Which is better for heating a room?

The HP11. It is the only one of the two that heats. The Pure Cool Tower cools and purifies but does not warm air.

Which purifies a room better?

Both use HEPA plus activated carbon. The HP11 has a fully sealed HEPA H13 system, which is the stronger spec on paper. The Pure Cool Tower lists a CADR of 72.8 for pollen.

Why is the HP11 rated lower?

The HP11 sits at 3.1 from 1,000 ratings while the Pure Cool Tower is at 4.8 from 499. The gap is large, so read owner comments on noise and heating performance before buying the HP11.

Can I control either from my phone?

Only the HP11. It connects over Wi-Fi and Bluetooth to the MyDyson app. The Pure Cool Tower is not Wi-Fi compatible and ships with a remote.

The Pure Cool Tower lists 33.8 dB on low and 56.9 dB on high. Dyson does not publish noise figures for the HP11 in this listing, so the tower is the safer pick for a bedroom.

Is the HP11 worth the extra?

Only if you need heating. If you just want purified cooling air, the Pure Cool Tower covers that and has far better owner ratings.
