The same revolutionary technology professionals use to eliminate odor in the most challenging environments is now available for the home.
No Odors
Our HEPA filter traps the odor as it passes through and then ODOGard® bonds to the odor, removing the smell for good.
No Ozone
Active HEPA+ uses a combination of technologies that eliminate odors and more without the need for ozone.
No Worries
We’re so confident in Active HEPA+ that we’ve given it an industry best 10-Year Warranty, so you can rest easy.
Not all testing is the same.
That’s why at Greentech, we have invested heavily in testing our new Active HEPA+ to make sure we’ve got it right. We test in EPA certified testing chambers as well as in many tough “real world” environments.
