Question: Approximately for how long will one cartridge last for two people ?The filtered water would be used for drinking and cooking.Thanks.
Document: This is the second time I am forced to return this item as this filter does not work. Even after 5 days of use, the filtered water is still off-white in color and not crystal clear as one would expect.Don't buy ! !
love these filters, fit tightly in the faucet mount. which is ok because now I can have filtered clean water from my tap. the fact that there were three in package was perfect because now I can use filtered water from my tap for cooking as well as drinking
I like these filters. They work for a long time. I've used other faucet mounted filters and they have only lasted a few weeks each. The DuPont filters will last months without having to change them o experiencing just a trickle of water.
I have used these for years. They last months and work very well. I would recommend them to anyone wanting good water at the twist of a knob.
I used to be able to purchase these at my local Walmart. Nowadays, they do not seem to maintain stock. I did not want to go back to Brita or Pur brand products since they do not last as long as the DuPont line. The DuPont line of filters last a long time before having to replace.
Convenient and great tasting water @ a great value.It would be 5 stars if the value was even greater; perhaps 5 dollars per cartridge.
This filter is rated the best on numerous consumer websites. Have used two other makes and I really like the DuPont. It has done an excellent job here and the Hamilton, Alabama water definitely needs a little more filtration.
I have been using these filters for almost eight years now and there is a big difference using one vs. regular tap water. Great buy for the three pack and is much more economical from the 100 gallon filters I am used to purchasing.
filters as described, filters out bad taste in water, and contaminants, filters last all the way to 200 gallons.unlike pur filters. (water being filterd is city water not well water). would recommend
These are the 200 gallon version filters. They last a long time and are reasonably priced. We are very pleased with them.
Answer: yes
