[0035] DETAILED DESCRIPTION OF SPECIFIC EMBODIMENTS

[0036] An air filtration system in accordance with the present invention incorporating moss in a modern and visually pleasing, biophilic design to treat and filter particulate matter (PM2.5 and PM10), CO2, volatile organic compounds, bacteria, and viruses, as well as other harmful chemicals that impact the environment and human health is provided. The system can be used in both indoor and outdoor settings, and along walls or the side of buildings.

[0037] A certain species of moss must be first selected. According to a method of the present invention, moss species that grow in sheets or mats, which are known as Pleurocarpous moss, or mosses that grow in clumps, such as Acrocarpous moss can be used. Pleurocarpous moss examples include mosses in the Genus Hypum, and Thuidium, while an Acrocarpous moss example includes the Genus Leucobryum and Dicranum. These mosses are preferably selected as they are slower growing than most mosses and do not require as much water as most mosses. Other species of mosses can be also used in this invention and contain a combination of different species of moss. The moss can be live, preserved, or dormant, or combination thereof (such as a combination of live and preserved moss, for example, or a combination of live and dormant moss, etc.). The moss can be preserved in glycerin and water, for example.

[0038] Mosses are sustainable under certain environmental conditions such as sunlight, humidity (60% to 80%), moisture, pH (5-6) and temperature (60 degrees Fahrenheit to 80 degrees Fahrenheit). Selecting the engineering design of the invention to keep each environmental condition needed for each moss type within ranges is crucial to sustaining the moss. Since mosses are nonvascular and do not contain roots, they need a substrate in which to receive nutrients and water to keep within the needed environmental conditions. A strong physical connection or bond between the moss and substrate is also needed for the moss to be sustainable in its environment. According to the embodiments of the present invention, different species of moss can have a combination of varied substrate material needs, such as a flat, water absorbing and retentive substrate, or a combination of composites or acidic substances to ensure the pH range in its environment.

[0039] As shown in FIG. 1, the air filtration system of the present invention includes a base layer 1, a substrate layer 2 and a plant layer 3, which can be live, preserved, or dormant moss, or combination thereof. A substrate shall be used that is a water absorbing or retentive material to keep moisture content within the needed range, such as felt, wool, fabric, soil, cloth, rock, stone, wood, or a sponge. A strong physical connection or bond between the substrate and moss is needed for the moss to be sustainable. The substrate and moss are connected directly to a wall or to a base material. According to some embodiments of the present invention, the base material can also be the substrate. Thus, the air filtration system can include a substrate and a plant layer and no base layer.

[0040] The base can be made of water resistant material and/or anti-corrosive material such as plastics, PVC, metal, or composite aluminum, metal alloys, galvanized steel, or stainless steel. Or it can be made of a non-water resistant material, such as wood and painted with a water resistant paint or adding a layer of water resistant material such as a sheet or film. The base material can be of varying sizes and depths (such as a rectangular, square, or circular recessed unit as shown in FIGS. 5A-5B and 6-9, for example), a frame tray, or combination of, that can be used as a decorative unit and held up either vertically or horizontally on such furniture as desks and tables. The base can also be a sheet, frame, panel, or a modular panels that can be attached and connected to fill an entire wall both as a standalone unit as shown in FIG. 8, or as interlocking units that connect along a wall or building as illustrated in FIGS. 10A-10B. In some instances, the system can have a modular design including a plurality of detachable panels. In some instances, the panels can be attached to each other permanently.

[0041] The base can be combination of water resistant and non-water resistant material. Recycled material such as reclaimed wood or recycled plastic can be used as the base material. The base material can also be a combination of materials such as a wood-poly composite. The unit can be open or closed off in the front with a material such as plastic, glass, or Plexiglas, and an open space at the top of the unit for ventilation. The unit may have perforations within or outside the base for optimized air flow.

[0042] The substrate can include antifungal materials which can also be added to the design to increase the substrate and moss bond, air filtration properties, and protect the moss from mold, fungus, and other organisms. Antifungal components may be natural ingredients such as essential oils, garlic, coconut oil, aloe vera, apple cider vinegar or a combination to ensure substrate properties are within environmental conditions of the moss. In some instances, antifungal foam sheets or panels can also be used for the purpose.

