Zero Water Filter Reviews in 2021


In contrast with other brands, ZeroWater offers a small but worthwhile catalog. But we still wanted to show you only the best. So we brought 5 filter pitchers that were impossible to dismiss. Here’s what we found about each:

1.ZeroWater ZP-006-4 Water Filter Pitcher

Thanks to a 5-stage system that ZeroWater is known for, the ZP-006-4 pitcher cleans your water from every single type of contaminant you can think of. This includes metals, TDS, and disease-inducing bacteria.

The 5-stage filter is NSF certified. This adds up a layer of safety you can rely on. You can check how well the pitcher is working just after using the pitcher along with a TDS meter tool. Even with the dirtiest of tap waters, you can ensure effective cleaning using this filter.ZeroWater-ZP-006-4

Perhaps one feature you will love about this filter is the 6-cup capacity. That’s enough to handle an entire day’s worth of water so you can use it seamlessly for hours on end. And due to its decently small and narrow design, the pitcher fits in any fridge so that you can keep the water cold in the meantime.

To make it even better, the filter boasts a comfortable handle with a practical spout and lid. Opening and closing the lid when filling plus pouring the water on glasses won’t be much of a problem. Even at full capacity, the pitcher will still feel light on the hands and easy to use.

Last but not least, the plastic is completely BPA-free and thick enough to handle several years of use. Its smooth surface makes cleaning easier to prevent even the slightest of contaminants from staying behind.

While the filtering works like a charm, the process feels slightly slow, requiring about 2 or 3 fills with the filter dam before the pitcher below fills up completely. If you want a fast filter, this one may let you down. But otherwise, you will love how effectively it removes unwanted contaminants with little effort.

What We Didn’t Like:

  • An NSF certification ensures a safer and more effective filtering process that makes it a more reliable pitcher.
  • A decently large 6-cup pitcher size is more than enough for most people, as it can handle several glasses of water at once.
  • It is significantly easier to use and handle around when compared to other larger and more uncomfortable pitchers.
  • The addition of a high-quality TDS meter lets you calculate the number of contaminants in the water at any moment.

What We Didn’t Like:

  • The filtering process is slow and somewhat tiring due to the low-capacity water dam.

 


2.ZeroWater ZD-018 Water Filter Pitcher

Even though water pitchers are known for being small and practical, that doesn’t prevent ZeroWater from producing a large and more practical model like the ZD-018. With a 23-cup water capacity, it can sustain a small or medium-sized household with clean water for a day or two.

The pitcher’s practicality stands out for a filtration system with 5 stages. This ZeroWater filter eliminates even the most stubborn of contaminants, ensuring tasty and odorless water on the other side.ZeroWater-ZD-018
The first and second stage removes dust, rust, and other solids, taking away murkiness from the water. The third and fourth stages remove organic and inorganic contaminants, going from metals and non-metals. And the last one will get rid of any remaining solids, cleaning up the water thoroughly.

This filter doesn’t work alone. You also get the chance to enjoy a quality metering system to analyze the amount of TDS in the water. It will help you realize how many contaminants are in the water after filtering it to ensure the water you’re consuming is always clean.

As for the size, its 23-cup capacity is more than enough for mid-sized households. The important part about this design is the small dispenser spout in front. It will let you pour water a lot more easily than with standard pitchers you need to operate with the hand. Considering the size of the pitcher, this is an excellent feature to have.

The lid or filling system won’t let you down either. It boasts an easy-to-open area where you can start pouring water with little effort. Meanwhile, the water will flow through the filter and into the below container when it is ready to be consumed.

We found the spigot to be extremely helpful, but leaky. If you don’t tighten the dispenser spout properly, it may start to leak over time and cause a slight mess on countertops and other surfaces. Apart from that, the pitcher performs like a charm without drawbacks.

What We Didn’t Like:

  • The 5-stage filter from ZeroWater removes all kinds of contaminants that cause murkiness or bad taste.
  • A large 23-cup design lets you store enough water for an entire day or two, making it ideal for heavy drinkers.
  • Thanks to the dispenser design, you won’t have to lift or move the pitcher to pour water on glasses or containers.
  • A practical design makes it ideal for placing on countertops or on fridge shelves without worrying about spills or messes.

What We Didn’t Like:

  • A small defect on the spigot connection may produce a bit of leaking if not properly attached.

