Experience cleaner air wherever you rest or work

The Cobectal ZQA-4000B air purifier combines a compact footprint with a potent filtration system. Its 360-degree air intake, three-layer filtration (pre-filter, H14 true HEPA, and activated carbon), and coverage up to 1050 ft² offer a balanced approach to reduce dust and odors in shared spaces.

Powerful filtration for larger spaces

Designed for bedrooms, living rooms, offices, dorms, or small apartments, this purifier draws air from all directions. The H14-grade filtration captures fine particles, while the activated carbon layer helps reduce common smells from cooking, pets, or smoke.

• 360° air inlet with comprehensive particle capture
• Three-layer filtration for layered air cleaning
• Effective coverage up to 1050 ft² for expansive rooms

Designed for daily life

Enhance your routine with aroma and sleep features. Add essential oils to the aroma tray to gently scent your space, while Sleep Mode runs quietly with the display off for uninterrupted rest. The LED touch panel makes mode selection straightforward.

• Aroma function lets you enjoy a subtle fragrance during use
• Sleep Mode minimizes noise and dim lights for nighttime use
• Three timer options (2H/4H/8H) help tailor energy use

Practical safety and care

Family-friendly design includes a child lock and a filter reminder to help you maintain performance. Regular filter changes every 3–6 months support ongoing effectiveness and air freshness.

Portability and style round out the package, making this purifier suitable for home, office, dorm, or even RVs. If you have questions, Cobectal support typically replies within 12 hours.
