The first warm week of summer usually feels positive. Windows open, buildings feel brighter, and outdoor spaces become busier.

But for many workplaces, summer quietly introduces a problem most people do not immediately notice, Pollen.

Every time someone walks through a door, allergens are carried inside on clothing, shoes, bags and even hair. Throughout the day, those particles settle into carpets, office chairs, entrance matting and communal spaces before slowly circulating around the building.

And in busy environments, it builds up quickly.

For facilities management teams, summer is no longer just about keeping spaces visually clean.

It is about helping create healthier indoor environments.

Many people assume hay fever symptoms only come from being outdoors.

In reality, poor indoor cleaning and ventilation can make symptoms even worse once allergens become trapped inside a building.

Sneezing, itchy eyes, headaches and congestion often become more common in offices and shared spaces during summer, especially in buildings with high footfall or older ventilation systems.

Something as simple as dry dusting can push pollen and dust straight back into the air rather than removing it.

And once allergens settle into carpets and soft furnishings, they continue circulating throughout the day.

The way buildings are cleaned during summer matters far more than people realise.

Small changes in cleaning methods can make a major difference to indoor air quality and overall comfort for staff and visitors.

Using damp cloths instead of dry dusters helps trap allergens rather than spread them. HEPA filter vacuums help capture fine particles like pollen and dust, while more frequent cleaning of entrances, floors and communal touchpoints reduces the amount being carried around the building.

Even air conditioning filters play a huge role.

If they are not maintained properly, they can end up circulating allergens rather than improving airflow.

Facilities management is becoming far more connected to wellbeing.

Businesses are starting to understand that a cleaner environment does not just improve appearance, it changes how people feel inside a building.

Cleaner air, fresher spaces and reduced allergen build up can all contribute towards a more comfortable workplace experience during summer months.

Especially in offices, schools, retail spaces and communal buildings where people spend long periods indoors.

During summer, people become far more aware of their environment.

Dust sitting on surfaces, heavy air, musty smells and dirty entrance flooring all become more noticeable once temperatures rise.

Customers notice it. Staff notice it. Visitors notice it.

And while most people may never directly say “this building has poor air quality”, they do notice when a space feels fresh, clean and well maintained.

That is where proactive cleaning makes the biggest difference.

At Merco summer cleaning is about more than maintaining appearances.

It is about helping create cleaner, fresher and more comfortable environments for the people using them every day.

Because good facilities management does not just support buildings. It supports the people inside them too.
