ZeroWater ZP-006-4 6-Cup Water Filter Pitcher

Zero ZP-006-4 6-Cup

The ZeroWater water pitcher with filter is an extremely popular design that's been backed by numerous athletes and celebrities. This water filter pitcher claims to remove 99.6% of all dissolved solids in your tap water, leaving behind nothing but pure and refreshing water. It does this through a patented 5-stage water filter that does not just use carbon filtering but also ion exchange to reduce contaminants.

The filter's five stages remove particulates in the following order.

  • Stage 1 removes any suspended solids that may make your water appear cloudy or discolored. These can be things such as dust or even rust particles.
  • Stage 2 removes any additional suspended solids at a more detailed level.
  • Stage 3 of the five stage water filter begins to remove inorganic compounds such as pesticides, herbicides, mercury, chloramine, and chlorine.
  • Stage 4 is where the removal of inorganic compounds such as dissolve metals non-metals and radiological contaminants occurs.
  • Finally, Stage 5 is another fine mesh that removes even more solids and holds the stage 4 is resin in place.

The life of the filter will depend on the amount of total dissolved solids in your water. Thankfully, ZeroWater provides you with an in-home testing kit for free that lets you see what your initial water quality is. Depending on your initial water quality and the total dissolved solids that you are beginning with your filter can last anywhere from 8 gallons up to 40 gallons or more.

One downside of this water filter pitcher is filter life. Because this water filter pitcher removes so many contaminants, its life is shorter than those of other water filter pitchers that may not be quite as thorough. That means that you will be replacing the filters more often, and replacement filters for ZeroWater are not inexpensive: a single replacement filter for your pitcher will cost anywhere between 12 and $16.

The water pitcher itself has a capacity of 6 cups and is made of food grade BPA free plastic. The pitcher is only 5 in wide which means that it fits easily inside of your refrigerator door compartment. It is just shy of 11 in tall, so it will fit on the middle or bottom shelf.

The filtration speed is moderately fast, and it takes roughly three to four minutes to filter an entire pitcher of water. The water left behind is extremely clear and has no aftertaste. The included water Purity meter that ZeroWater provides does show that the filtered water has zero total dissolved solids.

If you're looking for a mid-range water filter pitcher with a strong filter and are willing to accept the ongoing cost of replacement filters, this is a great choice.

Brita Everyday Water Filter Pitcher

Brita Everyday

Brita is one of the most trusted names when it comes to filter pitchers or water filtration in general, so it's unsurprising that they have some of the best water filter pitchers on the market. A Brita water pitcher can reduce your tap water hardness levels, and the amount of lead, copper, and also chlorine which can affect the taste and smell. Brita everyday water filter pitchers use a single-stage filtration method.

The Brita water filter cartridge is designed to remove larger impurities. Once these are filtered out, the granulated activated carbon, which operates via absorption, removes the other impurities. The activated carbon in a Brita pitcher filter is made from coconut husks. This is a 100% vegan solution, and is also perfectly safe to consume. Brita water filter cartridges do not remove fluoride, so if you are at all concerned about the levels of fluoride in your water, another solution may be best. 

The life of the Brita water filter is roughly 40 gallons, and as this is a 10 cup pitcher you'll need to replace a filter after 64 pitcher's worth of water (640 cups of water)—about every two months based on average household use. The water pitcher is only 5.4 in wide, which means that it is able to be stored in your refrigerator door compartments quite easily.

Operating this water filter pitcher is easy. Or the water in the top reservoir and it will gravity filter through the Brita filter, until the pitcher itself is filled. It takes roughly 3 minutes for the pitcher of water to be ready. The filtered water is extremely clean, and has a pleasant taste and smell.

If your long-term costs are important, some good news: Brita's replacement filters are possibly the least expensive of all the brands that we reviewed, at $14.97 for a three-pack.

In summary, if your tap water is relatively clear and relatively free of more exotic contaminants, this Brita Everyday water filter pitcher is a great budget option.

Levoit LV110WP 10-Cup Large Water Filter Pitcher

Levoit LV110WP 10-Cup

The Levoit water pitcher uses a four stage filtration method to remove impurities such as copper, mercury, and cadmium from your drinking water. The four stages of water filtration according to the manufacturer include an upper micro net, activated carbon, an ion exchange resin, and a lower micro net.

The upper micro net is designed to remove larger particles such as sand, organic matter, and even rust. The activated carbon is granular and removes chlorine—and therefore chlorine taste—from your water, as well as pesticides including Endrin and any residual pollutants. After that the ion exchange resin will remove any heavy metals such as lead, copper, cadmium, or aluminum. Finally, the lower micro net is the final filtration stage, designed to remove any other unwanted smaller particles from the water.

