Biotech EdenPURE Area Air Purifier

February 2009. On its website, Biotech claims the EdenPURE Area Air Purifier uses four separate electronic mechanisms to remove pollutants. However, the EdenPURE scores dead last in Air-Purifiers-America.com's test of air cleaners (though, to be fair, the site does say this machine is quiet and well designed). Air-Purifiers-America.com doesn't recommend the EdenPURE for mold, and warns readers against using its ozone setting. The site has nothing to say about Biotech's claim that the EdenPURE can actually remove odors from walls and furniture -- as with other ionizing air cleaners, it's more likely that pollutants are settling on walls and furniture. The Honeywell Enviracaire 50250 (*est. $160) receives better reviews, especially from owners, and costs less.

We were only able to find a couple of reviews of the Biotech EdenPURE Area Air Purifier at the time of our last write-up, and unfortunately, neither of them are still available online. One was by Air-Purifiers-America.com -- which tested the EdenPURE's performance in a small room and compared it to other air cleaners. There was also a suspiciously positive "review" of the EdenPURE at CleanAirHouse.com, which we include to show how difficult it can be to find unbiased information about air purifiers. Consumer Reports doesn't include the EdenPURE in its most recent air purifier review, but their website does feature an article about ozone generators that mentions the EdenPURE. TheDailyGreen.com mentions the EdenPURE in a recent article about potentially dangerous air purifiers.
