Which is better for a bedroom?

The Winix 5500-2, because it runs as low as 27 dB and covers 360 sq ft. The Dyson gives no noise figure, so it is harder to judge for sleep.

Does the Dyson replace a separate heater and fan?

Yes. It is a three-in-one heater, bladeless cooling fan, and HEPA purifier, so it can replace two other appliances.

Both use HEPA. The Dyson captures 99.97% of particles down to 0.3 microns; the Winix adds a washable pre-filter and PlasmaWave. The Winix lists a 246 pollen CADR; the Dyson lists none.
