Did you know that summer is one of the most air-polluted seasons?

Summer is often associated with nature, warmth, and holidays. However, during this season, air quality can often deteriorate — sometimes even more than in spring or autumn. But why does this happen?

While in winter the main source of air pollution is heating, in summer many other pollution sources appear:

✅ Increased traffic, especially in cities and tourist areas

✅ Forest and grassland fires

✅ Smoke from barbecues and grills

✅ Heat smog (photochemical smog)

✅ Intense pollen season

✅ Drought and dust

For every problem – the right filter

Dust

Do you live near a gravel road or construction site? G4-class filters are effective at trapping dust. However, if dust levels are high, filters will clog faster — so it’s worth checking and replacing them regularly. If possible, use a G4 pre-filter (for example, in Blauberg, Recom, or Brofer ventilation units).

Odors and smoke
Want to avoid smells from barbecues, forest fires, or traffic? Activated carbon filters are best — they not only absorb unpleasant odors but also capture some harmful gases and smog.

How often should you replace filters in summer?

Due to higher pollution in summer, filters may need to be replaced more often than usual. Check them at least once every 3–4 months, especially after prolonged heat or smoky periods. An important indicator: reduced fresh air flow.
