Compare Water Filter Pitchers: ZeroWater, PUR or Brita?
 ZeroWater Filtering Pitcher (Photo credits ZeroWater) Although many efforts are made by our municipalities to treat the water supplied to our homes to kill dangerous microorganisms such as bacteria, viruses and parasites, there can still remain in tap water other harmful impurities such as metals, pesticides, etc. In addition, tap water may acquire some unpleasant taste due to the chemicals, such as chlorine, used during the treatment.
Water filter pitchers can be successfully used to improve the quality of your tap water. They can help eliminate harmful impurities and allow the water find its pleasant taste and transparency while preserving the beneficial salts and minerals. The filters consist essentially of activated carbon and ion exchange resin. Activated carbon has the action to filter the chlorine, certain pesticides and other organic impurities. The ion exchange resin improves the taste and removes odors. It also softens the water and reduces the presence of limestone and metals such as lead, copper and aluminum. It usually takes three to four minutes to filter a liter (about 4.2 cups) of water. There are different types and sizes of water filter pitchers. The 6 to 11 cup models have the advantage of fitting into your refrigerator door. Some brands also offer filtering water dispensers that can contain larger quantities of water. These won't fit in refrigerator doors, but they are still small enough that they can be placed inside the refrigerator. You will find below a description and comparison of three of the most popular water filter pitcher and dispenser brands: Brita, PUR and ZeroWater. The pitcher comparison section you will find below should help you decide which pitcher will respond best to your needs.
Important Note: As mentioned above, water filter pitchers are made to filter tap water that has already been treated by the municipalities for bacteria and viruses. If you want to purify water that has not been treated, such as water from wells, streams, rivers, lakes, etc., then please click one of the following choices, depending on whether you prefer a countertop or under-sink water filtering and purification system:

Comparing Water Filter Pitcher Characteristics:
1FILTERING EFFICIENCY: With regard to filtering capability, the ZeroWater pitchers and water dispensers are no doubt some of the best. Not only do they offer more complete water filtration thanks to the 5-stage filtration system, but they also allow you to verify that the achieved filtering level is acceptable by testing it with the provided TDS meter. Note also that, for added convenience, some models provide a handy dispenser at the bottom of the unit that allows you to access water without removing the unit from the fridge. In terms of filtering capability, the other brands are quite comparable with each other.
2FILTER DURATION: This parameter is a function of the tap water quality. The more your tap water has impurities, the less your filters will last as they will have to "work" harder. Here are the number of filtered gallons of water per filter claimed by the various brands: ZeroWater: 30, PUR: 40 and Brita: 40. But these numbers should not be taken literally since, as mentioned, filter duration depends on the quality of water being filtered. Also, the fact that ZeroWater has the lowest number (30) does not reflect negatively on the ZeroWater brand, given that it is one of the filters that filters best, and hence does a lot more "work" than the others.
3TASTE: Regarding taste, the water produced by Brita and PUR pitchers tastes quite good, and the taste of ZeroWater filtered water is also quite acceptable. This is understandable, as the more complete the filtering process is (like in the ZeroWater case), the less taste your water will have (remember that 100% pure water has no taste at all!).
4WATER QUANTITY: If you need large quantities of filtered water in your fridge, then consider the ZeroWater 23 cup, PUR 18 cup, or Brita Ultramax 18 cup filtering water dispensers which can contain much larger quantities of water than pitchers can. They all fit nicely in the fridge but not in the door.
In summary, when you compare water filter pitchers for filtering your tap water, if you are looking for the ultimate filtering, go for ZeroWater; if you are looking for larger quantities of water, go for either ZeroWater, PUR or Brita water dispensers rather than pitchers; if you are looking for good taste, you can choose anyone as all produce good tasting water; and finally, if you are looking for convenience with acceptable levels of speed, taste, and filtering, go for Brita or PUR.

The sponge-like filtration system is effective in reducing the taste and odor of chlorine. The end result is clean, better tasting and healthier water.

ZeroWater Filter Pitchers and Dispensers
The first layer of filtration with activated carbon removes the chlorine taste and organic impurities from the tap water. The ion exchange stage removes all dissolved harmful metals such as Aluminum, Zinc, Lead, etc. that may be left in the water from public treatment systems or flowing through metallic pipes. The additional three stages of filtration remove all other impurities.
With these filtering pitchers and water dispensers, you don't have to accept purity claims at face value.You can literally test your water yourself with the included TDS (Total Dissolved Solids) meter to ensure that you're getting the cleanest water possible. When the TDS meter indicates zero you have water with 99.999% of chlorine, lead and other impurities removed. Powered by two easy-to-replace 1.5-volt button cell batteries, the TDS also indicates the status of the filter so you know exactly when a filter change is required.
The ZeroWater pitchers selected here have a compact design that can store neatly right in your refrigerator door and can hold 10 or 12 cups of water.
ZeroWater also offers a 30 cup water filtering dispenser.
ZeroWater filters are lab-certified for 22.5 gallons per filter under the strictest conditions, but customers have reported that their TDS meters indicated fiter change not before over 30 gallons of water were filtered. Note that the lower the TDS of your tap water, the longer the filters will last.
