RO-5A Under-Sink RO Water Purifier

RO-5A Under-Sink RO Water Purifier

The Qiteng RO-5A Under-Sink RO Water Purifier adopts 5-stage reverse osmosis filtration and is hidden beneath the kitchen sink, saving valuable countertop space. Equipped with a 3.2G pressure tank for on-demand drinking, a smart panel displays TDS water quality and filter status in real time, with auto-flush to extend RO membrane life. Designed for regions with hard water, heavy metals or high TDS (e.g. South Asia, the Middle East and Southeast Asia), the output meets direct-drinking standards.

Key Features

  • 🛡️ 5-Stage RO Filtration — Removes 99.9% of heavy metals, bacteria and scale.
  • 🪣 Pressure Tank Storage — 3.2G large capacity for uninterrupted supply during peak usage.
  • 🧼 Auto-Flush — Extends RO membrane life and lowers maintenance cost.
  • 🏠 Under-Sink Hidden — No countertop occupation; a cleaner, tidier kitchen.

Core Functions

① 5-Stage RO Deep Purification

PP Cotton → UDF Granular Carbon → CTO Compressed Carbon → RO Membrane → T33 Post Carbon. 0.0001 micron precision effectively removes rust, chlorine, heavy metals (lead / arsenic / cadmium), scale, bacteria and viruses. [Confirm actual filter combination]

② Smart Digital Display

The panel shows TDS water quality and working status in real time. A 4-button design — filter replacement / water test / safety protection / standby — is intuitive and easy to use even for the elderly.

③ Pressure Tank Storage System

Standard 3.2G (~12L) pressure tank: ready to use when full, so multiple taps running at once are never a problem. Low drain ratio (1:1) saves more water.

④ Black-Gold Appearance · Under-Sink Hidden

Black body with gold ripple decoration for a premium feel; compact footprint allows wall-mount or free-standing placement, hidden under the sink with zero countertop occupation.

FAQ

Is installation complicated? Do I need a professional?
Standard fittings are included for DIY wall-mount; we recommend a local plumber or our video guide — about 30 minutes.
What is the pressure tank for?
It stores pure water so supply is uninterrupted during peak usage or when multiple taps are open, improving the experience.
How often should filters be replaced?
Depends on water quality: PP / carbon about 6–12 months, RO membrane about 24 months; the panel reminds you.
Can it handle high TDS / hard water?
The RO membrane is designed for high TDS and heavy metals; proven effective in Middle East and South Asia field tests.
