Which is better for a bedroom?

The HP04 is the better pick for a bedroom. It has a sleep timer, automatic shut-off and 350° oscillation, and it costs $200 less. The HP11 runs up to 63 dB, which is loud for sleeping.

Is the HP11 worth $200 more than the HP04?

Only if sealed HEPA H13 filtration and odor removal matter to you. The HP11 adds a fully sealed filter system, carbon odor control and Siri support. The HP04 does the same heating, cooling and purifying jobs for $249.99 at ShopSimon as of November 7, 2026.

Which one purifies air better?

Both capture 99.97% of particles down to 0.3 microns. The HP11 goes further by sealing the whole machine to HEPA H13 grade and adding an activated carbon filter for odors. The HP04 has no sealed-machine or odor claim.

Neither listing states a motor or warranty life. The HP04 has the stronger owner rating, 4.2 from 1,700 ratings versus 3.1 from 1,000 for the HP11, which is the better signal on long-term satisfaction. Both need filter replacements on Dyson's schedule.

Do both heat and cool?

Yes. Both are heater, fan and purifier in one tower. Neither is an air conditioner; the cooling mode is a fan only. The HP04 adds 350° oscillation, which the HP11 specs do not list.

Can I control them by voice?

The HP11 works with Alexa, Google Assistant and Siri through the MyDyson app. The HP04 connects to the Dyson Link app, and its listing does not name voice assistants.
