With the rise in allergy sufferers, it is no wonder that air purifiers are growing in popularity. However, there are so many models available. How do you make sure that you are buying the right air purifier for your home? These air purifier buying tips should help you successfully choose the right model for you.

One of the most important things you should do when you are buying an air purifier is to figure out the square footage of the room or rooms where you will be using it. Don’t take a wild guess. This is really an important measurement. A purifier that is designed for a smaller room won’t adequately clean a room that is too big for it. To figure out the square footage of a room, measure the length of one side of the room and the width of another side. Multiply the two numbers together. This is the square footage. Once you know this number, you can look at the purifier’s information to be sure it is supposed to clean a room that is at least as big as your room, if not larger.

Next, check to see whether the air purifier you are considering is designed to clean the pollutants that are in your home. Not all purifiers clean tobacco, pollen, dust, or pet dander. If your home has all of these pollutants, you will need to look for an air ionizer or a combination HEPA filter/air ionizer in your purifier.

Another important consideration for most people shopping for an air purifier is the loudness of different models. Usually, ionizer models are much quieter than HEPA filter models.
 
However, ionizers must be used in conjunction with a vacuum cleaner to be effective, since they do not actually remove dust and other pollutants from the room. Ionizers simply make all of the pollutants so heavy that they fall from the air and drop to the ground. 

Before you make a final decision, you should also consider the life of the filter in the air purifier. Replacement filters can be quite expensive. Ionizers do not need any filters, but they do need to be cleaned quite often.

Finally, you should take a look at how often air is circulated through the air purifier and back into the room. The best purifiers circulate the room’s air at least 5 times an hour. To find out how many times the model you are considering circulates air, look for the ACH rating, which stands for air changes per hour.
