The iSpring CKC1C-PB/CKC1-PB countertop water filter is a compact yet effective solution for improving the taste and safety of your tap water. It features a high-performance filter cartridge made with advanced MetSorb media, which efficiently reduces heavy metals like lead, arsenic (III & V), mercury, and cadmium. This filtration media is tested by SGS, offering reliable protection while helping to retain healthy minerals. Designed for convenience, this countertop water filter connects directly to most kitchen sink faucets in minutes—no tools or permanent installation required. Its BPA-free, food-grade construction ensures safe daily use, and the system delivers consistent performance for up to 12 months or 7,000 gallons, depending on water conditions. Ideal for apartments, rentals, and small kitchens, CKC1C-PB/CKC1-PB drinking water filter provides a space-saving, budget-friendly alternative to under-sink systems without sacrificing performance. For reduction of Total Dissolved Solids (TDS), pair this unit with an iSpring Reverse Osmosis system such as the RO500 or RCT600 for complete purification at the point of use.

The WGB22B whole house filtration system is an ideal "point of entry" filtration system for cleaning up water supplies to a home or business on municipal (city) water. Unlike "point of use" systems (like reverse osmosis systems) that are installed to supply water to a specific faucet, the WGB22B filters your water from the source. This means water from every output in your home will have passed through the two filtration stages of the WGB22B. The stage 1 housing holds a 5-micron high-capacity polypropylene sediment filter. This filter removes dirt and other various larger sized particles from the water that can clog the following filter. The second stage of the WGB22B houses a CTO coconut shell carbon block filter. 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 up to 90% of chlorine from the water, and is highly effective on chemicals like pesticides, herbicides, and industrial chemicals.

Made from food-grade BPA-free materials, the system is durable and leak-resistant, offering a continuous supply of clean water for 6-12 months, depending on water quality. Perfect for homes, rental properties, and RVs, its sleek countertop design adds both style and functionality to any kitchen. Please note, it retains healthy minerals while removing harmful chemicals but does not reduce Total Dissolved Solids (TDS).

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.

Looks like it should work well. Bought it to put on our 5th wheel but winter is here and camper is winterized. I will put it on in the spring. Can’t wait!!!!. Craig. US. Thu Nov 13 2025
