I bought these for my WaterDrop faucet filter and they last a long time, do the job and are really good value for money. I'm ordering more now but the last ones I bought was 2018 and I only have to change them every 3-4 months which makes them great value for me. If I need to replace them and I really look like they spilled dirty water and I have city water, that doesn't sound very good for me to need to buy city water, does it? I really like them and am buying more for my filter as I just used my last one and want to have them on hand for my next change. UPDATE: This is my fourth time reordering these filters. The faucet filter still works fine and the filters need to be changed about every three months when our city water isn't too cloudy. So I only change them when needed and it saves me more money but also helps us filter our water. I have to filter our water before we put it through the Berkey water filter, the filters in Berkey clog too quickly and I have to backwash too often. So I also use these filters. Saves us money, our stomachs and our bodies from the nasty chemicals that leach into our water from the source, the CITY. I have had other filters but this seems to be the best for us and I love the fact that it lasts longer than other brands.
