They promise to remove pollution, dust and allergens like pollen from the air in your home, but do air purifiers work, and what does an air filter do? With this simple guide, you can weigh up the benefits of having an air purifier in your home and consider easy alternatives, too.

What does an air purifier do? A simple explanation

Ever found yourself asking, “what is an air purifier?” or “how do air purifiers work?” Well, air purifiers actually use a very simple process.

Using a system of fans, an air purifier will pull the air from around your home inside and pass it through a series of filters. These filters are designed to remove particles such as dust, animal dander, and bacteria. The clean air is then circulated back into the room, keeping the air in your home clean and healthy.

Are air purifiers worth it? A breakdown of whether you need an air purifier

Getting an air purifier can be a bit of an investment, so you may want to check whether it’s worth it. Here are a few reasons why you may need an air purifier as well as some budget-friendly alternatives:

  • Do you or a family member suffer from allergies? Air purifiers help your family to breathe clean air and remove many allergens that circulate in the air inside your home.
  • Ever found your house smelling of a meal you made days ago? Air purifiers not only clean the air but help to remove odours, including burnt food and more.
  • Got an open fire at home? An open fire makes the house feel warm and homely, but  an air purifier will help trap and remove smoke before it ends up in the walls and furniture.
  • All homes accumulate dust. While regular vacuuming and dusting are a great alternative to keep dust at bay, air purifiers help to remove dust from the air, keeping your home cleaner for longer. Check out our article on how to prevent dust allergies for more tips.

  • Need a budget-friendly alternative? Daily dusting and cleaning will go a long way to keeping your air fresh and clean. You could also try out air-purifying plants to clean your air and decorate your home at the same time – a win-win!
