Air Purifier FAQ

What is an air purifier?


Air purifiers effectively filter impurities and particles from the air helping to create cleaner air in the home. They are particularly useful for those who suffer from allergies and asthma.

Will an air purifier help to relieve allergy symptoms?


Absolutely! Air purifiers with a good HEPA filter would be ideal for those who suffer from allergies or asthma.

Pollen, dust mites and other allergens suspended in the air can cause real issues to respiratory health. Air purifiers work hard to eliminate these harmful particles from the air. Models featuring premium HEPA filters are capable of filtering cigarette smoke, pollen, dust, pet dander and more. They will help to eliminate bacteria and viruses from the air.

Air purifiers featuring carbon filters will absorb formaldehyde and other harmful gases which can cause skin irritations and respiratory problems. Formaldehyde can be found in many household products such as paint, insulation, composite wood products, glue and more. To remove smoke fumes you need to look for a purifier with an activated carbon filter as carbon will absorb and remove the tobacco smoke odours.

What do air purifiers filter from the air?


This depends on the model you choose. You must always pay attention to whether it is equipped with HEPA filter and the removal rate capabilities of the appliance before you decide if it is suitable for your needs.

Top of the range models are capable of filtering out the following items;

  • Pet & Human Hair
  • Bacteria & Viruses
  • Cotton Fibres
  • Tiny Particles - Wood/Paper Fibres
  • Dust
  • Pollen
  • Cigarette Smoke

Active carbon filters will absorb formaldehyde, volatile organic compounds and other harmful gases. They help to absorb cigarette odours too.

What does PM filter figure mean on an air purifier?


PM means particulate matter, also referred to as floating dust. They are essentially tiny polluting particles. These particles can be in suspension, fluid or a solid state.

The number; PM2.5 - PM1.0 - PM0.5 - PM0.3 relates to the diameter of the ‘floating dust’. For examples, PM2.5 is 100 times thinner than a human hair, 0.3 even smaller!

You cannot see these particles as they are formed as chemical reactions take place in the air. These pollutants are commonly released when using log burning fires and the like. This particulate matter can be inhaled if left in the air so it is worthwhile to look for air purifier models that are able to filter and process these contaminants.

HEPA Air Purifiers.

HEPA stands for high efficiency particulate air filter. HEPA air purifiers efficiently clean the air around them. An internal fan sucks ‘unclean’ air into the appliance and this air is passed through the filter. Some models include a carbon filter too which will help to remove odours from the room. During this filtering process allergens, dust mites, hair particles and other contaminants are collected in the filter and clean air is released back into the room.

It is really important to always check the noise levels of the machine. As they work hard to clean the air, some machines can be quite noisy. Top of the range models will be quieter making them suitable for use during the evening. More expensive machines feature sensors that will detect microscopic particles in the air. They can be set to auto mode, this means the purifier can pro-actively adjust the level of filtering based on the purity of the air for consistent, better cleaning. Machines with night mode ensure quiet operation, air is filtered with minimal noise allowing you to sleep peacefully in a clean atmosphere.

Filters will need to be replaced periodically to ensure the purifier continues to work effectively so it’s worth checking the cost of replacement filters before deciding on a model too.
