Description of Related Art

HVAC stands for heating, ventilation and air conditioning system, it provides heating and cooling to residential and commercial buildings. These systems use fresh air from outdoors to provide indoor air quality throughout the process of ventilation which replaces or exchanges the air within a particular space, it involves the removal of moisture, smoke, odors, heat dust, airborne bacteria, carbon dioxide, and other gases such radon, it also provides control of temperature and oxygen.


In general, the HVAC system is comprised of nine elements: Air return, Filter, Exhausts outlets, Ducts, Electrical elements, Outdoor unit, Compressor, Coils and Blower. The Air Return is the part of the HVAC system that marks the starting point of the ventilation cycle. This return sucks in air, draws it through a filter, and then passes it into the main system.


The filter is the second part of the air return in which the air is drawn through.


The exhaust outlets are where the exhaust created by the heating system is expelled.


Ducts are the channels in which the heated or cooled air passes through.


Electrical components such a thermostat or a braker.


The Outdoor Unit houses the fan which provides air flow.


The Compressor is responsible for converting refrigerant from a gas to liquid and sends it to the coils.


Coils cool the air as it passes through with a little help from the refrigerant.


The Blower draws in warm air through the main section of the unit.


Nevertheless, after HVAC system is installed and working properly, the reality shows that the indoor air quality is directly dependable on the Air Filter.


Great variety of air filters already exist that help to capture varying sizes of particles such as: lint, pollen, dust, pet dander, dead skin cells, smoke, smog, cough and sneeze particles, bacteria, virus, candle soot and air pollution in general.


The three air filter rating systems differ in ranges and were created by separate organizations.


MERV ratings extend from 1 to 16.


MPR measures ratings based on sizes 0.3 to 1 microns.


FPR ratings are on a scale from 4 through 10.


The MERV filter rating is the domestic and international industry standard rating system established by the American Society of Heating, Refrigerating, and Air Conditioning Engineers. The other two systems were created by “3M” (MPR) and “The Home Depot” (FPR) to differentiate their offerings.


However, a challenge with before mentioned system is that the indoor air quality depends on the efficiency of the Air Filter which depends on the quality and specifications of the filter itself, but its effectiveness is dependent on the frequency in which this filter is replaced.


Another challenge is that traditional HVAC filters are problematic to access and difficult to replace. The fact that they are hard to view makes it easy to forget about them and the well-timed and adequate replacement becomes compromised.


Another challenge is that the indoor air quality oft the whole house depends on a single air filter since most HVAC systems only required a single filter per unit that typically is located at the Air Return.


The HVAC system can be working properly but if the filter is saturated with excess of particles and contaminants, sooner or later these particles are returned into the ducts and reexpelled into the living areas and a cycle of indoor air contamination sets in motion. Thus, a greater problem is created and characterized as significant risk to the public from indoor environmental contaminants that are commonly found in homes, schools, offices and commercial buildings.


Most Americans spend 90 percent of the time indoors, even more so during COVID-19 Pandemic.


The United States Environmental Protection Agency has identified that the levels of indoor air pollution are often two to five times higher, and occasionally 100 times higher that outdoor levels. It estimates that the economic cost associated with adverse health and productivity effects of poor indoor air quality fall between $13 and $32 billion annually. Lung cancer, Asthma, and Allergies are the most common diseases associated with indoor air pollution.


Additionally, clogged air filters increase energy consumption by 5 to 15 percent. Therefore, it is evident that what is promptly needed is an external air filtering system that easily attaches to the existing air vent that solves the above limitations.


In some cases, a filter material in the form of roll is known which can be glue or attached to the air vent still remains impractical because it has to be cut to fit vent and can be easily detach causing problems to the user, therefore it does not solve the aforementioned problems.


Furthermore, the purpose of the present invention in addition to filter the air before it enters a room, it is also to impregnate with a fragrance or essential oils if the user decides to do so.


US Patent No.: 2010/0227545A1 Discloses an air vent cover and filter that is affixed to a frame that is attached to the flat portion of the air vent. The purpose of this invention is to filter the air before it enters a room, it also can be impregnated with a fragrance however, based on information available of such invention, it does not solve the problem of hassle-free operation and is not aesthetically inconspicuous. Additionally, it does not offer the capability of using different types of filters for customization of indoor air quality depending on the needs of a particular living area according to homeowner's desire.


BRIEF SUMMARY OF THE INVENTION

The problems previously stated make difficult for houses, schools, offices and commercial buildings to enjoy of clean and unpolluted indoor air.


A strong need exists from homeowners, schools, offices and commercial buildings with a central air system, to have the option for an external air filter system that can aid to prevent dirt and dust particles that are circulating throughout the home and have infiltrated to the ductwork of the house, from reentering into the living spaces, therefore polluting the air that their dwellers breath.


In like manner a strong need exists from homeowners, schools, offices and commercial buildings with a central air system, to have the option for an external air filter system to to have the option to customize the intensity of the air filtration on each individual living area where an air vent exists by choosing specific air filter capabilities according to the desired level of filtration.


In like manner a strong need exists from homeowners, schools, offices and commercial buildings with a central air system, to have the option for a fragrance of choice carrier system that can aid in delivering such fragrance into a room or living space of choice. Even more so, the present COVID-19 Pandemic urges for a system that can help to improve the indoor air quality by minimizing the pollutants that enter a living space. The present inventor realized in an inventive moment that if, an air filter could be placed on each air vent, air filtration could be optimized by adding air filtration sites throughout the home instead of exclusively relying on a single air filter for the whole house. The inventor therefore constructed a rectangular frame fixture, with an opening where air filter can be inserted, the inventor realized that the present invention was not a replacement of the regular air filter link to the HVAC System, furthermore the invention, was an excellent complement to the existing HVAC System. The inventor concluded that both air filtering systems one internal and the other external could work in a synergistic way enhancing the quality of the indoor air, The inventor realized in an inventive moment that the relationship existing between both air filtration systems was observed in nature, most commonly between a shark and a remora fish, therefore the inventor determined that the big central unit filter could be referred as a shark and the small external filter could be referred as a remora fish, therefore the inventor decided to name his invention Air Vent Remora, however the present invention can also be referred simply as a filter holder.


Accordingly, strong magnets were embedded on each side of the back of the frame fixture to attach it to the flat surface of an existing air vent, although other methods for attaching the air vent fixture can be used such as suction cups, adhesive materials or screws.


According to one aspect of the present invention, the face or front of the filter holder, is designed to look like a regular air vent to appear inconspicuous to the eye and non-alter the aesthetics of the living area where it is placed.


Another embodiment of the present inventions is comprised of a custom fitted air filter that easily is inserted into the filter holder.


Yet another embodiment of the present inventions is comprised of a custom fit filter like absorbent fabric material where the fragrance of choice or even essential oils can be dispersed throughout the absorbent material so it can be diffused into the air of the living space of choice.


The present invention is shown in a rectangular shape, since most common air vents are rectangular in shape, however it can be conformed to a circular or a square shape as well, to fit the different air vent shapes.
