Fresh Air Affects Indoor Air Quality

Fresh Air Affects The Quality Of The Indoor Air

The amount of fresh air from outside has a direct effect on the quality of the indoor air and the air you and your family breathes. Stale air can lead to an increase in airborne dust, chemicals or VOC’s as well as other gases, odours, mould spores as well as airborne bacteria and viruses.

Imagine a plastic bubble. Everything that is created inside the plastic bubble stays unless new and fresh air can push out the stale air. Our homes are no different. These days, windows and doors have almost air tight seals for energy efficiency. In other words, leaky windows and doors that used to allow air flow into the home are a thing of the past. So whatever is created indoors…stays.

In many cases you need air quality instruments to determine if there is adequate air flow into a building or a home. Usually, the best way to determine proper air flow or air exchange is by determining the level of Carbon Dioxide or CO2. CO2 is exhaled by occupants of the home (people and pets) and can give us an accurate reading on how well the home naturally ventilates gases and particles. High CO2 means poor air flow and poor air quality.

High CO2 levels can lead to a variety of health issues:

Sleep Apnea
Respiratory issues
Sinus issues
Hypercapnia (rise in CO2 in the blood)

Poor ventilation can lead to a variety of indoor air quality pollution issues:

Increase in relative humidity and condensation on windows and outer walls
Odour issues
Mould growth
Increase in Volatile Organic Compounds or VOC’s
Increase in airborne particulate and dust.

So how do we solve this issues in our homes? Lately most new home construction in the GTA mandates that new homes have a ventilation system installed or a Heat Recovery Ventilation System or HRV. Ventilation systems are like mechanical lungs for the home, they mechanically bring in fresh air from outdoors and vent out stale air. This increase in air flow dilutes the indoor air of pollutants and pushes polluted air back outside. It’s almost like permanently leaving a window open without the energy loss. So in summer you don’t lose air conditioning and in winter you don’t lose heat…but get lots of fresh air.

A Heat Recovery Ventilation System (HRV) or Energy Recovery Ventilation System (ERV) is the best solution to bring fresh air into your home. No more odours, no more condensation and much healthier indoor air for a healthier home.

Bionic Healthy Home specializes in proper sizing, installation and balancing of ventilation systems to bring fresh air into the air your breathe. Experience good indoor air quality with a Bionic Healthy Home ventilation system.