 


3.ZeroWater ZBD-040-1 Ready-Pour Glass Dispenser

For large households where small pitchers are not enough, the ZBD-040-1 enters into action as a worthwhile alternative. This pitcher’s 40-cup design is more than enough to sustain even the biggest homes, large gatherings, and even work offices.

This large design is obviously not movable. The filter comes with a cylindrical design with a bowl on top. It can handle 2.5 gallons of water. And it filters decently fast, so you can enjoy clean water without having to wait several hours.ZeroWater-ZBD-040-1

The filter is the same patented 5-stage model from ZeroWater. Removing almost every kind of undesirable contaminant, this filter ensures a pleasant water-drinking experience. It gets rid of visible solids on the water and changes the smell and, more importantly, the taste of the water.

Among the contaminants, this filter removes include chlorine and mercury, rust, dust, dirt, metals, non-metals, and some bacteria. What’s even better about this pitcher is the capacity to filter for several months, so you won’t have to change it consistently like in small options.

As for convenience, the pitcher doesn’t disappoint. You get a top steel lid that is easy to lift so you can fill the pitcher more easily. This matches well with a practical spigot in front. At the right height, this dispenser ensures a more practical and seamless water-pouring experience.

Lastly, the whole pitcher is designed with style in mind. Placing it on your kitchen, living room, or patio will make the environment a lot more pleasant. And that’s without mentioning the high-quality steel base and spigot alongside the glass container, delivering the extra touch of quality you need.

Because it is a gigantic 2.5-gallon dispenser, it becomes heavy and bulky when filled. Moving it around will take a lot of effort, especially with the lack of handles. But if you understand that it is more of a fixed pitcher that doesn’t move, you’ll have a great time with it, considering the size and filtering capacity.

What We Didn’t Like:

  • The 5-stage filter from ZeroWater removes all kinds of contaminants that cause murkiness or bad taste.
  • A large 23-cup design lets you store enough water for an entire day or two, making it ideal for heavy drinkers.
  • Thanks to the dispenser design, you won’t have to lift or move the pitcher to pour water on glasses or containers.
  • A practical design makes it ideal for placing on countertops or in fridge shelves without worrying about spills or messes.

What We Didn’t Like:

  • A small defect on the spigot connection may produce a bit of leaking if not properly attached.

 


4.ZeroWater Round Water Filter Pitcher

When you don’t need to store too much water, you use a small pitcher that filters well and feels easier to use. The Round 8-cup filter from ZeroWater is precisely that kind of pitcher.

At only 8 cups or 0.5 gallons of total capacity, the pitcher is smaller than other ZeroWater models. But that comes with an advantage: the filter is more practical as it fits anywhere on the countertop, on tables, desks, and obviously, the fridge.ZeroWater-Round

This design has other features worth considering. One comes in the comfort of the handle. With a curved shape and sizeable space, handling the pitcher becomes a no-brainer. This matches well with the easy-to-open lid, boasting a small overlapping lid you can use to fill directly from the faucet with no spills.

Despite the size, this pitcher still boasts the 5-stage filter removes about 99% of all TDS in the water. In comparison with other filters of the same caliber, this one is a lot more effective. And this includes the bacteria-inhibiting layer, cleaning the water a little more thoroughly than competitors.

To ensure the water is always clean, you’ll get the addition of a TDS water meter. It can help you check for unwanted contaminants in the water, so you can be sure that the pitcher is doing the job. It also works wonder to find out when the filter is ready to be replaced, making it a super-handy addition.

While the top cover is practical, it feels flimsy. We found it a bit frustrating to use in some cases, especially when we were trying to fill it up fast. But with proper and patient use, the pitcher won’t present a single problem, becoming a go-to option for convenience seekers.

What We Didn’t Like:

  • It removes typical contaminants like TDS and reduces the amount of lead and copper on the water.
  • The small and practical design saves a lot of effort and space that other bulky and inconvenient models don’t.
  • We found the addition of a water TDS meter to be an excellent idea as it removes the guessing when calculating the filter’s lifespan.
  • A wide and comfortable handle prevents any type of undesirable feel when using, cleaning, or filling the pitcher.

What We Didn’t Like:

  • A few flimsy parts of the lid could make it a little annoying to use in some cases.

