  • Kit Contents
  • 1+ refill to match the filtration capacity of two standard 4" carbon filters while costing less.
  • Larger chamber is lab-tested to block odors as effectively as standard filters with no compression required.
  • Dual-layered steel mesh with protective coating withstands high humidity in grow tents through many grow cycles.
  • Product Description: A wholly original replenishable carbon filter designed to permanently replace standard duct filters. This iF Award-winning patented structure can be regularly refilled to offer a cost-effective and sustainable solution for unwanted odors in your grow tent. The charcoal fan filter kit also includes 1+ refill, making it as efficient as two standard inline carbon filters while proving more affordable. You can purchase additional refills at a fraction of the price of an entirely new carbon scrubber to further increase the value of this kit. Features an expanded chamber that enables you to achieve factory carbon compression and the same lab-tested levels of odor-blocking effectiveness as standard carbon filters. This also eliminates the need for you to actively compress your replacement charcoal and facilitates the refilling process.
  • Eco-Friendly Design: This first-of-its-kind filtration system removes the need to routinely purchase replacement filters and dispose of the old units. Each carbon filter features premium-grade Australian virgin charcoal and comes with 1+ refill. Its activated charcoal utilizes an enhanced surface area with a higher adsorption rate to help extend the time between refills. Further lengthen the charcoal bedding's lifespan by reversing the filter's easy-to-remove flanges. You can compost the used supply when replacing the charcoal to maximize its utility even further.
  • Highly Durable Build: The activated charcoal is safely locked within your odor filter by aluminum flanges and a secure rubber seal. The filter itself employs two layers of galvanized steel meshing with a sandblasted finish to protect the charcoal bedding. These multiple layers work together to effectively block odors in even the most humid environments by ensuring increased resistance to rust and corrosion.
  • Applications: This refillable carbon filter pairs with 4" inline duct fans and ducting to improve air quality in hydroponic grow rooms and grow tents. The kit includes a convenient funnel and scoop set and one charcoal refill for continuous odor scrubbing. Additional refills are available for purchase.

    From Puppy Teething to Adult Favorite – 7 Years Later
    Color: Teething Stick, Color: Teething Stick
    This has been one of the best toys I’ve ever bought! My dog has loved the Pupstages Cool Teething Stick since she was a tiny puppy, and now at 7 years old, it’s still one of her absolute favorites. It’s been amazing for soothing teething when she was little, and now she still enjoys chewing on it and carrying it around. It’s held up surprisingly well over the years, especially considering how much use it’s gotten. I also love that you can cool it for extra relief—it really helped during those puppy stages. If you’re looking for a toy that lasts and actually becomes a long-term favorite, this is definitely it. Highly recommend for both puppies and even older dogs who still love a good chew! 🐶

    My puppy loves it
    Color: Teething Stick
    It's cute and a good size for my chihuahua puppy. It seems to be slightly tearing at the seam in the middle, but hopefully it will hold up.

    LOVE this tough toy! My teething puppy is still enjoying it!
    Color: Hedgehog
    LOVE the hedgehog! Very tough! My dachshund has not been able to chew off any of the 'nubs', and does she try! lol The only thing is, the first thing she did was chew off the nose, but I discarded it and watched her closely to make sure she didn't chew off any more, and no, its still being chewed on. Wish I could find more toys like this one!!
