A multiuse home station includes an autonomous surface cleaning apparatus docking station, an autonomous surface cleaning apparatus charging station, and a room air cleaner unit, wherein the room air unit uses a portion of the autonomous surface cleaning apparatus docking station.

Filter systems and methods described herein include one or more spacer elements positioned in the dirty air chamber along with the filter elements attached to the spacer elements. The dirty air inlet delivers a dirty air stream into the dirty air chamber along a dirty air flow axis.

A vacuum cleaner including a main body and a filter assembly. The main body includes a vacuum motor for drawing a flow of air through the vacuum cleaner. The filter assembly includes a first filter, and a filter housing configured to form part of an outer surface of the vacuum cleaner. The filter assembly defines a longitudinal axis, and a through-hole which runs along the longitudinal axis through the filter assembly. Also disclosed herein is a filter assembly for said vacuum cleaner.

A method and a system for rapidly predicting the frying and bubbling tendency of edible oil, the method comprising: heating the edible oil, and immersing a polar component content detection probe into the oil to measure the initial polar component content of the edible oil; a frying state: removing the detection probe, placing frying food into the edible oil and frying same, extracting the frying food after frying, and observing the highest value of the frying oil bubble height and recording same as an initial bubble height; an air introduction state: immersing the detection probe into the edible oil and introducing air into the edible oil, and continuing to introduce air and heat until detecting that the polar component content of the oil has reached 10%; repeating the frying state; and formula fitting. The present method does not require actual frying, as the frying and bubbling tendency of the oil can be predicted with a 60 g sample, saving raw materials and implementing a comprehensive evaluation of the bubbling properties; the system equipment is simple, and is suitable for industrial practical operations.

An air purification unit and/or system for an environment with multiple seated individuals, including an air collector and air purification chamber, to be used independently from or in conjunction with the environment's air handling system.

An air purifier including a fan having a plurality of fan speeds; a filter, wherein the fan draws air through the filter; a user interface in communication with a control system; wherein upon activation of the control system, the control system identifies an initial air quality index (AQI) based upon a geographic location of the air purifier, a room size based upon the type of room in which the air purifier is placed, and identifies a fan speed set by a user through the user interface, and determines a target air quality index achievable in thirty minutes of fan operation is provided. Further provided is an air purifier capable of predicting and updating time to achieve a target air quality and a target air quality based on a number of environmental factors.

This invention is a smart face mask for air filtration with a transparent mouth-covering portion, an active air filtration system which filters both air inflow and air outflow, an environmental or biometric sensor, and a smart control mechanism wherein the operation of the active air filtration system is automatically adjusted based on analysis of data from the sensor.

The invention is a table top filtration device designed to filter noxious fumes on or near the table. In one embodiment, the tables are manicure and pedicure tables.

An apparatus configured to purify air and sanitizing including a main base including one or more buttons configured to operate the apparatus, a lid attachable to the main base and that includes one or more ventilation perforations to intake air and an orifice to output purified air, a filter adjacent to the one or more ventilation perforations and enclosed in the lid, wherein the filter is configured to remove at least bacteria from atmospheric air and extract purified air, a fan configured to intake atmospheric air into the filter and blow purified air extracted from the filter outside of an orifice of the lid, a tank configured to store liquid, wherein the liquid includes at least liquid sanitizer, a pump configured to output liquid stored in a tank, and a cavity section that includes an outlet configured to output the liquid sanitizer in response to actuation of the pump.

An alternative device to a mask that blocks a patient's aerosol and avoids contamination of the patient's surrounding environment is described. The device has a flexible arm that holds an aerosol disposal pipe with one side connected to a wall, a bed, or pole attached to a floor. The second side of the flexible arm is attached to a circular or elliptical pipe that covers the face of the patient. The elliptical or circular pipe comprises of two independent moving and rotating halves to create two aerosol sucking planes. The sucking function is provided by sucking fans attached to the two halves of the circular or elliptical pipes or by a remote pump. The sucked aerosol may be filtered and released to the environment or guided to a sink P-Trap or an inlet of sewer.
