An air purifier is the most effective way to clean the air in your home, so they’re perfect for those with allergies and sensitive skin. This is because they trap allergens like pollen and dust mites and indoor pollutants, like cooking gas fumes, plug in diffusers, sprays and cleaning products. Air purifiers that have HEPA filters capture up to 99.95% of allergens, so the air in your house is free of any harmful bacteria and you can breathe easier. In our guide, we’ll tell you how an air purifier works and how you can spot a true HEPA product.
Air purifiers force air through a fine mesh filter to capture allergens like dust mites and pollen. They then release clean, pure air back into the room. Models with HEPA filters are even more effective at cleaning the air, as the mesh is even finer and traps 99.95% of pollutants, so they’re far better at protecting your family if they suffer from hay fever or sensitive skin.
For a filter to be classed as HEPA, filters need to trap at least 99.95% of particles from the air that are as small as 0.3 microns. A micron is one-millionth of a meter, so this means they will capture those nasty little irritants you can’t see, like dust mites, pollen, mould and gases to keep your house clean and fresh.