The estimated life of the water filter is 40 gallons. That means that with this water pitcher's 10-cup capacity, you should be replacing the water filter after sixty-four full refills. The water pitcher is made of BPA free plastic, and has a slender 6.7 inch width. This is a little larger than most of the other water filter pitchers we reviewed, but it still does fit in a standard refrigerator door storage area. Empty, this pitcher weighs just less than 2 lb.

The water filter has a timer and filter life indicator to remind you when it is time to change the filter. The indicator has a percentage meter as well as a day meter. The day meter shows the number of days before you should be changing the filter. You can reset the timer if you change the filter ahead of time, or if you decide not to use the pitcher for a while. The cost of replacement filters for this water pitcher is extremely low: a 4-pack of filters is available for $17.99.

Cheap replacement filters and an easy-to-read filter life meter make this water filter pitcher a good choice for large families with space in the fridge.

Brita 36396 Monterey 10-Cup Water Filter Pitcher

Brita 36396 Monterey 10-Cup

This elegantly styled water pitcher has an extremely large capacity and is certified to reduce 99% of the lead content in your drinking water. Additionally, it's proven to remove cadmium, mercury, and even asbestos. It uses Brita has long life filter, which is certified to meet the NSF standards 42, 53, and 401.

You can use both Brita standard filters and Brita Longlast filters for this pitcher. The standard filter uses a three-stage mechanism to filter out tap water contaminants including large contaminants, chlorine, lead, cadmium, and copper. The Longlast filter uses much of the same process, but has an additional proprietary pleated filter and other active filtering agents which helps to extend the life of the filter overall.

A standard Brita filter has a life of two months. The long last filters have the ability to filter up to 120 gallons, which is roughly six months’ worth of water. The size and shape of the water pitcher mean you'll likely need to store it on your primary refrigerator shelf. 

The Brita Longlast water filters are a little more expensive than their standard water filters. Two of the long last replacement filters currently sell for approximately $20. That is in comparison to the standard Brita filters which sell for roughly three for $15. That means that with the standard filters, replacing them every two months will cost $30 a year. On the other hand, the Longlast Brita replacement filters will only cost $20 for the year.

If you're looking at upper range water filter pitchers, Brita is one of the best known brands in the market, and this model is definitely worth a look.

Water Filter Pitcher Buying Guide

pouringNow that you’ve read our water filter pitcher reviews, you have a pretty good idea of what types of water filter pitchers there are and how their filtration methods work. Now it's time to talk about the features and standards that you'll need to know in order to choose the best filter pitcher for you and your family. 

Why Buy a Water Filter Pitcher?

As we mentioned in the beginning of this article, many people don't hydrate enough, and a water pitcher with a filter is a great way to start drinking more. Here are a few reasons why you should look at buying a new water filter pitcher.

  • Better Taste

One thing that pretty much every water filter pitcher does is remove chlorine from your tap water. Chlorine is an inexpensive way to kill bacteria, but one of the drawbacks to chlorine purification is that awful swimming pool residue an aftertaste that you get. Thankfully, it is very easy to remove chlorine from drinking water using activated charcoal. Once you remove the chlorine, you also remove that slightly noxious aftertaste: one of the main reasons people consider buying a water filter pitcher in the first place.

  • Less Contamination

More advanced water filters use multi-stage filtration to remove other contaminants that are found in tap water as well. These include not just physical filtering methods but also methods to remove other chemicals. In short, a water filter pitcher can do quite a bit to help you if you're concerned about toxins and other contaminants in your diet.

  • Less Clutter

No more water bottles! This might seem like a small advantage, but buying fewer bottles of water is obviously easier on your pocket, and goes some way towards freeing up space in your kitchen. If you're really short on space, many water filler pitcher models fit in your fridge door and take up less room than a couple of bottles there.

Bear in mind too that if your family does drink bottled water, a water filter pitcher will be saving you money from the get-go, even when you consider the cost of replacement filters.

Types of Filter

Pitcher filters work in two or more stages, at the physical and chemical level. All the water filters in the pitchers we've recommended combine these two to give you great-tasting water. If you're wondering what the subtle differences are, jump to our section on carbon, ion-exchange and multi-stage water filters below.

When you need to remove sand, sediment, or silt, then you're talking about a physical water filter. The physical filter in your water pitcher will be a fine mesh, or in some cases sand. It can also be pleated paper material. Obviously physical filtration is important in all pitcher filters.

