A symmetric pair of mounting brackets for mounting one of a plurality of air filters to a mounting plate of an air conditioner unit are provided. The mounting brackets each define a plurality of mounting surfaces with equidistantly space mounting holes. The mounting surfaces are spaced apart from a plurality of retention surfaces, with the distance between each respective mounting surface and retention surface varying to accommodate a different filter size such that the air conditioner may operate using different filter sizes by simply changing the installation orientation of the mounting brackets.

An air conditioner unit may include a housing, an outdoor heat exchanger assembly, an indoor heat exchanger assembly, a compressor, and a sterilization light assembly. The housing may define an indoor portion and an outdoor portion. The housing may further define an exhaust outlet downstream from the indoor portion to exhaust air therefrom. The sterilization light assembly may be disposed within the housing to transmit an ultraviolet light emission thereto. The sterilization light assembly may include a support board, an ultraviolet C (UVC) light source, and a lens casing. The UVC light source may be mounted to the support board and configured to emit radiation between 200 to 280 nanometers. The lens casing may be disposed over the support board and seal the UVC light source to prevent moisture from contacting the UVC light source.

An air conditioner unit may include a housing, an outdoor heat exchanger assembly, an indoor heat exchanger assembly, a compressor, a bulkhead, and a sterilization light assembly. The housing may define an indoor portion and an outdoor portion. The housing may further define an exhaust outlet downstream from the indoor portion to exhaust air. The outdoor heat exchanger assembly may be disposed in the outdoor portion and include an outdoor heat exchanger. The indoor heat exchanger assembly may be disposed in the indoor portion and include an indoor heat exchanger and an indoor fan. The bulkhead may be disposed between the outdoor heat exchanger and the indoor heat exchanger along a transverse direction to define the indoor portion and the outdoor portion. The bulkhead may further define a vent aperture therethrough. The sterilization light assembly may be disposed within the indoor portion downstream from the vent aperture.

A smart artificial intelligence based mobile robot having an air purification, humidification, dehumidification, and ultraviolet cleaning-based system to remove pathogens is disclosed. The robot also acts as an emergency alert system for break-ins and human fall detection using AI algorithm. The mobile robot operates and navigates intelligently using real time data collected from the environment through various sensors and input devices. An object detection module may use inputs from the camera to recognize people, pets, and others by pre-trained machine learning data set. The mobile purification, humidity management and sanitizing robot includes a ball bearing for balance and a motor controller, which drives two motors and wheels. The central controller of the smart mobile robot system has memory and processor to handle navigation, communication, notifications, and air handling system through real time data collection.
