Why Buy From Grow Tents Depot
  • Reusable Carbon Filter: This patented design eliminates the need for replacing entire filters. The package includes over one refill, matching the filtration capacity of two standard 4" carbon filters, thereby offering a cost-effective solution. The removable twist-off flanges allow for easy, tool-free refilling using the included funnel and scoop.
  • Efficient Odor Blocking Capability: The expanded chamber is lab-tested to block odors as effectively as standard filters, without needing any compression. The dual-layered steel mesh with a protective coating is designed to withstand high humidity in projects through multiple cycles.
  • Product Description: This unique carbon filter design is intended to permanently replace standard duct filters. Its patented structure can be frequently refilled, offering a cost-effective and sustainable alternative for eliminating unwanted odors in your project. This kit includes over one refill, making it as efficient as two standard inline carbon filters while being more affordable.
  • Eco-friendly Design: This novel filtration system eliminates the requirement for regular purchase and disposal of replacement filters. Each carbon filter features premium-grade Australian virgin charcoal and comes with 1+ refill. The activated charcoal boasts an enhanced surface area with a higher adsorption rate, which effectively extends the duration between refills. The easy-to-remove flanges can be reversed to prolong the life of the charcoal bedding, which can be composted when replacing the charcoal to optimize usage.
  • Highly Durable Build: The activated charcoal is safely contained within the odor filter by aluminum flanges and a secure rubber seal. The filter features a dual-layer galvanized steel mesh with a sandblasted finish to protect the charcoal bedding. The combined layers effectively block odors in even the most humid environments by offering increased resistance to rust and corrosion.
  • Applications: The refillable carbon filter is compatible with 4" inline duct fans and ducting, perfect for improving the air quality in hydroponic projects. The kit includes a convenient funnel and scoop set and one charcoal refill for continuous odor scrubbing. Additional refills are available for purchase.
