First, this comparison from a user: "Now let me drop a note to how much we love our [XJ-3000] air cleaner! It is more effective than Sharper Image's Quadra. I am more than satisfied. I am delighted beyond belief as to how well this product works. I have had the most expensive hepa filters and none compare to your product. I am so lucky to have found you."
The air-cleaning benefits of negative ions are well understood and established in the scientific community. The XJ-3000C contains two high-density negative ion generators.
Air Filters versus Metal Collector Plates
Since the XJ-3000C draws air in with a fan, it collects far more pollutants. Further, the HEPA and activated carbon room air filters are far more absorbent than metal collection plates, and that prevents particles from becoming recirculated into the air.
Fan versus No Fan
Importantly, the fan also circulates the negative ions much more thoroughly throughout a room or area compared to a fan-less ionic air purifier. These ions cause particles to clump together, becoming too heavy to float in the air.
Germicidal UV Light Purification
The Ionic Breeze GP is priced at $499.
The UV lamps in each unit will need to be changed every year or so.
Both the XJ-3000C ionic air filter and the Ionic Breeze produce ozone. Ozone has air cleaning ability, but it can also cause an odor that is not always desirable.
The ozone output of the XJ-3000C can also be set to a significantly higher level than what the Ionic Breeze can create, making it more effective at removing odors when needed.
The XJ-3000C does have the HEPA/activated carbon air filter combination cartridge that needs to be replaced every one to two years, but it costs under $35 per replacement.
