If you have asthma you know that even to breathe is an amazing feat. People take breathing for granted. But if they have asthma, they know how amazing it feels to feel fresh air going deep into their lung.
For most sufferers, daily outdoor activities are a serious no, no. Staying indoor is the best protection from smoke, dust, pollen and other harmful floating particles.
But there’s a slight problem with that idea. You see, the air in your home could be worse than outdoor. Well, I didn’t say that. The United States Environmental Protection Agency (EPA) is the one making that claim.
That is why many sufferers are now turning to modern technologies to help save their lives. One such technology is called air purifier.
If you’re thinking of shopping for one, let’s see 4 basic types of air purifier you could find on the shelves of your neighborhood supermarket today.
1. Electrostatic Air Cleaners
Well, at least that’s what the makers would call it – air cleaners. If you open one of these machines, you will see a long wire or plates in it. Here’s how it works. When air runs through the wire or plate, dirty air gets charged. The charged dust will then cling to the wall or washable filter in the machine.
In theory it’s sufficient. But in reality, it only gets rid less than 50% of what’s on air. Secondly, that sort of operation could create a type of gas called ozone. While it is good up in the air, you certainly do not want it in your bedroom because it is highly toxic.
They are usually much cheaper and smaller than most hospital-grade air purifiers. Some could be as big as your toaster. The pamphlet attached to the machine and the late night infomercials by sexy sales lady will tell you that ozone kills bacteria, viruses and other harmful particles unseen to your eyes. But it omits one important fact. It could also kill you.