[0043] According to some embodiments of the present invention, the air filtration system can also include one or more netting layers. As illustrated in FIG. 2, the system can include a base, a substrate, a first netting layer, plant medium such as moss, and, optionally a second netting layer.

[0044] In some instances, as shown in FIG. 3, the system can include a base layer, a first netting layer, a substrate, a plant medium such as moss, and optionally a second netting layer. This combination can be created by first laying down an initial layer of the netting, next laying down the substrate on top of the netting, applying the moss to the substrate, and applying a second layer of netting. This moss, substrate, and netting combination can then be attached as is to the base, securing the combination into place.

[0045] Materials such as bird netting, a poly and wood composite, trellis, metal or wire can be used to keep the moss in place, and further the connection between the moss and substrate. It will be appreciated by a person skilled in the art that other materials that will enhance the physical bond between the substrate and moss can also be used.

[0046] According to some embodiments of the present invention, as illustrated in FIG. 4, the system can include a base layer, a first netting layer wrapped around a substrate layer and plant medium layer such as moss. This combination can be created by first laying down a first extended netting layer, next laying down the substrate on top the first extended netting layer, applying the moss to the substrate, and wrapping the extended initial netting layer around the substrate/moss layer. This moss/substrate/netting combination can then be attached as is to the base, securing the combination into place.

[0047] In accordance with the methods of the present invention, the method making an air filtration system can include the following steps. Step 1: Place down a layer of the netting. Keep more than the needed amount or keep the entire roll intact so that it can be wrapped around the other layers to seal the entire combination. Step 2: Place the substrate on top of the netting. Step 3: Place the moss on top of the substrate and netting. Step 4: Either a second layer of netting can be applied or the initial, extended netting can be wrapped around the substrate and moss and on top of the initial layer of netting as illustrated in FIG. 4. The newly formed netting, substrate, moss layer can be sealed by affixing the outer edges of the two netting layers and attaching this unit to the base material, or by directly attaching the entire unit as is to the base material. In some other instances, the method includes the step of first applying the substrate to the base. The moss is then applied to the substrate. The netting is then attached to the substrate or base, securing the layered combination into place.

[0048] In some instances, the moss can also be affixed to the substrate or base using an adhesive without the use of netting. Organic based adhesives, cyanoacrylate gels, plastic glues, and silicone-based adhesives can be used.

[0049] The live moss may or may not require watering as the substrate layer is designed to contain water for the moss. If the moss does require watering, it can be done manually or by employing a watering system. The air filtration system of the present invention can also include a watering system as illustrated in FIG. 11, for example. The unit can contain a water reservoir, which is connected to a duct system. Water can be gravity fed from the top of the unit to the bottom of the unit, through each duct-tubing layer. A drip irrigation technique of installing tubing as the duct system and installing additional misters or sprinklers to provide water to the unit while ensuring water conservation. The watering frequency can be done either manually or automatically using a timer or sensor, which would also ensure water conservation. A catch basin can be installed at the bottom of the unit to collect excess water. In salt water habitats, spring water, distilled water, or recycled water such as storm water (runoff or snowmelt) or condensation from HVAC units can be collected and used to water the system, as moss does not thrive well in salt water environments. In some instances, the system can also include a water pump connected to the water storage reservoir, and optionally to the catch basin.

[0050] If the system is automated, it can have pressure-compensating emitters, to maintain constant pressure throughout the duct system. The timer and emitters can be connected to a main controller, which may be controlled by a mobile app. Flow sensor(s) may be installed and connected to the main controller to conserve water usage and ensure the moss and plants are getting the adequate amount of water. A main system controller can be installed to control and measure water temperature, water flow, water pressure, air pressure, air flow, and other factors. A CO2, humidity, and O2 sensors may also be installed throughout the unit. The controller may be connected and powered using a mobile app.

[0051] The air filtration system of the present invention can also include an air circulation system as illustrated in FIGS. 12-15. To increase the rate of filtration of harmful pollutants, and to keep humidity levels within range, a fan can be installed and provide a current through ducts to the unit so that the polluted air flows through the moss as the media, and clean air is discharged from the unit. The air filtration rate of the moss can be increased by increasing the airflow rate of the air throughout the unit. The greater the airflow velocity, the higher the filtration rate.

