Clear2O CWS100A Water Filtration Pitcher

With its unique hose-fill design, the Clear2O CWS100A Water Filtration Pitcher delivers water to its slim carafe almost as quickly as it runs out of the faucet, unlike the slow drip of some pitcher-style water filters. Experts say its filtering is first-class and it's the top performer in one professional test. The Clear2O has a total capacity of 1.75 liters and its slender design fits nicely into most refrigerators, say owners. One caveat: it may not fit all types of faucets.


  • Improves water quality
  • Filter-life indicator
  • Long-lasting filter
  • Fills very quickly


  • Can't fill pitcher without attached hose
  • Not compatible with some faucets

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.

With more than 580 reviews the Clear2O Water Pitcher earns an overall rating of 3.9 out of 5 stars. While that may seem a bit "meh," most praise the pitcher's filtering and fast fill-up. Those who are less happy say the hose is too short, it did not fit any of their taps, or it's cumbersome to hold.
