Best Water Filter Reddit Ranked & Reviewed Buyer’s Guide

Filtration Capabilities

The filtration capabilities are unsurprisingly one of the most important factors that you need to look out for when looking to buy a filter.

Of course, there are different reasons why someone will be in the market for a filter, for example, they may be trying to improve the taste or remove the nasty odor of the water they are using and consuming alternatively there are more serious reasons where you have to remove harmful contaminants such as lead and bacteria for example where there is no room for mistakes that can potentially your life and the life of others around you.

Therefore it purely depends on what your needs are, with the more expensive filter system offering on average much better filtration capabilities.

Speed of Filtration

Speed of filtration is something that is important when you happen to be filtering large quantities of water or water that is for some reason very dirty and may, therefore, require multiple runs through the filtration systems. As with the ‘filtration capabilities’ point above if you are looking for a better speed of filtration, the only real solution is to buy one of the more expensive and advanced options for sale.

The more expensive and advanced water filtration systems are first of all larger which allows them to naturally process more water at the same time another aspect that affects the speed of filtration is the type of filter incorporated in the filtration system with some filters being faster than others.

Water Capacity

This point may not seem very important, however water capacity can be extremely useful especially if you live in a household where there is high consumption of filtered water.

The higher the water tank in your filtration system the more filtered water you will be store and leave until needed, rather than having to constantly refill the tank or have to filter the water every time that you need it which is why faucet water filters are not a great option if water capacity is a must.

Some users may decide to pour the filtered water into other containers if their water filter does not have the required capacity however this is not recommended as some containers can contaminate the water if, for example, they happen to be rusty, dirty or start to break down like a lot of plastic bottles do after repeated use.


Size of the entire machine dictates where you can store it, in majority of cases it is not a deal-breaker but it is still important to double-check that the water filter that you are trying to buy is actually going to fit in the location you are planning to place it in otherwise you may be in for a nasty surprise if you, for example, decide to place it in a constrained place such as under your sink.

Additionally, if it is really big in size it can take a lot of space on your countertop and can be a real eyesore that negatively affects the appearance of the entire room that it is located in.

Ease of Installation

You can’t deny that some filtration systems are more complicated than others, but this does not have to mean that they also have to be harder to install. Generally, there are some things that you need to look out for when considering if an appliance is going to be fairly straightforward to install, the first thing is whether you are going to need any or a lot of external tools and parts in order to carry out the installation.

Secondly, you can look at the various parts that are included with the product, generally, the more parts that there is the trickier it will be to assemble and finally you can, of course, check the online reviews to see what other customers think of the installation process.


Durability is a key attribute that you need to be looking for when choosing the best product from this best water filter Reddit ranked and reviewed article. The material is generally the most important aspect that decides on whether a product will be durable or not in the long term, the most durable water filters are made from metal or some kind of plastic.

It is also important to highlight that the durability does not just depend on the intended durability that the product was designed for but also how you use your product if you do not follow the instructions and use it in a way that damages it you should not expect your product to have a lot of durability,

Price & Value for Money

For the majority of people here, the price will ultimately be the deciding factor of whether they go ahead and buy a product.

It is good to take a look at the prices of competing products that are in the same category, for example comparing the more basic or casual products against each other and seeing which ones has the best features that are actually useful as the total number of features is not really important if you personally do not have any use for them.

Moreover, related to the point above, an interesting way of thinking about value for money is how many times are you going to be use something, so for example if you have a $30 water filter vs a $300 water filter if you use the $30 water filter only 100 times that is $0.3 per use while if you use the $300 water filter a total of 10,000 times that is $0.03 per use which means that the more expensive filter is actually better value for money.

Accounting for Filter Costs

Pretty much all water filtration systems require a disposable and replaceable filter in order to work properly which means that on top of the fixed fee that you paid in order to buy the filter in the first place you also need to think about the recurring costs of the filters. There are a couple of factors that affect this, the first is the type of filters that you are going to be using.

The generic or basic filters from the majority of manufacturers are able to filter 100 gallons of water before requiring replacement while the more advanced filters, for example, the PUR LeadReduction filter can only filter through 40 gallons of water before needing to be replaced.

Product Warranty

Finally, you have the product warranty which is apart from offering your protection is a way to see the confidence of the manufacturer in that their own product will not actually break down or that it will perform to the same standards as presented in the marketing material.

Furthermore, it is recommended to look out for product warranties that offer you lifetime support as this is very valuable and guarantees that if you ever have any miscellaneous questions or problems that you will be able to get in contact with the customer service team and get it all sorted out.

Filter Testing Certification

When you look at the labeling on water filter systems, they will often have the NSF as well as an ANSI (American National Standards Institute) logo on them. 

The NSF works alongside the ANSI and the product manufacturers to help establish what consumers should expect from a good water filtration system. 

Once these standards have been decided upon, tests are carried out by the approved partner, such as the WQA (Water Quality Association). Only when the tests have been carried out will the product receive the relevant certification that has met the standards set. 

Standard 42, set by NSF and ANSI, is used to certify that the taste and odor of the water passing through systems with this certification has improved. It is the easiest of all the standards set and can easily be met using activated carbon. You will find that most water filter systems will come with this certification.

Any water filter system with a Standard 42 certification can capture particles in water that measure up to half a micron. Not only does this mean it will help remove sediment from the water but most microplastics as well. 

For such certification to be attained, the water filter system will undergo three tests. Throughout these tests, the system’s performance must remain consistent according to how long the filter cartridge is meant to last. 

