  • 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.

    Reliable protection that stays put during workouts!
    Style: SPF 50, Size: 8 Fl Oz (Pack of 1)
    I’ve tried many expensive name-brand sunscreens, but this Amazon Basics version performs just as well, if not better. It’s become my go-to for morning runs and trips to the beach because it actually stays on even when I’m sweating. Why I gave it 5 stars: Non-Greasy Formula: Unlike other sport sunscreens, this one absorbs quickly and doesn't leave that heavy, sticky film on my skin. Actually Water Resistant: I’ve used it for laps in the pool and long hikes; as long as I reapply as directed, I haven't had a single sunburn. No "Sting": One of the best things is that it doesn't run into my eyes and sting when I start to sweat—a huge plus for runners. Great Value: You get a generous 8-ounce bottle for a fraction of the price of "premium" brands. The fact that it’s formulated without Oxybenzone is an added bonus for peace of mind. If you’re looking for effective, no-frills sun protection for an active lifestyle, you can't beat this. It’s a staple in my gym bag now!

    Great value and very practical
    Style: SPF 50, Size: 8 Fl Oz (Pack of 6)
    This sunscreen is a great value for the price. The SPF 50 protection works well and the lotion applies smoothly without feeling too greasy. It absorbs nicely and provides good coverage for outdoor activities. I especially like using these bottles to refill the sunscreen dispensers at my Airbnb for guests. It’s convenient, reliable, and affordable when you need multiple bottles available. Overall, it’s a solid everyday sunscreen and a very practical option if you need good protection at a reasonable price.

    good price for good product. applies well, shake and store upright
    Style: SPF 50, Size: 8 Fl Oz (Pack of 1), Style: SPF 50, Size: 8 Fl Oz (Pack of 1)
    I believe it is equal to the name brands It is 50 SPF Sun Protection Factor so it offers strong UV A and UV B protection which are the 2 ranges of sun rays that do the skin damage and burning. It is an easily absorbed lotion that when rubbed goes into the skin and is not visible. It is thick and goes on with a non shiny, non greasy, solid thick feeling which is what we need for it to stay on as long as possible. It feels good after being rubbed in in that it feels dry and not overly greasy or with no shine and sheen. It is a good product and offers burn protection to me in some clear-sky strong sun uses. Reapply after entering the pool water or swimming laps and after an hour (all sunscreen labels say reapply after 80 minutes which I believe is per recommendations of the federal FDA or some medical studies). I reapply often and I still get tanned but I do not want to burn.

    Survived the sun like a pasty legend
    Style: SPF 50, Size: 8 Fl Oz (Pack of 1)
    I bought this sunscreen because I’m basically a human marshmallow — one hour in the sun and I’m toasted. This Amazon Basics Sport SPF 50? It’s like armor for the pale and easily crisped. I slathered it on before a full day of hiking, sweating, and pretending I enjoy direct sunlight, and guess what? No burn. Not even a pink glow. Just victory. It goes on smooth, doesn’t feel greasy, and somehow stayed put through sweat, water, and my dog licking my arm. It’s fragrance-free, which means I didn’t smell like a coconut smoothie or a chemical spill — just clean and protected. Pros: • High SPF that actually works • Sweat and water resistant — like, impressively so • No greasy residue or weird smell • Affordable and comes in a big ol’ bottle • Didn’t turn me into a lobster (the bar is low, but still) Minor feedback: It’s not fancy or trendy, but honestly, I’m here to not burn — not win a skincare award. Also, it takes a bit of rubbing in, but once it’s on, it’s locked and loaded. Final thoughts: If you want solid sun protection without the drama, this stuff delivers. Whether you’re hiking, swimming, or just trying to survive summer, it’s a reliable sidekick. Would absolutely buy again — my skin demands it.

    Great Sunscreen at a Great Price!
    Style: SPF 50, Size: 8 Fl Oz (Pack of 1)
    Love this sunscreen. I live in FL and like to walk most mornings, and need a good sunblock. This Amazon Basics is far better than my previous, far more expensive brand. It's a great price for great quality. I've been using it on my body & face, it's non-greasy, absorbs well, and really seems to offer very good sun protection. And I really appreciate the next day shipping on my past two orders, Amazon. Thanks for the great product & great service!
