How much different is in formaldehyde and VOC removal capabilities between Big+Quiet (BP04) and Hot+Cool (HP09)? | Dyson Community
Skip to main content

I’ll buying air purifier for my house, because formaldehyde and VOC level is very high.

(formaldehyde: 0.4~1.2mg/㎥, VOC: 0.6~2.4mg/㎥)

 

My candidate purifiers are Big+Quiet (BP04) and Hot+Cool (HP09) Formaldehyde.

The selection is a bit difficult.

My room is about 16㎡, but formaldehyde and VOC level is high.

 

Anyone who bought or tested these two models, 

How much different is in formaldehyde and VOC removal capabilities between these two?

Do you think HP09 is enough to remove the gases in my room?

These are two totally different machines. The HP09 is also a heater, whereas the BP04 ist just an air purifier. The BP04 is designed for larger spaces than the HP09. You room space is fairly small. If you really just want something to capture pollutants from your air I would choose the TP09.