Do You Need a Water Filter? 

In the US, all public water supplies are tightly regulated by the EPA (Environmental Protection Agency) through the Safe Drinking Water Act. 

The Safe Drinking Water Act helps to ensure that all water leaving water-treatment plants meet their very strict quality standards. 

In addition to ensuring that any contaminants are removed from the water, this act also helps to make sure that contaminants are not able to infiltrate the system after leaving the water-treatment plant.  Companies that provide water to your home must ensure that all pipes leading from their plants are kept in good working order. 

Water supplied throughout the US to homes and businesses is considered to be safe. 

However, if you want to find out what is in the water coming into your home after it has left the treatment plant, go online and search for your local water supplier’s consumer confidence report. This report is something that all suppliers of water must produce as mandated by the EPA. 

Since there is a slight chance that water becomes contaminated after leaving the plant, you may want to consider getting the water coming into your home tested. You can either use a home test kit or arrange for a local water quality laboratory to carry out the test for you.

Another thing you need to be aware of is that if you live in an older house, then the risk of the water coming into your home being contaminated after leaving the treatment plant is higher. This is because homes built before 1986 tend to have plumbing fixtures made from lead.


Why Should I Use a Water Filter?

There are many advantages to using a water filter, the biggest one is that it can remove dangerous particles in your water that can you feel ill.

Another advantage of using the water filter is that it makes the water a lot more pleasant to drink by removing nasty odors and tastes that may have been present due to contamination which can occur from the source of the water and also where it was transported.

How Often Do the Filters Need to Be Replaced in a Filtration System?

There is no straight answers to this as it depends first of all on the instructions set out by the manufacturer of the filters, generally, the majority of filters need to get replaced after two to three months of use however there are others that can last for a few months longer.

Apart from that it also depends on how often you use the filtration appliances in order to filter the water, even though it may say that you need to replace your filters every two to three months this does not mean that you actually have to if you for example only use the water filtration system once a week.

The majority of modern water filters now have a special light that turns on when it is time for you to replace your filter which makes life a whole lot easier.

Do Water Filters Require Professional Installation?

No majority of water filters do not require professional installation as they consist of very few parts and there are clear guides included with the product as well as other guides being available online.

If you happen not to be someone who like doing construction or getting your hands dirty you can get in contact and ask for assistance but it is not a requirement.

Do I Have to Use Official Filters From the Manufacturer of the Filtration System?

All manufacturers of filtration systems recommend that you use their official filters, they also purposely try to make their filters especially so they only fit in the intended machines however there are many knockoffs out there that can fit in your filtration system and seem to be doing the job but you need to be extremely careful as there is no proof that those filters actually work as intended.

How Do the Filters Actually Work?

The majority of filters for filtration machines out on the market made up of different layers tightly packed in a tube-like enclosure, once water passes through there the various layers will do their job by attracting the types of contaminants and sediments that they were made purposely to contain.


Reddit is a great place to gather the opinions and expertise of people all around the world, the six products that we have presented to you in this Best Water Filter Reddit Ranked and Reviewed article are very different to each other and there is no clear winner instead it is about figuring out what characteristics happen to be the most important to you.

Four out of the six products reviewed in this article are fairly cheap, these are the PUR FM-3700 Advanced Faucet Water Filter and the Culligan US 1 EZ-Change Undersink Drinking Water Filtration System which are both faucet water filters and then you have the PUR 11 Cup Ultimate Water Filtration Pitcher, and the Brita Large 10 Cup Water Filter Pitcher which on the other hand are water filter pitchers.

When comparing the two cheap faucet water filters there is a clear winner which is the PUR FM-3700 Advanced Faucet Water Filter which has all of the same features that the Culligan US 1 EZ-Change Undersink Drinking Water Filtration System has and a lot more.

For example, the PUR FM-3700 Advanced is able to filter out a total of 70 contaminants compared to the Culligan US 1 EZ-Change which makes no mention of the exact number that it can filter.

Additionally, although the Culligan US 1 EZ-Change is the best faucet water filter Reddit users claim to have the easiest installation but the PUR FM-3700 Advanced is also a water filtration system that is super quick and easy to install, with the PUR method arguably being better due to the filtration appliance being much lighter and can simply be attached to the faucet rather than having to insert a brand new faucet as you have to with the Culligan US 1 EZ-Change.

Next, we have the two cheapest water filter pitchers, the PUR 11 Cup Ultimate and the Brita Large 10 Cup, these two products are constantly compared. The PUR 11 Cup Ultimate has much better filtration than the Brita Large 10 Cup due to the product having research-backed evidence that shows it that it is able to filter out a total of 70 contaminants found in the water.

Furthermore, the filters of the PUR 11 Cup Ultimate are much cheaper than those of the Brita Large 10 Cup, however, it is also important to note that the filters for the Brita Large 10 Cup also last a lot longer and therefore present better value for money.

Finally, you have the Big Berkey BK4X2 Countertop Water Filter System which is the most expensive water filter presented in this entire article and the Apec Water Systems RO-90 Ultimate Series which comes in at a second place in the price category.

The Big Berk BK4X2 is a very sturdy machine with a large water capacity allowing you to filter up to seven gallons per hour that can then be stored inside for later use. However this durability and large capacity are not useful factors in majority of situations, which is why the Apex Water Systems RO-90 Ultimate comes out on top, it uses a process called ‘reverse osmosis’ in order to filter as many contaminants from the water as actually possible making it the better water filter at filtering which is why it comes out on top out of the two.
