Frizzlife FK99 Under Sink Water Filter System | NSF/ANSI 42 & 53 Certified, 0.5-Micron Filtration

Cleaner, fresher water from your tap

The Frizzlife FK99 under-sink water filter system sits discreetly beneath your kitchen counter and connects directly to your existing faucet. Its compact design keeps the sink area tidy while delivering a steady flow of filtered water for drinking, cooking, and beverages.

Smart filtration you can count on

At the heart of the FK99 is a 0.5-micron block filter built with NSF/ANSI 42 and 53 certified filtration media and coconut carbon. This combination is designed to reduce chlorine, bad taste, and odors while preserving minerals that matter for everyday use. The result is water that tastes cleaner and drinks crisper, without guesswork.

• Direct connect to your kitchen faucet with no extra faucet needed
• Cold water only, ideal for home kitchens, offices, and small spaces

Built to last, with thoughtful details

Durability is built in: the FK99 uses lead-free brass fittings and a robust housing. It has passed extensive pressure testing and features an auto-shutoff valve so you can swap the inner cartridge without shutting off the main supply — clean and simple maintenance.

Long-lasting performance, less waste

The inner filter has a high capacity, with an estimated filtration of up to 10,000 gallons or about 12 months of use, depending on water quality. When it is time to replace, you only swap the inner cartridge, not the whole housing, reducing waste and cost. Typical flow is 2 GPM at 60 psi.

• Eco-friendly maintenance with cartridge-only replacements
• Consistent flow and reliable filtration over time

Versatile placement and easy setup

Perfect for kitchens, offices, bathrooms, and even recreational vehicles. The FK99 can serve both your sink and refrigerator by using the IMC-2 ice maker connection kit. It is backed by dedicated 24/7 customer support and an 18-month warranty window.

Simple DIY installation

Setup is designed to be quick and straightforward: about five minutes with standard 3/8 NPT or 1/2 fittings. Threaded copper connections minimize leaks, and the system offers a compact footprint to keep your counter neat.
