Best Water Filter: Pur vs. Brita vs. Zero Water

There are many brands of water filters, each with their own filtration methods and pros and cons. While many people recognize Brita since it’s one of the first in this market, there are many other brands to consider. Here we’ll be comparing three of the top brands right now (Pur vs. Brita vs. Zero Water) to find the best water filter. You’ll find that each one satisfies slightly different needs. We’ll also be looking at some of their iconic and popular products.

1. Pur


Pur has marked itself as one of the top brands in the water filter market. Aside from their units being very compact and easy to fit on a kitchen counter, they also use an LED indicator on their filters and are known for drastically reducing particles from 16 different contaminants. For example, this will remove 97% of chlorine, 96% of mercury, 87% of zinc and many more. You can count on Pur to make your water a little purer.

Another bonus is that the pitcher is BPA free, further shielding you from contaminants. The filter uses the Maxion process. Both coconut shells and activated charcoal are used together to filter out unwanted and harmful particles, trapping them deep in the filter. These filters last around two months or up to 40 gallons, which should be plenty for most homes. Most filters have an easy to open lid that you can lift with only your thumb.


When it comes to drawbacks, there are only a few as they aren’t bad at all. The Maxion process is great at removing contaminants, but it’s very slow. It will take longer than usual for water to feed through the filter and be completely clean.

If you’re on the move and don’t have time to sit around and wait for the water to filter, then this might be a problem. However, if you’re just going to fill the pitcher and let it sit until you’re thirsty, then this should be just fine.

Another drawback is that even though the filter can remove many harmful contaminants, it doesn’t remove fluorides. This is a common inclusion in water, but if you are sensitive to it this may be a problem.

Filters last about two months.

PUR 18 Cup Dispenser: This has all the great features of the Classic 11-cup pitcher. From the high filtration rate to the filter lasting a great 40 gallons or two months, the only difference is that the pitcher holds up to 18 cups of water.

Compatible with standard faucets only.

2. Brita

As one of the first and most popular brands of home water filters, you’ll find that Brita products function to a high standard. The entire pitcher is BPA free, and you’ll love how the filter blocks both smells and tastes from contaminants. Most of the bad taste comes from chlorine, and Brita does a wonderful job of removing this from drinking water.

The filter contains both activated charcoal and ion-exchange resins. The charcoal is made from broken down coconut shells. The charcoal is there to block the common mineral and organic contaminants, while the resins have a larger surface area and block big contaminants like heavy metals.

Another benefit is that the filtration job isn’t just thorough, it’s also very quick. You can expect a whole pitcher to be filtered and ready in less than a minute. Getting the filter started is easy. Just open the top, fill it with water and wait for it to flow through the filter.

Just like Pur, most filters last around two months or 40 gallons, but the filter indicators aren’t quite as good. Some units don’t even have filter indicators, while others have a sticker indicator that isn’t as accurate as an LED one. Regardless, it should be fairly easy to keep track of when to change the filter if you pay attention or write down the date you last changed the filter.

A small drawback is that water is more likely to spill in these pitchers than others, but you should be fine if you’re careful.

Brita Large 18 Cup Dispenser: Holding a massive 18 cups, which is slightly over a gallon, you can easily keep a whole office or family hydrated with this dispenser. A spigot at the end makes filling cups a breeze. This comes with a sticker indicator to keep track of changing filters. The filter is good for 40 gallons.

Brita On Tap Water Faucet: This unit fits over standard sinks and lets you get purified water from your sink. Can accommodate up to 100 gallons, and there’s a lighted indicator to tell you when to change the filter. To change, just pull off the top filter and then put the new one in.

3. Zero Water


Zero Water has a lot going for it. With a laundry list of features and certifications that the other brands simply don’t have, you’ll find that this is both a premium and affordable brand of water filters. Zero Water claims that their filter removes 99.6% of all dissolved solids. Seems a little farfetched, but they have a tool that proves their claim.

Every Zero Water filter comes with a TDS (Total Dissolved Solids) meter that measures particles in PPM (parts per million). The filter works so well that the reading will often be 0, meaning that little or no particles are floating around in your water.

Along with this, they have an NSF certification, showing just how dedicated they are to cleaning up your drinking water. Both Pur and Brita cannot claim this certification. This is done through a patented 5-stage filtration process that uses ion exchange to completely remove contaminants.


This is not a good filter for those with little time to wait. Since this filter is made to remove just about everything except the water itself, it takes a very long time. This is only good if you want something that you can set and drink at your leisure.

Another problem is that there isn’t an indicator of when to change the filter. In general, Zero Water tells customers to change the filter once the TDS starts reporting around 10 PPM. While you should get a good amount of time from your filter, it all depends on the type of water you use. Dirtier water will obviously tax the filter more than clean water.
