Systems and methods for increasing removal efficiency of at least one filter medium. In some embodiments, at least one oxidizing agent is introduced into the flue gas stream, so as to react SO2 with the at least one oxidizing agent to form sulfur trioxide (SO3), sulfuric acid (H2SO4), or any combination thereof. Some of the embodiments further include introducing ammonia (NH3) and or dry sorbent into the flue gas stream, so as to react at least some of the sulfur trioxide (SO3), at least some of the sulfuric acid (H2SO4), or any combination thereof, with the ammonia (NH3) and form at least one salt.

Disclosed is a skin care device using plasma. The skin care device may include a first plasma generating device; and a main body configured to supply power to the first plasma generating device and to control the first plasma generating device based on an input from a user.

Disclosed is a plasma generator. The plasma generator may include a gripping portion including at least one interface unit configured to receive an input from a user; a head portion including a plasma generating portion configured to generate the plasma; a first cartridge configured to detachably couple at a first end of the head portion and generate the plasma over a predetermined region; and a light irradiation portion provided at a second end of the head portion.

An ionization device may be configured to be portable, and to rest on a surface such as a floor or desk top. The ionization device includes an air-intake port, an ion generator, an ozone catalyst for removing at least some ozone from air, and an air discharge. Air enters the device through the air-intake port, and at least some of the air is ionized to remove particulates. The air is then moved past or through the ozone catalyst to remove at least some of the ozone from the air. A controller may be used to monitor particulates, temperature, humidity, and/or other relevant factors and/or to adjust the ionization level.

A core to receive an air flow having foreign object debris (FOD) has an inlet plane at which the air flow can enter the core, a fin element having a fin configuration, and a first protective component. The first protective component is constructed of a material and has a first protective configuration sufficient to repel FOD.

The present invention relates to an apparatus for manufacturing oxygen water or hydrogen water. The apparatus for manufacturing oxygen water or hydrogen water is configured such that oxygen or hydrogen generated from a device for generating oxygen and hydrogen by electrolyzing water is supplied to water using a fluid pump for manufacture of oxygen water or hydrogen water. The apparatus is configured to easily, quickly, and effectively manufacture oxygen water or hydrogen water in a plastic water bottle by dissolving high purity oxygen or hydrogen in source water in the bottle directly. Accordingly, by drinking oxygen water or hydrogen water manufactured thereby, fresh oxygen is supplied to the body, and hydrogen is also supplied to the body and removes harmful reactive oxygen species or reactive carbon species, thereby enabling a healthy life.

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.

An air treatment system (1) arranged for treating polluted air (A.sub.pol) at least by means of an air particle filter, and wherein said air treatment system comprises an air treatment unit placed upstream of the air particle filter and being arranged for directing a sub-flow (A.sub.sub) of the polluted air (A.sub.pol) through said air treatment unit (2) and for subjecting the sub-flow (A.sub.sub) to a photooxidation process. The photooxidation process in the air treatment unit (2) is so efficient that the overall concentration of gas-pollution of the combined air flow A.sub.corn is significantly reduced whereby large volumes of polluted air can be treated in a fast, inexpensive and effective manner.
