Pattern Name: Water Filtration System


Features

  • Enjoy Clean Water from Every Faucet: WCFM400K is an efficient and economical whole house central filtration system to reduce dissolved iron and manganese compounds from raw water supplies. Reduces iron, manganese, solids, and turbidity with sediment filtration. With an automatic media regeneration feature and digital control valve, the system is maintenance-free after setup.
  • Use No Chemicals: With new technology, WCFM400K whole house water filtration system uses only air for media regeneration. The filter media is certified to NSF/ANSI Standard 61. Unlike similar systems from other manufactures, iSpring WCFM400K uses no oxidizers or chemical feed other than the same air we breathe.
  • "Set & Forget'': Simple to install and easy to set up. Customizable auto-flush intervals depending on your incoming water quality and usage, saving you time and money in the long run. It is indeed a silent guard at the point of entry for your entire house with well or city water. Note that this system DOES NOT remove hydrogen sulfide(H2S) and would cause system damage if the water contains hydrogen sulfide(H2S). Please consider our WCFM500K for removing hydrogen sulfide(H2S) in water.
  • Peace of Mind Customer Service: Besides a 30-day money-back guarantee, iSpring stands behind its products by providing a 1-year manufacturer warranty and lifetime free technical support. Extended warranty plans are also available upon registration online. Local customers are welcome to visit us and pick up products at our warehouse in Cumming, GA.
  • Please Note: Unlike an RO system, this system will NOT reduce Total Dissolved Solids (TDS). If you are interested in removing TDS, please consider our iSpring Reverse Osmosis (RO) systems for additional protection.

Description

Enjoy clean water from every faucet at home. iSpring WCFM400K removes iron and manganese from your water efficiently and effectively. The system uses air injection with advanced catalytic media to remove iron and manganese from the water. During the backwash process, the system introduces fresh air into the top of the tank. As the water passes through the pocket, it is infused with the oxygen in the fresh air, and the advanced catalytic media is a catalyst between the iron, manganese, and the air. The oxidation process is almost instantaneous; the iron and manganese precipitate and are trapped by the media bed. The system's electronic control valve automatically backwashes the system to clean the filter media and flush the precipitated iron and manganese down to the drain.

our local water company started dumping more chemicals into our water and the quality was poor. seemed we were using more soaps, water and ice tasted funny and definitely too much chlorine. The water was harsh on our skin and hair so we started looking into alternatives. The installation was a breeze, our plumber had us up and running in a few hours. The Ispring product has removed the taste of chemicals and we were able to cut way back on soaps, now using less than half of soaps, shampoo and conditioners which will save us a little money in the long run. My hair is back to normal and not breaking off, skin is also returning to normal, not scaley or flakey. Calcium no longer building up like it was. We highly recommend this product to anyone, they more than met our expectations and stand behind thier procucts!! Nick was outstanding to work with, answered all our questions, out a of five star review, they deserve a 10 ! ... show more

    • This filter system works great and is reasonably easy to install.
Style: Iron Manganese H2S Pattern Name: Water Filtration System
Update, installed Jan 2023. Now is July 2023, system is still giving us great water and no stains at all. Still happy with our ISpring system. Our house is connected to a well that is measuring 5ppm on the iron test and the water will stain our fixtures within about 3 to 4 days of normal use. When we first built here our well tested in the 1 to 2 ppm iron content but has increased to 5ppm over the years. I now use iSpring FP150 50 micron filter in filter position 1 to catch the big stuff and then have the WCFM500K as filter position 2 to remove the iron and manganese and then have the FC25b 20”x4.5” CTO carbon filter in filter position 3 to polish off other impurities before entering the house. At the kitchen sink I have added the iSpring RO800G tankless reverse osmosis system to have good, clean cooking and drinking water. I installed all of this myself and really glad I have chosen the tankless system to use under the kitchen sink. It was very easy to connect and it takes about the same amount of room as a regular computer tower. I will post before and after water test results at a later date but this system has been in use now for about ten days and we now have NO red stains at all and iron measures 0 ppm now and the water tastes absolutely better that any water I have ever had. I have friends and neighbors that have other types and brands of water systems on the homes but after about 6 months of research of all of the brands and ways to correct my water issues I chose to go with iSpring because of the quality and reputation. I did narrow my choices down to three different companies and at that point I called each company to get a feel on the quality of help available. That test showed without a doubt that iSpring would be the best company to deal with. I did talk to Don a couple of times and he was quick to answer the questions I had before and after purchasing my setup. ... show more

    • Very nice unit, exactly what I needed!

I read about a few whole house water filter systems and settled on this one. I'm glad I did, because it is now over 4 months old and no issues at all. We had nasty tasting city water and even discoloration in the water when the city would be working on it sometimes. This system has taken care of all of that perfectly. Excellent tasting water. We were buying bottled water in the drinking size, as well as big bottles every week. This unit will pay for itself in 3 years based on what water was costing us. The unit should last about 10 years, at which time I'll likely buy another one. No filters to change ever, and simple installation. I also have a lead entrance pipe, and although not the best system for that, it does reduce it. Highly recommend this unit. The I-Spring folks even followed up with me twice after the purchase, on their own, to see if I had any questions, even though it was purchased through Amazon. GEG ... show more

We just moved to a new house earlier this year. Using water from a well, the water quality was really bad, so we decided to buy a whole house water filtration system. With some research and inquiry, we found this iSpring WCFM400K. Their customer service is really impressive and patient, suggesting us to test our water quality first and recommending this system, which is great! The installation process is really easy. We didn't spend much time setting up it. There's something you need to pay attention to during installation. The system inlet and outlet connectors are 1 inch. The pipes in our home are 3/4 inch, so we had converted the fitting down to 3/4 inch. The auto-flush intervals function is convenient. It's easy to set up and works well. We don't need to be concerned about changing filters or maintenance. The water quality has improved a lot. I can clearly feel that the strange smell disappears and the water becomes much fresher. So far, the system works pretty well and my family is satisfied with it. ... show more

    • Buy this if you want your entire home to smell like rotten eggs
Style: Iron Manganese H2S Pattern Name: Water Filtration System
We had this base 3 filter product (WGB32BM) professionally installed to remove the iron from our water at the guidance of iSpring representatives. This did not work, the iron filter was brown and useless in 30 days. Was then told that because our Iron PPM was over 2 ppm (which is all this system can handle) that we needed to install their $2000.00 WCFM500K filter which would remove up to 12 ppm (we have 6 ppm). We had this professionally installed inline with the original triple filter set. Two months later, every room in the house with a cold water tap smells like rotten eggs (sulfur) each time you turn on the faucet. IT'S AWFUL. Our plumber isolated it to the iSpring products and says its likely gasses being released from bacteria in the filters. So now we have spent almost $4000.00 on iSpring products and plumbing installation charges and we're unable to drink our water or have company over because of the horrible odor. I have no idea if these gasses are harming my family on top of all this. It's very possible they are toxic. When iSpring finally got back to us (after multiple calls spanning a week), they are attempting to figure out what to do about this but don't know yet. I am giving this product 1 star until they resolve this issue. I will update this review if we're eventually able to achieve properly filtered water in our house. ... show more
