Air Purifiers : Why You Need Them

You can’t see it, but you can smell it – even feel it. Indoor pollution is often overlooked because of the focus on outdoor pollution, but it’s there alright. Some of it has been there since our cave-dwelling days. Some of it entered in recent times. And some of it is, and always has been, inevitable in the form of bacteria and mold from natural environments. All of it combined, however, makes indoor air pollution a serious threat that causes stroke and cancer, leading to 3.8 million deaths a year worldwide.

The EPA estimates that indoor air is two to five times dirtier than outdoor air – sometimes, up to a 100 times dirtier.

It sounds strange, right? But it makes sense when you realise that indoor environments have less ventilation than outdoor environments, making them more susceptible to trapping pollutants.

That’s where – and why – air purifiers come in.

Air purifiers put the air in your home through a series of filters that remove harmful air particles including dust, pollen, and bacteria, while circulating purified air in the room. This ensures you can breathe clean air – indoors, if not outdoors.

Air purifiers have several other benefits. Let’s explore them briefly.

  • They’ll get rid of bad smells. This is especially helpful for people who love to cook, er, strong flavours and for people who end up burning pretty much any flavour.
  • They trap airborne allergens released by the fluffy bundle of fur you adore. Many people are allergic to pet hair and dander, and air purifiers prevent these allergens from circulating inside the house. Oh yeah, and the previous point would have told you that they can also get rid of the wet dog smell. Which basically means that if you thought you couldn’t love your pet anymore, you were wrong.
  • They’ll keep you healthier. Air purifiers can remove up to 99 per cent of airborne bacteria. That ranges from pollen and mold spores to your five year old’s sniffly nose germs.
  • They trap second-hand smoke, whether it’s from a cosy fireplace or a cigarette, which means they can help your lung health in the long run.
  • They reduce carbon dioxide levels in your home and by doing so, mitigate many side effects of the gas.
  • They’re convenient and available in a bunch of sizes with a variety of features, so you will be able to keep the air fresh in every room in the house.

A quick word on HEPA filters

HEPA (High Efficiency Particulate Arrestance) filters are the gold standard for air filters. An air filter classifies as a HEPA if it removes at least 99.97 per cent of particles (0.3 microns or larger) from the air. There are many different kinds of HEPA filters available and a quick internet search will help you choose the right one.
