If you think the world of home air purifiers is already confusing, get ready for the next generation of super high-tech hybrids that promise to dramatically improve indoor air quality.
These incredible units are known as smoke-eaters, but they are really just hybrid purifiers that combine existing methods with ultra-secret new technologies. What they don't have is filters!
Smoke-eaters typically utilize both ultraviolet and electronic purification methods. First, air is exposed to UV lamps that break down bacteria, smoke and other contaminants. Then, some form of generator creates an electrostatic charge that produces negative ions that attach themselves to the remaining particles. Most smoke eaters also use some type of ozone generator for the same purpose.
The drawback to these gizmos is the cost - all that proprietary technology can push the price tag up to $500-$800 for a portable home purifier. The advantages, though, include the absence of paper filters that need replacing, and the extraordinary efficiency of many models. Some manufacturers claim their units are significantly more effective than industry-leader HEPA filters.
Another concern about smoke-eaters is that they produce ozone, which can be a health hazard at certain levels of concentration. If you're worried about ozone in the air, best avoid these technologies.
Nevertheless, smoke-eaters are a great example of the kind of innovation that is driving the air purifier market. Don't be surprised if these high-end products become common features of homes everywhere in the next few years!
