In some embodiments, an indoor air cleaning apparatus and a method for removing at least a portion of at least one type of gas from an indoor airflow are disclosed. The apparatus may comprise a cabinet; at least one sorbent bank comprising at least one cartridge; a fan assembly comprising at least one housing including at least one housing inlet and at least one housing outlet, at least one motor and at least one impeller; and a heating element configured to operate in at least one of two modes: an active mode and an inactive mode; and a controller configured to operate in at least two modes: an adsorption mode and a regeneration mode.

A disinfectant misting system and assembly operably configured to selectively control emission of an atomized spray of disinfectant solution within an enclosed structure at desired times, in desired locations, and for a desired amount of flow through at least one electronic control unit in an effective and efficient manner, and comprising a liquid supply housing with a liquid disinfectant storage tank housing a disinfectant solution, a disinfectant supply pump, an electronically controlled room pressure regulation component, and an electronically controlled pump pressure regulation component fluidly couplable to a liquid conduit assembly operably configured to transport the disinfectant solution to at least one disinfectant emission housing operably configured to emit an atomized spray of the disinfectant solution into the enclosed room space.

A gas exchange device for filtering a gas is provided. The gas exchange device includes a gas-intake channel having a gas-intake-channel inlet and a gas-intake-channel outlet, a gas-exhaust channel disposed aside the gas-intake channel and including a gas-exhaust-channel inlet and a gas-exhaust-channel outlet, a purification unit disposed in the gas-intake channel for filtering the gas passing through the gas-intake channel, a gas-intake guider and a gas-exhaust guider for guiding the gas, a driving controller disposed in the gas-intake channel near the gas-intake guider for controlling enablement and disablement of the purification unit, the gas-intake guider and the gas-exhaust guider, and a gas detection main body for detecting the gas and generating detection data.

The present disclosure relates to an air purification filter including a substrate, and an enzyme and glycine supported on the substrate, wherein the enzyme includes at least one enzyme selected from the group consisting of β-1,3-glucanase, chitinase, lysozyme, protease, glycosidase, β-galactosidase, endo-β-N-acetylglucosaminidase and endolysine.

To provide a method for disinfecting air and/or surfaces which can be carried out truly continuously, in particular for essentially 24 hours a day, with people and/or animals present, the a method for disinfecting air and/or surfaces is proposed, wherein a disinfectant is dispersed continuously into a volume and/or area to be disinfected, wherein the disinfectant comprises electrolyzed and/or sterilized water containing hypochlorous acid, and wherein the disinfectant is dispersed at a dispersion rate between 0.5 ml/m.sup.3/h and 12 ml/m.sup.3/h.

In some embodiments, there is provided a scrubber system for cleaning return air in an HVAC unit, where the scrubber system attaches directly to an inlet of the return-air side of the HVAC unit, for example, by the mating of a flange on the system with a matching flange on the HVAC unit. The bolt-on scrubber system may comprise one or more sorbent materials, a fan for circulating return air through the sorbent, a damper-controlled inlet and a damper-controlled outlet to the attached return air side of the HVAC unit. Further, an additional air flow channel and a damper may be included in the system to control the flow of outside air into the HVAC unit. In some embodiments, the sorbents may be contained in removable inserts.

An air purification assembly including: a chamber including an air intake for the passage of polluted air, an air outlet for the passage of purified air and a base provided with a means for creating a circulation of forced air in the chamber, a plurality of detachable cartridges housed in the chamber, the cartridges being adapted to be simultaneously traversed by the polluted air circulating in the chamber in order to purify the air, each of the cartridges being provided, at its intake, with an opening and closing mechanism for respectively allowing air to circulate or for blocking the circulation of air through the associated cartridge, the opening and closing mechanisms being controlled by control means configured to open or close the cartridges separately or in combination so as to adapt the air flow as a function of predetermined parameters of the quality of the air to be purified.

In some embodiments, an indoor air cleaning apparatus and a method for removing at least a portion of at least one type of gas from an indoor airflow are disclosed. The apparatus may comprise a cabinet; at least one sorbent bank comprising at least one cartridge; a fan assembly comprising at least one housing including at least one housing inlet and at least one housing outlet, at least one motor and at least one impeller; and a heating element configured to operate in at least one of two modes: an active mode and an inactive mode; and a controller configured to operate in at least two modes: an adsorption mode and a regeneration mode.

There is disclosed a system and process for purifying air. The system includes a housing and a plurality of inner and outer chambers. A solution of water and a biological reagent is configured to flow around the inner and outer walls of the inner and outer chambers while air is passed adjacent to this fluid flow. This causes an interaction between the air and the fluid solution to cleanse the air. The air is then discharged from the chamber. There is also disclosed a container having a rolling base allowing the container to be more transportable.
