Clear2O CWS100A Water Filtration Pitcher Review

Bottom Line

Owners say the Clear2O Water Filtration Pitcher delivers great-tasting drinking water, while professional tests say it filters out lead and organic compounds. Its hose-fill system filters water faster than most other pitchers. The filter also meters the amount of water you use, and an indicator light alerts you when you have reached the 50-gallon filter life limit. The slim Clear2O's profile holds more water than competing models while fitting nicely in your fridge, users say. There are complaints about compatibility with some faucets. Its replacement filter is the Clear2O CWF1014 (Est. $13).

Breaking it down


Excellent filtering and fast filling. In independent tests, one major consumer organization says that among carafe-style filters, 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 water 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 pitcher fillers. 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.

Durability/cost of ownership

A highly affordable option. Dubbed a Best Buy by one professional testing organization, the Clear2O Water Filtration Pitcher has a low initial cost and costs less over time than most water filtration devices. Its sturdy carbon filters cost about $13 each 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. 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.
