Indoor plants that clean the air: fact or fiction?
18 July 2019
It’s appealing to think that house plants can do double duty - looking gorgeous and also cleaning the air in your home.
House plants were hugely popular in the 1970s and 80s, and now they’re making a big comeback. Garden centres throughout New Zealand have an ever-expanding range of indoor plants and some of them claim to be

Ventilation Systems vs Dehumidifiers: What's the Difference?
21 May 2019
When we think of a comfortable home, we imagine a nice, warm, dry house free of mould and mildew caused by moist, condensed air.

Healthy air and a healthy mind are more related than people think. It’s important for both our mental and physical health that we live in homes that are properly ventilated, to create a safe environment for our families. Here we explain how a healthy home through proper ventilation can lead to a healthier and happier
A whole house ventilation system ventilates every room in the house, eliminating stale air and keeping the air fresh to maintain a healthy environment. Ventilation systems are important to have in our homes, but many people think that this means installing range hoods in the kitchen and extractor fans in the bathroom. This simply isn’t
Below are the typical/average measurements for room spaces in a house.
To calculate the cubic volume multiply the floor area by the ceiling height (eg. 2.40m)

The game-changing Unovent® ventilation system was invented when a man was looking for a less expensive, longer lasting and cheaper running ventilation for his own home.
Being an engineer, John Wadsworth had an understanding of moisture control, air management, electronics and control systems. He was puzzled why other brands used a large,
Perhaps the greatest advantage of an Unovent® ventilation system is its simplicity.
Many other ventilation systems are either:
Uncontrolled - they simply take air from a ceiling space and blow it into the building without consideration to temperature or humidity; or
Manually controlled- they require the home owner to set up and
According to the World Health Organisation, polluted urban air kills over 3 million people every year. But now there’s a scientifically proven, sustainable filter technology that traps particles and bacteria. Introducing HELIX™ Filter Media, manufactured using pure New Zealand wool.

Autumn is often the nicest time of the year. Here in New Zealand it’s usually warm with little rain or wind. It’s the most popular time of the year for outdoor pursuits – meaning many people are away from their homes for long periods.
Empty unventilated homes are prone to heating up during the day as a result of solar gain
Warm moist weather is a difficult time for householders’ conscious of maintaining a healthy home. The daily temperatures make it attractive to open windows to cool the house – but the air entering the house may be moist, creating damp conditions perfect for mould and moisture to flourish.
The rule of thumb is simple … if the
There are many websites advising all houses should have ventilation in the roof space. Most of these sites are American or European and much of the information is of little value here in New Zealand. However, the one common theme that is relevant in NZ is that every house DOES need adequate ventilation into the roof/ceiling space.
Here at Unovent we had a situation where a ventilation system simply didn't work. That didn't make sense as the Unovent system (or any other ventilation system) is simply a way of moving stale air out of a house and replacing it with fresh air ... just like opening the windows on a nice day. The elimination of moisture in the home is
Few people stop to consider what happens to the moisture in towels, clothes or other damp objects (pets) that are dried inside the house.
Many people dry clothes indoors during the winter, on the radiators, in front of the fire or just on racks. But drying clothes indoors increases the amount of moisture in the air by 30 percent or more. This
Insulation is very important for a healthy home. Insulation makes heating more effective and much less expensive. Every home should be insulated.
Ventilation is also important. Fresh, dry air can be heated more efficiently and economically than stale, moist air that is created in the home by normal living.
Heating is one of the 3 elements for a
Moisture refers to the presence of a liquid, especially water. Small amounts of water may be found, for example, in the air (humidity), in foods, and in various commercial products. Moisture also refers to the amount of water vapour present in the air. This is the moisture that we are interested in dealing with to create a healthy home.
Most Unovent competitors are telling their potential customers that our Unovent must be inferior ... it must be because it costs so much less. We can imagine they are worried as many people are discovering they can have a Home Ventilation system that works perfectly and cost much less to run at half the price. Worried competitors make us happy,
The majority of people in New Zealand live in unhealthy homes that may be shortening their lifespans. This results from research by credible organisations that have researched the subject. Children’s Commissioner Russell Wills says, “It is intolerable that we have 42,000 hospital admissions and 15 deaths a year for children with
EECA Energywise states around 30 per cent of homes are damp and many houses in New Zealand have mould. Some other authorities suggest that figure is much higher in many parts of the country. It’s not just old homes or rental properties that suffer. Even new, well-insulated homes are often inadequately ventilated and soon develop moulds and
Dampness in our homes - there's more than you think!

An Otago University study recently found a family of four can produce 34 litres of moisture a day through everyday tasks? That’s astonishing and above most people's expectation. Imagine taking 16 x 2 litre milk containers, filling them with water and spilling it all over your home.
Moisture in the home is introduced by cooking,

A number of Unovent ducted solution competitors are advising their potential customers that the Unovent system has inadequate airflow, both for the homes and in comparison to their own competing system. They are misleading those who genuinely wish to have a healthy home at an affordable price with low running costs.
The issue is actually about a
As homes become more insulated and sealed to be energy efficient, few have given consideration to those that have solid fuel and gas fireplaces. To burn effectively a fire needs a source of fresh air (oxygen) to provide combustion.
Some fires have a built in air intake from outside to provide fresh air. However, it’s likely the
For many years, home ventilation systems were left running 24/7 (which was a very expensive ventilation solution) or turned on and when the home owner became conscious of moisture (eg. weeping windows).
As neither of these arrangements was suitable, ventilation manufacturers developed control systems. These tend to be based on preselected times
Recently it was reported in the news media that a home in Gore suffered fire damage as a result of the ventilation system installed in the ceiling space.

It also offers a number of good tips to be rid
The El Niño weather conditions during past weeks have created (wet) sticky and humid temperatures over most of the country. It's interesting to reflect on the effect this has inside our homes and how it relates to home ventilation systems.
Our homes are surrounded by air (outside) which is always eventually the source of air brought

Anyone in a Kiwi business will be aware that New Zealand is a long thin country – with many inherent problems for both business and their customers.

Many people suffer from pollen allergy – it’s suggested one third of the population suffers from Seasonal Allergic Rhino Conjunctivitis – more commonly known as hay fever. There are numerous plants that create hay fever symptoms and most are blown around the country by the wind.
