DuPont WFPFC8002 Carbon Wrap 2-Phase Cartridge, 2 Count (Pack of 1), Grey, Gray

After struggling with dozens of different whole house filters for over a year in an effort to solve my ferrous/soluble iron problem with no luck, these filters finally did the job and cleared this challenging type of iron from my water saving me from having to buy an expensive extra filtration system! The backstory - A little over a year ago I bought my first home and after examining the water test report I noticed a high iron content in the test, I was assured it was harmless (it is) but having always had city water previously, I didn't really understand any problems it might cause. However, within a month I began to notice my silverware coming out of the dishwasher with rust spots and my drinking water filter unit in the fridge was becoming ringed with yellow iron, not to mention the water tasted metallic and awful. On top of that the toilet, sink and bathtub kept turning yellow with days of cleaning them and some of my clothes started to get spots, very frustrating! I did more research and purchased a second more detailed water test for my home which confirmed I had high levels of ferrous iron. The interesting thing about ferrous iron is that it doesn't appear in freshly poured water at all, it comes out crystal clear, and then oxidizes once exposed to air, hence the discoloring of things later. Looking for solutions, everything I found indicated we'd probably need an advanced double filtration system with a special second filter that would oxidize the iron before it got into the house. Either that or we'd need to add water softener which can also pull iron but causes other problems. Thankfully someone suggested I try carbon water filters first because it solved their iron problem, although I was skeptical because there are many types of iron and mine was among the more challenging to deal with. The first carbon filter I picked up from a local hardware store did absolutely nothing. After two months the same level or iron was appearing on silverware, the tub etc. and the water still tasted bad. So I researched more and found these on Amazon, where several people said it could handle soluble types of iron. They were cheap so I gave them a shot. At first I think there was still some iron in my pipes and despite installing the new filter, I noticed my toilet/tub yellowing after a week and a half so, but I noticed it was not as severe as previously and maybe that was as good as it was going to get. So I cleaned everything again and sort of forget about, thinking I was doomed to spend thousands to fix this. I sort of tuned out after that and stopped paying close attention, but after two more weeks I was looking at my bathroom fixtures and thought "huh, they aren't yellow...wait a minute, they should be yellow by now!" So I refilled my water filter pitcher, tasted the water and it finally tasted normal. It was working! I'm on my third month of using these now and couldn't be happier. No more rust on my silverware ever! No more yellowing sink, toilet or bathtub and I can actually drink my water! The only downside is these are so good at filtering iron they get clogged quickly and thus instead of changing them every 3 months like normal filters, I have to change them every month or two, and you will know when the water pressure drops sharply. When I go downstairs to change them they are caked in rust, so much so that they dye the cellar floor orange where I put them down, but that just means they are doing their job. I'm willing to buy these more often as they are affordable and saved me from having a more complex filtration system/constant need for water softener.

