We live in a water district that gets it's water from a series of wells. It's mostly acceptable water, but every once and a while we would see a noticeable color change in the water for a day or two - a yellowish tint. The water district said there was no issue, but we were concerned what quality of water we were actually getting. We also have an on demand hot water heater. They are more prone to develop scale from poor water supply. The filter system installation was straightforward and easy. It is bigger than you might imagine, so measure to make sure that you'll have the wall space required. We immediately noticed a difference in our water quality. The clarity of the water in our bath was noticeable. It almost felt like we had installed a water softener. The replacement filters are easy to replace. Watch for them on sale to save yourself a few dollars. High quality and a noticeable difference! Review: Outstanding Product and Exceptional Support! - I am absolutely thrilled with both the iSpring product and the outstanding customer support provided by Francis! After installing it by myself, I encountered a minor leak. Despite my best efforts, there was a slight water leak in three separate places. #1 is fixed with a slight tightening, but #2 (the other side) and #3 did not stop. I reached out to iSpring's support, and Francis stepped in to assist me. His response was not only prompt but incredibly detailed and helpful. Following his instructions, I applied O-ring grease, which stopped the leak at #3. Although it didn't completely stop the leak at #2, it did help reduce it. That is when Francis quickly arranged for replacement parts to be sent to me. He provided a tracking number and kept me updated throughout the process. The replacement arrived swiftly, and I am happy to report that the system is now working perfectly. The leak has been resolved, and the system is performing flawlessly. Whenever we experience heavy rain or a series of rainy days, the water in our city often turns brown for several hours, sometimes even longer. During these times, the city sends out water quality warning text messages. Residents in our subdivision are advised to flush their taps until the water runs clear again, as recommended by the city. After installing the iSpring filter, we had three days of rain, yet the water inside our house remained clear. However, the water in our garden, which is not filtered through the iSpring system, was as brown as usual. The product itself is top-notch, and Francis’s support was the cherry on top. His dedication to resolving my issue and his detailed instructions made a potentially stressful situation smooth and straightforward. Thank you iSpring and Francis for both their excellent products and their exceptional customer service. ## Features - [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.

Many users can complete installation on their own, but a plumber’s assistance can make the process even easier and quicker. **Q: Is there anything special I should know when installing this system?** A: For best results, apply plumber’s tape and tighten the fittings evenly during installation. This ensures a secure setup and helps prevent seepage, allowing the system to perform reliably. **Q: How long does the housing usually last?** A: Made with high-strength materials, the housing is built for long-term use under normal water pressure. Adding a pressure regulator can further extend its service life. **Q: Can I install this system outdoors?** A: Install indoors in a well-ventilated area, shielded from wind and rain, and away from direct sunlight and heat. For outdoor installation, ensure insulation against frost and sun, and waterproofing for both the unit and the pipes. **Q: Does this system remove TDS?** A: The System is designed to reduce sediment, chlorine, and certain chemicals, effectively improving water quality and taste. It does not reduce TDS. If lowering TDS is your goal, we recommend pairing it with an iSpring RO system. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Highly Recommended if You Have a Questionable Water Supply *by D***N on January 3, 2026* Like most people, we purchased this to clean up our local water.

The install went good. Make sure to follow instructions about the thread tape around if wraps. There is a couple of plastic guides that are on the filter housing. I thought they had to be removed before installing filters. I found out they are there to line up filters. Very happy with performance. ## Frequently Bought Together - iSpring WGB21B 2-Stage Whole House Water Filtration System, with 10" x 4.5" Sediment CTO(Chlorine, Taste, and Odor) Filter, 1" Inlet/Outlet - iSpring F2WGB21B Whole House 4.5"x10" Water Filtration High Capacity Sediment and CTO Carbon Block Water Filter Replacement Cartridge Pack Set, Model: WGB21B - iSpring FP15B Sediment Filter Replacement Cartridge for Whole House Water Filtration Systems, High Capacity 5-Micron Premium PP, 4.5" x 10", White --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/32226054-ispring-wgb21b-2-stage-whole-house-water-filtration-system-10](https://www.desertcart.vn/products/32226054-ispring-wgb21b-2-stage-whole-house-water-filtration-system-10) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-04-25*
