Abstract: An air cleaner includes a case, an air inlet, an air outlet, a grill covering the air inlet to filter airborne oil droplets, a fan to suction air through the air inlet and discharge air out of the air outlet, a roll filter provided between the grill and the fan to filter oil mist, and a filter roller to cut the roll filter. The roll filter includes a roller and a filter sheet wound around the roller, and the filter sheet may be unwound to extend behind the grill. When the filter sheet becomes dirty, the roll filter is further unwound so that a clean section is provided behind the grill, and the filter cutter may cut off the dirty section. During cutting, a clamp holds down the filter sheet. The case includes a slit through which the dirty section of the filter sheet passes for discarding.

Abstract: This present invention relates to a bacteria spread prevention tool designed to be used during oral procedures and is used to prevent the smear or spread of bacteria and viruses. The bacteria spread prevention tool comprises a slightly curved polycarbonic device having an interior suction mechanism. The prevention tool can be placed 4 to 6 inches from the oral cavity of a user, thereby forming a barrier between the user's mouth and the dental care professional, in order to prevent the spread of bacteria, or other pathogens via the oral cavity during dental health checkups or dental procedures. The transparent polycarbonic device provides access to the oral cavity while blocking the spread of aerosols and pathogens.