Excellent product

If you're skeptical that these seemingly tiny carbon filters will actually work let me help clear that up. We were experiencing the rotten egg smell in our well-water supplied home and the wife began to "be concerned." Over a period of a few weeks I disinfected the drains to eliminate odor coming from air displaced by running water then proceeded to disinfect the water softener, followed by disinfecting the water heater. Unfortunately the problem would return and was then found to also be coming from the cold water indicating the source was more likely to be our well. The "concern" continued to mount until it was a matter of significant importance. You can skip this paragraph if you have no interest in well disinfection... The chore of well disinfection was next. I first guess-timated an amount of bleach to treat our well and entire house. After everyone showered in the morning I began by bypassing the water softener. I then started running the hose into the well head. I trickled about half a gallon of bleach slowly over a few minutes into the well along with the stream from the hose. After the hose water began to smell like bleach I turned off the hose and poured a bucket of pre-bleached water into the well to remove any residual chlorine from the walls. Next I ran water from the furthest reaches of the house faucets first hot and then cold until the water began to smell of chlorine. I did this for each faucet and then the waiting began. After almost 12 hours the system was near finished treatment. I re-connected the water softener back into the system and ran water through the softener to allow the softener to have some limited exposure to the chlorination. I waited another hour and began the flushing process. First I ran a hose out to the woods (to avoid running chlorine down the septic system drain) and let it run for probably 2 hours. It still smelled like chlorine but not nearly as strong as it did at first. I then drained the water heater entirely and refilled it so we'd have hot water in the morning. I ran each of the faucets until they smelled less like chlorine though at this point I could not be sure how much smell there really was. The next morning I assured everyone they could take showers. Unfortunately the smell was stronger than I thought and the shower was a lot like swimming in a pool. Obviously this did not make everyone happy. I ran more water and thought the smell was improving but again this was after inhaling a good amount of chlorine already. Apparently the smell was still too strong for her liking and thus the problem. With some very noticeable chlorine smell still present in our water system, I installed this unlikely hero into the post-softener filter location. I then ran water through faucets until it seemed there was no chlorine smell at all. I once again emptied the water heater and filled it back up. I ran water at every faucet again and violá! The system was cured! This little filter removed all the chlorine smell from the water and the wife, though not singing my praises, has ceased voicing her "concern."

Very nice. Much less expensive here than at our local supercenters. A helpful hint or two, best not to change in the colder winter months if possible if your cellar is like mine and it's an old drafty farmhouse. More importantly, remember to fill a bucket with warm water before beginning the changing process (shutting off of water) so that you have means to clean the glass insulator part which gets quite nasty if you have well water. Also, if you put a smidgen of petroleum jelly along the seal area it makes it easier to screw the glass part back on for a tight seal so water doesn't spray all over. Yup. It happened. When it was cold, in the drafty farmhouse cellar on a freezing, and I mean wayyyy sub zero freezing Upstate NY winter not-so-nice- day. But we had to have water. Never thought to just run it in by-pass. Silly younger stubborn me. Also, try to keep an extra seal on hand.

Great whole house filters. Filters out extremely small sediment and even helps to improve taste.

We use this filter for the whole house (triplex with one main water line) to help with pressure and as a easy, quick fix to a problem with our water line (expensive to fix). This is working great until we can fix the problem. But we are also seeing the value in keeping like this as it collect a lot of muck from the town's water supply system. Between the 3 apartments, we change the filter once a month. We feel comfortable with it, however, we still would not drink it.

Installed this August 10th. Have used approximately 15k gallons (small kid has a bath everyday plus 2 showers a day for me and the wife). Been 3 weeks of use so far, I changed it because the supply pressure was a bit low during a shower, I'm sure it could have gone a bit longer though. Definitely working as my secondary filter is still clean. Extremely happy with the purchase, I'd like to protect my softener as much as I can, I have this with a DuPont filter casting ahead of the softener and then a 3 stage 20 inch cartridge filter on the outlet for odor. So far, very happy!

El agua sale muy limpia y se eliminó un olor extraño que tenía la misma antes de haber hecho el cambio. Lo instalé en un cartucho o contenedor Rotoplas y aunque quedó bien, tuve que quitar los empaques de arriba y abajo para que quedara bien, además de ponerle cinta de Teflon a la cuerda del contenedor porque no cerraba bien, ya que estos cartuchos son más largos. Fuera de eso, todo bien, aunque probablemente la próxima vez adquiera unos del tamaño adecuado

El producto que me llego no tiene envoltura de carbon activado.

Notorio cambio en el agua de casa.

J'ai récemment acheté ces cartouches de rechange pour mon Filtre à eau Rainfresh CF250 et je suis très satisfaite de mon achat. Elles s'adaptent parfaitement à mon filtre et ont la bonne dimension. Ce que j'aime de ces cartouches en papier plissé c'est qu'ils permettes de filtrer l'eau sans réduire la pression de l'eau.
