Filter retainer mechanism for a portable air treatment system

Abstract

Provided is portable air treatment device and a system including a filter retaining mechanism for selectively retaining a replaceable filter assembly. The filter retaining mechanism includes a rigid, non-moveable body that reduces a size of an access opening to a filter chamber otherwise formed by the air treatment device housing, along with a bearing surface. The rigid body serves as a catch or latch, preventing unexpected dislodgement of a filter assembly from the chamber. The bearing surface is also rigid and non-moveable, and provides a means for easily inserting and removing a primarily non-permanently deflectable filter assembly about the rigid body.

Description

Background technique [0001] The present invention generally relates to air treatment systems, such as room air cleaners. More specifically, it relates to mechanisms for retaining removable filters within portable air treatment unit housings, and methods of inserting and removing filters from portable air handling unit housings. [0002] There are a variety of portable air treatment systems that can be used to filter or otherwise treat air in a closed environment. These air handling systems can take many forms and generally consist of a housing holding a blower or fan and a filter. The blower directs the room air to the filter to remove a variety of pollutants such as particles, dust, pollen, odors, and more. The treated air is then directed back into the environment where the system is located. The system can be designed to perform other functions (such as a dryer), but is generally designed to assist the user in removing and replacing filters. Then through this method, re...
