When we need a air purifier?

Even when it is cold outside we must not neglect to renew the air in the house, especially if the walls and windows are thermally insulated, otherwise the risk of condensation increases by the high concentration of water vapor. It is often preferable to change the air during the day, but for short periods, not more than 5 minutes at a time: in this way the heat is superficial, and floors and walls are not too cool. 

If the outside temperature is around 4 ° C or lower, leaving the windows open for 15 minutes already an unnecessary waste of energy. Where possible, it is better to create air currents throughout the home, is opening the windows which appear on opposite facades of both the interior doors: to renew the air are sufficient even 2-3 minutes. In homes where there is no double-facing or where the opening window is limited, you must wait a few minutes more for an effective replacement. 

What's in the air we breathe 

Especially in cities, where traffic is always intense, and in industrial areas, the air of closed rooms, houses or offices, can be more polluted than outdoor. Depends on whether that comes into the house already saturated with fumes. Been further worsened by a number of other contaminants: residues in cigarette smoke, traces of detergent, vapors released from materials used to build furniture and for bonding carpet, upholstery, fumes caused by paints or insulation materials from fibers of the fabrics etc.. 

In addition, when we open the windows, entering the house also spores and pollen that give annoyance to those who suffer from allergies. Mites and pet hair to complete the list of troublesome pollutants. Exit routes blocked, sealing window frames that allow us to not disperse the heat from the heat, limit the replacement of air by increasing the concentration of harmful particles. 

Since we spend on average nearly 90 percent of the hours of the day indoors (of which 30 per cent in the job) the effects of air pollution can lead to illnesses ranging from general headaches, the fatigue, to the nausea, the dizziness and disorders of the respiratory tract, which suffers especially those already prone to allergies. 

The air of the house can be improved with modern purifiers household, after having sucked, they pass through the filters (to be washed often) with a mesh capable of retaining tiny particles and purify it. In many cases even the charge of negative ions, which are fundamental to the well-being and relaxation, which are eliminated by pollution. Other activated carbon filters used to retain odors. 

Here are the details of the substances in environments both external and internal: 

There are several pollutants that accumulate in an internal environment. 

Heating disperse particulates, asbestos, carbon monoxide and nitrogen dioxide. In particular asbseto is another name to indicate the asbestos (may be carcinogenic and its use in construction is prohibited for some years) and with particulate refers to a collection of toxic substances produced by the exhaust emissions of vehicles and other pollutants. It is made up of unburnt residues that remain suspended in the atmosphere causing pollution. 

Cookers gas producing carbon monoxide and nitrogen dioxide. 

The materials of construction resulting particulates, radon, asbestos, volatile organic compounds, pesticides and biological agents. 

Coming from the outside ozone, lead, particulates and biological agents. 

In addition to originate from the harmful substances are also produced within the home, for example, smoking or using sprays and detergents. 

All these substances are not easy to remove, an example is the dust that soon after being removed with a cloth, it rideposita quickly. 

Poor ventilation of the environment favors the concentration of pollutants because the reduced supply of outdoor air can not move outside the emissions resulting from internal sources. 

The merger may also be favored by high temperatures and humidity levels high. Even the air conditioning systems can promote the formation of mold and other biological contaminants that are spread throughout the building.
