Allergens may take on many guises and for the most part are invisible to the human eye. Sometimes the only indication of their presence is a cough or slight wheezing. Believe it or not it is difficult to concretely distinguish between bronchial asthma and chronic respiratory inflammation caused by living with poor IAQ (Indoor Air Quality). The two are inextricably linked. Asthma is a combination of genetic predisposition and exposure to environmental factors.

There have been many studies linking the development of adult asthma to such environmental factors. These causes are in fact a long term exposure to the very same triggers that exasperate symptoms in someone who has already been diagnosed.

Regardless of severity of symptoms it is important to minimise exposure to the triggers on a long term basis. The problem is that the triggers are present in every home in one way or another. They range from pet hair, to dust collecting behind furniture, to mite excrement and mold spores. And that’s just indoors! Pollen, sand dust and pollution can make their way into your home from the outside.

When you are susceptible to these triggers it is important to identify them as soon as possible and to deal with them on a long term basis.


Using an air purifier at home can increase the air quality at home tenfold. A high grade HEPA filter normally filters out around 99.97% of particulate matter. This includes pollen, dust mite excrement and mold spores. The important thing to remember is to choose a powerful purifier that can perform several complete air changes in one hour. This means all of the allergens present in the air will collect within the filter. The HEPA filter layer can then be replaced with a fresh one. Running such a filtration system as often as possible has been medically proven to reduce respiratory inflammation.

A quality air purifier will have several other filtration layers within. For example, to deal with complex chemical pollutants and odors, a charcoal layer is used. This clever filter uses Van der Waals molecular forces to permanently eliminate complex allergens. Again, a powerful air flow will capture most pollutants inside the filter.

An intelligent air purifier will use a microcomputer sensor to run the machine in accordance with air quality. Essentially it purifies the air in real time. It adjusts air flow and filtration stages to suit the air quality.

Air purifiers are by no means a cure for asthma, but they do go some way to ensuring a healthy environment at home. They are definitely a good choice people with respiratory conditions.

Over 15 years ago, the original creators of Odair set out to make systems which naturally eliminate odours and pathogenic infestations in large scale horticultural setups and be kinder to the environment. It was a huge success. To this day Odair machines are still being used around the world to cleanse and purify organically; without the use of any chemicals at all.

They have teamed up with Dr Adam Bains from The University of Leeds and his partners from the highly decorated Oxford University. Pooling these vast resources, together they created a totally unique four stage filtration system for use in just about any home on our planet! Now ranked in the top 5 in the world, they bring their unique air purifier – the Venti

“Venti filters the air in your home, breaks down harmful VOCs such as benzene and eliminates allergens such as mold spores and pollen. On top of all this it invigorates and re-energizes your air, in the same way that nature does with enormous charge fields up in the clouds. True to our company ethos, we do all this naturally, making your home air crisp, fresh and healthy.”
