  • 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.

    Spray stops working
    Size: 5 Ounce (Pack of 2)
    I’ve been buying this product for awhile and keep experiencing issues. It protects your skin well but is sometimes hard to spray and half the time the nozzle stops working while there is still product in the bottle.

    Goes on clear, superior protection and moisture to skin
    Size: 3 Fl Oz (Pack of 2)
    Love this moisturizing formula, beachy scent and really protective. I used in South Pacific and needed a reliable sunscreen to last and stay protective while in water. This one delivers and size is TSA compliant.

    Terrific Quality
    Size: 3 Fl Oz (Pack of 2)
    Best suntan lotion. I’ve used this brand for a couple of years now and am impressed at how well it works. I have fair skin and it truly helps so I don't get burned like I used to with other brands.
