Problems solved by technology

This often requires a laborious and time-consuming process of removing and reattaching the filter to the ventilation system using fasteners, clamps, duct tape, etc.
This is especially difficult when the filter unit is located in a hard-to-reach area such as a ceiling mount
The inability to recycle or reuse parts of the filter unit also increases the material cost of maintaining such filters
Therefore, the user's time, material and labor costs are high

Embodiment Construction

[0030] With reference to the foregoing drawings, various examples will now be disclosed, which illustrate, by way of illustration only, various embodiments of the invention contemplated herein.

[0031] Figure 1A to Figure 6B A filtration unit 100 according to an embodiment of the present invention is provided. as in figure 2 As best seen in , filter unit 100 generally consists of a housing 110 mounted to a ventilation system (not shown), a replaceable media cartridge 120 containing filter media (not shown), and a first cover 130 .

[0032] go to image 3 , unfiltered air enters the filter unit 100 at a plurality of perforations 102 in the housing 110 . Unfiltered air is drawn into media cartridge 120 where it passes through filter media (not shown). The filtered air then enters central air passage 106 and exits at outlet 108 . Cover 130 prevents unfiltered air from entering central air passage 106 directly and ensures filtered air exits at outlet 108 . As discussed fu...

Abstract

An air filtration unit is provided with a replaceable media cartridge to reduce the time, material, and labour costs required to maintain the filtration system. A housing portion includes a mounting flange, a supporting frame, and a collar for receiving a replaceable media cartridge. The replaceable media cartridge slides into the frame. At least one cap ensures that air flows through the cartridge and may provide a handle for easy removal and replacement of the cartridge.

Description

technical field [0001] The invention relates to the field of air filter units. More specifically, the present invention relates to air filtration units having replaceable media cartridges. Background technique [0002] Air filtration units are used in everything from small appliances to cars to heating and air conditioning systems. Typically, air filtration units draw air through filter media in order to remove contaminants from the airstream. [0003] In hydroponic and greenhouse facilities, air filters are used to reduce odors and control emissions from growing operations. Ambient air circulates through the activated carbon in the filter before returning to the greenhouse or being vented to the environment. [0004] In a greenhouse or hydroponic environment, air is usually drawn into the air filtration unit through a "pre-filter" supported by an external wire mesh. Incoming air passes through a layer of activated carbon and enters a central chamber where purified air i...
