BACKGROUND OF THE INVENTION
Field of the Invention:
There are numerous devices known to atomize a liquid and deliver into the surrounding air. Devices such as other vaporizers provide introducing to air various types of solutions in order to vaporize the solution and introduce it into the air in a room or habitable structure. Most of these devices focus on scenting, purifying, or humidifying air.
Other devices require a timer or are manually to be turned on or off with a switch.

ak 02898168 2015-07-21 There is a recognized need for a device configured to automatically atomize and deliver a solution to a specific volume of enclosed space while accounting for concentration of a delivered solution in a functional relationship based on the interior volume.
SUMMARY OF THE INVENTION
The present invention relates to an air-aerosol dispersing apparatus, which can work on its own as well as in conjunction with an HVAC system.
In one embodiment, the present invention relates to a pre-selected solution mixed with pro-biotic bacteria that is released into the air. The release is by the atomization of a solution mixed with pro-biotic bacteria that can be added to the air via the HVAC system, directly into a room, or combinations thereof. Prior devices are deficient in they all lack the quantitative measurement and usage of a functional amount of pro-biotic bacteria.
In one embodiment, the present invention has an at least one airflow sensor configured to eliminate user input. The airflow

2 ak 02898168 2015-07-21 sensor will activate the device, as it will sense airflows as a result of the operation of an HVAC system.
In one embodiment, the present invention includes a microcomputer interface for programming the intervals and length of time the device will turn on each time. This enables the present invention the ability to perform independently from the HVAC system as desired.
In one embodiment, the present invention is a system and method configured for delivery of a measured and effective amount of a biologically functional solution into the air, HVAC system, or combinations thereof. In one embodiment, a pro-biotic bacteria solution is atomized light enough and carried by the airflow and pressure differential in HVAC systems.
In one embodiment, the mist itself is a Stabiotic(p, which is a blend of pro-biotic bacillus strains of bacteria that have been stabilized and are also in spore form. Once the Probiotic is exposed to the mixture of water and/or air it becomes active.
Upon contact with any particles in the air or on any surface, they immediately consume sustenance, allergens and other contaminants, thereby cleaning to the microscopic level and further deconstructing biofilm; thus providing an extremely

3 ak 02898168 2015-07-21 effective way of cleaning and thus reducing the risk of infection.
In one embodiment, the adaptive device is configured for positioning on the ground, inside HVAC systems, on counter tops, or mounted on the wall. The device has interchangeable solutions so that the user can change and refill the removable bottle. The device will perform without the user having to interact with the apparatus on regular basis and does not require it to be switched on or off, allowing for a more automated operation.
In a preferred embodiment, the present invention is configured to incorporate delivery with a solution container engineered to receive compressed air and directing the air in the container to impart a venturi effect into a closed chemical container that contains the delivery solution. By pressing the air under pressure into the delivery solution chamber, the solution is atomized and directed outward through a configured outlet. The atomized solution air is directed into an exit hose to the outside environment.
To the accomplishment of the above, the invention is illustrated in the accompanying drawings. Attention is called to the fact, however, that the drawings are illustrative only. Variations are

4 ak 02898168 2015-07-21 contemplated as being part of the invention, limited only by the scope of the claims.
It is an object of the present invention to have a system and method for atomizing a solution with at least one active component and delivering the atomized solution to an interior area of a structure in direct delivery to the interior atmosphere, delivery through a HVAC system, or combinations thereof.
In one embodiment the active component is a Probiotic, pharmaceutical medicament, or nutritional supplement.

Additional features include configurations with control abilities via RF or similar to control the device via

5 ak 02898168 2015-07-21 smartphones, computer, remote, to see the environmental situation and device battery and/or cartridge levels.
The present invention can be configured as a portable device used in an office, bedrooms, camping, living rooms, automobiles, airplanes, and any indoor or outdoor location. Optionally, the system is configured with a personal spray nozzle where one can spray oneself.
The microcomputer interface is programmable with the ability to program the device to work by time / environmental condition.
The system and method of the present invention will assist in fixing SBS - Sick Building Syndrome, by reducing the amount of bad germs in the building space, and by that increasing vitality.
The system also has a sensor that checks not only the quality of germs in the air but also a sensor that senses the movement of air, so as soon as the HVAC system turns on, the device senses it and turns itself on accordingly to dispense mist, this way there is no wasted solution material. This also disables access liquids to be in the HVAC while not working, which would cause more bacteria, enables a better usage of material.

