Whirlpool WPPRO2000B Whispure Air Purifier (Slate Black)

How often do I need to replace the filters?

The pre-filter should be replaced every 3 months, whilst the HEPA filter typically lasts 12 months with normal use. The activated carbon filter also needs replacing annually. Filter status lights on the unit will illuminate when replacement is needed, so you don't have to guess. Heavy use or particularly dusty environments may require more frequent changes.

What room size does this air purifier effectively cover?

This unit is designed for rooms up to 500 square feet (46 square metres). The 328 CFM CADR rating means it can clean the air in a 500 sq ft room approximately 4.9 times per hour, which exceeds the recommended 4 air changes per hour for optimal air quality. For smaller rooms, it will clean the air even more frequently.

How loud is the Whirlpool WPPRO2000B during operation?

On low and medium settings, the unit operates very quietly with minimal noise. Sleep mode is specifically designed for nighttime use with whisper-quiet operation. High and turbo modes are noticeably louder due to increased airflow, but the sound is more like rushing air rather than mechanical noise. Most users find even the higher settings acceptable for daytime use.

Does this air purifier produce ozone?

No, this unit is 100% ozone-free and AHAM certified. Unlike some air purifiers that use UV lights or ionisers, the WPPRO2000B relies solely on mechanical filtration. This means it doesn't produce any trace amounts of ozone, which can be a harmful air pollutant. It's safe for continuous use around children, pets and people with respiratory sensitivities.

Can I use this air purifier continuously?

Yes, this unit is designed for continuous operation. The Energy Star certification means it's efficient enough to run 24/7 without excessive electricity costs. Auto mode adjusts fan speed based on air quality, so it only works harder when needed. The sleep mode feature makes it perfect for overnight use without disturbing your rest.

How does the auto mode work?

Auto mode uses built-in air quality sensors to monitor your indoor environment continuously. When the sensors detect elevated contaminant levels, the fan speed automatically increases to clean the air more rapidly. Once air quality improves, it returns to a lower, quieter setting. This ensures optimal air quality whilst minimising noise and energy consumption.

What types of particles does the HEPA filter remove?

The TRUE HEPA filter removes 99.97% of particles 0.3 microns and larger, including dust mites, pollen, mould spores, pet dander, smoke particles and bacteria. It also filters PM 2.5 air pollution particles. The activated carbon filter handles odours from cooking, pets and household chemicals. This combination addresses both particulate matter and gaseous pollutants.

Is the touch screen difficult to operate?

The touch screen is designed for simplicity with clearly marked controls. You can easily adjust fan speeds, activate sleep mode, switch to turbo cleaning, or check filter status with single touches. The air quality indicator lights are clearly visible, showing red for poor air, yellow for moderate and blue for clean air. Most users find the interface intuitive and user-friendly.