When it comes to removing chemicals other than chlorine, that's when you get into chemical filters. These water filters have been treated with chemicals so that they react to the presence of other unwanted chemicals in your tap water. This reaction causes the contaminants nature to change, and once it is changed the active filter can remove them. The active filter in your water filter pitcher could be anything from activated carbon to an ion exchange resin

Pitcher filters can differ substantially as regards standards compliance, what they actually remove, and cost. When trying to choose your water filter pitcher, try not to get carried away with technology. Bear in mind that the best water filter for you will actually depend on the state of your drinking water, the amount of drinking water you need on hand, and your budget for replacement filters.

Things to Consider When Buying a Water Filter Pitcher

pouring2Now that you know why you should buy a water filter and kind of how water filter pitchers work, let's talk about some of the things that you should be looking at when it comes to choosing the best water filter pitcher for your family. We've made a list of what we think's essential in a water pitcher with a filter. They range from filter size to contaminant removal and filter life and cost.

  • Capacity

It can take up to 5 minutes for a water filter pitcher to filter an entire pitcher, which may mean you'll just forgo drinking water if there's none ready and you don't want to wait. One way to solve this problem is to think about how many cups of water you'll need ready on average, and then ensure that your water pitcher's capacity is large enough that you can always have filtered water on hand.

As a general rule of thumb, for one to two people, a 6-cup water pitcher will be a good size. For 4 people a 10 cup pitcher is a great start, and for more than four you might consider getting a larger capacity system.

  • Contaminant Removal

A tap water test is the best way to know precisely what type of filtration you need. One of the easiest ways to do this is to get a home testing kit. These kits have you take a couple of samples of your tap water and mail them to a testing facility. From there, you can access your results online or get a physical report mailed to you. The report will generally include details of your water's PH and the contaminants in your water, including total dissolved solids (TDS).

Once you're aware of the contaminants in your tap water, you can find the appropriate water filter to remove them. You definitely want to look for a pitcher filter that corresponds to the appropriate ANSI / NSF certification for your specific contaminant and needs. Fortunately, pretty much all water filter pitcher brands are open about compliance, so this information's easy to find. The only real thing you might want to consider is the cost of replacement filters if you're on a budget.

  • Material

In all likelihood, your water pitcher will be made of plastic. There are many different types of plastic, and some are better than others. 

You might have heard that BPA plastics are bad for you: BPA, or bisphenol A, can leach into the water from a plastic container and disrupt various hormones. This disruptive activity on your hormones can have negative effects on you, your children, and your animals.

Still, be cautious even when buying things that are represented as BPA free. That is because many different plastics are made of things that are made of things like BPS, BPF, BPP, and other plastics that have BP in their names: basically bisphenol.

To be safe, first avoid plastics with recycling numbers of 3, 6, and 7. Second, don't ever put your water pitcher in the dishwasher or microwave. This can damage it, and lead to more bisphenol compounds leaching into your filtered water. This is obviously not what you bought your water filter pitcher for!

  • How Long Do the Filters Last?

Replacement filters are obviously a cost concern throughout the life of your water filler pitcher.

The longer a filter lasts before you have to replace it, the less expensive it will be to have clear, filtered water. The flip side is that the better a filter is, the shorter its operational life is going to be. That's because you can only put so much filtration material into the small filter cartridges that come in a water pitcher. 

Another thing that influences water pitcher filter life is how bad your tap water is to begin with. The worse your water is, the shorter your filter's lifespan will be. Recommended replacement times for water filters range anywhere between 2 months and 6 months.

Most water filters now come with some sort of filter life indicator which is helpful, but you should try to keep track of how many times you've filled your water pitcher and use that as a timeframe instead. This will tell you if you should be changing your filter early, or if you can hold off on replacing your water pitcher filter until a later date.

Keep in mind that an unused water filter does not expire. Water filters are rated for a certain volume, so if you haven't used your filter for a couple of months, don't change your water filter out just because it tells you it's been 2 months since your last change.

  • Filter Type

In general, if you have it in your budget to afford a multi-stage filter, get one. That's because the more filtration going on, the better, especially when it comes to filtering water. Here’s a brief overview of the two most common filters that you will find in water pitcher filters. 

Activated Carbon

Activated carbon is great for removing organic compounds from water and dechlorinating water. As we mentioned before, chlorine is routinely added to water to inhibit the growth of disease causing bacteria, molds, and algae that would otherwise flourish in water supplies. However, when you get to concentrations of chlorine that are above 0.3 parts per million, then you can taste it.

Another thing that activated carbon filters are good for is removing volatile organic compounds (VOCs) from water. Because activated carbon is so pitted and has enormous surface area for its size, it can trap a huge amount of compounds that make your water taste awful. Some—but not all—carbon filters can reduce heavy metals too.

