Odour Reduction Apparatus
First Claim
1. An air filter comprising an air inlet to allow air containing particles to enter the air filter;
- an air outlet to allow the air from which at least some particles have been removed to exit the air filter;
one or more baffles disposed between the air inlet and the air outlet to allow the air containing particles to contact at least a portion of the one or more baffles; and
one or more fluid releasing means for releasing fluid over the at least a portion of the one or more baffles, thereby in use inducing a charge on the surface of the baffles to which the particles are attracted, thereby reducing the amount of particles in the air which entered the air inlet.

Abstract
The invention is an air filter for reducing the amount of particles in air. In the preferred form, the particles are odour particles. The air filter comprises two spaces disposed between an air inlet and an air outlet. Odorous air is drawn into the air filter and pre-treated in a first space, having air flow baffles and jets which both agitate and charge the air by a process of triboelectrification. In the second space the airstream impinges upon a number of spaced-apart baffles or structured layers. The odour particles in the air are attracted to the surfaces of the baffles and are removed by the action of the water flow. The air filter of the present invention can treat air from installations such as agricultural operations, air from apartment buildings, air from restaurants, factories and other industrial facilities, vehicle exhaust system and effluent ponds and is also applicable to removing other particles types such as pollen.

1. An air filter comprising
an air inlet to allow air containing particles to enter the air filter; -
an air outlet to allow the air from which at least some particles have been removed to exit the air filter;
one or more baffles disposed between the air inlet and the air outlet to allow the air containing particles to contact at least a portion of the one or more baffles; and

15. An air filter comprising:
-
a first space and a second space, disposed in air flow communication between an air inlet for receiving air containing particles and an air outlet for exhausting air from which at least some of the particles have been removed;
the first space including one or more first space fluid releasing means disposed to release first space fluid into the air containing particles flowing through the first space;
the second space including one or more second space baffles disposed to allow the air containing particles flowing through the second space from the first space to contact at least a portion of the one or more second space baffles, and further including one or more second space fluid releasing means for releasing second space fluid over the at least a portion of the one or more second space baffles thereby in use inducing a charge on the surface of the baffles to which the particles are attracted. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)

35. A method of filtering air, the method comprising:
-
in a first space, mixing air containing particles with a first space fluid to produce mixed air;
causing the mixed air to flow into a second space, the second space having one or more second space baffles;
causing the air containing particles to contact at least a portion of the one or more second space baffles, causing second space fluid to be released the one or more second space baffles thereby inducing a charge on the surface of the baffles;
in the second space, removing the particles from the mixed air by causing the air to be attracted to the charge induced on the surface of the baffles to produce air with a reduced amount of particles; and
expelling the air with the reduced amount of particles from the second space. - View Dependent Claims (36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53)

54. A method of filtering air, the method comprising:
-
causing air containing particles to flow into a space via an air inlet;
causing the air containing particles to contact at least a portion of one of more baffles disposed within the space;
releasing fluid over at least a portion of the one or more baffles thereby inducing a charge on the surface of the baffles; and
expelling air with a reduced amount of particles from the space. - View Dependent Claims (55, 56, 57, 58, 59, 60, 61, 62)
