POLLEN! Know why it is harmful to respiratory health


Pollen is a fine to course powdery substance that contains grains, which are small proteins that are considered allergens (capable of triggering allergies).  Some species of plants are more responsible for the onset of rhinitis, or even asthma.

Pollen is microscopic and is easily dispersed through the air. Once deposited in the nasal cavity, it gives rise to the inflammatory response characteristic of rhinitis and asthma.

When pollen grains are whole, they tend to remain in the upper airways because of their size – about 10 micrometers or more.

In this case, by releasing their allergens, they cause reactions, such as sneezing, runny nose, watery eyes and other typical symptoms of rhinitis. However, they are not always whole and can be transported to the lung alveoli (deeper areas of the lung) where asthma attacks may develop.


It is known that pollen may be responsible for allergic (seasonal) rhinitis, also called hay fever. This type of rhinitis is more frequent in the spring when the most significant release of pollen by flowers, trees, and grasses occurs.

Cases of hay fever have been increasing. Studies indicate that part of the phenomenon of increased pollen allergies in most industrialized countries is a result of emissions of high levels of nitrogen dioxide and ozone from vehicles.

In allergic individuals, exposure to air pollution acts in conjunction with pollen, aggravating the symptoms of hay fever.


Hot, sunny, dry, windy days are very tricky for allergy sufferers, because of the large number of pollens circulating in the air.

In addition to the uncomfortable symptoms of allergic rhinitis, there are other factors to consider, such as loss of productivity at work and school due to insomnia and fatigue. 

It is crucial for those who know they have allergic reactions to pollen should avoid contact with it as best as they can. 


– Keep the windows of your house and car closed during the times of day when the release of pollens are high. You can do this by checking out the pollen in your region:

– Wear sunglasses

– Avoid open places with grasses

– Replace the filter in your car

– Use an air purifier


Airfree Air Purifier utilize a unique and patented technology, which consists of heating particles inside a ceramic core.

When passing through the apparatus, particles like pollen grains are incinerated and their allergens undergo a process of change that leads to their inactivation.

The heated air is cooled before leaving the appliance, so that there is no change in the ambient conditions. In addition to their award-winning designs, the various models are maintenance-free and energy-efficient.
