How to Choose the Right Air Ioniser for Your Home

Your Guide to buying the best Air Ioniser


An air ioniser is a device that produces and releases negative ions into the air. These ions help to purify the air by removing allergens such as dust, pollen, and bacteria, as well as reducing pet dander and reducing odours. This buying guide will help you determine what type of air ioniser is best for you and your home, as well as the features to consider when purchasing one. We'll also discuss the benefits of using an air ioniser and how to maintain and care for it in order to get the longest life out of your device.

Key features

  1. Air Quality – Look for air ionisers that are able to remove dust, pollen, pet dander, smoke, and other allergens from the air. You'll also want one that can filter out mold spores, bacteria, and other pollutants.
  2. Size and Portability – Choose an air ioniser that is either wall-mounted or portable, depending on how much space you have available. Consider the size and portability of the unit, as well as any features that make it easier to move from one place to another.
  3. Noise Level – Check to see how loud the air ioniser is prior to purchasing it. Some units produce a lot of noise, and if you want to use it in a bedroom or other quiet area, it may be best to choose a quieter model.
  4. Energy Efficiency – Look for an air ioniser with an Energy Star rating, as this will help reduce your energy costs. Also make sure to consider the wattage of the unit, as this can also affect the amount of energy used.
  5. Maintenance and Upkeep – Make sure to check out the maintenance and upkeep requirements of the air ioniser before buying it. Some units require frequent filter changes, while others may not require any maintenance at all.
  6. Cost – Air ionisers come in a range of prices, and it's important to consider your budget when shopping. Make sure to factor in any additional costs for filters, replacement parts, and other maintenance items.

Common questions

  1. What is an Air Ioniser? An air ioniser is an electrical device that helps to purify the air in a room or enclosed space by producing negative ions. These negatively charged ions bind to airborne particles such as dust, pollen, and smoke and neutralise them, removing them from the air.
  2. What are the benefits of using an Air Ioniser? An air ioniser helps to improve the air quality in a room or enclosed space by removing airborne particles such as dust, pollen, and smoke. It also helps to reduce the amount of allergens and bacteria in the air, reducing the risk of allergy and infection.
  3. Are Air Ionisers safe to use? Yes, air ionisers are generally safe to use. They produce a low level of ozone which can be harmful if inhaled in large amounts, so it is important to ensure the product is properly used and maintained.
  4. What features should I look for when buying an Air Ioniser? When buying an air ioniser, it is important to consider the size of the room or enclosed space you will be using it in, as this will affect the size and power of the device you will need.

The best type of air ioniser for your needs will depend on the size of the room or enclosed space you will be using it in, as well as your budget and the features you are looking for. Generally, it is best to opt for a model with a HEPA filter and adjustable settings for maximum effectiveness and convenience.


Recent research suggests that air ionisers may have some medical benefits. In fact, it has been observed that when air ionisers are used, respiratory illness and asthma symptoms are reduced in people who are exposed to them. This is likely due to the fact that air ionisers can neutralise harmful bacteria and viruses in the air, which can otherwise lead to respiratory problems. A study published in the International Journal of Environmental Research and Public Health also found that air ionisers reduced the levels of certain pollutants in indoor air, such as formaldehyde, nitrogen dioxide, and volatile organic compounds. This could be of great benefit to those who suffer from allergies or respiratory illnesses. Source:
