true hepa filter, they are much better at taking odors and allergens out of the air than the ionic machines, they trap smaller particles than the ionocs.
I have a Lifewise air puifier (hepa) that I paid $99 for at Radio Shack, it works great, even removes popcorn smell in minutes. I tried the ionic machine first cause it was cheaper, but it didn't remove the smells of cooking very well.
Try a Lifewise hepa, you can always return it if it doesn't work for you.
Be sure to get a unit that is rated for your room size. The ratings will be on the box.
There are also units that have both technologies built in, so you could still use your ionicbreeze in addition to a hepa.
Here is a site that explains the differences:
Clearing the Air About Air Cleaners - Unlike Ionic Air Cleaners, Products With HEPA Filters Work and Are Safe
Business Wire Apr 11, 2005
The Holmes Group, a leader in the air cleaner category, wants to "clear the air" by educating consumers about the differences between ionic products, and products with HEPA-based filter technology. An article, "New Concerns About Ionizing Air Cleaners" in the May 2005 issue of Consumer Union's Consumer Reports raises serious doubts about the effectiveness and safety of ionic air cleaners such as Sharper Image's(R) Ionic Breeze Quadra. In sharp contrast to ionic air cleaners, HEPA-based products with fans work and they are safe.
"We welcome the findings from Consumer Reports as there are many misconceptions about the efficacy of ionic air cleaning products that have been marketed for years through infomercials and print advertising," said Paul J. Powers, Jr., senior vice president and general manager, Home Environment Division, The Holmes Group. "In addition to exposing the potential dangers posed by the high levels of ozone emitted from ionic air cleaners, the magazine affirmed what we have been saying for years - most high-priced ionic air cleaners are relatively ineffective. But, the public deserves to know the conclusions reached in the Consumer Reports story are not an indictment of the entire air cleaner category."
