The Air Bear® Supreme and the HE Plus 2000 are two whole-house air cleaners. The Air Bear Supreme is a media air cleaner with a filter rated at MERV 8. The filter has an initial pressure drop of 0.22 water column at 2,000 cfm. The HE Plus 2000 is an electronic air cleaner. The electronic air cleaner comes standard with an innovative airflow sensor and line cord that makes installation easy, the company says. The unit only activates when air moves through the ductwork, states the manufacturer. A charcoal after-filter is an optional accessory for both the media air cleaner and the electronic air cleaner.
