Living in New Zealand, we are all familiar with the horror of cold houses in the winter and stuffy spaces in the summer. In recent years, investing in a good ventilation system has become a necessity for Kiwis across the country. They dry out homes, combat mould and dampness, make spaces easier to heat, and can even assist with easing environment-driven health concerns. But how do they actually do it? 

As well as drawing out damp and stale air, a key function of any good ventilation system is air filtration. The filter on a ventilation system helps to catch the many unhealthy fibres that are often found in the air inside our homes. These are the same airborne particles that can contribute to setting off allergies and exacerbate asthma triggers. If you’ve found yourself wondering about these unhealthy fibres, how they can affect your health and home, and what they’re actually made of, we’re here to help!

Common airborne particles 

Below are some of the common types of matter that can be found inside New Zealand homes:

Smoke

Smoke is known to produce ultrafine particles which are deemed at higher risk of causing health effects than bigger airborne particles. This is due to the fact that they are small enough to directly enter the bloodstream after being breathed in. Sources of these ultrafine particles can include cooking indoors, burning candles, using gas appliances and fireplaces. 

The small size of these particles also makes it easier for them to move inside from the outdoors. This means that indoor air quality can be polluted by external sources of smoke as well, adding to the volume of ultrafine particles in the household.

The filter component of a high-quality ventilation system can help to reduce the presence of smoke and subsequent particles in a household. As many of the indoor activities which produce smoke can also be responsible for creating moisture in the home, a ventilation system will double to help regulate moisture levels as well, preventing dampness and growth of mould.

Atmospheric dust

Dust is produced by almost everything around us. Human hair, dirt from outside, pollen, pollution, soot and building sites all have fine particles that create dust. When these particles become airborne, they often make their way indoors and can accumulate on windowsills and belongings and even contribute to allergy symptoms.

Eyes can become irritated by dust, the health of indoor plants can be impacted and when built up, atmospheric dust can simply make a mess. Atmospheric dust contributes to poor indoor air quality which can be significantly reduced by air filtration through a good ventilation system.

Bacteria

Recent studies have indicated that bacteria is spread in more ways than previously believed. Something as simple as flushing a toilet with the seat up can disperse airborne bacteria around your home. While not all types of bacteria are harmful, there are certain components of some bacteria, such as endotoxin, which are often found in households and have been linked to health concerns like worsening asthma and allergy symptoms.

Dampness is a leading contributor to the growth of bacteria and mould in households. This means that the best way to control bacteria is by reducing moisture in the household through ventilation and managing indoor humidity levels. HRV ventilation systems not only help to filter out bad bacteria and improve indoor air quality but also to cultivate an environment which prevents the growth of bacteria and potentially hazardous matter.

Spores and pollen

Spores and pollen from plants are other substances that have been known to make their way into New Zealand homes and are often associated with triggering hay fever and asthma symptoms. As we live in a country that is rich in greenery, it can be difficult to avoid pollen and subsequent health effects. 

Common symptoms of hay fever include:

  • Sneezing
  • Blocked nose
  • Running nose
  • Watery, puffy and itchy eyes
  • Poor sleep
  • Difficulty controlling asthma symptoms

The filter in the HRV ventilation system can assist with reducing exposure to allergens, improving indoor air quality and combating environmental influencers that can make hay fever season particularly uncomfortable for many Kiwis.
