pureAir 500 Room Purifier - Greentech Environmental

The pureAir 500 by Greentech Environmental is a compact air purification device designed for use in individual rooms and living spaces.

It combines ionisation, HEPA-type carbon filtration and activated oxygen technology to help manage airborne particles and unwanted odours.

With three selectable operating modes, the pureAir 500 offers different settings for everyday air purification and more intensive odour-control applications.

The pureAir 500 combines several air purification technologies:

• Ionisation: Electrically charges airborne particles, encouraging them to clump together and settle out of the air.
• HEPA-type carbon filtration: Helps capture airborne particles and provides additional filtration.
• Activated oxygen: Certain operating modes generate ozone (O₃), which reacts with odour-causing substances.

The device offers different modes depending on the type of air purification required.

Because ozone can irritate the respiratory system, it is important to follow the manufacturer's instructions and safety precautions.

The pureAir 500 is designed for areas of approximately 650–850 square feet (60–79 m²), according to the manufacturer's specifications.

Actual performance depends on factors such as ceiling height, ventilation, room layout and airflow.

The manufacturer's maximum coverage estimate assumes an open-plan space with ceilings approximately 2.6 metres high.

For best results, select a suitable operating location and follow the manufacturer's guidance.

The pureAir 500 features three operating modes, identified by different coloured indicator lights.

Green – Ionisation Mode

The default setting uses ionisation and filtration to help manage airborne particles.

Blue – Purification Mode

Combines ionisation with activated oxygen (ozone) generation for additional odour control. Follow all manufacturer safety precautions when using this mode.

Red – Away Mode

Runs a more intensive 30-minute ozone-generating cycle for tackling persistent odours.

Away Mode must only be used in unoccupied spaces. People and pets must remain out of the room during treatment and for at least two hours afterwards, as instructed by the manufacturer.

The pureAir 500 is designed to help manage unwanted indoor odours, including those associated with cooking, pets and general household activities.

Its ionisation and filtration functions provide everyday air purification, while its ozone-generating modes are designed for more intensive odour management.

Results will vary depending on the source and strength of the odour, room conditions and ventilation.

For persistent odours, identifying and removing the underlying source remains important.

The pureAir 500 uses ionisation and HEPA-type filtration to help manage airborne particles, including some pet dander.

Ionisation encourages particles to settle onto surfaces, where they can be removed through regular cleaning.

The device is not a substitute for vacuuming, dusting and good ventilation.

If you have pets, never use Away Mode while they are in the room, and observe the manufacturer's full re-entry precautions.

The pureAir 500's ionisation and filtration technologies are designed to help manage airborne particles, including dust and pollen.

However, the device's filtration efficiency for specific particle sizes has not been independently established in the product information provided.

For allergy management, a certified high-efficiency particulate air (HEPA) purifier with a suitable clean air delivery rate may be more appropriate.

Yes. The pureAir 500 generates ozone, also referred to as activated oxygen, when operating in certain modes.

The blue Purification Mode produces ozone, while the red Away Mode generates a higher concentration for intensive odour control.

Ozone can irritate the lungs and respiratory system, so the device must be operated strictly according to the manufacturer's instructions.

Away Mode must never be used while people or pets are present.

Away Mode is designed for more intensive odour management when a room is completely unoccupied.

When activated, the device runs a 30-minute ozone-generating cycle before returning to its previous setting or switching off, depending on its initial operating state.

Important safety precautions:

• Ensure all people and pets have left the room before starting Away Mode.
• Never enter the room while the cycle is running.
• Wait at least two hours after the treatment cycle has finished before re-entering.
• Follow the manufacturer's ventilation and safety instructions.

Away Mode should never be used in an occupied room.

The pureAir 500 offers a continuous ionisation setting for everyday operation.

However, the suitability of continuous use depends on the operating mode, room conditions and manufacturer's safety instructions.

Avoid prolonged or unnecessary exposure to ozone-generating modes, particularly in occupied spaces.

Always follow the instructions supplied with your device.

The manufacturer recommends cleaning the pureAir 500 at least once per month.

Before cleaning:

1. Switch off the device and disconnect it from the mains.
2. Remove the filter cover according to the user manual.
3. Carefully remove the filtration cartridge.
4. Use a vacuum cleaner or compressed air to remove accumulated dust and debris.
5. Reassemble the device before reconnecting the power supply.

Do not allow water to enter the unit, and always follow the manufacturer's maintenance instructions.
