Included herein are filtration systems that can proactively pulse clean filter elements in response to anticipated changes, such as anticipated changes in filtration performance or anticipated changes in filtration system demand. In an embodiment, a filtration system is included having a filter element mount for a filter element, a compressed gas supply, and a valve, wherein opening the valve results in a pulse of gas directed at the filter element. A control circuit can control the valve. A communications circuit can receive data related to an anticipated change, such as data regarding an anticipated change in filtration performance and/or data regarding an anticipated change in filtration system demand. The control circuit can execute operations based on the anticipated change data such as adjusting a pressure drop threshold and initiating proactively opening the valve in the absence of a pressure drop threshold being crossed. Other embodiments are also included herein.

A vehicle system includes: a heating, ventilation, and air conditioning (HVAC) system including: a passenger cabin air filter; and a blower configured to draw air through the passenger cabin air filter and blow air into a passenger cabin of a vehicle; an olfaction sensor configured to measure an amount of a chemical in air in a duct of the HVAC system downstream of the passenger cabin air filter; and a filter module configured to determine and indicate whether to replace the passenger cabin air filter based on the amount of the chemical in the air measured by the olfaction sensor.

A multimodal airborne pathogen control apparatus and system configured to direct and decontaminate a volume of indoor air of occupied spaces and reduce the risk of spreading airborne contagions. Certain aspects of the multimodal airborne pathogen control apparatus and system may include one or more infection control modalities including, but not limited to, dielectric Cold Plasma generation, non-ozone producing UV-C light, True HEPA filtration comprising a monoterpene phenol-impregnated filter material, and configurable intake/output ducting to direct airflow to/from a desired area and regulate interior atmospheric pressure.

A filtration system for use in connection with a central vacuum system in a hospital or other medical facility. In certain aspects, the filtration system comprises a removable filter for removing contaminants; a fitting adapted for connection to a central vacuum source/system which provides constant suction, which fitting is positioned between the filter and the central vacuum source; a flow control valve positioned between the filter and the fitting; wherein the relative positions of the fitting, flow valve and filter prevent contaminants from being discharged into the central vacuum system. In other aspects, the system provides variable filter life based upon variable flow.

Implementations described and claimed herein provide air filtration monitoring. In one implementation, air filtration data is received from one or more air filtration systems over a network. Each of the one or more air filtration systems is configured to provide purified air into an enclosed space by removing ultra-fine particles from air using at least one primary filter. The air filtration data is captured by one or more sensors. The air filtration data is correlated based on at least one monitoring parameter, and air filtration analytics are generated from the correlated data. In another implementation, health data is received from a controller in an air filtration system. The health data is captured using one or more sensors. Health monitoring analytics are generated from the health data, and feedback is generated from the health monitoring analytics.

A general ventilation and air filtration system includes an air filtration control unit that monitors and controls an air flow through an air filter and maintains the air flow at a target velocity set point. The target velocity set point is maintained by monitoring and regulating the power of a motor powering a blower that generates an air flow through the air filtration system and through the air filter. By regulating the air flow and maintaining it in the target set point, power consumption and air filter life are significantly improved.

An integrated autonomous air purification device for taking in polluted air, carrying it through the inside of the purification device where it passes through a set of filtering elements (1) that trap the dust particles contained in the air; ultraviolet-light lamps (2) that transform NO.sub.X and CO gases in the air into harmless compounds; an activated carbon filter (4) that traps and eliminates the volatile organic compounds and inorganic acidic gases; second filtering elements (5) that carry out a second filtering; and an extraction hood (6) configured to direct the air coming out of the second filtering elements (5) to at least one nozzle (7) that expels the air to the outside of the purification device.

Aspects herein include filtration systems with multitiered data exchange capabilities. In an embodiment, a filtration system with multitiered data exchange capabilities is included. The system can include a first data communication tier including a filter element, the filter element storing data, and a first sensor. The system can include a second data communication tier including a reader device in communication with the first sensor. The system can include a third data communication tier including an engine control unit (ECU) in communication with the reader device, wherein the ECU stores data. The second data communication tier receives data from the first data communication tier and the third data communication tier. The second data communication tier executes operations on the received data to create a processed data set. Further, the second data communication tier sends the processed data set to the third data communication tier. Other embodiments are also included herein.

Methods for controlling air filtration in an enclosure include measuring contaminants in an internal and an external environment using respective internal and external contaminant sensors. An increase in a corrosion rate is determined for objects in the enclosure if unfiltered external air intake is increased for cooling based on the measured contaminants in the internal and external environments. An air pressure needed to filter external air using a filter in the filtered air intake is determined. An intake of unfiltered external air is controlled by bypassing the filter in the filtered air intake, based on the corrosion rate increase and the determined air pressure. A predicted filter lifetime is updated based on the intake of unfiltered external air. A warning is provided if the contaminant sensor information associated with the filter exceeds an instantaneous failure threshold or if the determined remaining filter lifetime falls below a filter lifetime threshold.

A fume extraction apparatus (1) which comprises an identifier module (20a; 20b) capable of communicating a credential signal over an air interface, a receiver (31) for receiving the credential signal and validating the same, the identifier module attached to a removable filter unit (5; 6); and the receiver is secured to a body of the apparatus, which body removably receives the filter unit.
