FAQs
The Airora Home
WHAT MAKES AIRORA HOME DIFFERENT FROM OTHER AIR PURIFIERS ?
Unlike filter-based air purifiers, Airora treats all of the air in a room, not just the air that passes through the device. And Airora is the only air purifier / sanitiser which creates a Hydroxyl Cascade to destroy or neutralise all types of pathogens harmful to humans, as well as allergens, mould spores, gaseous pollutants and irritants, odours and germs.
Hydroxyl radicals occur naturally outside but not inside. They kill all harmful bacteria and viruses, including Coronaviruses, Colds, Flu, MRSA, C-difficile and Norovirus - the UK's Health Protection Agency measured a 99.9999% kill of a test virus in less than 5 minutes!
And the Hydroxyl Cascade doesn’t just sanitise the air in the room, it also destroys harmful bacteria and viruses on surfaces and contents within the room.
No other air purifier / sanitiser comes close!

AIR FILTERS ARE OFTEN SO NOISY, HOW DID YOU MAKE AIRORA HOME SO QUIET ?
Because we directly clean all of the air in the room, not just that which goes through the device, Airora isn't classed as an air filter and we don't need to employ a powerful but noisy fan to try and force the air in the room through the device.
WHY IS THE AIRORA HOME PYRAMID SHAPED ?
Why not? But seriously - the shape is dictated by the underlying technology - it allows a large diameter fan in the base which can run relatively slowly and quietly, and it can't fall over! Plus, we think it looks pretty cool!
WHAT ARE AIRORA’s CADR AND FILTER EFFECTIVENESS RATINGS ?
The Clean Air Delivery Rate (CADR) and filter % effectiveness measures were developed in an attempt to compare the effectiveness of traditional air filtration devices, as the rate at which air passes through them and the percentage of particulates captured within them were thought to have a bearing on their performance (however limited).
As the Airora air purifier doesn’t clean the air in your room by passing it through a filter, but cleans the air in-situ by creating a hydroxyl cascade which automatically and completely spreads throughout the room, these measures have no bearing on its effectiveness.

DOES AIRORA HOME REQUIRE REGULAR 'REFILLS' ?
Yes, Airora Home uses what is technically termed an "essential oil", distilled from plants and flowers, as part of our unique process to recreate nature's atmospheric chemistry. "Essential oils" are everywhere in the air we breathe outside - remember the song 'The Blue Ridge Mountains of Virginia'? - the blue colour is the light reflecting on "essential oils" given off by the pine trees!
This ingredient comes in low cost easy to install cartridges, and with Airora Home your first six month's supply is provided with each device purchased. You can purchase packets of additional cartridges or simply ask us to send you 12 months supply automatically each year.

Does Airora HOME require regular maintenance / changes of filter?
An Airora air purifier has only one moving part, which is a low speed fan, with a long MTBF (Mean Time Between Failure) which requires no routine maintenance.
An Airora air purifier / sanitiser is not a filter and so there is no reduction in efficiency as a filter becomes contaminated, nor indeed is there a filter to replace from time to time.
There is very little to ‘go wrong’ in the machine, indeed in its latest version the Airora Home’s original UV lamp has been replaced by long life LEDs.
However, Airora does use a consumable to deliver what is technically termed an "essential oil", distilled from plants and flowers, as part of our unique process to recreate nature's atmospheric chemistry. That consumable takes various forms depending on the model.

Does an Airora HOME have complicated controls or require any training to use?
The Airora Home is very simple to use, with no complicated controls or settings, just an on/off switch!

WHAT STEPS SHOULD I TAKE TO REDUCE AIR CONTAMINATION IN THE FIRST PLACE ?
Before buying an air cleaner you should consider taking common sense steps to minimise the air pollution in your home. An Airora air cleaner will really help, but as always, prevention is better!

HOW MANY AIRORA DEVICES DO I NEED ?
Airora Home is designed to be used in a normal home environment and is effective in a room size up to 3000 cubic ft (100 cum), that is a typical 20’x20’ (6mx6m) room.
If your room is larger than 3000 cu ft , you can safely use multiple devices and if it is substantially less than 3000 cu ft, don’t worry, it is perfectly safe, and very effective, in smaller rooms also.

HOW DO I MAKE THE BEST USE OF MY AIRORA air purifier ?
If your objective is related to a breathing or allergy problem, we suggest that you start by installing an Airora Home in your bedroom and from there those rooms that you spend substantial amounts of time in.
An Airora purifier is great for the kitchen or kitchen diner as it is highly effective against smells arising from cooking and disposal bins, as well as air pollutants caused by cooking. If you have a pet then it will keep the rooms the pet uses clean and fresh!
Where the source of the pollution is clear, such as smoking or drains or damp smells, then Airoras can be used strategically to address the issue.

