Why Choose The PUR Brand?

NSF Certified

Every product on our list comes with a National Sanitation Foundation (NSF) certification. The NSF/ANSI Standard 58 certifies that a water treatment system removes lead and other harmful contaminants.

CleanSensor Monitor

This is a small light on your PUR device that monitors when it is time to replace the filter. Once you being using the filter, the light will flash green. It changes color to indicate that it is time to replace it, approximately every 90 days or 100 gallons. 

MineralClear Filters

PUR filters come with a unique filtration system that includes minerals and carbon to remove contaminants. The minerals give your water a more crisp and refreshing taste compared to standard filters.

Maxion Filter Technology

Each PUR filter on our list below uses the Maxion technology, which has activated carbon, an ion-exchange process, and minerals to purify your drinking water. This technology eliminates over 70 contaminants, including mercury and lead.

Filtered Water on Demand

PUR filters provide you with clean drinking water on demand, whether you are using a pitcher, dispenser, or faucet filter. You don’t have to wait at all since your drinking water is simply run through the Maxion filter before it reaches your glass.

Tool-Free Installation

PUR water filters are easy to install. The faucet filters can be screwed onto almost any standard sink tap without using any tools. The pitchers can be set up by simply filling up the container with water.

If you’re looking for filtered water on demand from a top-rated product, this may be the best choice. We chose the PUR FM-3700 as the best PUR water filter on the market. This model is a faucet attachment model. You can get purified free-flowing water from your sink tap.

This PUR water filter comes with an attractive chrome finish that will fit with most modern kitchen decor. It comes with a 360-degree swivel design so that it fits almost any sink faucet. You don’t need any tools to install it. You just need to screw it into the faucet.

This model comes with the patented PUR MineralClear filter, which uses minerals to filter water and give it a crisp, refreshing taste. This faucet filter removes over 70 contaminants, including lead, mercury, chlorine, and other harmful substances. 

After our testing, we found that this PUR model was very effective for large households since you don’t have to fill up a container. We liked that it was easy to install and even easier to use. One potential downside could be that the flow rate is slow due to the fine filtering process.

One customer exclaimed,

This is the easiest water filter to work and definitely the most stylish!

Pros
  • Easy to install
  • MineralClear filter
  • Chrome finish
Cons
  • Slower flow rate

If you’re looking for a water filter for medium-size families, this might be a good choice for you. My team and I chose the PUR DS1800Z Classic as the best PUR water filter dispenser. This model stores water, and it easily fits into your refrigerator.

This PUR model comes with a spigot and a 1.125-gallon capacity container. You can fill up the container and place it in your refrigerator so that kids and adults can easily fill their cups.

This model comes with PUR’s Maxion technology filter, which removes 99% of contaminants that are 3 microns or larger. This dispenser removes chlorine, mercury, and copper from your drinking water. The filter should be replaced every 40 gallons or around 2 months.

We liked that this model comes with an easy to use spigot system. It is ideal for medium-size families that have children. If you place it on an accessible shelf, children will have an easy time filling up their own cup with filtered water.

One problem that we noticed is that the basic version doesn’t remove lead. PUR offers an advanced version of this model for lead reduction that costs more.

Pros
  • 1.125-gallon capacity
  • Fits on most refrigerator shelves
  • Maxion filter technology
Cons
  • Basic model doesn’t remove lead

If you live alone or have a small family, you might not need a huge container to store your drinking water. We chose the PUR CR1100CV as the best PUR water filter pitcher. It is small enough to fit in your refrigerator. It comes with a simple pour action that makes it ideal for a couple or single-person household.

This PUR model is the first pitcher one that we’ve reviewed. Pitcher water filters are best for small households since they only hold a small amount of water. This model holds approximately 0.7 gallons.

Similar to the previous model that we reviewed, it comes with Maxion filter technology. One difference in this model from the dispenser model is that it removes lead. This pitcher comes with an LED light to let you know when it’s time to change the filter.

We thought that this model was the best choice for couples or a single person since it doesn’t have a large capacity. The filters last for about 30 gallons, which is less than the other models we reviewed.

Pros
  • CleanSensor monitor
  • Fits on the refrigerator shelf
  • Easy pour action
Cons
  • Filters only last for 30 gallons

Convenience and ease of use are two of the things that people look for while shopping. This product covers both of those points. We chose the PUR FM2500V as the best PUR faucet mount water filter.

This PUR model comes with a 1-click installation process that can be mounted to almost any sink faucet. It features a simple click button that activates the filter whenever you want filtered water on demand. If you are just washing dishes, then you can turn off the filtration system.

This model comes with a Maxion filter that removes 99% of lead and 92% of pesticides. Each filter lasts for about 100 gallons. The electronic sensor indicates when the filter should be changed. This model is similar to the first model that we reviewed since it is a faucet mount filter.

One benefit of this PUR filter is that it filters your tap water on demand. You don’t have to fill up any containers. We liked that it comes with a switch to turn on the filtration system when needed. One downside is that it can be quite bulky in the sink.

As Sherri said in her review,

I love how simple it was to attach to the faucet. The water tastes amazing just like bottled water.

Pros
  • Filtration system on/off switch
  • Easy to install and remove
  • Budget-friendly model
Cons
  • Bulky in small sinks

There are two types of faucet mount filters. The previous one that we reviewed is vertical. They have the filter sitting at the upwards. The other type is a horizontal filter, which allows for more space in the sink. We chose the PUR PFM450S as the best rated PUR horizontal water filter.

This PUR model comes with a 2-stage MineralClear filter that removes 99% of contaminants by running water through minerals that improve taste and quality. This model also comes with ion-exchange capabilities that help reduce heavy metals.

