The best air purifier for bushfire smoke removal

The smoke generated by bushfires and hazard reduction burns is posing serious risks of short-term and long-term health effects, particularly for pregnant women and children with asthma and the elderly. What makes bushfire smoke so dangerous is the high concentrations of particles, ranging from large to ultra-fine.

It's the ultra-fine particles that pose the biggest threat. They can travel hundreds of kilometres and remain airborne for long periods of time. Then there is the smoke vapour, which consists of gases including carbon monoxide, carbon dioxide, nitrogen oxides and volatile organic compounds.

How do INOVA purifiers remove bushfire smoke from indoor air?

Bushfire smoke contains tiny particles, known as particulate matter (PM), that can be harmful when inhaled. These particles can be as small as 2.5 micrometres or smaller (PM2.5), which can penetrate deep into the lungs and respiratory system. 

High-efficiency particulate air (HEPA) filters, found in our air purifiers, are effective at capturing these particles, thereby reducing indoor air pollution.

CSIRO: HEPA filters improve air quality by 30-74% during bushfires

According to new research from CSIRO, Portable air purifiers fitted with high-efficiency particulate air (HEPA) filters can substantially improve indoor air quality during bushfire events. CSIRO Researchers found that HEPA filters have potential, when used appropriately, to substantially improve indoor air quality by 30–74 per cent during smoke episodes caused by prescribed burns.

Remove more smoke with a HEPA and Activated Carbon Filter

When looking at air purifiers for smoke removal, don’t make the mistake of buying a system that relies primarily on a HEPA filter, as it will only do half the job and still leave your home smelling of smoke.

It's why INOVA air purifiers have medical-grade HEPA filters and high-capacity Activated Carbon Filters. Activated carbon works like a sponge, it absorbs the smoke from the airstream. Activated carbon is what is used in gas masks for firefighters and in professional-grade gas respirators.

If an air purifier doesn’t have enough activated carbon, the smoke will pass straight through.

The largest Activated Carbon Filter on the market

At INOVA, we manufacture our filters with the largest amount of activated carbon filters on the market. Our E8 model includes 2.4kgs and the E20 series contains 6kgs, which makes them highly effective in smoke removal.

The more activated carbon in the filter, the more contact time with the smoke, and the better it will be removed from the air. The air purifier will also last significantly longer. We also protect the carbon filters with an H13 medical-grade HEPA filter, so no particles can clog the activated carbon and make it ineffective.

Five ways to protect yourself from bushfire smoke inhalation in your home.

Bushfires are inevitable in Australia. To ensure you are prepared, here are five really simple things you can do to protect you and your loved ones from the harmful effects of smoke inhalation:


Use an air purifier that has a medical-grade HEPA filter and a high-capacity activated carbon filter.


Keep all the windows and doors closed.


Avoid using exhaust fans in your bathroom, laundry, and kitchen, because this will create negative pressure and draw in smoke from outside.


If you have an air conditioner, choose the “recycle” or “recirculate” functions to prevent the smoke from coming in.


Avoid other sources of smoke pollution in the home, like cigarettes, burning candles and wood-fired stoves.
