Abstract: An air purifier, an air filter and a method of manufacturing an air filter for an air purifier are provided. The air purifier includes a base assembly, a filter assembly and a grill. A fan is mounted to the base assembly, and draws air through the filter assembly. The base and filter assemblies include adjoining walls having openings which are substantially smaller in area than the areas of the adjoining walls and area through which air is drawn in through the filter assembly. A resilient gasket having a passage approximately the size of these openings is positioned between the adjoining walls. The filter assembly is drawn towards the base assembly when the fan is operated, thereby enhancing the seal formed by the gasket against the adjoining walls. Unfiltered air is accordingly unlikely to bypass the filter assembly. The air filter is manufactured in an efficient manner through the use of a back plate having oblique end portions.

Abstract: A lamp with improved safety features to avoid fire and burn hazards. The lamp includes an electrical circuit having a thermostat connected in series with the bulb of the lamp. The thermostat is mounted in close proximity to the lamp's bulb and, upon the ambient air temperature in the vicinity of the thermostat reaching a predetermined temperature, the thermostat effectively opens the electrical circuit, shutting the lamp off. Once power is turned off for a period of time, the thermostat resets and the lamp may be operated again. A protective guard is positioned over at least a portion of the bulb of the lamp to prevent accidental burning.

Abstract: An evaporative humidifier includes a base having a portion defining a reservoir for holding a quantity of water. A housing is mounted on the base over the reservoir, the housing having an air inlet and an air outlet. A cylindrically shaped wick filter with a permeable support is seated in the reservoir and extends up into the housing. The cylindrically shaped wick with permeable support filter has an open top end and a sidewall. A color change indicator strip is provided on the inner portion of the sidewall. The color change indicator strip provides a signal when the filter requires changing due to the extent of use and immersion of the filter in water. A fan is mounted inside the housing for drawing air into the housing through the air inlet, then into the center of the cylindrically shaped wick filter through the open top end, then out through the sidewall of the cylindrically shaped wick filter with a permeable support and then out of the housing through the air outlet.

Abstract: An easy-assembly dual-pole floor lamp includes a first pole with top and bottom ends and a base portion which is secured to the bottom end of the first pole. The base portion has a lower second-pole-receiving region, and a second-pole-mounting member is secured to the first pole at a predetermined distance above the lower second-pole-receiving region of the base portion. The second-pole-mounting member has an upper second-pole-receiving region. The lamp also includes a second pole which has a top end and a bottom end. The top end is configured to mate with the upper second-pole-receiving region, and the bottom end is configured to mate with the lower second-pole-receiving region. The length of the second pole is adjustable over an adjustment range which extends at least between first and second values; the first value of the length is selected to permit easy insertion of the second pole between the upper and lower second-pole-receiving regions.

Abstract: A humidifier includes a base unit defining a reservoir for retaining a liquid. A liquid supply tank is also provided which is supported by and positionable within the base unit. The tank further includes an aperture defined by an aperture wall disposed on the top wall of the tank in order to permit the liquid to be introduced into the tank. The humidifier also includes a plug assembly having an outer diameter dimensioned for being insertable into the tank aperture. The plug assembly has a mechanism for increasing the plug's outer diameter. Such that when the plug assembly is inserted in the aperture, actuation of the mechanism for increasing the outer diameter urges the plug assembly against the aperture wall thereby sealing the aperture.
