How long does the battery last on a charge?

Pure Enrichment rates the PureSpa for several hours of misting per charge, but runtime drops if you use the light or run it continuously. Expect to recharge it every few days with daily use.

How often do I refill the tank?

The tank holds 3.4 fl oz, which covers roughly one evening or a workday of intermittent misting. Refill it whenever the auto shut-off stops the unit.

Is it good for a large living room?

No. It is sized for a desk, nightstand or small office. For a large open room, a plug-in diffuser with a bigger tank and stronger output works better.

Does it need to stay plugged in?

No. It runs on its rechargeable battery, so you can place it away from outlets. You charge it with the included cable and then use it cord-free.

What comes in the box?

You get the diffuser, a charging cable and a user guide. Essential oils are not included.

Is the PureSpa a good value?

It is a reasonable buy for a cordless diffuser of this size, since few rivals combine a battery, auto shut-off and a sub-one-pound body. Compare it with plug-in models if tank size and mist output matter more to you than portability.
