The Clear2O CWS100A is part of the water filter
test program at Consumer Reports. In our lab tests, water filter
models like the CWS100A are rated on multiple criteria, such as those listed below.
Lead removal indicates the percentage of lead that was removed by each filter.
Chloroform removal rates the percentage of chloroform removed. A filter's ability to remove chloroform predicts how well it will remove organic compounds as well as byproducts created by disinfectants used by water systems.
Flow rate is how fast a gallon of water filtered through the cartridge. The criteria for flow rate scores differ between different types of filters. Faucet-mount, countertop, and undersink models have the same criterion; carafes and reverse osmosis models each have their own.

Filter cost Filter cost per year is based on claimed cartridge life span. For certain reverse osmosis units, professional service (PS) is recommended by the manufacturer. The filter cost/yr. for the reverse osmosis units does not include the osmotic membrane which typically lasts at least two years
Filter-life indicator Filter-life indicator shows models with this feature.
I've been very happy with this water filtering carafe. I've used it daily since August 2011 and it works very well. Water tastes very good and I've been traveling in my RV all over the West where the water is often hard.

Very poor design and manufacturing. The water line feeds into a plastic gear assembly to measure the water use. The water then flows into the filter assembly thru a small nipple. Unfortunately, the nipple becomes loose and leaks or the nipple completely separates from the filter assembly. This happened right out of the box. I did notice a spot of glue, that could have been used to attach the gear/nipple assembly to the filter housing....poor design....not made to last...cheap plastic...

Heavy When Full To Top
I was attracted to this pitcher almost entirely because of the data on how effectively the filters remove potential contaminants. I think our water supply is good, but with a pregnancy, we want to be extra careful.<br /><br />During use, I have been really pleased about:<br />* easy attachment of the adapter to our faucet; <br />* easy attachment of the hose to the faucet-adapter when filling;<br />* filling and filtering on its own while I do something else nearby in the kitchen;<br />* quick filling without having to wait the water to gradually drain through like we had to on another kind of pitcher we had for years;<br />* excellent, clean flavor or flavorlessness that has us drinking a lot more water at home and enjoying it more;<br />* longevity of filter cartridges;<br />* having the filter present information on actual water-flow through it, to indicate need for replacement;<br />* simplicity of filter-cartridge replacement, as I just bought a 10-pack of CWF1016 cartridges that should last us for several years.<br /><br />We are less pleased with:<br />* the weight of the pitcher when filled to the brim, which bothers one family member who thinks its too easy to spill when that full, because it's heavy to hold. That doesn't bother me, and we either don't fill it to the top, or I have a cup of water right after filling it.<br /><br />Highly recommended. I have already recommended it to friends.
