After 30 years in the Air Cleaner Home Purifier industry I have watched people choose the wrong air purifier system hundreds of times. I'd like to help you avoid making that mistake. My suggestion, as the best way to begin, include these steps: STEP #1: Review the 10 types of purifier to determine which fits your needs (reviewed below)
STEP #2: Read the Comparison Chart below to choose several that match the type you need.
STEP #3: Watch any video reviews, spec sheets, particle tests and ratings from those models on this site to make your decision.
You'll discover a review on pretty much every brand name Air Cleaner Home Purifier on the market from the left menu. A complete list of air purifiers reviewed is available on the site can be found using the link below:
1 - Buying an air purifier that does not cover adequate square footage
2 - Discovering that the replacement filters are overpriced on the model purchased
3 - Choosing the wrong technology for the job (EX: buying an Oreck to get rid of dust when the Oreck does not include a HEPA filter, and hence is inadequate for dust)
4 - Failing to review the warranty terms
5 - Purchasing an overpriced infomercial model
#1 HEPA - For Particles including dust and pollen
