Can I Leave My Windows Open While Using My PRISM+ Air Purifier?
Answers to the things customers ask most. Search for a keyword, or browse the list below to jump to your answer.
Yes, you can leave your windows open while using your PRISM+ Air Purifier.
However, for the best air purification performance, we recommend keeping doors and windows closed whenever possible.
Why Does Closing Windows Help?
Air purifiers work by continuously filtering the air within a room.
When windows or doors are open:
- Outdoor air constantly enters the room
- New dust, pollen, smoke, and pollutants can be introduced
- The air purifier has to work harder to maintain good air quality
As a result, the purifier may take longer to improve the air quality compared to a fully enclosed room.
Will My Air Purifier Still Work?
Yes.
Your PRISM+ Air Purifier will continue filtering the air even when windows are open.
The difference is that the purifier may be processing a continuous flow of new particles entering from outside.
Think of it this way:
When Should I Keep the Windows Closed?
For optimal performance, keep windows and doors closed when:
✓ Running the purifier for allergy relief
✓ Reducing dust and airborne particles
✓ Improving indoor air quality quickly
✓ During haze, smoke, or high-pollution conditions
✓ Using Auto Mode to maintain a specific air quality level
When Is It Okay to Open the Windows?
Opening windows may be beneficial when:
✓ Ventilating the room
✓ Reducing indoor odours
✓ Bringing in fresh outdoor air when air quality is good
✓ After cleaning or cooking
Your air purifier can continue operating normally during these situations.