However, when it comes to things like calcium and magnesium, an activated carbon filter lets them go through without a hitch. For this reason, water filters rely on ion-exchange methods to remove those impurities.

Ion-exchange Resins

Ion exchange is a purely chemical reaction where certain ions are removed from the water and replaced with other ions that we don’t mind. The resin isn’t a chemical itself and it doesn’t undergo any sort of reaction, it just provides a place where the ions can do the actual exchange. Think of the resin like a local swap meet where things happen.

Multi-stage Filters

These give you the best of both worlds. A multi stage filter will usually start with a fine screen mesh or a layer of fine particulates like sand that will remove the larger particles from your water. After that, a layer of activated carbon will remove the chlorine and other organic compounds. A layer of ion exchange resin will then clean and remove more impurities, while a final mesh layer filters out any large particles that may have been missed.

Keep in mind that if your tap or well water is already fairly clean, then it's possible to choose a water filter that does more than you need it to. If you have soft water, then an ion exchange resin may not be necessary, and the added expense is just money you’re throwing away. That’s why knowing what the specific nature of your water is always good to know. 

  • Warranty

Warranties are a nice thing to have, especially when you have a water filter pitcher made of plastic. If something happens, and the pitcher should crack or start to leak or even if you run into a case where the filters don't fit right anymore, having a good warranty helps to solve all of that. Some companies offer a no-questions-asked free replacement if something happens to the pitcher. Another thing to think about are satisfaction guarantees.

Granular Carbon vs. Carbon Block Filters

Activated carbon is a great material that can make your water taste great. But it comes in two different forms, and while each form does the same job, generally, a carbon block has specific advantages over granular carbon. Likewise, granular carbon has some specific advantages over carbon blocks. Read further to explore the differences between the two.

  • Granular Carbon

This is the most common form of activated carbon that you will find in water filter pitchers. That’s because it’s cheaper to produce. It is extremely good at removing chlorine and VOCs from water, thanks to the extremely high surface area to mass ratio. When untreated water passes through the granular carbon, chlorine and other organic compounds are removed and absorbed into the surface.

One of the drawbacks of granular carbon is its tendency to form channels when water passes through it. This means that the carbon surfaces are quickly used up and the following water isn’t purified or filtered. Another drawback of granular carbon is that it doesn’t form a very good physical barrier to other contaminants. These include larger ions like copper and other heavy metals. Granular carbon is good at one thing and one thing only: removing chlorine and VOCs that affect the taste of your water.

  • Carbon Block

A carbon block is made from the same material as granular carbon, but it is ground into a fine solid mesh that is anywhere from 7 to 19 times as fine as the granular form. Because the carbon is ground that fine, it can form a physical barrier to larger contaminants, including some biological pests like giardia and cryptosporidium. That’s one distinct advantage of a carbon block over a granular form.

Another advantage of the carbon block is that it resists channel formation. This gives you better filtration and a more even wear throughout the entire carbon block.

A disadvantage of a carbon block is that it can get clogged easily. As the water passes through, if the water being filtered has a large contaminant concentration, then it can plug the filter with matter, forcing replacements on a more frequent basis. Additionally, carbon block filters are more expensive than their granular counterparts.

Here’s a short chart showing the advantages and disadvantages of Carbon Blocks vs. Granular Carbon.




Granular Carbon


Great at Chlorine Removal

Channel Formation

Only Removes Chlorine and VOCs

Carbon Block

Physical Barrier removes bacteria and other larger contaminants

Resists Channel Formation

More Expensive

Filter Needs Replaced More Often

Standards and Certifications

kitchenFaucetFillingWhatever you read about water filter pitchers, you're going to hear them say that they adhere to certain standards. You may wonder what those are and why they are so important. In this section we'll give you a brief breakdown on what the five most common standards are for water filtration, and why they should matter to you when you're looking to buy a water filter pitcher. Just bear in mind that there's no real best water filter that covers everyone: it comes down to your particular needs.

To begin with, the NSF is a third party that has developed standards for many different consumer products. Their mission, as they put it, is "to protect and approve Global human health. Manufacturers, regulators and consumers look to the NSF to develop Public Health standards and certifications that help protect food, water, consumer products and the environment."

Whenever a new product comes to market, it's rigorously tested and independent Laboratories according to set standards with very exacting testing protocols. In 1973, the very first NSF standard for drinking water was set.

