AIR PURIFIER FOR REMOVING PARTICLES OR CONTAMINANTS FROM AIR
An air purifier that removes particles or contaminants from air includes a base having an air inlet, an air outlet and an air flow path therethrough. An impeller urges air into the air inlet, through the air flow path and out of the air outlet and a motor drives the impeller. The motor and impeller are supported within the base. A foldable air filter is in fluid communication with the air outlet and is removably mountable to an exterior surface of the base proximate the air outlet.
1 . An air purifier for removing particles or contaminants from air, said air purifier comprising:
a base having an air inlet, an air outlet and an air flow path therethrough;
an impeller for urging air into said air inlet, through said air flow path and out of said air outlet;
a motor for driving said impeller, said motor and impeller supported within said base; and
a foldable air filter in fluid communication with said air outlet and removably mountable to an exterior surface of said base proximate said air outlet.
2 . The air purifier of claim 1 , wherein said air filter is foldable into a compact configuration for ease of storage and shipment.
3 . The air purifier of claim 2 , wherein said air filter has a minimum efficiency of at least 80% for particles sized in the range of 0.3 to 1.0 microns.
4 . The air purifier of claim 1 , wherein said air filter is inflatable to an upright and unfolded position when said motor is activated.
5 . The air purifier of claim 4 , wherein a grasping mechanism extends from a top surface of said air filter.
6 . The air purifier of claim 1 , wherein at least one light emitting device is located on an exterior surface of said base.
7 . The air purifier of claim 5 , wherein said air filter encloses said at least one light emitting device when said air filter is mounted to said base, said at least one light emitting device illuminating at least a portion of said air filter when said air filter is mounted to said base and providing a visual indication when the air filter is becoming clogged.
8 . The air purifier of claim 1 , further comprising:
a frame removably mountable to said base, wherein the frame surrounds said air filter when said air filter is mounted to said base.
9 . The air purifier of claim 8 , wherein said frame is comprised of at least two interconnecting segments that generally form a rectangular shape when assembled.
10 . The air purifier of claim 8 , further comprising:
a cover removably mountable over or around said frame, wherein said cover is air permeable.
11 . The air purifier of claim 10 , further comprising:
an elongated rod removably located within a portion of said frame to assist a user in unfolding said air filter.
12 . An air purifier for removing particles or contaminants from air, comprising:
a base having an air inlet, an air outlet and an air flow path therethrough, said base enclosing a motor for driving an impeller, said base including at least one light emitting device on an exterior surface thereof, and
an air filter removably mountable to an exterior surface of said base,
wherein said air filter encloses said at least one light emitting device when said air filter is mounted to said base, said at least one light emitting device illuminating at least a portion of said air filter when said air filter is mounted to said base and providing a visual indication when the air filter is becoming clogged.
13 . The air purifier of claim 12 , wherein said air filter is inflatable to an upright and unfolded position when said motor is activated.
14 . The air purifier of claim 12 , wherein said filter is foldable into a compact configuration for ease of storage and shipment.
15 . The air purifier of claim 14 , wherein said air filter has a minimum efficiency of at least 80% for particles sized in the range of 0.3 to 1.0 microns.
16 . The air purifier of claim 12 , wherein said air inlet and air outlet include louvered vents.