HOW DOES AIRORA FEEL ?
Lovely!
SHOULD I CONTINUE TO ‘SHUT OUT’ POLLENS?
You should continue to take all reasonable steps to prevent pollens getting into your house, particularly at night. Prevention is always better than cure!
Hydroxyls are very small (just two atoms!) which enables them to get inside germs and kill them almost instantaneously. However, because they are tiny compared to pollens it takes a while for them to so change the pollen’s surface so that your immune system doesn’t recognise and react to them as allergens.
As pollens generally fall to the ground quickly, hydroxyls generally have a good amount of time to neutralise them before they are disturbed again. However, at night you should close your bedroom window to avoid what are known as 'pollen showers' which occur in the middle of a hot night and which may take Airora a while to neutralise. You can find out more about pollen showers here.

SHOULD I LEAVE THE AIRORA HOME running conTINUOUSLY ?
Yes, because the air in a room is constantly changing and being re-contaminated by air and people movement.
However, because we directly clean all of the air in the room, not just that which goes through the device, Airora isn't classed as an air filter and we don't need to employ a powerful but noisy fan to try and force the air in the room through the device.

Are there any in-use safety issues?
The Airora Home is safe to use in any room and in any position (the user manual provides guidance on most effective positioning).
CAN YOU GUARANTEE THE AIR IN MY HOME WILL BE POLLUTION AND GERM FREE ?
Airora Home is designed for a 'normal' home environment and room not exceeding 3000 cubic ft (100 cum), that is a typical 20’x20’ (6mx6m) room.
Within that space the various types of pollution, as described (and excluding CO2 - Carbon Dioxide), will be neutralised and made safe at varying rates.
However, factors such as embedded sources of germs/smells, extreme levels of pollution, or the air in the room changing unusually quickly, may create an atmosphere that the Airora device cannot keep as clean as it would otherwise do.
Factors such as those described above, which are outside of our control, mean that we cannot guarantee that the air in your home will be pollution and germ free. Similarly, we cannot guarantee that you will not catch infections or diseases where an Airora air purifier is present, not least because they can be transmitted other than through the air.

The Science
IS AIRORA COMPLETELY SAFE ?
Absolutely. Hydroxyl radicals are a natural part of the outside environment, often occurring in outdoor air at higher densities than are generated by Airora. Humans, like all animals, insects and even normal skin flora, evolved alongside hydroxyls, resulting in our skin and mucosal membranes providing a protective barrier that prevents hydroxyls from entering our blood stream or tissues within our body.
Hydroxyl generation has been approved by the FDA as a safe air cleaning technology.
Our technology has been tested at leading independent laboratories worldwide and been shown to be both highly effective and entirely safe.

HAVE YOUR SCIENTIFIC CLAIMS BEEN INDEPENDENTLY VERIFIED ?
Yes they have; you can find out about our development programme and independent test results on our Verification page.
CAN THE INDOOR ENVIRONMENT BE 'TOO CLEAN' ?
There have been concerns that protecting children from all contact with bacteria and viruses (germs) results in them failing to develop natural resistance ("passive immunity") to infection.
Bacteria and viruses killed by Airora's Hydroxyl Cascade retain what scientists call their 'antigen signature'. That means that even though they can't harm you, they can still induce passive immunity.

DOES AIRORA EMIT OZONE ?
We're glad you asked that, because even moderate levels of ozone can be a lung irritant, and some types of air purifier do increase the level of ozone in a room.
Although the Airora Home and Professional do emit tiny amounts of ozone, the amounts fall way below even the toughest safety regulations anywhere in the world.
Plus, the Hydroxyl Cascade and plant oil react with and break down any ozone they encounter, leaving less ozone in the room than before!

HOW QUICKLY DOES THE HYDROXYL CASCADE CLEAN THE AIR ?
The Hydroxyl Cascade reaches every corner of the room and every exposed surface in seconds by molecular diffusion. Some pollution, such as germs and viruses, are killed instantly on contact with hydroxyls. Others, such as odours and VOCs , take a little longer (but still very fast) as the hydroxyls break them down to ever shorter chain molecules and eventually into carbon dioxide.
Physically large contaminants, such as pollens, take longer to neutralise as hydroxyls are very small indeed and multiple interactions are often required. Fortunately, these heavier contaminants rapidly drop onto a surface where the hydroxyls continue the process of neutralising them before they are disturbed and made airborne again.

AREN'T 'FREE RADICALS' BAD FOR MY HEALTH?
There are many types of 'radical', not just the hydroxyl radical, and collectively they are sometimes termed 'free radicals'. Concerns regarding the potential damage arising from excessive ‘free radicals’ in our bodies have been a hot topic of debate for some years.
However, hydroxyl radicals are completely safe, often occurring naturally in outdoor air at higher densities than generated by Airora. Humans, like all animals, evolved alongside them, resulting in our skin and mucosal membranes providing a protective barrier keeping them from entering our blood stream or tissues within our body.

DOES AIRORA'S TECHNOLOGY WORK IN ALL AMBIENT ENVIRONMENTAL CONDITIONS?
An Airora device will work reliably and effectively within a wide temperature band and in conditions of both high and low internal humidity.