The system and method of the present invention is unique in that sensors are configured to actuate itemization of a delivery solution based upon particularized measurements.
In one nonlimiting example, the sensors are configured using the standard index of microbial air contamination (IMA). As is known in the art, the standard index of microbial air contamination (IMA) for the measurement of microbial air contamination in environments at risk is described. The method quantifies the microbial flow directly related to the contamination of surfaces coming from microbes that reach critical points by falling on to them. The index of microbial air contamination is based on the count of the microbial fallout on to Petri dishes left open to the air according to the 1/1/1 scheme (for lh, lm from the floor, at least lm away from walls =
or any obstacle). Classes of contamination and maximum acceptable levels have been established. The index of microbial air contamination has been tested in many different places: in hospitals, in food industries, in art galleries, aboard the MIR
space station and also in the open air. It has proved to be a ak 02898168 2015-07-21 reliable and useful tool for monitoring the microbial surface contamination settling from the air in any environment.
In order to combat microbial growth, an anti-microbial probiotic solution is used in the system and method of the present invention. As will be set forth below, laboratory testing has demonstrated the delivery of atomized probiotic using the system and method of the present invention has been proven to reduce live microbial species.
The Sensor may cause the system to turn on / off according to the environmental condition result.
The actuator initiates air into the solution container, and the solution is atomized by a venturi effect and exits the solution chamber. The atomized solution is then directed as desired from the assembly TESTING AND RESULTS

= Control (0) = 24 Hours = 48 Hours = 72 Hours f) The collected samples were packed and shipped according to the environmental laboratory requirements.
Results Collection of samples from the main filters of an AHU (Air Handling Unit) and analyzed the results at a certified accredited and registered environmental microbiology LAB.
Summary The results we obtained by using BioZone Probiotics/EBA on two main filters of AHU were excellent and encouraging.
As demonstrated in FIGS 15-22:
FIGS 15 and 16 demonstrate quantified amounts of cladosporium and penicillium before use in the order of approx. 38,000 to 84,000 fungal counts in CT/cm2.

ak 02898168 2015-07-21 FIGS 17 and 18 demonstrate after using an atomized probiotic delivered with the system and method of the present invention, the measurements dropped to NFD (no fungi detected) in 2 locations and 100 count/cm2 in the bottom right of the tested filter.
FIGS. 19 and 20 demonstrate quantified amounts of cladosporium, alternaria, and aspergilus, before use in the order of approx.
40,000, 2,000, and 78,000 fungal counts in CT/cm2.
FIGS 21 and 22 demonstrate after using an atomized probiotic delivered with the system and method of the present invention, the measurements dropped to NFD (no fungi detected).
The results confirm suitability of the system and method of the present invention for the use of environmental Probiotics for an efficient control of microbial (Bacterial/Fungal) growth.
The results further indicate that the system and method of the present invention would be suitable on a variety of objects such as fomites, textiles, construction materials and a variety of porous and semi-porous materials, and similar to those in hospitals, under similar environmental conditions such ak 02898168 2015-07-21 as; air temperature and relative humidity (40% - 50% relative humidity and 1Soc- 22 c Air temperature) It is further contemplated that the present invention be configured to program the unit at initialization based on size of space (cubic volume) and initial level of contamination (where known or estimated).
Additionally, if future technology advances to provide real-time testing of microbial activity, the present invention is suitable for use with such testing.
Additionally, the present invention is unique in that the mechanical process of solution atomization uses the Venturi effect.
The present invention requires care with the 2 venturi channels in order to make it working as you have to have 2 narrow channels or pipes into a container one to push air in and one to have the liquid broken to tiny droplets (atomization).
Currently, since the venturi components must be very narrow in diameter, providing a replacement cartridge is cumbersome as one needs to ak 02898168 2015-07-21 unscrew a cap and carefully take the whole nebulizer without breaking or bending and place a new one.
The present invention configures the system for easily replacing a sophisticated cartridge that has this mechanism built in in every cartridge that make it easier for replacement.
The solution cartridge has the nebulizer siting in a cap holder of the cartridge - a fixed part that never to be replaced.
The "connection" is achieved by very accurate mechanism that ensure that the sliding cartridge meets its matching pipe by touching which requires accuracy to level of more than 1/10 mm The present invention is a mechanical improvement of the Venturi system for the consumer market, indirectly creating very inexpensive cartridges It is further contemplated that the system and method of the present invention be used for the wide administration of an inhaled medicament, for example, a hospital has an outbreak of a bacterial infection, and an antibiotic can be atomized and distributed throughout the entire building.

ak 02898168 2015-07-21 As previously discussed, the method of delivering solution according to the present invention requires consideration of solution concentration, air volume of the room or rooms effected, and desired final concentration of atomized solution.
While the invention has been described in its preferred form or embodiment with some degree of particularity, it is understood that this description has been given only by way of example and that numerous changes in the details of construction, fabrication, and use, including the combination and arrangement of parts, may be made without departing from the spirit and scope of the invention.
