There has long been an unmet need for a means to filter indoor house air for health reasons and for odor reasons but the state of the art is lacking in many ways. Traditionally, home owners use dust filters to perform house odors cleaning, however, such home ventilation technologies still permit an undesirable odors and chemical contaminants through the surrounding environment of the home owner. As such, there is a need for a technology that solves the above mentioned problems with tightly sealed houses.
The present invention is a device that suspends activated charcoal to filter the air in a column. Allows convenient replacement by downwardly removing the insert when changes are necessary.
EXAMPLE: This invention relates to an air filter vessel and more particularly to an air purifier mounted in the middle of an air chamber register of a whole house air inlet return grille.
The invention relates to vacuum-fed filtration system, and more specifically to a vacuum-fed air filtration system.
The rectangle charcoal air filter is carried on top of a dust filter which seals the inlet surface. The filter can be rectangle, square, or any other shape type without limitation that causes the activated charcoal to be suspended in the air column by a mesh structure. The position of the filter allows the upward airflow (vacuum) of the ventilation air current to suspend the activated charcoal in the air column. The bottom grill door is opened and the dust air filter is removed and the charcoal air purifier is placed on top of the dust filter and reinserted in the ceiling air inlet air return grill. A new charcoal purifier filter can easily be installed and repositioned in the operating position.
Incoming air flows through openings in the screen bottom and top of the mesh of the charcoal air purifier. Increasing the air flow increases the amount of purified air. From the air chamber, air flows through the ventilation unit and then into the room vents. (
In this rendition, the activated charcoal bed is levitated by a vacuum but can also be levitated by all sizes and shapes of fans without limitation blowing straight up the bottom of a mesh structure. This includes fans that can create a vacuum above the mesh structure with a reverse fan setting instead of blowing air.
The rectangle activated charcoal filter is located above the dust filter and inlet port receives the filter as shown in
The filter operates in the following described manner Referring to (
A new activated charcoal filter element (1) can again be reinstalled on top of the dust filter after removing the old activated charcoal air filter above the dust filter.
Air Duct Activated Charcoal Air Filter Assembly
Background: In the present world of ceiled homes with attendant pollution from chemical cleaners and odors, the need exists to provide extra precautionary means to insure that the air to which one is exposed is close to pure air as can be, even when living in a home.
This invention relates to an improved, easily replaceable air filter assembly as applied to the return grille of a ducted home air system. More particularly, the invention is directed to new improved manner of filtering return air that is directed into the interior of a home or building through its air conditioning, heating, and ventilation systems and includes an enclosed floatable bed of activated charcoal.
The return air grille sucks the air up through the dust filter and then through the activated charcoal filter which suspends the loose charcoal in the air column and cleans the polluted air. The object is to increase the supply of cleaned air to the interior rooms of a home, building and RV which provides control and regulation of the returned air.
A vacuum caused by the ventilation system can supply relatively large volumes of air into the interior rooms. The activated charcoal air purifier element will filter the interior air entering the return grille.
This filter system provides an inexpensive improved home air filter/air purifier device that can easily be adapted for use in a new as well as older home. Another object of this invention is to provide an improved device for ventilated air to a home to neutralize contaminants, odors or gases. The invention also provides an improved filter device to easily mount an air cleaner after the dust filter.
