How long does an ozone treatment of a hotel room take?

It depends on the room size and how strong the odor is. The machine shows a suitable treatment time when you set the room size — typically a few hours including airing out. Many properties run the treatment as part of the turnaround between two bookings.

Does an ozone treatment remove cigarette smoke smell?

Yes. Ozone breaks down the odor molecules from smoke at the source, including in textiles, curtains and bedding — instead of masking the smell the way sprays do. Smoke is one of the most common reasons hospitality properties use ozone generators.

Can guests be in the room during treatment?

No — an ozone treatment is always done in an empty room, with no people, animals or plants, and the room is aired out afterwards. That is why it fits naturally into the gap between check-out and check-in.

How hotels and villas remove smoke and damp smells between bookings

The short answer: you cannot spray away a smell a guest will notice. Properties that get rid of smoke, damp and kitchen odors for real use an ozone deep treatment in the empty room between bookings — and an ozone-free air purifier running in rooms while guests stay.

One smell in one room can cost a rating

Guest turnover is relentless: every check-out leaves traces — smoke on a balcony that drifted inside, damp towels, kitchen smells in a villa, a pet that was not supposed to be there. The next guest walks in within hours, and the review often mentions the first thing they notice: how the room smells.

Air fresheners mask; they do not remove. The odor molecules sit in textiles, mattresses, curtains and the air itself.

The turnaround routine that works

1. Deep treatment between bookings. An ozone generator like Ozoneair Clean is made for exactly this window. Housekeeping finishes, the machine runs in the closed, empty room, and the room is aired out before check-in. Smoke, damp and food odors are broken down at the source — the room smells of nothing at all, which is exactly what a fresh room should smell like. Choose the model by room size: Clean 30 for standard rooms, Clean 60 for suites and Clean 120 for whole villas and larger spaces.

2. Continuous purification in occupied rooms. In lobbies, restaurants and rooms where guests stay, an ozone-free air purifier like Ozoneair Purify runs quietly 24/7 — removing dust, allergens, spores and everyday odors while the space is in use. It is safe with people in the room and needs nothing more than a wall socket.

3. Textiles. For upholstery, mattresses and curtains that carry smells of their own, Ozoneair Wash & Steam deep-cleans textiles without chemicals.
