carbon filter |

Pluses: Low filter
replacement cost. Good ratings by leading consumer magazine. An above
average purifier. This unit tested well in our independent testing
however, due to the ozone smell and higher than average product returns,
we've rated it only 3 stars.

per month. Some levels of ozone are produced as a by-product and the smell
may be annoying to most people.
The carbon filters are not effective for smoke and odor removal.
