It is very common for the air in our home to become saturated and as a consequence, we develop different ailments without knowing what is related to the quality of the air in our home. We give you tips to improve air quality at home.

Did you know that many times headaches, colds, allergies, and other common ailments are related to the air we breathe at home? We are going to see the problems and solutions that the lack of air quality at home entails because it turns out that it is not always in optimal conditions for health.

The level of interior contamination of a home usually exceeds the exterior. This is because the pollution that enters through the windows is added to that generated within the home itself. This, even if it surprises you, occurs even in big cities.


We divide the most common problems that usually develop in a home into two groups:

1. The particlesAir quality at home

Included here: dust, smoke, pollen … as well as particles of biological origin such as mites, bacteria, and molds. Also included in this group are the particles generated by combustion devices.

A trigger for its appearance is usually humidity. In fact, in humid environments where ventilation is not adequate, mold and mite problems are very frequent, which are the culprit of unwanted allergies and respiratory problems.

2. Carbon dioxide and common pollutantsAir quality at home

The technicality used for these gases is VOC, Volatile Organic Components, and they are derived from different products, many of them quite common in a home: paints, varnishes or waxes, repellents, air flavorings … and especially cleaning products.

With household cleaning products you have to be very careful and whenever you handle them you have to do good ventilation because inhaling the gases given off can be very toxic to health.


A risk derived precisely from the advances in the field of construction and the race towards energy saving is that homes are committed to hermeticity and disregard the old forms of natural ventilation, which mainly consisted of making cracks in the buildings that would ensure ventilation. This change increases the danger of poor air quality.

When it comes to ending the problem and improving the air quality of the home, we have several possibilities:

Crossed ventilation

Cross-flow ventilation takes only five minutes to regain air quality. At this time, walls and ceilings do not change their temperature. So energy loss is relatively small and air renewal is more than enough. But watch out for a time, since the excess will lead to a waste of energy.

Controlled ventilation

Ventilation by filters or devices installed on windows is generally very slow. More than an hour is required to achieve adequate air renewal. At this time the loss of energy is important, hence cross ventilation is postulated the winner.

Air purifiers

These systems have a fan that passes air through a filter and then expels it. There are a wide variety of models on the market, from the simplest to devices that incorporate sophisticated filtering techniques such as ionization or the UVA method.
