Save Money Shopping Online, and Don’t Get Ripped Off 

There are not many official online retailers of AllerAir air quality products and unfortunately the internet is full of scams. As a general rule of thumb, if the deal seems too good to be true, it probably is. Cheap cut rate online deals often end up being a used or refurbished unit, which do not come with AllerAir's top rated 10 year warranties. Or even worse, you may end up buying a cheap discount air cleaner that doesn’t have the energy efficiency, features or real air cleaning power provided by top-rated AllerAir air filtration systems.

And buying from us is definitely better than direct.  If you buy direct, you'll have to pay shipping.