PUR designed this model to fit horizontally on your faucet. It gives you a bit more space underneath for washing dishes. Each PUR filter lasts for about 100 gallons or 3 months. Like the other models that we reviewed, this one comes with the CleanSensor monitor that indicates when it is time to change the filter.

One advantage of this model is that it has a low-profile design. We also liked the 3-stage MineralClear filter. It doesn’t allow you to store water, but it gives you filtered water on demand.

As one customer stated,

Easy to assemble and install. Has LED blinking lights that display when it's time to change the filter. Clear drinking water comes out immediately.

Pros
  • 2-stage MineralClear filter
  • Ion exchange technology
  • Filters are changed from the back
Cons
  • Does not allow for water storage

If you’re not searching for a whole new filtration system but rather just new filters for a current system, then check out these replacements. We chose the PUR Faster Basic as the best PUR water pitcher filter replacement.

These replacement filters come in a 2 or 3-pack option. They fit all of PUR’s water filter pitchers and dispensers by screwing them into the top of the lid. These filters come with Maxion technology that uses ion exchange and carbon to reduce heavy metals and other pollutants.

They are easy to attach to your existing PUR water pitcher or dispenser. They don’t require any pre-soaking. Rinse the filter for 15 seconds before use. Each filter replacement comes with the new LockFit filter design. Each filter fits into the upper chamber of your PUR pitcher.

We liked that these replacement filters were easy to install on an existing pitcher. Since they fit all PUR pitchers and dispensers, you don’t need to worry about finding the right size. We also thought they were budget-friendly. They don’t remove lead.

Michael stated in his review,

I use these in two different PUR water pitchers that I use all the time. Use of these is much cheaper than purchasing drinking water in bottles.

Pros
  • 2 or 3-pack option
  • Easy to replace in current system
  • Budget-friendly option
Cons
  • Does not include the pitcher

This model is the most high-tech faucet mount model that we have reviewed. We chose the PUR FM9600 as the best PUR 3-stage water filter. It has multiple filtration stages that will help reduce all of the harmful chemicals in your drinking water.

This model is a horizontal faucet mount unit similar to the previous faucet mount model that we reviewed. This PUR filter comes with a 3-stage system that includes Maxion technology and a MineralClear filter. The advanced MineralClear filter comes with a coconut shell exterior, a carbon block, and a mineral block to enhance your drinking water's flavor.

This model contains the same Maxion technology as our previously reviewed metals, which means that it removes heavy metals as well. It comes in stainless steel or chrome finish.

After testing this model, we can agree that it is the most advanced faucet water filter on our list. We liked that it included both of PUR’s patented filter technologies. It will not work with pull-out or handheld faucets.

Pros
  • 3-stage filtration system
  • MineralClear filter
  • Ion exchange technology
Cons
  • Doesn’t work with pull-out or handheld faucets

If you have a large family and frequently use your refrigerator door to get water, then this might be a good option for you. We chose the EveryDrop by Whirlpool as the best PUR refrigeration water filter. This is the only refrigerator option on our list of products.

This filter replaces water systems in Whirlpool, Maytag, Amana, and other popular refrigerator models. You attach this water filter to the interior of your freezer door where the water and ice come out. It filters both your drinking water and your ice cubes.

This water filter works by using the existing system in your refrigerator and supplying clean water on demand. This model is certified to reduce 28 harmful contaminants in your water supply, including lead and pharmaceutical pollutants.

One factor that we liked about this water filter is that it connects directly to your refrigerator water supply. It also filters the water that makes your ice cubes. It would be best for large families that have a compatible refrigerator. It is a bit more challenging to install than the other models on our list.

Whirlpool recommends this filter. Eliminates a variety of chemicals and makes crystal clear ice. Love it!

Pros
  • Fits directly into compatible refrigerators
  • Lasts for up to 6 months
  • Filters water for ice cubes
Cons
  • More difficult to install 

The PUR Range Explained

In 1986, PUR was founded by Brian Sullivan, a 24-year-old Harvard economics graduate. In 1994, PUR invented the first faucet filtration system with an indicator that showed when the filter needed to be replaced.

Today, the PUR company is still creating innovative water filtration systems and assisting with clean drinking water relief throughout the United States.

Faucet Filtration

This is a budget-friendly option that attaches directly to your sink faucet. It has a switch to engage the filter and run clean water from the tap to your glass. This type of filter offers filtered water on demand for large households. The filters need to be replaced about every 3 months.

Water Filter Pitchers and Dispensers

These filters come with a container that you fill up with tap water. The upper chamber filters the water through an internal carbon filter and then fills the lower chamber with clean water. They are best for small households. The filters need to be changed every 30 to 40 gallons.

Replacement Filters

PUR offers affordable replacement filters for all of their products. PUR water filters are budget-friendly and can be bought in 2 or 3-pack sets. Each filter comes with Maxion, MineralClear, or both technologies.

PUR has partnered with the Whirlpool corporation to make refrigerator filters that fit most of the brand’s models. They offer filtered water through your refrigerator door as well as filtered ice.


Comparing PUR with Similar Water Filter Brands

PUR vs. Brita

Both of these companies primarily offer two types of filters; ones that remove lead and ones that remove only other heavy metals. PUR filters combat more contaminants than Brita. They both have similar offerings such as pitchers, dispensers, and faucet-mount filters. Brita and PUR have similar upfront costs and filter replacement costs. The Brita LongLast filter tends to last longer than PUR.

PUR vs. ZeroWater

Both of these companies have a pitcher and dispenser water filter. ZeroWater does not offer any faucet mount filters, however. ZeroWater delivers a 5-stage filtration system that is superior to PUR's filtration methods. In general, ZeroWater pitchers and replacement filters cost more than PUR. Both companies offer filters that remove lead contaminants.
