Becoming modern from our origins has been marked by numerous advances that are now considered commonplace. For example electricity, better sanitation, and faster transportation have allowed for an improved way of life with a limited downside.

One area that is widely overlooked as a massive change from our beginnings, is shelter. Over time we have come to demand more from our living spaces. We want them bigger, more comfortable, in the most desired locations in relation to others, and to also express an individual about us.

In conjunction with this emphasis is the fact we seemly have a deaf emotional attachment to our dwellings. If it is true that there is such an attachment, it is also very reasonably true that we are spending far more time indoors not getting fresh (grated in some cities, not so fresh) outdoor air.

Add in the office, restaurants, the supermarket and the mall, plus the time spent in our car, and we are more of an indoor people than ever before. The conventional wisdom is that there is no breathable fresh air in these indoor structures. Venture into any major city where there are long-established buildings. Chances are they will not have working windows. The downside of being indoors more is definitely the fact of compressed and stale air.

Room air purification systems are an increasingly popular option for people who are concerned about the impurities and long-term dangers of enclosed air that is breathed over and over again. There are pollens, allergens, mold spores, smoke residue, carbon dioxide, animal odors, and many times trace carcinogens in our stagnant indoor air. The short and long-term medical issues associated with poor air are becoming clearer and more frightening as research advances.

People who are exposed to mold spores, excessive carbon dioxide, second-hand smoke, or smoke residue, report feelings of gagging during sleep, shortness of breath, and general discomfort while simply lounging in front of the TV. Air purification systems offer a way for a person to make the indoor environment more like the outdoor, by decreasing the percentage of impurities in the total whole of the air.

Most of these systems are simply plug-in models with the ability to take in air, filter it, and re-release the air for breathing. Until fairly recently, they were boxy and looked like a piece of cumbersome medical equipment. The newer models are sleeker, more compact, and hide in the room layout much easier.

A buyer should seek to add a purifier that provides “full-circulation capability”. This simply means the machine utilizes technology to grab and purify air room-wide rather than right nearby.
