All About Ionisers
AIR PURIFIERSFEATURED
Bringing a Breath of Fresh Air Indoors
Ever craved that invigorating feeling you get after a walk by the ocean or a hike in the mountains? Those clean, crisp breaths can be attributed, in part, to the abundance of negative ions present in natural environments. Air ionisers aim to recreate this effect indoors, promising a range of benefits for your home environment. But how do they work, and are they truly effective?
In this guide
How Air Ionisers Work
At their core, air ionisers are devices that generate negative ions. These ions are air molecules that have gained an extra electron, giving them a negative electrical charge. Air ionisers achieve this feat through various methods, most commonly using high voltage to create an electrical field. As air passes through this field, some molecules become energised and capture an extra electron, transforming into negative ions.
These newly minted negative ions then go on a mission to improve your indoor air quality. They attract airborne particles like dust, pollen, pet dander, and even some bacteria and viruses. These particles carry a positive or neutral charge, and the opposite charges attract. Once attached to the ions, the weighted-down particles can no longer freely float in the air. This effectively reduces the number of airborne irritants, making it easier to breathe.
There are two main types of air ionisers:
Unipolar Ionisers: These generate primarily negative ions, which is the type most commonly used in home air purifiers.
Bipolar Ionisers: These emit both positive and negative ions, aiming to mimic the natural balance found in outdoor air.

Benefits of Air Ionisers for Your Home
While air ionisers don't physically remove pollutants from the air, the way they interact with airborne particles can offer several potential benefits for your home environment:
Improved Air Quality: By clumping together airborne contaminants, ionisers can make a noticeable difference in the number of dust particles and allergens floating around. This can be particularly helpful for those suffering from allergies and asthma.
Reduced Odors: Negative ions can help neutralise some airborne odors by attaching to odor molecules and rendering them less potent. This can be beneficial for managing pet donders, cooking smells, or cigarette smoke.
Enhanced Mood: Some studies suggest that negative ions may have a positive impact on mood and well-being. There's a growing body of research exploring the link between negative ions and increased serotonin levels, which can elevate mood and reduce stress.
Reduced Static Electricity: Air ionisers can help reduce static electricity by balancing the positive and negative ions in the air. This can be beneficial in reducing the frequency of static shocks and helping to prevent dust from clinging to surfaces.

Things to Consider Before Buying an Air Ioniser
While air ionisers offer some potential benefits, it's important to be aware of some limitations and potential drawbacks:
Limited Removal of Pollutants: Air ionisers primarily address airborne particles, not gaseous pollutants like volatile organic compounds (VOCs). For a more comprehensive air purification solution, consider an air purifier with a HEPA filter.
Maintenance Needs: Some air ionisers produce ozone as a byproduct. While low levels of ozone can be beneficial, high concentrations can irritate the lungs. Regularly cleaning the ioniser and following manufacturer recommendations for ozone production can help mitigate this concern.
Settling of Particles: As mentioned earlier, ionisers don't remove particles from the air, they simply weigh them down with negative ions. These particles can then settle on surfaces, requiring more frequent dusting and cleaning.
Limited Research: The research on the long-term health effects of air ionisers is still ongoing. While some studies suggest benefits, more research is needed to confirm the extent and consistency of these effects.

Conclusion: A Breath of Fresh Air, But Not a Miracle Cure
Air ionisers can be a valuable tool for improving indoor air quality by reducing airborne allergens, dust, and some odors. However, it's important to understand that they are not a one-size-fits-all solution for air purification. For a more comprehensive approach, consider combining an air ioniser with a HEPA filter-based air purifier. By understanding the limitations and benefits of air ionisers, you can make an informed decision about whether they can contribute to a healthier and more refreshing home environment.
