Under Sink 5-in-1 Stainless Steel Drinking Water Filter

Under-Sink 5-in-1 Filtration for Clean, Great-Tasting Water

Enjoy a dedicated source of cleaner, better-tasting water directly from your kitchen sink. This under-sink 5-in-1 drinking water filter system installs on the cold-water line and delivers filtered water through its own included faucet, so you can use it for drinking, cooking, and food preparation without affecting your main tap.

The system uses a multi-layer filter cartridge designed for municipal tap water. Its five-stage configuration combines PPF, KDF, high-quality activated carbon fiber (ACF), silver-ion antibacterial activated carbon (AGF), and MetSorb media for targeted reduction of chlorine, lead, fluoride, heavy metals, VOCs, odors, and other common tap-water contaminants. At the same time, it is engineered to retain naturally occurring minerals, so the water remains fresh-tasting without being stripped of beneficial elements. Note: this system does not reduce TDS; TDS is not a direct indicator of water safety or cleanliness.

The housing is constructed from 304 food‑grade stainless steel, offering high resistance to corrosion, impacts, and pressure fluctuations. All materials are BPA-free and designed for contact with drinking water. The stainless steel body is intended for long-term use; only the internal filter cartridge needs replacement, which helps reduce plastic waste over time.

Installation is designed as a straightforward DIY process. Included accessories typically comprise a tee or triangular valve, PE tubing, and a direct connection adapter to connect the filter to the main cold-water line under the sink. The dedicated faucet mounts on the sink or worktop (hole required) to dispense filtered water. With the aid of a step-by-step manual and reference video, most users can complete installation in minutes without special tools. Filter replacement is also quick: the cartridge is designed to be changed in about one minute. Under normal household use with municipal tap water, each cartridge can provide up to approximately 6-12 months or around 8,000 gallons of filtered water, depending on local water quality and usage. Replacement cartridges are available under the model name "ALTHY U200PRO".

FAQ

Q: Does this system reduce TDS?
A: No. The filter is designed to reduce specific contaminants (such as chlorine, lead, and certain heavy metals) while keeping beneficial minerals in the water. Because minerals remain, the TDS value often stays similar. TDS is not a direct measure of water quality.

Q: What type of water is this system designed for?
A: It is intended for use with treated municipal tap water. It is not designed for untreated well water, river water, or microbiologically unsafe sources unless the water is properly disinfected before filtration.

Q: How often do I need to replace the filter cartridge?
A: Under typical household use and municipal water conditions, the cartridge usually lasts about 6-12 months or up to around 8,000 gallons. Actual life will vary with water quality and consumption. If flow rate drops noticeably or taste/odor changes, replace the filter sooner.

Q: Is installation suitable for renters?
A: Yes, in many cases. The system connects to the cold-water line under the sink using the provided fittings and uses its own faucet. As long as you are allowed to mount a small faucet hole (or use an existing spare hole), the system can often be removed later with minimal trace.

Q: What should I do before first use?
A: Remove the protective film from each filter cartridge, install according to the manual, and flush the system as instructed (usually several minutes of running water) before drinking. Always check local installation guidelines and ensure all connections are secure and leak-free.
