Ventilation, as a broad term, refers to the process by which clean, outdoor air is introduced into an area while stale or polluted air is often simultaneously removed.
But why is ventilation important?
1) Health benefits – a poorly ventilated indoor space can exacerbate pre-existing health conditions including asthma, allergies, rashes and sinusitis. An effective ventilation system will filter out larger particle pollens, alleviating the symptoms of hay fever.
2) To remove condensation – most noticeable in winter but a problem throughout the year, condensation is a common form of dampness and can lead to mould growth and long-term damage in the absence of sufficient ventilation.
