Frequently Asked Questions

Common questions about this comparison

Which purifier is better for large rooms?

The Blueair Blue Pure 211i Max is superior for large rooms, covering 635 sq ft and boasting a CADR of 406.4 for smoke. The Dyson Purifier Cool Formaldehyde TP09 does not specify its room coverage area, making Blueair the clear choice for expansive spaces.

What is the main difference in their air purification capabilities?

Blueair excels in general air purification for large spaces, with a smoke CADR of 406.4 and 635 sq ft coverage. Dyson focuses on detecting and destroying formaldehyde and capturing 0.3 micron particles, but lacks specified CADR or room coverage metrics for broader comparison.

Which product is quieter?

Blueair offers a minimum noise level of 23 dB, making it a very quiet option for sensitive environments. Dyson does not provide a minimum noise level specification in its details, so Blueair has a demonstrated advantage in quiet operation.

When should I choose the Dyson over Blueair?

Choose the Dyson Purifier Cool Formaldehyde TP09 if your primary concern is detecting and destroying formaldehyde, or if you value its integrated fan for direct cooling. However, for general large-room air purification based on CADR and coverage, Blueair is more explicit.
