Our award-winning Infinity air purifier doesn’t just filter air: Its Captures and Kills™ technology is unforgiving when it comes to airborne pathogens such as bacteria, viruses and mold. Grizzly? Yes—if you’re a mold spore. This whole-house air cleaner also re-purifies circulated indoor air as many as 8 times an hour. Those poor pathogens don’t stand a chance.
