do more than that. There are units that will remove more than 90% of the fluoride. Other products, on the other hand, have a long list of contaminants that can be purified.
Boosting drinking water quality
Apart from purifying tap water, some units can add up more benefits to your health. You can find pitchers that are specifically intended to release minerals while filtering the water making it more nutritious.
Reminder for changing the filter
We think this feature is vital because you will not bother to remember when you last changed the water filter.
Some products have excellent purifying characteristics, but at the same time, filter the water very slowly. It is more likely to experience this with a pitcher working with one filter rather than with a unit using two filters.
Number of filters in the pitcher
As you may have already noticed, there are pitchers with two operating filters at the same time. This is extremely convenient and beneficial to the quality of the filtered water. However, such water filter pitchers might not be appropriate to be used for any other type of water except tap water. Other water sources may easily clog the filters and hence require more frequent maintenance.
The material of the Pitcher
A high priority should be the durability of the pitcher itself. However, some units add up to the quality standard of the used materials. You can find pitchers made of ABS plastic or even ones designed with food-grade materials.
How Do Water Filter Pitchers Work?
Water filters use an activated carbon filter or a cartridge filter to block the contaminants flowing in the water. When you pour water into the pitcher, it will first enter the filter where the contaminants are removed. The water then slowly drains into the actual water container. When you want to pour the water into a glass, a bypass system allows it to exit the pitcher without passing through the filters on its way out.
What Is A Carbon Filter?
A carbon filter is usually produced from coconut shells, coal, lignite, wood, or petroleum pitch. The activated carbon is produced using one of the following processes
Physical Activation Through Carbonization
During this process, the source material is activated at temperatures between 600 – 900 degrees C (1112 – 1652 F) in an inert atmosphere, usually in the presence of nitrogen or argon.
Physical Activation Through Oxidation – The source material or the previously carbonized material is exposed to oxygen or steam, usually at temperatures between 600 – 1200 degrees C (1112 – 2192 F)
This process differs from manufacturer to manufacturer, but the principle of the process remains the same. Before the source material is carbonized, it is impregnated with different chemicals. The chemicals used are usually strong acids, bases, or sometimes salt. Most manufacturers use potassium hydroxide, calcium chloride, sodium hydroxide, and zinc chloride for this process.
Impregnating the source material before the carbonization makes the raw material easier to activate. Usually, the carbonization temperatures are lower (450-900 C) for impregnated materials. This is why the chemical activation is preferred over the physical one because the temperatures are lower, the activation time is shorter, so the manufacturer’s expenses are lower.
How A Carbon Filter Works
An activated charcoal carbon filter works using a natural phenomenon called adsorption. Absorption is the natural tendency of the atoms in a liquid, gas, or dissolved solids to adhere to a surface.
The activated charcoal has a very porous surface, and the nooks and crannies in its surface offer a lot of space for the ions to enter, trapping them. Thanks to its high porosity, a gram of activated carbon offers an adsorption surface of roughly 32,000 square feet.
When the water enters the filter, most of the ions of the contaminants in the water will adhere to the porous surface of the carbon. This will make the water cleaner and healthier.
After a shorter or longer period, the porous surface of the carbon is eventually filled with different particles, so the filter won’t be so efficient at trapping new ones. This is why you should periodically change your filters, as the manufacturers instruct.
Cartridge Water Filters
If you’re looking for a water pitcher filter, you must have noticed that some of them use cartridge filters. What exactly is a cartridge filter?
Well, a cartridge filter is a more advanced filter used by some manufacturers to filter out the contaminants in your water. Even though the cartridge filters use an activated carbon filter, they also use other technologies to provide better-tasting water.
Some cartridges will pass the water through 7 different filtering stages before releasing it into the water container. They use ion exchange resins, mineral balls, activated carbon, and tourmaline to filter the water. Find the best water ionizer for your home with our guide.
Ion exchange resins are actually tiny beads of the resin-filled with sodium particles. When magnesium and calcium particles come across a resin bead, they are attracted to its surface and they adhere to it. The sodium in the beads is exchanged for the new particles, and the magnesium and calcium ions are trapped. The sodium is released into the water, but being in a small quantity, you won’t be able to tell it’s there most of the time.
Mineral balls add minerals to your drinking water. When the water passes through a filter, some of the good minerals it contains are also filtered out. This makes the water poorer in nutrients and less healthy. The mineral balls solve this problem by adding new minerals in the water after it’s filtered. This increases the water’s nutritional value, so it makes it healthier for you and your family.
Tourmaline is a mineral that is capable of conveying a small electric current. This current resonates within the far-infrared spectrum (FIR) with that of the water. This interaction makes the water molecules resonate with FIR frequencies. The frequencies are the same in your body, so your metabolism will increase after consuming water treated with tourmaline.
What Contaminants Do Water Filter Pitchers Remove?
Carbon filters are very effective at removing some contaminants from your drinking water, but they are not capable of removing all the contaminants in a water source all by themselves.
Unlike other filters, carbon ones remove the chemicals and debris by physically blocking or chemically removing them from the water. Here is a list of the particles the activated carbon filter will remove effectively
Usually used as a disinfectant for municipal water, chlorine not only changes the water’s taste, but it is also related to several diseases. Activated charcoal filters will trap most of the chlorine in the water used for chlorine disinfection, so you won’t taste it anymore.
These compounds are usually present in the water as a by-product of the chlorine treatment. The result after chlorine interacts with the organic matter in the water. Many studies have linked these compounds with several illnesses, and governments set limits so they won’t threaten the life and well-being of the citizens. However, it would be better to avoid them at all costs, so a water filter will help in this regard.
Volatile Organic Chemicals
Usually called VOCs, these chemicals are found in the composition of most herbicides and pesticides. The chemicals are used for soil treatment, but some of them will find their way into the water. They might present some problems, especially if they’re ingested by the young or the elderly.
Giardia is a protozoan parasite that causes giardiasis. Giardiasis is an illness that might last up to six weeks. The symptoms include but are not limited to abdominal pain, diarrhea, and weight loss. Some people might also experience fever, vomiting, and blood in their stool. Giardia spreads through its cysts. These cysts can survive up to 3 months in cold water, so once a water source is infested, it’s hard to completely clear it.
Cryptosporidium is another protozoan parasite blocked by the carbon filter. It can cause a gastrointestinal and respiratory illness called cryptosporidiosis.

Changing the water filters for your water filter pitcher will take up to 10 minutes every 2 – 3 months, and even though this process will vary according to your model, here is how it’s usually done.
- Fill a bowl with cold water
- Submerge the new filter all the way into in the water and let it soak for 10 -15 minutes
- Take the filter out of the water and drain it a bit
- Put the new filter in the pitcher
- Fill the pitcher for three times and throw away the water to help the carbon filter to activate
- The pitcher is now ready to use.
Water Filter Pitcher FAQs
- What does BPA-free mean?
When you see that a pitcher is made out of BPA-free materials, it means that the plastic used in its construction does not contain chemicals that might seep into the water polluting it.
- How often do I have to change the filters?
The filters will filter out contaminants for more or less time, depending on the contamination level of your water source. If your water is highly contaminated, the filters will clog up faster. Usually, you will only have to change the filters once every 2 -3 months.
- How to know when to change the filters?
The easiest way to tell when the filters need changing is to mark the date you installed them in a calendar, or somewhere you can see. This will be a constant reminder. You can also change the filters if you notice the water is draining slower than usual, or if its taste changes.
