The ECOSELF HAP604 is a powerful whole-room air purifier with a 3-stage H13 HEPA filter and 360° airflow that cleans spaces up to 1500 ft² while running as quietly as 20dB.

If you need steady, reliable air cleaning for a bedroom, living area, office, or pet space, this model combines wide-area coverage with energy-efficient performance and easy user controls. Its compact design, brushless motor, and certified filter system focus on removing pollen, dust, pet dander, smoke and common household odors without drawing attention or power.

How fast and how large an area will it purify?

The ECOSELF HAP604 uses 360° intake and a directed outlet to maximize circulation, moving and filtering the air in large rooms quickly. CADR-equivalent performance reaches up to a 1500 ft² exchange per hour under typical conditions, making it suitable for open-plan spaces.

• 360° air intake for consistent whole-room coverage
• Designed to refresh up to 1500 square feet per hour
• Streamlined outlet reduces turbulence and boosts airflow

What does the filtration system remove and how reliable is it?

Filtration is handled by a 3-stage setup topped by an H13 True HEPA layer that captures particles down to 0.3μm with high efficiency. Together with pre- and activated-carbon stages, it tackles particulates, odors and airborne irritants for clearer indoor air.

• H13 True HEPA captures up to 99.97% of fine particles (0.3μm)
• Pre-filter prolongs HEPA life by catching larger debris
• Activated carbon layer helps reduce smoke and household odors

Will it disturb sleep or raise energy bills?

No — the unit features an ultra-quiet sleep mode that lowers noise to about 20dB so it runs unobtrusively at night. Its brushless motor also improves efficiency, keeping typical daily power draw low for long-term, economical use.

• Sleep mode: as quiet as ~20dB for night use
• Brushless motor increases efficiency and lowers noise
• Estimated power around 0.35 kWh per day in normal operation

How do I control and maintain the ECOSELF HAP604?

Controls are straightforward with four fan speeds, a 2/4/6/8-hour timer, ambient light options, child lock and a filter life indicator to simplify upkeep. ECOSELF genuine replacement filters are recommended to preserve performance and ensure a proper fit.

• 4 fan speeds and multi-hour timer settings for flexible operation
• 7-color ambient light with an off option for undisturbed sleep
• Filter indicator, child lock and simple filter-replacement process

Who is this for? The ECOSELF HAP604 suits families, pet owners, and anyone who wants effective, low-noise air cleaning across large rooms. It’s intended for people seeking a balance of coverage, filtration efficiency, quiet overnight operation, and straightforward maintenance with certified components and responsive support.
