Why Buy From Grow Tents Depot
  • Duct Filter Box: This is designed for use with inline fans to circulate fresh air and block dust and odors. It is built with 1mm thick cold-rolled steel and aluminum duct flanges, which allow it to withstand extreme weather. A slide lock door enables easy access to the inner chamber, while a soft neoprene layer creates a dust-free seal.
  • High Efficacy Filter: Included is a standard filter that effectively traps particles like dust, dirt, lint, and odor. The air filter box measures 23.46 x 8.42 x 11.73 inches, fits 6-inch inline fans, accommodates 12 x 20 x 1-inch filters, and provides a maximum circulation of 800 cubic feet per minute.
  • Product Description: This is a whole-house air filtration system designed for use with inline duct fans such as the Cloudline Series. It blocks particles like dust and dirt from entering your home in intake applications. The box is built using 1mm thick cold-rolled steel with a matte black powder coating. This combines with aluminum duct flanges to create a sturdy, weather-resistant structure. It features a slide lock for easy access to the inner chamber, with a soft neoprene layer for dust-proof sealing.
  • Applications: The air filter box accepts standard MERV filter replacements that slide into the inner chamber's filter slot. It comes with a high-efficacy pleated air filter, capable of trapping 0.3-1.0 micron-sized particles such as dust, dirt, lint, and odor. The duct flanges fit with matching sized 6-inch inline fans, enabling streamlined installation. Attaching the air filter box at the start of your ductwork will dramatically reduce airborne particles in your home. Use with a high static pressure fan, such as the Cloudline Series of duct fans, is highly recommended for maximum filtration.

    This Filter Box Is Fantastic

    I have been searching quite some time for a way to filter my the incoming air to my grow tent. The nylon stocking bit I was using was not getting the job done. Then I found AC Infinities Air Filter Box! It is exactly what I was looking for! This thing is great! I have already purchased 3 of them so far and plan to purchase 1 more.
    Thank you AC Infinit

    Very well built does the job

    I use on my 5x5 tent intake and so far it works great. It looks good and is easy to change the filter. I would say only complaint is it should come with a way or kit to mount to a wall or surface. I am planning on buying more..

    Well built

    This filter box is well built just like all ac infinity products I've purchased except it doesn't have any way to mount it.
