  • Product Description: A whole-house air filtration system designed for use with inline duct fans such as the CLOUDLINE Series, to circulate fresh air by blocking particles like dust and dirt from entering your home in intake applications. Each air filter box is built using 1mm thick cold-rolled steel and finished with matte black powder coating. This outer body build comes together with aluminum duct flanges to create a sturdy build capable of withstanding inclement weather. Its low-maintenance design features a hinge-sealed door equipped with a slide lock that provides easy access to the inner chamber. The door is lined with a soft neoprene layer that keeps the filter in place, and dust from seeping inside.
  • Applications: Each air filter box accepts standard MERV filter replacements that slide into the inner chamber's filter slot. Comes included with a high-efficacy pleated air filter, capable of trapping 0.3-1.0 micron-sized particles such as:
  • Dust
  • Odor
  • The duct flanges fit with matching sized 4" inline fans and enable a streamlined installation to create high efficiency filtration in HVAC and grow applications. Attaching the air filter box in the starting end of your ductwork will dramatically reduce suspending particles in the air inside your home. Use with a high static pressure fan like the CLOUDLINE Series of duct fans is highly recommended to ensure maximum filtration.

    Overall, I liked the outfit and would defiantly order another one, just getting a bigger size shirt.
    Size: 3X-Large, Color: Light Blue
    I love the outfit, the shirt, which was a 3X was just a little to small. But the pants fit great. The outfit was very comfortable and light weight.

    All of my shirts, including the green one in the picture, are 3X and they fit great, some are loose. If this linen shirt from Coofandy is a 3X, I’m Mickey Mouse.
