Are you wondering how air purifiers work and whether it’s worth having one in your home? You’re in the right place!


What is an air purifier?
From dust, pollen and pet dander to smoke and cooking odours, a wide range of everyday pollutants can make their way into the air in your home. Although the air quality inside your home is unlikely to reach dangerous levels, poor air quality could cause trouble if you suffer from asthma or allergies.

Air purifiers are designed to remove those potentially harmful nasties from the air and circulate clean air back into your home, giving you confidence that the air you are breathing is as clean as possible.


How do air purifiers work?
There are several different types of air purifier – the most common type used in domestic homes combines a fan with one or more filters. The fan draws in air, the filters purify it by removing and trapping particles, then fans circulate the clean air back into your room.

Air purifiers that use HEPA filters or have multiple filters layered together can be more effective than those with a single filter. High efficiency filters remove even the smallest particles.


What are the benefits of air purifiers?
Cleaner air in your home can have a wide range of benefits. An air purifier may help if you suffer from allergies or asthma, removing the pollen that triggers symptoms. Pollen can enter your home through windows, doors and even on your clothes – so an air purifier can be a real help during allergy season!

Air purifiers can also remove mould spores, which can be helpful if your air is particularly humid, to help prevent mould growth on food and surfaces Similarly, high performance filters can also trap bacteria and viruses.

They are often popular with pet owners, because those with special carbon filters can filter out airborne pet dander and odours. Some people also feel that they sleep better when the air quality is high – just make sure to choose a quiet air purifier with a screen that can be turned off for overnight operation!

Finally, as they remove pollutants from the air – such as odours or smoke – having an air purifier can also simply make for a more pleasant living environment.
