iPower 4 inch 8 feet Non-Insulated Flex Air Aluminum Foil Ducting Dryer Vent Hose for HVAC Ventilation with 2 Clamps, 4'' X 8' New, Silver

I just checked on this with Amazon, as I've had it for over a year now and am in middle of my third grow through it. It's huge and heavy, but it works. I've washed the outer cloth pre-filter jacket between grows and it really stops a lot of dusty dirt. It significantly reduced odors. I have not replaced the activated charcoal yet. We'll see how it does with this latest batch once flowering begins. I paid about half the price of the vivo and others currently available. If you can get this brand in a smaller diameter, do it!.

I'm a stealth micro grower using a Superlocker. As I get better at my craft, my need for odor control increases. The filter that came with the Superlocker was a joke and I immediately recognized the need for an upgrade. I purchased the prior version of this filter in January 2019 and it completely removed the odor emanating from my grow and it reduced the fan noise a bit as well. With the reversible cowling, I was able to get over two years out of it. I was thinking of buying a Can filter but way pay more for the same performance?

Did great for what I needed it for.

I couldn’t be more pleased with the iPower 6-inch 8-feet Flexible Aluminum Ducting! This ducting is a game-changer for anyone in need of reliable ventilation, whether it's for HVAC systems, grow tents, kitchen exhausts, or bathroom ventilation. The 4-layer construction (PVC layer + aluminum foil + PET + aluminum foil) is incredibly durable and provides excellent protection from tears, punctures, and leaks. The build quality is outstanding—the aluminum foil combined with the PET material makes this ducting both heat-resistant and corrosion-resistant, able to withstand a wide range of temperatures from -18°C to 85°C (-22°F to 185°F). I’ve used it in different applications, and the ducting has performed flawlessly in every situation. Whether it’s circulating air in my grow room, venting moisture and odors from the bathroom, or exhausting heat from my kitchen—this ducting does it all with ease. One of the standout features is the fireproof coating and the reinforced steel wire helix that provides extra strength and durability. This ducting isn’t just flexible; it’s tough and will not unravel even when cut to shorter lengths. The flexibility also makes installation super easy. It bends and adapts to whatever space you need to run it through, whether it’s tight corners or confined areas like attics, crawl spaces, or grow rooms. You won’t have trouble maneuvering it into place. I love how easy it is to install. It comes with a pair of stainless steel clamps that make securing the ducting to your system a snap. These clamps are strong and hold the ducting in place, preventing any accidental disconnections or leaks. The ducting itself is also easy to cut using standard metal snips or wire cutters if you need a custom length. Another benefit is the airtight seal provided by the internally crimped galvanized steel strip, which ensures there are no leaks—critical for maintaining efficient airflow in a variety of applications. The ducting also works wonderfully as an intake and exhaust duct for active-cooled light fixtures, air intake/exhaust in grow tents, and even as a dryer vent. I’ve used it in multiple scenarios, and I’ve been impressed by its ability to maintain consistent airflow while reducing temperature fluctuations in my growing environment. The versatility of this ducting is unmatched. From greenhouses and grow rooms to kitchens and bathrooms, it’s suitable for all kinds of ventilation systems. Plus, when not in use, the ducting is compact and takes up minimal storage space—perfect for when you don’t need it constantly deployed. Overall, I can’t recommend this iPower Flexible Aluminum Ducting enough. It’s well-made, reliable, and extremely versatile. Whether you need to handle high-temperature exhaust, air circulation, or moisture control, this ducting performs exceptionally well in every situation. It’s a solid investment for anyone looking to improve their ventilation system. Highly recommended!

Had an air filter that burned out. Put an inline fan on it but needed the fan run rum slowe and the speed control works perfect. Was a good price as well.
