When we talk about pollution, we too often overlook domestic pollution, which also claims victims, even though we could contain it with simple measures. Take the example of gas stoves (used by 60 percent of Italians), which, according to the World Health Organization, expose humans to deadly nitrogen dioxide (a respiratory irritant that causes asthma and bronchitis). According to the European Public Health Alliance (EPHA), gas stoves cause 43,000 deaths in Europe every year, 12,000 of which in Italy alone (we are number one in the European ranking). If you don't want to miss to the induction cooker, just ventilate the kitchen well, opening the windows during and after cooking, and use hoods and extractor fans to reduce the pollutants produced by cooking food.
Countermeasures for other key factors in household pollution are equally easy: smoking, harsh detergents and insecticides, and even pets.

The biggest pollutants in the home

A series of pollutants circulate in the home, for which, based on European directives and national regulations, thresholds and evaluation systems are established:

  • Sulfur dioxide, sulfur dioxide
  • Nitrogen dioxide and nitrogen oxides, particulate matter and lead
  • Benzene
  • Il carbon monoxide
  • Ozone
  • Polycyclic aromatic hydrocarbons (PAHs), cadmium, arsenic, nickel and mercury
  • Total suspended particulate matter (TSP)

Things to avoid

To clean the air in your home, first of all there are some things to avoid

  • Worn or disposable plastic food and drink containers.
  • Non-stick cooking utensils should be limited, however.
  • It is best to use wax paper or cling film in contact with food only according to the manufacturer's instructions.
  • When cooking, ensure adequate ventilation of the rooms and use the extractor hood.
  • Limit incense, candles, and cigarette smoke.
  • Change the air in closed spaces frequently.
  • Replace torn and/or worn out wrappings of foam-padded items (car seats, mattresses ...).
  • Limit clothing items with optional water-repellent or stain-resistant treatments.
  • Choose clothes of identifiable origin and composition.
  • Avoid foods with charred or burnt parts (Team Building included) and smoked.
  • In household materials, limit the use of soft PVC containing DEHP.
  • Don't let dust stagnate in closed spaces.
  • Perform adequate and periodic cleaning of the rooms and ensure proper maintenance of the vacuum cleaners (cleaning the filters and collection chamber, replacing the bags).

Things to do

The first and most effective natural remedy for cleaning the air in your home is definitely opening the windows. Even 5–10 minutes a day creates an air exchange that no natural remedy can match. Then there are these little tricks:
  • In summer, clean your air conditioning filters regularly, while in winter, keep fireplaces to a minimum.
  • When you bring new furniture into your home, keep the windows open longer, as they release chemical pollutants.
  • Prefer those to chemical insecticides, especially those in spray version, natural. 
  • Too much zeal in house cleaning is a waste of money and health. Harsh detergents don't clean the air, but rather increase indoor pollution.
  • Plants such as Sansevieria, Spathiphyllum, or Ficus elastica can contribute slightly to improving the environment, especially by increasing humidity and absorbing small amounts of nutrients.
  • Baking soda helps absorb odors (fridge, shoe racks, fabrics).
  • White vinegar neutralizes many odors and has a mild antibacterial effect. Lemon adds natural freshness without chemicals.
  • Lavender, eucalyptus, or tea tree can add a scent and have mild antibacterial properties. But they don't really "purify" the air: they mask odors rather than eliminate them. Use them in small quantities.
  • Regular cleaning: Dust, fabrics, and carpets accumulate allergens. Frequent cleaning reduces particles linked to problems like asthma or allergies.

The help of technology

Modern purifiers are the heart of home air technology. Models with filters HEPA They are able to capture fine dust, pollen, animal hair and some of the particles linked to indoor pollution.

Many also include:

  • activated carbon filters (against odors and chemical compounds)
  • automatic sensors that adjust power based on air quality

How to recognize a house with dirty air

If odors (cooking, humidity, smoke, animals) linger for a long time even after airing out, it is a typical sign of stagnant, "heavy" air and an accumulation of compounds in indoor pollution.

“Heavy” air can cause:

  • frequent headaches
  • tiredness or drowsiness for no reason
  • dry throat or irritated eyes
  • worsening of allergies or cold-like symptoms

These effects are often linked to the accumulation of CO₂, fine dust or VOCs (volatile chemical compounds).

Other clear signs of dirty air in the home are:

  • dark spots in corners or behind furniture
  • smell of “closed” or “cellar”
  • frequent condensation on the windows

This situation is often linked to insufficient ventilation and can affect breathing problems such as asthma.

Plants against indoor pollution

Finally, if trees can play a crucial role in combating outdoor pollution, at home or in the office, rely on some beautiful plants. The catalog is truly extensive, and we'll highlight four that are among the easiest to grow indoors: dracaena, gerbera, ficus, and ivy. Each of these plants has a specific function in absorbing harmful substances, and they all share one enormous advantage: for a small expense, you can enjoy the security of a healthier and more welcoming home.
