My neighbor has come over and mentioned the benefits of clean air purifiers in my house. Before, he would cough and sneeze constantly because of the smoke and my cats. Now he comes over and we enjoy a giant cup of tea together and talk for a while, all without him getting irritated once.

If there are smokers in your house or family, you should think about getting an air purifier. Even if you do not smoke or have pets, you can still reap the benefits. Have you ever walked into someone's house and a wall of cooking smells smacks you in the face? It is even worse if the cook is not good at cooking, but an air purifier can help abolish these horrible occasions.

When the time comes to purchase air filters, look at how often it will regenerate the air in room. Most heavy-duty purifiers will clean the air every hour, while others will take drastically longer. If your purifier is simply providing you with much fresher air to breathe, perhaps the time it takes to clean the air isn't as large a consideration; however, if you are purchasing your purifier for an allergic child's room, the turnaround time is a much larger factor.
