A method for treating a fluid is provided. Particles are coated with quaternary ammonium or phosphonium compounds (“quats”). Fluid is passed over the particles. The biocidal properties of the quats treats the fluid.

An essential oil reflux-type atomizer comprising the following structures: chassis (10), housing (30), atomization chamber (310), gas pump (21), gas tube (22), gas nozzle (23), oil nozzle (24), filter atomization mechanism (40). The filter atomization mechanism (40) is installed in the housing (30) and has a plurality of filter housings (41). A lower end of each of the filter housings (40) has one or more through holes (411). When the gas nozzle (23) ejects an airflow, the airflow draws out the essential oil through the oil nozzle (24) to form a mixed airflow which passes through each of the filter housings (41) successively. Larger essential oil droplets in the airflow are filtered by each of the filter housings (41) to be recycled, while the atomized essential oil gas will pass through the through holes (411) of each of the filter housings to be dispensed. At the same time, the essential oil droplets in the through holes (411) are re-atomized by the airflow to improve the atomization performance. The atomization chamber (310) comprises a guide board guiding the airflow from the gas nozzle (23) upwards towards the filter atomization mechanism (40).

A portable air filtration and disinfection device for a respirator system includes a casing, an inhalation filter assembly, and an exhalation filter assembly. The inhalation filter assembly includes an intake duct for receiving breathing air, an inhalation gas filter for filtering the breathing air, and an inhalation duct to provide the filtered breathing air. The exhalation filter assembly includes an exhalation duct for receiving exhaled air, an exhalation gas filter and an exhalation liquid filter for filtering and disinfecting the exhaled air, and an outlet duct for releasing the filtered and disinfected exhaled air.

The present invention relates to a disposable container (100). The disposable container (100) is use particularly for vaporization, evaporation or diffusion whereby filler materials of filler means are released into the air flow stream through air flow means. The disposable container (100) comprising filler means (101) filled with filler materials within the closed empty space between an inner side wall (101a) and an outer side wall (101b) and a top (101c) and a bottom part (101d) of the disposable container (100); and locking means (104) at the bottom part of the disposable container (100) to further secure the disposable container (100) to an air flow means. The inner side wall (101a), the outer side wall (101b), the top (101c) and the bottom part (101d) of the disposable container (100) are permeable or perforated enabling filler materials to be released into an air flow stream through air flow means; wherein filler materials are released by means of vaporization, evaporation or diffusion.

An air filtering and treatment apparatus (10), the apparatus (10) including: a housing (12) having an air inlet (14), an air outlet (16), an air passageway (24) between the inlet (14) and outlet (16), and a fan (18) arranged to urge air through the air passageway (24) between the air inlet (14) and the air outlet (16), wherein the housing (12) includes filter (20) arranged to filter air passing through the air passageway (24), and a receptacle (26) located toward the air outlet (16) relative to filter (20). The receptacle (26) is adapted to hold treatment composition (22) such that an evaporable vapour associated with the treatment composition (22) is able to accumulate in a headspace (41) of the receptacle (26), the headspace (41) including at least one aperture (36). The air passageway (24) may be shaped such that air flows substantially perpendicularly past the at least one aperture (36) of the receptacle (26) such that a pre-determined amount of the evaporable vapour is entrained into the filtered air released from the air outlet (16). A system (100) and method are also disclosed.

The invention relates to malodor masking compositions and/or ingredients, methods for counteracting or masking malodors, and perfuming compositions having odor masking properties comprising 2, 4-dialkyl substituted pyridines for formula (I).

Methods and cleaning compositions for reduction of nucleic acid contamination on surfaces, in air, and in solutions using modified pectin are provided.
