With every passing year, it seems that homes are better built to keep out the effects of weather, making them more comfortable and energy efficient. But unfortunately, with that efficiency comes the problem of indoor air pollution, creating a situation where most newer homes need a home air purifier to limit the contaminants trapped inside.

When most people think about air pollution, they picture the brown skies hanging over a metropolitan area on stagnant days, or perhaps images of industrial smoke stacks spewing out clouds of airborne waste may come to mind. But generally speaking, people don't realize that the air inside of their homes is anywhere from five to twenty times as dirty and polluted as the air just outside their front door.

Once you put the fact of the unexpected level of indoor air contamination together with the fact that most Americans spend a good 90 percent of their lives indoors, it is readily apparent why so many people are concerned with indoor air quality. This is why so many are making sure that a home air purifier is a top priority for their household.

But it can be confusing, time consuming and frustrating to shop for the right home air purifier. There are many choices in air purifiers on the market. There is also much conflicting information about what is the best way to clean and purify the air in your home. Some of the considerations to have in mind while shopping for clean air purifiers are as follows:

Different home air cleaners target different types of air pollutants, so before beginning it is important to know what pollutants are common in your home so that you know what system will be the most effective for you. Some of the airborne particulates you may find in your home are: pet allergens and dander, dust mite allergens, plant and mold spores, pollen, fungi and tobacco smoke. These are the most common culprits that trigger indoor allergic reactions and asthma attacks. A HEPA air purifier is best suited for eliminating such airborne allergens.

If you are primarily dealing with household odors and gases such as cooking odors, kitty litter or other animal related odors, tobacco smoke, various chemicals and toxins, or gaseous pollutants such as aerosols and inside pesticides, then air purifiers with activated carbon filters will be best for your situation.

Since the different home air purifier technologies inherently have different weak areas and strong points, many of the current air purifiers combine these two main filtering methods into one unit. This is beneficial since most home environments are dealing with the need to reduce allergens and toxic particulates, but also have odors and gases that need to be controlled.

While HEPA air cleaners and activated charcoal, or a combination of the two, are the most common home air purifier you will find, there are other technologies for air purification you will see as well. These technologies include: ion generators and ozone generators, electrostatic precipitators, charged media filters, and antibacterial and germicidal filters.

A home air purifier can bring a great sense of relief in knowing that the air in your house is being routinely cleansed of the nasty indoor pollutants that can gather and cause health problems for your loved ones. When choosing the right air purifier for your home, compare purchasing costs, operating costs and filter replacement costs before making your final choice.
