Ovelle Halo · Plug-in diffuser

  • No heat, no water, no wick
  • Runs on your schedule, not all day

Reviews

Loved in real homes

4.8Based on 87 reviews

Reviewers most often mention that it plugs straight into an outlet and frees up the shelf or counter their old diffuser used. It comes up again and again for hallways, powder rooms and guest rooms, where a low setting is plenty — though a few needed a minute with the app first.

  • Less stuff on the shelf

    Moved my old diffuser off the shelf and put this in the outlet. Got space for my books back.

  • Small but useful

    Got it for the powder room. No need for a big diffuser in there, this is a good fit.

    Amelia Young

  • The schedule is handy

    Set it for the hours we're home. Nice not having to remember another thing every day.

    Mark Roberts

  • Turn it down from my phone

    Handy when I want less smell without getting up. After the rain is my favorite in it so far.

    Mark Reed

  • Guest room sorted

    Got this for the guest room with white stillness. My mom kept saying how nice it smelled in there.

    Aaron Brooks

  • Pretty little thing

    I like the small light at the bottom. The white one looks good in our hallway.

Questions

Why not just buy a supermarket plug-in?

A supermarket plug-in warms a scented liquid continuously, on one setting, in a plastic housing. Halo mists undiluted fragrance oil with cold air, only in the hours you set, and is made to be seen. The fragrance is composed with a top, heart and base rather than blended for a refill aisle.

How long does a bottle last?

About 6–8 weeks per 100 ml (3.4 fl oz) bottle, depending on the intensity and schedule you set.

How big a room will it fill?

Up to 200 sq ft (18 m²) — powder rooms, bathrooms, hallways, entryways and bedrooms. For open living spaces, look at Ovelle Air.

Can I change scents?

Any time — unscrew one bottle and screw in the next. The Pair and the Ritual give you two to rotate by room or by season.

How do Ritual refills work?

Two 100 ml bottles arrive every 2 months at 15% off ($74.80). Skip a delivery, swap scents or cancel from your account — no calls, no fees.

When will it ship?

Free US shipping on orders over $125.

What if it’s not for me?

30-day returns on unused items in their original packaging. Email sales@houseofovelle.com and we’ll send a label.
