Air purifiers claim to pull out the dust and debris that is in the air. They claim to rid the home of bacteria that can make you ill as well. But, do they actually work? Are they worth the investment? And, how in the world should you choose the right one if they are worth the purchase? While there are many models out there and there are many benefits to using them, youll find that not all air purifiers are worth it. Those that are, though, can greatly improve the quality of air within your home.

FACT: The air within any home is much dirtier than the air outside. This is due in part to the ability of the environment to neutralize bad odors and actually clean the air naturally. But, inside the home, there is little to no ability for the air to rejuvenate mainly because there arent many plants within the home environment to help filter the air as they do in the environment. This is where the air purifier comes into play.

Allergens

One of the main reasons to use an air purifier is to get rid of allergens within the air. Allergens are particles that cause allergies. They can be pollen, dust, mold spores and even pet dander. Often caught in the carpets, upholstery and other areas of the home, allergens cause a great deal of discomfort to individuals suffering from allergies. For those individuals that do not have allergies, over exposure to allergens can cause allergies. For those that need relief, an air purifier can help.

Other conditions in which the air purifier can help with the air is for those that smoke. You have heard that second hand smoke is more deadly than that of smoking? This happens because of the particles and even the gases that are emitted from smoking enter the room and are breathed in by others.

How Air Purifiers Can Work

There are several methods that are used in air purifiers. While there are benefits to most of them, not all of them will be right for your specific needs.

Filter Systems: Filter systems pull air into the unit and then clean it by passing it through a filter. Some will need to be replaced frequently while others are just wiped clean.

Absorbents: There are also some products that are used in air purifiers to help soak up the bad stuff so to speak. An example here is the use of charcoal.

Ionizers: These are also known as electrostatic charges. These cause particles within the air to become charged and attach to themselves. This causes them to fall to the ground or to other surfaces for easy clean up. UV Lights: These are also methods for cleaning are through the use of ultra violet lights.

There are several other options out there, but it is important to really understand not only which air purifiers are out there but also which products are the best of them. One way to do this is to look at the CADR of the product. The Clean Air Delivery Rating is a rating that provides for how well the air purifier works as compared to other air purifiers. The higher it is the stronger the power of it to clean the air. They are rated by the Association Of Home Appliance Manufacturers.

When choosing an air purifier to put into your home, make sure that you look at several models and compare their ability to meet your needs. Some products are better for allergen removal while others work well for debris removal. Still, youll need to determine your needs for whole home air purifiers. Or if you would like to only purify one room, youll need to insure that the unit is large enough for the room placed in. Another benefit is to use consumer reviews provided on the web for additional help in choosing one product or the next.

Air purifiers can be beneficial and should be used as long as they are chosen carefully.
