Spring Allergies? How Proper Ventilation Can Help You Breathe Easier

Spring is a beautiful time here in Aotearoa, but for many, it's also a time of running noses, itching eyes, and sneezing. You know how frustrating it can be if you're one of the 1 in 4 Kiwis who suffer from hay fever and seasonal allergies. The challenge for people with asthma—about 20% of the population—isn't just pollen in the spring and mould spores in the damp winter months. While you can't control the air outside, you can take charge of the air inside your home.


Proper ventilation is the key to reducing allergens and improving indoor air quality, helping you breathe easier year-round.

Ventilation Systems: HRV vs. PPV

At GreenSide Energy Solutions, two highly effective systems to keep your home fresh and allergen-free: Heat Recovery Ventilation (HRV) and Positive Pressure Ventilation (PPV). Here's how each system works and when it's most useful:

  • Heat Recovery Ventilation (HRV): HRV brings fresh air into your home while recovering heat from the outgoing stale air. This system is ideal in winter, as it keeps your home warm without losing energy while also removing moisture to prevent mould growth—a major trigger for asthma sufferers. If you're looking to reduce dampness and improve air quality, HRV is an excellent choice.
  • Positive Pressure Ventilation (PPV): PPV pushes fresh, filtered air into your home and gently expels stale air. This system is particularly effective during spring and summer when pollen levels are high, as it reduces allergens in the air and improves overall airflow. PPV is an excellent option for homes that need better airflow, helping to clear out irritants like pollen and dust.

How Ventilation Improves Your Health

Whether clearing pollen in the spring or stopping mould in the winter, proper ventilation significantly improves your home environment. For allergy sufferers, better ventilation means fewer particles in the air that can irritate your sinuses or trigger asthma. A well-ventilated home also stays dry, which prevents mould from growing—another big win for your respiratory health.
