Changing indoor air

Our good health is increasingly threatened by dangerous contaminants that are often undetectable. If we want to stay healthy, we need to live and breathe in healthy environments.

This is why it is so important to replace the indoor air.
As long as you change it with clean air.

Change the air: make your home healthy

Inadequate ventilation can make buildings unhealthy.
One of the effects of unhealthy buildings is sick building syndrome.
If a building is unhealthy, its occupants also end up feeling unwell.
The real problem is that we're not always aware of the danger.

Many pollutants are undetectable, while others are commonly thought to be helpful (air fresheners), pleasant (scented candles) or sanitising (cleaning products).

Radon and monossido di carbonio are very dangerous but odourless and colourless: you might notice a stale, stuffy smell when you first enter a crowded workplace or a classroom during a lesson, which means the pollution tolerance levels have been exceeded.

Anyone who is already inside those environments won't notice the musty air because they have adapted to it: this is another form of indoor air pollution that mustn't be underestimated.

We can't see or smell dust mites either but they pose a major risk to allergy sufferers.
Mould spores are particularly harmful and can trigger asthma attacks or serious respiratory disease.
At the same time, our metabolism and our routine activities also produce humidity.
As do our pets.

The substances contained in household cleaning products can also increase air pollution by emitting chemical compounds.

A lot of our buildings are also contaminated by off-gassing of formaldehyde, a carcinogenic substance commonly found in floors, furniture and other household products.

We do 24,000 breaths a day,
we deserve a better air

Indoor pollution is responsible for 2.7% of the global disease burden worldwide (Global Health Risks: Mortality and burden of disease attributable to selected major risks WHO, 2009) and 7.6% of deaths (Global Health Observatory, 2016).

Do the right thing:
change the air with mechanical ventilation solutions


ISO 17772-1:2017

Indoor environmental quality

According to applicable legislation, the minimum ventilation parameters for indoor environmental quality is established as 14,4 m3/h per person.

Changing indoor air with Open windows

Open windows

  • Too cold in winter
  • Too hot in summer
  • Draughts
  • Outside noise (traffic)
  • Possible break-ins
  • No filtration of incoming air
Changing indoor air with Closed windows

Closed windows

  • Sealed building
  • No air change
  • Sick building syndrome
  • High risk of mould
  • Persistence of unpleasant smells
  • Build-up of indoor pollution

How to change the air in confined environments

Thesan Aircare

Uncontrolled pollution is a dramatic health problem for society.
It may be complicated to reduce it at a global level but it can be addressed at home with appropriate mechanical controlled ventilation systems, that can:

  • change, filter and clean air, all with low energy consumption
  • keep pollutants and allergens at harmless concentrations for humans and pets

Indoor air is the most polluted and dangerous.
Aircare filters it, cleans it and returns it to you “ready to breathe”.

  • Aircare AF
  • Aircare ES
  • Aircare AE
Ricambiare l'aria senza avere infiltrazioni di acqua


The outdoor air flows into your Aircare unit through the external grilles.
These grilles are fitted with hoods that automatically close when the external pressure exceeds certain thresholds (about 300 Pa that corresponds to a wind speed of about 70 km/h) to stop rain from seeping in.
When the wind pressure is lower, no water seeps in from outdoors.
Ricambiare l'aria di casa con diversa umidità e temperatura


Aircare ES has two humidity and temperature sensors.
We recommend keeping Aircare in Automatic Mode: the device automatically adjusts and manages changes in humidity levels as well as any other climate situation.
Quanto consuma un sistema di vmc per ricambiare l'aria di casa


Always. Mechanical Ventilation with Heat Recovery (MVHR) systems are created to:
  • ensure the correct change of air in our living environments (homes, workplaces etc.)
  • run 24/7


Its very low energy consumption means you won't have any unpleasant surprises on your power bill: even when Aircare operates continuously, it only consumes as much as one coffee per month!
