1. Introduction
Thank you for choosing ALTHY products. The ALTHY U200PRO under-counter water purifier is designed to provide safe and healthy drinking water for your family. It utilizes a Nano antibacterial carbon rod filter element, enhanced with patented MetSorb® Adsorbent Media, certified by NSF. This system effectively filters sediment, rust, residual chlorine, and heavy metals like cadmium, lead, chromium, and arsenic, with a removal rate of over 90%.
Note: The AL-U200Pro will not reduce the TDS value (ppm) of water. TDS value is not the sole basis for judging water quality.
Figure 1: U200PRO's Nano Integrated Composite Technology combines 5 filtration stages (PPF, ACF, AGF, KDF, MetSorb®) into one compact unit, replacing traditional multi-filter systems.
Figure 2: MetSorb® Adsorbent Media, certified to NSF Standard 42, efficiently removes heavy metals like arsenic, lead, and mercury from drinking water. Note: Does not reduce TDS.
Figure 3: NSF 42 & 53 Certified Filtration Elements remove 99.99% of contaminants including rust, fluoride, lead, sand, bacteria, chlorine, odor, and insects, while keeping beneficial minerals.

4. Installation
The ALTHY U200PRO provides a flexible and convenient water supply. The recommended installation method is under the sink.
Installation Steps:
- Select Location: Choose a suitable installation location under your sink. Ensure a floor drain is nearby.
- Connect Water Purifier: Connect the water purifier to your household tap water point.
- When installing pipe joints, wrap joints without gaskets with a suitable number of turns of raw material tape (Teflon tape) to ensure a leak-proof seal.
- Turn the filter bottle counter-clockwise to remove the filter element (this is for initial inspection or if you need to pre-flush the system without the filter).
- Initial Flush: Open the three-way valve, turn on the water purifier faucet, and flush water for at least 10 minutes until the water runs clear.
- Final Flush: After complete installation, turn on the faucet and flush with water for at least 5 minutes until the water becomes clear. The system is then ready for normal use.

Filter Replacement Method:
- Shut Off Water: Close the three-way valve.
- Drain System: Open the water purifier faucet to drain any remaining water from the machine.
- Remove Old Filter: Unscrew the filter bottle counter-clockwise by hand. Then, unscrew and remove the old filter element.
- Install New Filter: Tear off the protective film from the new filter element. Screw the new filter element into the base. Place it back into the filter bottle and tighten the filter bottle clockwise by hand.
- Flush System: After installing the new filter, turn on the faucet and flush with water for at least 5 minutes until the water becomes clear.
5. Operation
Once installed and flushed, the ALTHY U200PRO is ready for use. Simply turn on the dedicated water purifier faucet to dispense filtered drinking water. The system provides a flow rate of 3 liters per minute, ensuring you don't have to wait for your water.