  • NSF / ANSI Standard 43

This relates to aesthetic events. This is the least stringent NSF standard and refers only to non health-related contaminants, such as chlorine, taste, odor, and other particulates in your drinking water. When a water filter pitcher is certified in this, it means that the picture was tested and found to reduce these aesthetic impurities to adequate levels. This can also apply to whole house treatment systems as well as under the sink and faucet mounted water filtration devices.

  • NSF / ANSI Standard 44

This standard relates to water softeners that use an ion exchange resin. This includes the removal of calcium and magnesium ions, and the replacement with sodium or potassium. This standard should be adhered to by any water filter pitcher that uses an ion exchange resin to treat your water. This will ensure to you that the replacement ion going into your drinking water is not something you should be worried about.

  • NSF / ANSI Standard 53

This standard shows that filters are certified to reduce contaminants that have an actual Health effect. While both standards 42 and 53 cover adsorption and filtration oh, this standard is intended to help reduce microbiological, chemical, or particulate substances that may be present in drinking water. These substances include cryptosporidium, Giardia, lead, and other VOCs.

A VOC, or volatile organic compound, is a compound that is ordinarily a gas at ordinary room temperature. Some of these are known to be dangerous to human health or cause harm to the environment. For example formaldehyde is a VOC that can be present in water, and can have extreme health concerns.

A recent study by the US Geological Survey found that VOCs can be present in about one-fifth of the nation's water supply. While the overall goal is to have no volatile organic compounds in drinking water, in some cases, a maximum contaminant level of .005 parts per million is actually permissible. What this means to you is that if you do a water test and you find that your water is contaminated with a volatile organic compound, you want to look for a water filter pitcher that adheres to this NSF standard.

  • NSF / ANSI Standard 58

This standard doesn't really apply to water filter pitchers. It relates to reverse osmosis systems that use reverse pressure to force water through a semi-permeable membranes. Reverse osmosis systems are usually found and whole-house systems or in water filtration systems underneath your sink.

  • NSF / ANSI Standard 401

This standard addresses 15 contaminants that are on the rise in the drinking water supply in both the United States and Canada. These contaminants are usually pharmaceuticals or chemicals that haven't been regulated by either the United States or Canadian governments. In some cases they are entering the water because of improper disposal, and another case has their entry points into the waterways are unknown.

Water contaminants are usually broken into two categories. The first is aesthetic, i.e. contaminants that don't affect the health of the drinker but do affect the taste, appearance, or odor. The second category is when the contaminant is known to negatively affect the health of the consumer when present in drinking water. An emerging contaminant is a concern that has been raised where the contaminant has an unknown health affect , or the health effect has not been yet established. This standard is for point-of-use and point of entry systems which include water filter pitchers, countertop filters, refrigerator filters, faucet Mount, under sink, and sports bottle filtration systems.

  • NSF / ANSI Standard P473

This standard refers to the ability of a water filter to reduce two types of man-made chemicals—PFOAs and PFOs—in our drinking water. These are chemicals that had been used up until the year 2000 in many industrial and consumer products.

Since 2000, companies voluntarily stop using these chemicals because exposure to unsafe levels can result in health effects that include adverse development of fetus during pregnancy, cancer, thyroid problems, adverse liver effects, and depressed immune systems.

By no means are these the only standards that affect water and drinking water quality. But these are the standards that apply to water filter pitchers. If you are more interested in learning more about the various NSF ANSI standards, you can read more about them on their website here.

  • The Water Quality Association (WQA)

The WQA, or Water Quality Association, is a not-for-profit International Association that represents the water treatment industry. They provide a central point for consumers and businesses to meet and find the best water possible for the environment and for consumers. The WQA represents more than 2,500 manufacturers, suppliers, and dealers worldwide and maintains a list of certified water treatment products.

This list enables consumers to easily search for a water filtration product that adheres to a specific standard that they are searching for. For example, if you are looking for a product that reduces the level of chromium 6 in your water, you can simply type that contaminant into the search field and it will return several products that will suit your needs.

Getting certified by the WQA means that they have reviewed your testing and adherence to the various NSF / ANSI standards and that you qualify for their seal of approval.


When you're trying to live a healthier life and be the best you that you possibly can, hydration is a big part of that. Being properly hydrated gives you more energy, makes you feel better, and makes you look better too. But sometimes, the taste of water gets in the way. Our list of the best filter pitchers and and features have hopefully given you a great starting point to find the best water filter pitcher for you and your family, and giving you great tasting filtered water.

Shopping for a water filter pitcher (or water filter jug for our UK visitors!) doesn't have to be difficult. It may get a little complicated, especially when you start researching the different standards and figuring out what type of water filter you actually need, but in the end it's worth it.
