Closed atmospheres where the air is not allowed to circulate tend to cause these types of grievances, or even aggravate them into minor allergies or colds.

Specific products can be purchased to preserve the fresh air in a home located in the city or close to a busy road purifying the air and creating a healthier atmosphere in your home.

HEPA Air Filters
HEPA (High Efficiency Particulate Air) is a globally-accepted filter system to control pollution in the home. Its capacity can filter up to 99.9% of the particles larger or equal to 0.3 micros suspended in the air.

The HEPA system, developed during World War II, is the most commonly-found system in commercially available filter apparatus, although it is sometimes boosted with HEGA (High Efficiency Gas Absorption). This system effectively absorbs gases and volatile substances by using the mineral Zeolite. Thanks to its crystalline structure Zeolite traps and absorbs large quantities of odours and gases, and is thus a highly effective air purifier.

Ion Generators
Another commercially available option are negative ion generators, which not only improve air quality but are also very positive for all those who suffer from allergies. Negative ions are molecules that have gained an electron; they are created by nature, the wind, storms and water. In cities with high levels of pollution, positive ions are largely present to the detriment of negative ions.

Negative ions are an ideal way of improving the atmosphere in a room: they help to neutralise foul odours, reduce contamination, freshen up the air and prevent headaches or stinging eyes provoked by closed surroundings. They also reduce tiredness, anxiety and irritability.

Humidifiers
Finally humidifiers should also be mentioned. In dry climates, humidifiers restore humidity to its correct level (45-65%), improving respiration and helping to prevent common infections of the respiratory system.
