Important: Only Purchase an Air Purifier After Researching the Facts



Choosing the right air purifier is an important long-term decision. There are literally dozens of brands and hundreds of different purifiers to choose from.

  • Which technology should you use?
  • What air space do you want cleaned?
  • Which type of purifier will work best for your situation?
  • How do you choose?
You don't need to become an expert, but spending a little time researching now will pay big dividends in the long run.

I would recommend two ways to use this website:

  • GOOD - Use the Index to browse the areas important to you.
  • BETTER - Start at the beginning and go through the 5-Step Guide.
If you choose to browse the Index, realize that a working knowledge of the technologies and types of purifiers will help you review and choose the best purifier for your needs. After browsing, if you find that you cannot make up your mind, start over at the beginning and work through the 5-Step Guide in order. It will help you make a better choice.
