What makes the best air purifier for bushfire smoke removal?
With more than 100 bushfires burning in Australia, and Sydney experiencing worse air quality than Beijing and New Delhi, millions of Australians are suffering from the harmful effects of smoke inhalation, which can be worse than second-hand cigarette smoke.
This ongoing problem is posing serious risks of short-term and long-term health effects, particularly for pregnant woman and children with asthma. 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. There is also the smoke vapour, which consists of gases including carbon monoxide, carbon dioxide, nitrogen oxides and volatile organic compounds.
If you are looking for an air purifier to filter bushfire smoke from the air in your home or workplace, it is important to understand the basics of how an air purifier filters particles and smoke.
The majority of air purifiers found in appliance stores are ineffective against smoke because they contain very little activated carbon, usually only a pad, which is a few millimeters thick.
Activated carbon works like a sponge, it adsorbs the smoke from the airstream. It is used in gas masks by firefighters and in professional grade gas respirators. Too little activated carbon, and the smoke will pass straight through.
The more activated carbon in the filter, the more contact time with the smoke, and the better it will be removed from the air; it will also last significantly longer.
At InovaAir, we manufacture our filters with the largest amount of activated carbon filters on the market. Our E8 model includes 2.5kgs and the E20 series contains 6kgs, which makes them highly effective in smoke removal. 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.
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.
If you choose a cheaper system without adequate activated carbon in the filter, you will end up paying for it in the long run – both in terms of the impact on your health, and when you have to buy another system that actually does the job you need it to.
Read the product specifications and find out exactly how much activated carbon the system contains before making a purchasing decision.
