Air filtration and purification apparatus
First Claim
1. An apparatus for processing air comprising:
- a filter assembly having one or more filtering elements configured to receive ambient air from a chamber of a housing, the filter assembly including a receiving surface having an area;
an air flow guide located proximate an intake vent of the housing and having a first portion and a second portion, the first portion being configured to form a passage within the housing between the input vent and the second portion, and the second portion being configured to divert and accelerate air flow of the ambient air from the passage to the chamber such that a cross sectional area of the air flow in the chamber is substantially the same as the area of the receiving surface of the filter assembly; and
a fan configured to draw the ambient air from the chamber through the filter assembly and to generate processed air based on the ambient air.

Abstract
A method and apparatus for processing air is described herein. An example apparatus includes a housing, a high-velocity air flow guide, a filter assembly, and a fan. The high-velocity air flow guide includes a first portion and a second portion. The first portion is configured to form a passage within the housing, and the second portion is configured to divert and accelerate air flow of the ambient air from the passage to a chamber of the housing. The filter assembly includes one or more filtering elements configured to receive the ambient air from the chamber. The fan is configured to draw the ambient air from the chamber through the filter assembly and to generate processed air from the ambient air.

7. An apparatus for processing air comprising:
-
a housing having a chamber and an intake vent configured to receive ambient air;
a filter assembly having one or more filtering elements configured to receive the ambient air from the chamber, the one or more filtering elements being one of perpendicular or skewed relative to the intake vent;
a fan configured to draw the ambient air from the chamber through a receiving surface of the filter assembly and to generate processed air based on the ambient air; and
an air flow guide located proximate the intake vent and having a first portion and a second portion, the first portion being configured to define a passage between the second portion and the intake vent, and the second portion being configured to divert the ambient air from the passage to the chamber prior to the fan drawing the ambient air through the filter assembly so that a cross section associated with the air flow of the ambient air from the chamber is substantially distributed across a surface area associated with the receiving portion of the filter assembly. - View Dependent Claims (8, 9, 10)

11. An air filtration system comprising:
-
a housing having a bottom wall, and at least on side wall supporting a top wall to enclose an inner chamber;
an intake vent formed in the bottom wall and adapted to intake air from outside the housing;
an air flow guide adapted to divert ambient air from the intake vent into a first portion of the inner chamber, the air flow guide having a first portion and a second portion, the first portion adapted to form a passage between the intake vent and the second portion, and the second portion adapted to divert and accelerate the air from the passage to the inner chamber to form an air flow;
a filter assembly supported on the air flow guide;
a fan located within a second portion of the inner chamber opposite the first portion of the inner chamber and adapted to draw air from the first portion of the inner chamber through the filter assembly; and
an output vent formed in the top wall and adapted to discharge air outside the housing. - View Dependent Claims (12, 13, 14, 15, 16)

17. A method for processing air comprising:
-
receiving ambient air from an intake vent of a housing into a passage;
diverting the ambient air from the passage into a chamber of the housing via an air flow guide having a first portion and a second portion, the first portion and the intake vent being configured to form the passage;
accelerating air flow of the ambient air from a first air flow speed to a second air flow speed as the second portion diverts the ambient air into the chamber, the second air flow speed being greater than the first air flow velocity;
drawing the ambient air from the chamber into a filter assembly having one or more filtering elements configured to generate processed air; and
discharging the processed air through an output vent of the housing. - View Dependent Claims (18, 19)
