Air purifier guide
What is an air purifier?
An air purifier is a device that makes the air inside your home healthier to breathe. It does this by trapping the tiny, airborne particles that cause allergies, odours and irritation, while letting the clean air pass through.
How does an air purifier work?
Most air purifiers have a fan that sucks air from around the room and pushes it through a filtration system. From here, the air is cleansed of pollutants and odours before being released back into the room.
Benefits of air purifiers
There are many advantages of having an air purifier. For one, they keep nasty allergens like dust mites and pollen out of your home’s air flow. Another plus is that they banish unpleasant odours such as pet smells, cigarette smoke and cooking fumes.
Types of air purifiers
How an air purifier filters the air inside your home varies from model to model. Here’s a brief round-up of the main types available.
HEPA air purifier
Air purifiers with HEPA filters are highly effective at catching microscopic particles that cause allergies and trigger asthma.
Ionic air purifier
This type of air purifier emits electrically charged ions which attract and attach on to dust and allergens and remove them from the air.
Carbon air purifier
If you want to remove odours, smoke and vapours from your indoor air then choose an air purifier with a carbon filter.
UV air purifier
These air purifiers contain an Ultra Violet (UV) light that breaks down and destroys floating bacteria and airborne viruses.
Air purifiers vs humidifiers
Although both air purifiers and humidifiers help improve the quality of indoor air, there are notable differences between the two. Humidifiers make the air around you cleaner and fresher by emitting water vapour into the air. They, however don’t cleanse the air of impurities like air purifiers do.
Air purifier features
Many types of air purifiers are available, from basic models to more advanced ones with multiple features. Here are some key features to look for when choosing an air purifier.
What size air purifier do I need?
In order to know what kind of air purifier is best for you, you'll need to work out the square footage of the room in which it’s being placed. Typically, desktop and mini tower models are best for small bedrooms, nurseries, and rooms up to 155 square feet. For living rooms and large bedrooms, opt for a tower or console model with a room size coverage of over 300 square feet.
