Breaking it down


Excellent filtering and fast filling. In independent testing at ConsumerReports.org, the Clear2O Water Filtration Pitcher is the best at reducing contaminants, including lead, disinfectant byproducts and organic particulates. Owners say the resulting water is delicious, with many saying they noticed a distinct improvement in the taste of their water after purchasing this carafe-style pitcher. Even those who bemoan the installation hassles, which we discuss below, say it was worth it in the long run. The Clear2O has a total capacity of 1.75 liters, or nine 8-ounce glasses, yet its slim profile means it doesn't take up a lot of refrigerator space.

Ease of use

Some initial setup hassles; multi-step filling. The Clear2O Water Filtration Pitcher's hose-fill system requires some setup on your kitchen faucet -- a nonexistent step for most carafe-style water filters. The pitcher includes two adapters, one each for inside and outside thread-style faucets. Most users say the adaptors fit their faucet, but some frustrated buyers could not get either one to work. A few were able to find adaptors at their local hardware store; others could not and say they had to return the unit. Once the adaptor is installed, the pitcher is filled using a flexible hose attached to the unit, which is not a hands free process. The hose is also quite short, so the pitcher needs to be able to be set close to the faucet, typically in the sink. A Quick Connect Hose Extender (Est. $10) is available for shallower sinks or for added filling flexibility. The good news is that, because the water is forced through the filter, rather than the gravity-fed drip of most pitchers, this carafe fills very quickly.

Durability/cost of ownership

A highly affordable option. Dubbed a Best Buy at ConsumerReports.org, the Clear2O Water Filtration Pitcher has a low initial cost and costs less over time than most water filtration devices. Its replacement filter, the Clear2O CWF501 (Est. $10), are very affordable and only have to be replaced every 50 gallons -- an indicator turns yellow at 40 gallons, red when it's filtered 50 gallons. How long that takes depends upon how much water you drink, which will depend upon how many people use this pitcher. One caveat on price: at the online retail outlets that we reviewed, prices were all over the place. If you are interested in this pitcher or its replacement filters, you might be better off purchasing directly from the manufacturer. We read a few complaints that the Clear2O seems flimsy or that the hose connector broke after just a few months, but those are in the minority. It's made from BPA-free plastic and is covered by a 90-day warranty.
