Breathing is something that is vital to life. It is something we all do and need to do constantly to enable us to live. If you are not doing it now then I’m sorry but you cannot continue to read this, as you are dead.

This article is not about breathing though; it is about what we breathe. Well, that is obvious, air. Yep, but let us, for a minute, think about what may be in the air we breathe.

Apart from the components of air such as oxygen, which is the bit we need, the air you breathe is full of other particles and you need to think about an air purifier to filter these potentially harmful particles out of the air or in other words purify the air. I am sure you have seen sunlight coming through you windows and when you are at a certain angle you have seen dust particles floating in the air. You breathe these in unless you can use an air purifier to remove them or hopefully most of them. Its not only dust though, people and animals drop flakes of dead skin which is why you need an air purifier. Tobacco smoke produces particles of smoke, which is why you need an air purifier, and vehicles also produce particles of smoke from their engines, which is why you need an air purifier.

So what do air purifiers do? Quite simply they filter the air that you breathe near to them. They help to purify the air and remove airborne particles. There are many different types of air purifiers and these can be systems designed to purify all the air in your entire house down to small systems which work in a single room. They filter out all sorts of things such as smoke, dust and particles of dust and dead skin from your pets. Just remember though, they cannot filter out all particles but they can purify the air fairly well.

There is another type of air purifier, the HEPA type which can filter out particles down to 3 microns in size and can catch 99.9% of these particles. HEPA stands for High Efficiency Particulate Arrestance purifiers.

There are also ozone air purifiers but some people have suggested that these may not be good for you. I do not have the answer to this but until I am convinced of their usefulness, I will stick to an HEPA filter.

Before you buy your air purifier you need to make sure it suits your needs so make sure you carry out internet research and check manufacturers brochures. Whatever you decide though, there is nothing to beat having a look at one and seeing it operating before you buy. Remember, there is nothing worse than buying an air purifier only to find out it is so noisy that you cannot be in the same room when your air purifier is operating.