 


5.ZeroWater ZP-010 Water Filter Pitcher

With the option of pouring and dispensing water, the ZP-010 pitcher becomes an instantly go-to choice for anyone who needs convenience. Having two ways to get the water out makes it a lot easier to use, saving time and effort while preventing spills in the process.

The spout for pouring is in the front. It lets you pour without spilling water around, especially with the firm grip-oriented handle the pitcher comes with. But if you prefer dispensers, the spigot located in the back will be a perfect addition. No need to lift the pitcher in the slightest to get water on your glass.ZeroWater-ZP-010

It is a 10-cup or 0.6-gallon pitcher. This size is excellent for small and medium-sized needs. Meaning, it works wonders for households of 1 to 3 people. Sustaining an entire day’s water supply shouldn’t be much of a problem with this one.

The size and convenience level is not everything. This pitcher also boasts a BPA-free plastic construction. It is also resilient and requires no effort to clean. You can keep it clean and giving taste-free water for years.

But if there’s something that you can’t dismiss is the 5-stage filter. ZeroWater delivers the same worth-having filter that removes all kinds of unwanted contaminants from the water. This reduces the murkiness while giving a pleasant taste and smell so you can consume the water worry-free.

When it comes to replacing the filter or just opening the lid to fill the pitcher, you’ll find it very difficult to do so. Because the lid is designed to prevent any spill, it attaches super-tightly to the container, making it hard to take off. While this can be annoying, you can be sure the water will never spurt out.

What We Didn’t Like:

  • Pouring water on glasses or other containers is a no-brainer due to the spout and dispenser this pitcher comes with.
  • We found the 10-cup design to be more than sufficient for small and mid-sized households that don’t need too much water.
  • Considering its size and practicality, it can be an excellent portable pitcher to take in trips and adventures.
  • A narrow design made it fit even in the smallest of spaces like cabinets, countertops, or fridges.

What We Didn’t Like:

  • Because the lid tightens up strongly to the container, it felt extra-hard to take it off when needed.

 


What Does a ZeroWater Filter Remove?

Thanks to a 5-stage filter, a ZeroWater filter removes a wide array of contaminants from the water. This includes metals, TDS, and even bacteria.
Below, you get a list of the different types of particles a ZeroWater filter will remove from your water:

Total Dissolved Solids (TDS)

These are non-organic and organic contaminants that change the appearance of the water. Most TDS include minerals and metals, as well as particles from dirt and dust.

Minerals

The typical minerals you can find on the water include calcium, magnesium, zinc, and sodium. In large quantities, these minerals can add a murky look and a salty taste to the water.

Metals

You can usually find lead, copper, cadmium, arsenic, and mercury on any house’s tap water. However, the readings are astronomical in some places, possibly causing poisoning on those who drink this water.

Chemicals

Things like chlorine, fluoride, chloramine, and PFOA and PFAS are human-made chemicals coming from the use of sanitizers, fuels, fertilizers, herbicides, and insecticides. These compounds could cause mild to severe poisoning with unmetered consumption.

Bacteria

As you can see, a ZeroWater filter can remove practically anything that could make the water unhealthy or unpleasant.

How Does a ZeroWater Filter Work?

But how does this type of filter remove such level contaminants from the water? Well, it is not rocket science. The filter is composed of 5 stages that remove a specific type of particle accordingly. Here’s more about these stages and what they do:

1. Filter Screen

The first layer is a coarse screen that removes all the dirt, dust, and rust particles on the water. Once the water goes through this screen, it ends up a lot clearer than before.

2. Foam Distributor

This one removes any remaining solids that didn’t stay in the first stage. It is typically effective at those small TDS particles that demand a lower micron cleaning capacity.

3. Activated Carbon With Oxidation Reduction Alloy

Chemicals, metals, and other non-organic and organic materials will stay on this multi-layer carbon stage. It also stops bacteria from reaching the pitcher’s container.

4. Ion-Exchange Resin

This dual comprehensive resin removes the remaining metals, non-metals, and other chemical contaminants that affect the water ions.

5. Fine Screen & Non-Woven Membrane

The last stage is composed of an ultra-fine screw and a membrane that gets rid of all the remaining TDS. Each stage has a specific purpose, as you can see. This is to ensure that the water that reaches the container below is utterly clean and ready for consumption.

