About this item

  • [Two-Stage Effective Filtration] The whole house water filter has 1st-Stage premium 5-micron polypropylene sediment filter (FP15B) captures dirt, sand, silt, dust, rust, and scale particles, using high quality coconut shell carbon and highly compact fabrication tech, 2nd-stage CTO filter(FC15B) knocks out cloudiness as well as bad tastes and odors, removes over 90% of chlorine, and is highly effective on VOCs like pesticides, herbicides, and industrial solvents.
  • [Superb Filtration Capacity] 10"x4. 5" replaceable whole house water filters can provide up to a full year of clean water(up to 50, 000 gallons) for a family of four. 1-inch inlet and outlet ports allow fast water flow with less pressure loss. Fine PP sediment filter and premium quality CTO filter not only bring clean and fresh water to every faucet in your house, but also help prolong the lives of your water-using appliances and protect plumbing from sediment and scale buildup.
  • [Easy Installation and Filter Change] The system comes pre-assembled onto the mounting bracket for a streamlined, DIY installation. Filter wrench included to make routine filter changes easy and quick. A pressure release valve allows for the release of built-up pressure when changing filters. Refer to our manual and/or YouTube videos to Install this point-of-entry (POE) filtration system at the main water supply to get clean and healthy water for the entire family.
  • [Retain Valuable Minerals] Unlike an RO system, this system will NOT reduce Total Dissolved Solids (TDS), and instead keeps healthy minerals in your water. If you are interested in a filter that removes TDS, consider our iSpring Reverse Osmosis (RO) systems.
  • [Peace-of Mind Customer Service] Backed by a 30-day money-back guarantee, 1-year warranty, and extended manufacturer warranty upon warranty registration at iSpring. Lifetime CS and tech support from Atlanta, GA USA. We stand behind our products. If you encounter any problems with any of our products, please reach out to us immediately. We are happy to help!

5 Stars
Make sure to Teflon tape your fittings 12-15 times!
I setup this whole house filter and only did a 6-7 wraps of Teflon tape and the fittings were leaking after installing which really sucked because I had fluxed and soldered everything together.I called ispring support and talked with Sean. He sent me out a whole new housing for free and stressed the Importance of the number of wraps. I slapped this new one in and everything works as it should.This is a great company willing to support their customers.

Installation was a breeze. The only pitfall was my choice of install location. Limited room in a crawlspace. Components are very solid. The use of "push to connect brass plumbing fitting" made the install even better.

Online New Product Registration was a bit awkward having to file a "ticket", but Laurence from Customer Support was a big help! I did have a leak (a drip) but again, Customer Support was very willing to help. Thanks Nick! Overall, I am very happy with my WGB21B purchase.

Reviewed in Canada on January 2, 2024
Sorting out water filter issues can be challenging. We found our ISpring water filters to be extremely well built and very easy to install.
The big thing, though, is the terrific product support from Ispring!
It can take more than just good filters to get good water, it can be a daunting process sorting out which filters are needed and getting everything you need.
Sean at ISpring was amazing. He spent a ton of time and effort with us helping us figure out what we needed and getting the right filters selected and installed.
We installed a Carbon/Iron Manganese filter set with a sediment spin down filter. They were all very easy to install, didn't leak, are built like tanks and very easy to maintain.
Couldn't recommend Ispring and Sean more.
