As the seasons change, so does the air around us. For millions of people, this shift brings more than just warmer days and blooming nature - it marks the beginning of allergy season.

Did you know that around 20% of people in Europe have a pollen allergy?
That means every fifth person is affected — often without even realizing how much indoor air quality plays a role.

What causes seasonal allergies?
Seasonal allergies, also known as hay fever, are triggered by airborne allergens, most commonly pollen. These microscopic particles are released by plants as part of their reproductive cycle and can travel long distances through the air.

The most common types of pollen include:

• Tree pollen – dominant in early spring (birch, oak, alder)
• Grass pollen – peaks in late spring and early summer
• Weed pollen – common in late summer and autumn (ragweed, mugwort)
  

Because pollen particles are extremely small and lightweight, they easily enter indoor spaces - even when windows are closed.

Why indoor air matters more than you think.

While many people associate allergies with the outdoors, studies show that we spend up to 90% of our time indoors. Unfortunately, indoor air can accumulate pollen, dust, pet dander, and other irritants, creating a constant exposure environment.
Without proper filtration, allergens settle on furniture, circulate through the air, and continue to trigger symptoms such as:

• Sneezing and runny nose
• Itchy eyes and throat
• Fatigue and poor sleep
• Breathing difficulties

How air purifiers help during allergy season
A high-quality air purifier can significantly reduce the concentration of airborne allergens indoors.

Devices equipped with a HEPA filter are particularly effective, as they capture up to 99.97% of particles as small as 0.3 microns, including pollen.

By continuously circulating and cleaning the air, purifiers create a controlled indoor environment, helping to minimize allergy triggers and improve overall comfort.

Practical tips to reduce pollen exposure
In addition to using an air purifier, small daily habits can make a big difference:

• Keep windows closed during high pollen days
• Shower and change clothes after being outdoors
• Vacuum regularly using a HEPA-equipped vacuum cleaner
• Dry laundry indoors during peak pollen season
• Monitor daily pollen forecasts

Breathe better this season
Allergy season doesn’t have to mean constant discomfort. By understanding what’s in the air and taking proactive steps, you can create a healthier indoor space.
