The truth is that persistent odours are not a definitive sign of poor cleaning.
In fact, in many cases, they are the result of odour-causing compounds becoming embedded in the room itself. Once that happens, standard cleaning may seem to improve things temporarily, but it is unlikely to fully remove the source of the smell.
This is especially true with incontinence odours, medical or bodily odours, stale room air, and smells that have built up over time in bedrooms, bathrooms, soft furnishings and communal spaces.
For care homes, this matters for more than comfort alone. It affects dignity, first impressions, staff morale and the overall feel of the environment. It can also become an issue in relation to expectations around cleanliness and premises standards.
Some odours are not produced by a single incident or remain in the air. They settle into the fabrics, furnishings and hidden spaces within a room.
That means the smell is no longer just in one place. It can be sitting in curtains, carpets, chairs, mattresses, bedding, skirting edges and other porous materials. In care settings, where the same room may be exposed to repeated incontinence-related incidents or ongoing medical and bodily odours, the odour problem can build over time.
This is why a room may smell a little better straight after cleaning but then seem “off” again a short time later. The room has been cleaned, the chemicals are masking things to some extent, but the odour source has not been fully neutralised.
Incontinence odours are particularly difficult because they are repeated, penetrating and easily absorbed into a room’s soft surfaces.
Even with good continence care, strong hygiene routines and fast housekeeping response, odour-causing compounds can remain behind in the room environment. The same can happen with certain medical odours, body odours and smells linked to reduced ventilation or long-term room use.
This is why fragrance sprays and ordinary air fresheners are not likely to solve the issue. At best, they may cover the smell for a short time. At worst, they simply mix with the original odour and make the environment feel even less fresh. In fact, they can contribute to that distinctive ‘care home smell’ that people associate unfairly with a lack of proper cleaning.
If you want to get rid of them, persistent odours need more than masking. They need a method that targets the odour itself.
A care home should feel clean, calm and reassuring from the moment someone walks in. Residents should not have to live with unpleasant smells as an accepted part of daily life. Families and visitors notice the atmosphere of a home immediately, and smell plays a major part in that first impression. Staff notice it too, especially when working long hours in enclosed or high-use areas.
Persistent odours can undermine the perception of otherwise excellent care. A room may look spotless, but if the air feels stale or unpleasant, the impression changes instantly.
There is also a regulatory expectation here. CQC guidance around Regulation 15: Premises and equipment, makes it very clear that premises and equipment should be clean and free from offensive or unpleasant odours. In practice, that reinforces the importance of maintaining a care environment that feels fresh, hygienic and well managed.
Many products on the market are just specifically designed to overpower bad smells with fragrance. That may create a short-lived improvement, but it does not necessarily deal with the underlying cause.
In care homes, the 'spray and cover' approach can be especially problematic. Strong perfumes and artificial fragrances are not always appropriate in residential environments, and they can sometimes irritate residents. They can also crucially make the perception worse and give visitors the impression that an odour problem is being disguised rather than resolved. In some cases they will also contribute to that unwanted 'care home' background odour.
The better question is not how to cover the smell.
It is how to destroy the compounds causing it.
Ozofresh uses ozone-based odour control to help clear odours at source rather than simply mask them.
Ozone is a highly reactive form of oxygen. When used correctly in odour-control treatment, it reacts with the compounds causing unpleasant smells and helps break them down. In practical terms, that means it is designed to target the odour itself rather than lay another scent over the top.
That is a major advantage in care settings, where smells linked to incontinence, medical care and room use are often embedded in the air and furnishings, not just sitting on visible surfaces.
Care home odours are rarely simple. They are often built up over time and spread across multiple surfaces and soft materials in the room.
That is why ozone treatment can be so effective. It is not trying to make the room smell stronger or sweeter. It is intended to deal with the odour-causing compounds that ordinary cleaning may leave behind.
For homes dealing with:
An ozone-based solution simply offers a more realistic long-term option than repeated fragrance use.
Ozofresh products can support care homes at different levels depending on the size of the problem and the type of space involved.
For day-to-day background odour management, the Ozofresh PlugIn can help maintain a fresher environment in appropriate settings.
For more intensive odour treatment in bedrooms and other affected spaces, products such as the Eclipse Pro and Eclipse Pro Max are designed to tackle deeper, more persistent odour issues.
This gives care providers options. Rather than relying on one-off sprays or constant fragrance use, homes can adopt a more structured odour-control approach based on the real nature of the problem.
Fresh air is not a luxury in a care home. It is part of the lived experience of the building.
A cleaner-smelling environment supports resident dignity. It reassures families and visitors. It helps staff work in more comfortable surroundings. It also strengthens the overall impression of quality, care and professionalism throughout the home.
That matters commercially as well as operationally. Homes are judged not only on what people see, but on how the environment feels.
Cleaning remains essential. But persistent odours often need an additional response.
The most effective long-term approach usually combines:
That is where Ozofresh adds value. It helps care homes address the cause of persistent odours, not just the symptoms.
A - Because the smell may already have been absorbed into fabrics, furnishings and other porous materials. Cleaning can remove visible contamination, but embedded odour compounds may remain behind.
A - NO ABSOLUTELY NOT. In many cases, they are the result of repeated exposure to strong odours, such as incontinence or bodily smells, over time. A room can be cleaned properly and still hold embedded odours.
A - It's a combination of factors. They are frequently reintroduced, they have a strong odour, we recognise them instantly, and the odour particles are easily absorbed into soft surfaces such as mattresses, chairs, carpets and curtains. This makes them much harder to eliminate with standard surface cleaning alone.
A - Usually not. Fragrance may offer a short-term improvement, but it does not tackle the source of the odour. In some cases, it can make the environment feel worse by mixing with the existing smell.
A - Ozone reacts with odour-causing compounds and helps break them down. This means it is aimed at clearing the odour itself rather than covering it up as chemical sprays do. With the particles gone, the odours are also gone. See more about how Ozone works.
The Ozofresh range includes 24/7 options such as the PlugIn for ongoing odour management in resident rooms and smaller areas, the Aura for corridors, and common areas. For more intense treatment in a vacant room, for example, during cleans for a change of resident, the Eclipse Pro and Eclipse Pro Max offer high-impact odour treatment for affected spaces.
Persistent odours in care homes are often more complex than they first appear. They are not always caused by poor cleaning. More often, they are the result of odours becoming embedded in the room and returning despite best efforts.
That is why care homes need more than a fragrance-based fix. They need a practical way to destroy odours at source and create an environment that feels clean, fresh and respectful.
