Designed for large rooms, open-plan living areas, and bedrooms, this DREO model combines a 3-in-1 filter, a high-precision PM2.5 sensor, and a powerful spiral airflow system to remove particles, dust, pollen, smoke and common household odors. AHAM Verified with a CADR of 158 CFM, the unit is engineered to refresh air quickly while staying energy conscious and whisper-quiet in low settings.

How fast and how much air can this purifier clean?

The DR-HAP009 is AHAM Verified and rated with a Clean Air Delivery Rate (CADR) of 158 CFM, giving you measurable performance. It refreshes air every 12.4 minutes in rooms up to 245 sq ft at 4.8 air changes per hour, and at 1 ACH it covers spaces up to 1,176 sq ft—useful for larger living areas and combined rooms.

• CADR: 158 CFM for particle removal efficiency.
• 245 sq ft coverage at 4.8 ACH (full refresh every ~12.4 minutes).
• Up to 1,176 sq ft coverage calculated at 1 ACH for baseline planning.
• Large 360° spiral intake to speed circulation.

What filtration and sensors are included to capture pollutants?

The purifier uses a 3-in-1 filter assembly—pre-filter, high-efficiency HEPA layer, and an activated carbon layer—to trap PM2.5, pollen, pet dander, smoke and household odors. A high-precision PM2.5 sensor continuously reads particle levels and displays an AQI value on the LED screen with a four-color indicator for quick air quality status.

• 3-in-1 filter: pre-filter, HEPA-style filter, activated carbon.
• Real-time PM2.5 sensor with AQI 0–999 display and RGB indicator.
• Transparent filter viewing window for easy visual checks.
• Auto mode adjusts fan speed based on live sensor data.

How quiet and energy-efficient is the unit for bedroom use?

The DR-HAP009 is built for low-noise operation with an efficient BLDC motor and optimized spiral intake that reduces sound to as low as 18 dB on the quietest setting. It carries ENERGY STAR–level efficiency characteristics and is designed to use about 162 kWh per year, helping keep operating costs moderate during continuous use.

• Lowest sound level: ~18 dB for sleep-friendly operation.
• BLDC motor for efficient, low-noise performance.
• Estimated energy use: ~162 kWh annually for typical operation.
• Sleep mode dims or turns off lights for undisturbed rest.

Which operating modes and controls help match cleaning to daily needs?

Choose Auto, Turbo, Sleep, or Normal modes and four fan speeds to tune the purifier to your situation. Auto mode responds to sensor readings, Turbo provides maximum airflow for fast cleaning, Sleep minimizes noise and display lights, and Normal lets you manually select the fan speed for steady performance.

• Auto mode: automatic speed adjustments based on air quality.
• Turbo mode: peak airflow for rapid particle removal.
• Sleep mode: low noise and lights off for night use.
• Manual control: four fan speeds for daily flexibility.

Who this is for: The DREO DR-HAP009 is a strong fit for households with pets, seasonal allergies, smoke concerns, or larger open-plan spaces that need measurable air exchanges. It suits anyone who wants validated CADR performance, continuous PM2.5 feedback, low-noise overnight use, and a clear view of filter status for easier maintenance.
