Product review (1 stars): This must be Pur's el-cheapo model
This is the second PUR PBSS Push-button filter I've purchase thru Amazon. When I took the first one out of the package my first thought was that this filter was much lighter in weight than the PUR Kenmore 9030 filter I normally purchase from WaterFiltersFast.com.  The PUR 9030 always lasted 3 to 4 months. The first PUR Push-button I purchased lasted only 2 months.  Now this second one is hardly 1 1/2 months in use and we're already tasting chemicals and clorine in our drinking water.  Now I know why the weight of the PUR Push-button was so light...there's evidently very little filtering materials inside.  I guess the old saying, "You get what you pay for" is still correct.  I saved $5 per filter plus free shipping on Amazon for the PUR Push-botton, and even with that savings did not get my money's worth.  I've just ordered a PUR 9030 from WaterFiltersFast.com for $5 more plus $5 shipping....and feel it was worth every penny of the difference to get a filter that will filter more than 1 to 2 months.
