Why US31; No more paying to have water delivered, or wasting time replacing low-capacity pitcher filters and faucet filters, the US31 Under-Sink Water Filter provides up to 2000 Gal. directly from your tap at a fraction of the cost. This 3-stage filter system is designed for easy installation, low maintenance, and features a high-capacity sediment filter, a granular activated carbon (GAC) filter, and a carbon filter. The sediment filter protects and extends the life of your system by removing visible particles, while the GAC and carbon filters work together to eliminate harmful contaminants like chlorine, odor, and taste, providing you with bottled-quality water on demand.

The WGB21B is a great "point of entry" filtration system and an excellent alternative to the larger WGB22B for smaller homes. The WGB21B will filter water directly from your source. This means that water from every outlet will have passed through this filter, providing up to 50,000 Gal. of clean water for the entire family. The first stage of this system houses a 5-micron high-capacity polypropylene sediment filter (FP15B). This filter is responsible for removing dirt, rust, and most suspended solids, to protect the CTO carbon block filter. The second stage houses the 5-micron CTO coconut shell carbon block filter (FC15B). Block carbon is more effective than other forms of carbon in that it is finely ground up carbon packed into a solidified block. This means they have a higher density than other types of carbon filters and are therefore more effective in removing their targeted contaminants. The carbon block filter knocks out bad tastes and odors, removes over 90% of sediment and chlorine, and is highly effective on chemicals, like pesticides, herbicides, and industrial chemicals.

Item is very reasonable for pricings... it just took way too long for delivery. Minh T. Thu Jul 02 2026

Experience the convenience of the cold and hot RO water filter system with the iSpring RCD100HCG. Featuring thermoelectric cooling technology, this alkaline reverse osmosis system operates quietly and delivers cold water efficiently while consuming less power and space compared to traditional compressor cooling systems. Designed with 9 temperature options and 6 dispensing volume options, it can be easily adjusted to meet different hydration preferences.

My parents got me this system as a housewarming gift and it’s been great! The tap water right now tastes like lakewater due to the algae bloom in the local reservoir, but this machine makes it taste great again and quickly dispenses hot water for ramen and tea. Setup was as easy as finding a spot on the countertop, filling the water tank, and plugging it in. The instructions are clear, and there are a ton of options for how much water to dispense at a time and water temp (including a formula temp for mixing baby formula). I’ve replaced my zojirushi water boiler with this since the hot water function is integrated and so fast. The only thing I wish I could change is to make the dispenser height a little higher so that my sodastream bottles fit underneath. Right now it’s just a quarter inch short so I need to pour the water directly from the pitcher into the sodastream bottle (first world problems, I know). Overall, it’s been great and made me want to drink plain water again!. Amanda. Atlanta. Sat Dec 13 2025