[0052] The air filtration system can either be passive, using only one fan, or active, utilizing more than one fan. In the simplest case of more than one fan being installed, there will be an inlet fan, allowing air through the system, and another fan at the outlet, helping to discharge air. If needed, more than one fan can be installed throughout the unit to allow air to flow through the plant medium, as illustrated in FIG. 15, for example. The efficiency of the fan(s) can be increased, and friction decreased by decreasing the length of the ducts and by increasing the diameter of the ducts. This also prevents clogging of the duct line and subsequently, overheating of the fan(s). The polluted air flows through the moss as the media, and clean air is discharged from the unit. Although the greater the airflow velocity, the higher the filtration rate, it is important to not directly surge the moss with an air current as it may cause damage to the moss and its leaves. In order to decrease strain on the fan, a timer may be installed so that the fan is not on at all times.

[0053] The air filtration system can include the watering system as described above and illustrated in FIG. 11 or the air filtration system as described above and illustrated in FIGS. 12-15, or a combination of both systems. In some instances, the air filtration system can also include a lighting system comprising one or more LED lights as described above and illustrated in FIG. 23. According to another embodiment of the present invention, the air filtration system can include a UV light source disposed in the base or frame of the system and configured to kill bacteria.

[0054] The biophilic design aspect of the invention elevates sensory input in innovative approaches and therefore reduces stress and anxiety and improves productivity. By including moss with the combination of 3-D designs, natural materials such as wood, and activation of sensory input such as sight, touch, and smell from the invention elude being in nature and also aid in therapeutic relief. For example, spray bottles, ergonomically selected and or designed for every hand type, is provided with the invention, spray misting the moss is calming and emits an evergreen smell like fresh grass all inside an outdoor environment. The invention can also include speakers or music, which is not just calming for people but for the moss as well, as moss is known to absorb sounds.

[0055] Moss is a sufficient air filter on its own. However, one or more layers of commercial air filters of different materials and targeted compounds may be used in synergy with the moss to optimize air purification, as schematically illustrated in FIGS. 20-21. They can either be separated from the moss or attached as part of the moss and or substrate layer. The different layers can be stacked in an interlocking chamber, where they can be removed and installed easily. One or more filters may be biodegradable to avoid waste. The filters may be commercially available filtration media of different materials, pore sizes to target specific compounds. The filters can comprise a multi-layered structure having different filter media in a sequence. In some instances, the filter can be a carbon filter configured to filter volatile organic compounds (VOCs) such as benzene and the like. In some other instances, it can be a bacterial filter characterized by a certain merv rating and configured to filter bacteria and viruses. Each type of filter or both can be used in combination with the moss filter thereby creating a synergetic effect.

[0056] A medium downstream of the moss and filter may be used to capture particles and compounds captured by the moss and filter layers. Air will be introduced in an inlet and outlet fashion, going through the different layers of filters, including the moss.

[0057] The housing of the filter or base unit may be made of metal, glass, plastic, composite aluminum, metal alloys, galvanized steel, or stainless steel, or any other suitable materials, but the metal preferably should not make direct contact with the moss as it can deplete the watering source for moss and cause harm to the plant medium such as live or dormant moss. In some instances, the metal present in the substrate could also cause harm to the plant medium even when the moss is not in direct contact with the substrate, thus the substrate should be substantially devoid of metal, according to another preferred embodiment of the present invention.

[0058] The air filtration system of the present invention can have various configurations wherein the filtration medium such as moss is arranged in one or more patterns. The base can have a raised structure with the moss arranged in a zig-zag pattern, as illustrated in FIG. 16, for example. In some instances, the moss can be incorporated into a frame having handles as illustrated in FIG. 17. According to some embodiments of the present invention the base can include a three-dimensional (3D) structure forming a wavy patterns with filtration medium such as moss incorporated into cavities as shown in FIGS. 18A-18B. According to some embodiments of the present invention, the system can form a raised three-dimensional (3D) structure comprised of separate panels, as illustrated in FIG. 19. In some instances the raised structure can be integrally formed as one piece as opposed to being built using separate panels. The air filtration medium such as moss can be incorporated into frames having various shapes. In some instances, the moss can be incorporated into a recessed rectangular frame as illustrated in FIGS. 22A-22B or into a frame having a lantern-like configuration as shown in FIG. 24, for example. In some instances, the base can be a 3-D printed structure made by virtue of 3-D printing technology, and further have compartments to house the fan, watering system, filters and other suitable components.
