Ovelle Halo plug-in diffuser in matte black on a travertine surface
From the founder · Ovelle Halo

Why our plug-in is $89.

Three decisions made it cost more than the one in the supermarket: a matte body you’d put on show, cold-air diffusion so the oil is never watered down, and twelve fragrances composed with a top, heart and base. If you want a cheap plug-in, buy one. If you want the room to feel finished, this is for you.

  • Composed fragrance, not refill-aisle scent
  • Cold-air mist — no heat, no dilution
  • Refills from about $0.67 a day

How it works

What $89 actually buys.

  1. 1The deviceA palm-sized matte body in black or white, a recessed control panel and a soft glow at the base — designed to stay out on show.
  2. 2The diffusionCold air, not heat: the oil is misted undiluted, so the scent is the one that was composed, at the strength you set.
  3. 3The fragranceA 100 ml bottle that screws straight in and lasts 6–8 weeks, from twelve signatures built like fine fragrance.

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.

    Ava Carter

  • 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 is it more than a supermarket plug-in?

You’re paying for three things: the body, the diffusion and the fragrance. Aluminium-look matte housing instead of printed plastic

cold-air misting of undiluted oil instead of a warmed liquid

and scents composed with a top, heart and base instead of blended for a refill aisle.

What does it cost to keep running?

A 100 ml bottle is $44, or $37.40 on the Ritual, and lasts 6–8 weeks — about $0.67–$0.89 a day per diffuser.

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.

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.
