Air treatment device

Abstract

An air treatment device is described that comprises: a housing having at least one air inlet and at least one air outlet with at least one air passageway therebetween; at least one fan located within said at least one air passageway; at least one air filter retaining means arranged to releasably retain, in use, an air filter within a passageway; at least one refill securing means arranged to releasably securing a refill of air treatment agent within the housing; emanation means within the housing; and wherein the housing is provided with a door to permit access to at least said air filter retaining means; and wherein the air filter retaining means are configured to move from a first position when the door is closed in which the air filter substantially completely obstructs said at least one air passageway to move to a second position when the door is open such that the air filter no longer substantially completely obstructs said at least one air passageway.

Description

technical field [0001] The present invention relates to apparatus for treating air, especially but not exclusively for treating air to remove pollutants and / or deodorize air and introduce air treatment agents to air. Background technique [0002] The increasing amount of indoor air pollution involves possible impacts on human health. Some studies suggest that indoor air is significantly more polluted than outdoor air, which may be especially relevant because people spend most of their time indoors. Therefore, the air in the local environment is treated by striving to remove some of the more prevalent indoor air pollutants including dust, smoke, pollen, bacteria, soot, mold spores, animal dander, and other subtle irritants, as well as by striving to deodorize It has thus become increasingly desirable to improve not only its perceived quality, but also its actual quality, and thereby create a clean, healthy, fresh and pleasant environment. [0003] Air-purifying devices are ...

AI Technical Summary

Problems solved by technology

[0003] Air-purifying devices are widely known, and while such devices are believed to improve actual air quality, it is difficult to convince consumers that they are particularly effective because such devices often do not significantly improve perceived air quality

[0004] On the contrary, aromas are known to be effective in improving the perceived air quality, but this is not particularly effective from a consumer point of view, mainly because the air quality is compromised in the first place, for example during the deodorization process.
