I'll start by saying that the " Best Air Purifiers " (according to any online reviews) have only a 99% chance of being the wrong air purifier for you.
1 - There are 10 technologies. Do you know them? Do you know which ones fit your needs?
2 - Most air purifiers only use 2-3 technologies and choose incorrectly.
3 - Most manufacturers overcharge for replacement filters so consumers end up spending too much.
4 - The size of the room (square footage) will determine which air purifier is best and since all air purifiers are different - most people choose one that is too big or small.
1 - Watch Part 1 of the Video below: 10 Technologies Explained
2 - Then watch Part 2: How to Determine Square Footage
3 - Review the Comparison Chart (via the left menu) to match several models against your chosen technologies and square footage
4 - Watch the Video Reviews on the site of each chosen model,read the specification sheets, and pro's and con's of each model
5 - Make an informed decision
I've included replacement filter costs and warranty information which can be important in terms of operating costs and long term reliability. Filters should not cost over $80 (no matter how big) and Warranties should be a minimum of 3-4 years, ideally five.
Once you have several potential matches then the video reviews should help you determine the best for your needs. Call me if you need any advice at 1-800-215-1689. Good Luck!
