An air treatment device includes: a casing having an inlet through which air is drawn, and an outlet out of which the air drawn through the inlet is blown; a blade configured to adjust a direction of the air blown out of the outlet; and a generator configured to generate an antimicrobial element that sanitizes the blade. The blade has a first surface, and a second surface opposite to the first surface. The blade is shiftable between a first position in which the antimicrobial element is provided to the first surface and a second position in which the antimicrobial element is provided to the second surface.

An air circulation and/or purification device for recirculating air and/or removing contaminants from the air which includes a housing having a top with an opening for air intake and a bottom, a fan contained within the housing, and a plurality of air output vents contained within multiple sides of the housing near the bottom of the housing. The bottom of the housing may include a conical shaped portion extending inward from the bottom of the housing or other structures to assist in expelling air from the housing in at least two different directions. The device may also include one or more filters designed to capture and filter out different types of contaminants.

An air purifier comprising at least one removable particulate filter, a fan or impeller and a motor for driving said fan or impeller, a top and, opposite thereto, a base and means for elevating said base from the ground, at least one side surface connecting said top and base, a base air intake disposed on said base and facing the ground in a working configuration a top air intake on said top and facing away from the ground in a working configuration and an air outlet located on said side surface.

The window air conditioning and heating unit controls the environmental conditions within a room of a building. The window air conditioning and heating unit mounts in a window of the room. The window air conditioning and heating unit measures and monitors the temperature of and the humidity in the air in the room. The window air conditioning and heating unit comprises an environmental control structure, a control circuit, and a housing. The environmental control structure provides the heat and mass transfer capabilities required to control the temperature and humidity within the room. The control circuit controls and powers the operation of the environmental control structure. The environmental control structure and the control circuit are contained in the housing.

The invention relates to an air purification device comprising a casing (1) that houses a fan (2) and a filter (3) placed in front of said fan (2), such that air passes through said filter (3) and exits the casing (1) by means of said fan (2), and is characterised in that said filter (3) is placed in a replaceable part (4) mounted in a detachable way in said casing (1), said replaceable part (4) comprising material with volatile substances (5). It allows an air purification device to be provided which allows for the purification of air and the diffusion of volatile substances at the same time.

A cover assembly is configured for disinfecting an air conditioning unit. The assembly includes a cover made of a pliable material that is shaped to be installed on the inside portion of an air conditioning unit. The assembly also includes an ozone generator configured to direct ozone into the air conditioning unit. When assembled on the air conditioning unit, such as a window AC unit or an evaporator of a mini-split system, the cover assembly can be operated to disinfect the air conditioner.
