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.
