It's a little-known fact that the air as part of your home is dirtier than the air outside it. No matter what you do how many windows you open or whatever this may often be the case. This really is true mainly because of the amount of hiding places your home has for dust and other particles, while at the same time having a limited amount of escape routes for the particles. 

You might wish to consider getting an air cleanser, to go a way towards alleviating this problem. This will be especially useful to you if you have allergies or asthma that can be aggravated by dust or other particles such as pollen, being an air purifier can eliminate most of them from the air for you. You should definitely consider an air filter, as usually most of the contaminants in the smoke will build up in your homes air with time, making your indoor air to be breathed by it very unpleasant, if you smoke. 

Air purifiers can be found in a variety of different kinds, each in different ways. Typically the most popular filter is a kind of fibre pad that goes inside a body or housing, and can quickly eliminate 99.97% of pollutants from the air this is called a high efficiency particulate absorbing filter. But, these highly effective air cleaners can be costly, specially while they must be changed quite often at a higher cost each time. 

You may look at a cheaper filter, or an cleaner or air filter, that are terms used to describe cheap air devices, if your air is just wanted by you to be cleaner, however, not always entirely filtered. These units might only remove 99% of particles from the air, but for many users, that'll be enough. It is worth giving a to a filter first purchase the most high-priced one and before you go all-out, as you could be getting far more than you really need.
