Pediatrician in the One-Day Hospitalization Department, Institute of Mother and Child
Polluted and too dry air in our apartments is one of the main reasons for greater susceptibility to infections in the autumn and winter, both in children and adults. The nasal mucosa dries out in inappropriate conditions, becoming less resistant to any infections that enter our body this way. Both viruses and bacteria then have an "easy task" and catarrhal symptoms appear much faster in such cases. Air purifying devices with humidification function and air humidity control are especially useful during this period and help to take care of children's health. Clean air also means better sleep quality. A well-rested and rested body - well regenerated during a long sleep certainly defends itself better against infections and improves our functioning during the day.

Allergist, Pediatrician, Pulmonary disease specialist
The quality of the air we breathe is fundamental to health. Chemical compounds that are the most harmful to our body are generated mainly inside buildings - formaldehyde, benzene, VOCs, NO2, odors and pollutants from the atmospheric air - particulate matter PM. In addition, the atmosphere of apartments contains bacteria, viruses and allergens (allergens of mites, fur animals, mold spores, pollen). Polluted air in apartments has an adverse effect on the health of residents, and people with chronic respiratory diseases, children and allergy sufferers are particularly sensitive to its effects. The toxic and irritating effects of air pollution may cause symptoms suggestive of infections or allergies, such as runny nose, cough, conjunctivitis, itching, and neurotoxic symptoms, such as headaches, irritability, fatigue or impaired concentration. On the other hand, too low humidity in rooms causes dryness of the mucous membranes of the nose, conjunctiva, skin, and sore throat. Air purification using devices equipped with HEPA filters with very high efficiency and its hygienic humidification with bacteria-free water improves the microclimate of rooms and the well-being of household members, especially children, people with allergies and asthma.
