Improve your health, and indoor air quality

With an i-vent house ventilation system, air is replaced two to four times per hour on average. This helps improve indoor air quality by expelling unhealthy bugs and allergens. The risk of asthma and other respiratory health problems will dramatically reduce through a serious reduction of damp air, mould spores, dust mites and the unwanted chemicals produced from appliances, cleaning products and other household pollutants. By tackling indoor air quality, you can make a real difference to the health of everyone in your home.


Avoid moisture and mould with ventilation

Say goodbye to moisture and mould

The average home produces 30 litres of moisture a day. All that moisture creates the perfect environment for some nasty moulds and pathogens. There’s no need to put up with this when ventilation fans can solve the problem for you.

The facts

• 46% of New Zealand homes suffer from condensation.
• 35% of New Zealand homes have visible mould.

What are the health risks with mould and moisture in homes?

Today’s construction and house renovation techniques are aimed at creating airtight insulated homes. These are easier to heat and they help residents save on energy usage. However, moisture generated by normal activities such as washing and cooking is then trapped indoors, creating ideal conditions for mould to flourish in.

Health problems associated with high levels of airborne mould spores include asthma episodes, allergic reactions, irritations of the eye, nose and throat, and sinus congestion.

It gets worse. Certain types of moulds, such as Stachybotrys Chartarum (SC), may produce compounds that have other toxic properties, called mycotoxins. SC is a greenish black mould that grows on material with high cellulose content, such as fibreboard, the paper covering of gypsum wallboard, wallpaper, dust and wood.Asthma is a serious health issue in New Zealand, with many homes harbouring from high levels of allergens and pollen. The solution is to improve indoor air quality with a steady flow of filtered air from a house ventilation system.

If you find mould growing indoors it’s a clear warning sign that you are living in an unhealthy environment. Affected surfaces should be cleaned thoroughly to remove the problems caused by moisture in homes. For a long-term solution, talk to Harrisons about an i-vent ventilation system.

Tackle asthma & home allergies

Clean, green New Zealand is paradise for trees and grass. Unfortunately, plants produce pollen in abundance, which makes life difficult for those unlucky enough to suffer from allergies. When you include the other common home allergens, such as dust mites and cat fur, our homes can easily become places of non-stop sneezing and snuffling.

The facts

• Up to 30% of adults and up to 40% of children have allergic rhinitis.
• The grass pollen season can last from August to March.

What are the health risks with pollen and allergies?

Hayfever (Seasonal Allergic Rhinitis) is extremely common in New Zealand. Symptoms include a recurrent runny nose, feeling ‘bunged up’ and sneezing. The eyes, throat and ears may also be itchy. Persistent hayfever or allergic rhinitis may cause obstructive sleep apnoea, due to breathing difficulties during sleep. This leads to reduced airflow, a drop in oxygen levels and disturbed sleep. On top of that, asthma at home has been shown to be more difficult to control unless allergic rhinitis is also managed.

The grass pollen season can last from August to March.

Pollen is a recognised trigger for asthma attacks. One in six New Zealand adults and one in four of our children experience asthma symptoms, and asthma is the most common cause of admission to hospital for children.

Asthma is a serious condition that may require a range of therapies and medical intervention to bring it under control. Filtering the air that enters your home can ensure there’s a steady flow of clean air throughout the day and night, with home allergens kept out by the highly efficient i-vent filter.
