Top 5 myths about air purification in care homes

Care homes face growing pressure to manage air quality, reduce infection risks, and eliminate unpleasant odours. But in a crowded market of purification technologies and bold claims, it’s easy for misconceptions to spread. Here are five common myths about air purification in care homes and the facts that can help you make better decisions.

1. “Opening windows is all you need”
Natural ventilation can be helpful, but it’s not a complete solution. In cooler months this is not practical, in summer allergens can be a concern and at other times pollution. More importantly, open windows do not remove bacteria or odours, including those caused by VOCs (gases released from waste or cleaning products) already in the room.

The truth:

Airflow helps, but only systems that actively remove airborne contaminants can maintain safe and fresh indoor air consistently, especially in rooms that are regularly occupied.

2. “If it has a filter, it’s good enough”
Many air purifiers are sold on the strength of their filters, such as HEPA. While these can remove dust, some allergens and microorganisms, they can only impact air passing through the filter and do not destroy odours, furthermore performance drops as filters become clogged and blocked filters can be a hygiene risk.

The truth:

Filters trap, but do not neutralise contaminants, timely replacement of filters can be expensive and time consuming. Care homes need solutions that work continuously and reduce airborne bacteria, viruses, and unpleasant smells

3. “Fragrances make the air smell clean”
A pleasant smell can be reassuring, but it doesn’t always mean the air is clean. In care homes, odours from incontinence, food, and illness can be intense. Masking sprays often worsen the situation by layering artificial scents over persistent smells.

The truth:

Odour masking is not odour control. Removing the source of smells through air treatment is the only reliable way to improve indoor air quality.

4. “All air purification products do the same thing”
From plug-in ionisers to industrial air systems, there is a huge variation in how products work and what they are designed to do. Some focus on particles, others on gases or microorganisms. A unit that performs well in a domestic lounge may be ineffective in a care home bathroom.

The truth:

Care settings require tailored solutions. Choosing the wrong product can lead to wasted budgets and unresolved issues.

5. “Air purification replaces cleaning”
Air purification is a valuable addition, but not a substitute for regular cleaning, disinfection, and good hygiene practices. Used properly, it supports infection control and improves odour management, but surfaces still need to be maintained.

The truth:

No air system eliminates the need for cleaning. The best outcomes happen when air treatment works alongside strong hygiene standards.

Know what to look for

Understanding the capabilities and limits of different technologies is key to choosing the right solution. Independent test data, proven real-world results, and a track record in care settings should all guide your decision.
