How large a room can the Shark HP302 clean?

Shark rates it for rooms up to 1,400 square feet. That figure assumes open space and typical ceiling heights, so real coverage in closed rooms with furniture will be lower.

Does the Shark HP302 work with an app or voice assistant?

No. It has no app control and no voice control. Everything is done from the controls and display on the unit.

What filter does the Shark HP302 use?

It uses a HEPA filter, and one is included. There is no separate washable pre-filter listed, so plan on replacing the HEPA filter as Shark directs.

How much power does it draw?

Up to 54 watts. That is typical for a purifier of this size and is far less than a space heater or air conditioner.

Does it shut off on its own?

Yes. It has an automatic shutdown feature, which is useful if you run it on a timer or leave it unattended.

Is the Shark HP302 a good choice over a smart purifier?

Choose it if you want large-room coverage with simple physical controls. Pick a connected rival if you need app scheduling, voice commands or automatic fan changes based on air quality.
