Finding the right air purifier can become a daunting task. For over 30 years, I've been involved with air purifiers and have helped make recommendations for thousands of people like you. The following information is designed to shorten your learning curve to help you find the right air purifier for you.
1) Which of the 10 Air Purifier Technologies match my needs? (If you don't know what the 10 technologies are watch the video near the bottom of the page)
2) What is the square footage for my room? This is determined by multiplying the width by the length. (You can approximate this, but be sure to factor in high ceilings.)
Once you have these two questions answered view the air purifier comparison chart on our top 10 models to see ratings, square footage, filters included,warranty info, and prices. The video further down the page will walk you through the technologies and what to look for. Because each technology has different strengths and weaknesses (EX: HEPA is good for allergies but not odor) it's likely you'll be looking for a multi-technology air purifier. The chart below can be more easily viewed on smaller screens via the link to the right.
Mistake #1: You don't know the 10 technologies and end up missing the technology that solves your problem.
REASON 2: You don't understand some of the questionable practices of air purifier manufacturers (EX: you end up buying an air purifier with a limited warranty, or overpriced replacement filters).
REASON 3: You pay too much for an air purifier because the infomercial or marketing convince you it will solve your problem.
To compare air purifiers properly you'll want to use this information to choose the best one for you.
I hope this helps you as much as it has helped others...
