CENTRAL AIR FILTERING METHOD AND APPARATUS
FIELD OF THE INVENTION
[001] This invention relates to air filtration and air purification.
BACKGROUND OF THE INVENTION
FIELD OF THE INVENTION
[001] This invention relates to air filtration and air purification.
BACKGROUND OF THE INVENTION
[002] Considered broadly, filters according to the invention are of the specific function type and come in various styles and designs. Currently filters or devices treat the passing air flow as units IN SERIES, by way of example; you could not have a quality inline air filter and also a quality HEPA inline filter mated to each other, in theory they would clean and purify the air flow going thru it however in practice their combined resistance factor to the air flow would cause the furnace to have its air flow volume severely curtailed by up to 75%, to the extent that its efficiency would be greatly hampered and most likely the furnace or air flow system in general would be overtaxed and its safety features such as the air flow sensors, and other sensors would cause the system to shut down for safety reasons.
[003] Filters are located within an air handling system may be either: an electronic air filter or a non electronic air filter such as the HEPA type and both systems may include the ultra violet light devices and other items or devices.
[004] The invention overcomes the problem of attempting to have a quality electronic air filter (EAF) in series with a quality HEPA filter by have the HEPA filter set back about 1" behind the (EAF) this set back airflow gap is critical to the operation of the invention not only does it allow the system air flow to actually by pass the HEPA
filter, do to the fact that air flow will always take the path of least resistance, in addition this set back airflow gap allows the (EAF) to load up with debris more evenly as the entire system air flow is actually being filtered by the entire (EAF) and not just a portion thereof. The "EAF"s media replacement pads are designed and intended to be replaced every approximately 3 months and are very inexpensive.

The "EAF"s media replacement pads are designed and intended to be replaced every approximately 3 months and are very inexpensive.
[005] The invention overcomes the necessity of having a HEPA Filter and its somewhat bulky cabinet positioned outside of the main air flow system in its own, stand a lone box with is two duct work tubes of up to 5 meters in length each thus saving on system air flow travel, this saves space and is much less costly for the consumer.
[006] The invention overcomes the costly replacement of the HEPA filter due to the fact of its unique position within the inventions box being about 1" behind the (EAF) and only occupying up to 50% of the surface area of the (EAF) the HEPA is only required it to treat up to 50% of the air flow passing thru the invention and relies upon successive air flow cycling of the re circulated air with the system to accomplish its efficiency.
[007] The invention overcomes its own restriction to the system air flow efficiency due to the resistance of its components by virtue of its own self contained and compensating air system booster fan also uniquely positioned within the box so as to be able to effectively compensate for its HEPA filter air flow resistance.
1008] The invention overcomes the need for larger and more costly ultra violet light (UV) systems that must be mounted somewhere within the duct work system before or after the system air fan with exterior control wiring for powering and controlling the (UV). Due to the fact of its unique position within its box and only occupying a very small amount of space the (UV) is only required it to treat up to 50% of the air flow passing thru the invention and relies upon successive air flow cycling of the re circulated air with the system to accomplish its efficiency.
[009] The invention is compact and houses devices that could not normally be used in the same manner as described within the invention and thus overcomes the need to purchase separate stand a lone filters and devices that when purchased separately would be more expensive than the invention.
[0010] The invention embodies all of its components in a combination of series and parallel configurations/placements and by-pass features to accomplish with in one "box" a compact air flow system internal air purification filtration by-pass system.
The invention relates to a unique combination and positioning of its system components.
[0011] The invention embodies its components in a novel and unique design that in stage one, filters and purifies 100% of all re circulating air in the most cost effective manner and in stage two, uses more costly items such as the HEPA and UV components in a special BY-PASS arrangement.
[0012] The method of air filtering and purification in stage two is intended to be accomplished over repeated air circulation cycles, this allows for smaller sized components still having the same efficiency ratios as larger units and also due to its smaller sizes the units cost less and the invention itself is very compact so as to be able to slide in between the furnace and cold air return ducting.
[0013] The invention is intended for re circulating force air system operations such as but not limited to residential, commercial, institutional and industrial applications.
[0014] The invention is intended for stand a lone air filtration units (or combination thereof) that are used for non system force air operations such a individual room units, portable units and in general any application whereby the invention can be used to fulfill its operations.

off all system incoming air flow and consists of three internal parts the outer media filter the centre charcoal grid and the exit media filter; item #5 is the approximately 1" air gap space that separates the electronic air filter and the HEPA Filter. This set back gap of about 1" between the two filters allows the Electronic Air Filter to load up evenly with debris. The HEPA filter life span is increased from about one year up to 3 years, so it is beneficial replace the less expensive electronic air filter media pads every three months as they are a very inexpensive item as compared to the HEPA filter. Item #6 is the HEPA
filter that is the same height as the electronic air filter however it has only about 50% of its surface area. Item #7 is the ultra violet lamp twin bulb; it is situated behind the electronic air filter and in the adjacent cavity void of the box.