How Long Does a ZeroWater Filter Last?

Considering the different filter stages and methods of sanitization, how long does one of these filters last?

This depends heavily on the amount of use and murkiness of the water. For example, in places with over 400 TDS in the water, it is possible to get between 5 and 8 gallons of total capacity. But in places with a typical range of 50 to 200 TDS, a filter can clean a total of 40 gallons of water.

If you use the pitcher every day in a place with high amounts of TDS, there’s a high chance you will only get a few weeks’ worths of filtering. In case you rarely use the pitcher and the water is low on TDS, you can get 6 months up to a year of capacity.

ZeroWater vs Brita Filters

After reading our best Zero Water filter reviews, you’re probably wondering whether they are good enough to match Brita filters, another popular brand out there.

Our findings offer a similar experience and results, but ZeroWater comes as the best choice due to its better filtering capacity. Below, we compare some factors in which ZeroWater is the superior choice.

Removal Of Contaminants

A filter that’s incapable of removing common TDS, metals, and minerals from the water is not worth pursuing. Luckily, both ZeroWater and Brita perform well in this matter.
Yet, ZeroWater is the best choice due to its added multi-layer carbon state that prevents bacteria growth. On top of that, Brita doesn’t remove lead or copper, as well as the 5-stage filter from Zero Water, does.

Taste & Odor

Both Brita and ZeroWater filters improve the taste and remove unwanted smells from the water. However, ZeroWater comes out on top by its capacity to remove chemical tastes like chlorine a lot better.

Filtering Speed

Because ZeroWater has 5 stages of filtering, it is slower than a Brita filter. But this lower speed comes with the advantage of better filtering, so its performance eclipses the additional time you need to spend.

Practicality & Ease Of Use

When it comes to pouring and filling the pitcher, you’ll find that both Brita and ZeroWater perform similarly. However, ZeroWater takes the throne due to its wider array of dispenser designs, typically offering a larger water capacity of up to 2.5 gallons of water. The largest Brita filter can only hold 1.5 gallons.

Costs (Initial & Long-Term)

At first, you will find that both ZeroWater and Brita filter pitchers are similarly priced. Having said that, ZeroWater seems to have slightly lower prices, primarily on the bigger containers.
In the long term, however, ZeroWater was a little more expensive. This came down to the 5-stage construction of the filters, making them a bit pricier. On top of that, the effectiveness of the filtering also wears them down faster, so while you get less lifespan and higher costs, they do an excellent job.

So, can you say ZeroWater is more expensive than Brita? If you mind about health and safety, you won’t because you’re paying a slightly steeper price for higher-quality products.

Frequently Asked Questions (FAQs)

Is it safe to say that Zero Water filters are better than Brita?

Yes. While the difference is not necessarily clear, you will still get a lot more for the buck with a Zerowater filter.

Even after reading our reviews and learning a thing or two with the info section, you’re probably still confused about Zero Water filters. This section may help you get rid of that confusion:

Is a ZeroWater filter better than Reverse Osmosis (RO)?

While reverse osmosis delivers a slightly better level of purity, ZeroWater filters don’t waste any water and don’t need any installation. You can’t say the same of RO.

Are ZeroWater filters reliable?

Yes. They’re known for cleaning the water thoroughly, becoming one of the most popular types of water filter pitchers in the market.

How fast is a ZeroWater filter?

You can get 6.5 ounces of water filtering per minute. When compared to other brands, ZeroWater filters perform about 10% slower. But this only means the 5-stage filter is doing the job properly, removing more contaminants than similar pitchers in the market.

Will ZeroWater change the pH of the water?

No. There’s no change in pH after using a ZeroWater filter. When the filter wears down, the pH level of the filter may decrease. This is often a sign the filter needs to be replaced.

Conclusion

Taking a pitcher home that cleans your water on demand won’t be easy. But ZeroWater makes it possible to waste less time and effort while picking.

Once you choose the right one, cleaning your water at home will be a pleasure. But more importantly, you’ll be able to consume spotless water without the fear of disease, poisoning, or undesirable taste. But for that, you need to pick a pitcher that really does the work.

That’s why we hope that with our best Zero Water filter reviews, you learned enough to take a step further and pick an option that meets your standards. Whatever you pick from our list, we’re sure it will be something that doesn’t disappoint.
