The iPower 4 Inch 154 CFM Inline Ventilation Fan with Variable Speed Controller and 4” Air Carbon Filter 8 Feet Ducting, Kits, Combo Set for Grow Tent is one of the most powerful and flexible ventilation fans we tested. It comes with 4-inch-diameter ducting, and when fully extended, the tubing is 8 feet long, so you can run the fan pipe very far from your grow tent. The fan is quiet, and it feels sturdy and well-made. The variable speed controller lets you dial in the ideal airflow for your grow tent, and it comes with two metal clamps that attach the fan to ducting. The variable speed controller is handy for tailoring the fan's air output to fit a particular growing environment. The fan's carbon filter has 50mm of activated carbon and is 4 inches in diameter. The filter's efficiency ratings are 0.01 microns for pollen, 0.005 microns for smoke, and 0.002 microns for odor and dust. The filter's 8-foot length is long enough to reach most of an 8-foot grow tent, and its 4-inch diameter is small enough to fit through most grow tent doors.

The VIVOSUN 6 Inch 390 CFM Inline Fan with Speed Controller, 6 Inch Carbon Filter and 8 Feet of Ducting, Temperature Humidity Monitor for Grow Tent Ventilation is an affordable and effective fan for growing plants in indoor grow tents and hydroponics grow rooms. The fan's 6-inch carbon filter effectively eliminates pungent smelliness from indoor grow tents, and it is easy to clean and reuse. The fan's 390 CFM output removes air from grow tents quickly, but it's quieter than fans with higher CFM ratings. The fan's built-in temperature and humidity monitor allows you to control the temperature and humidity in your grow room, so your plants grow faster, healthier, and bigger. The fan's powerful motor runs quietly, and its sturdy, flexible steel wire supports heavy-duty triple layer duct walls. The fan's built-in 3-foot power cord allows it to be mounted nearly anywhere. The fan's LED power indicator light glows red when it's running, and turns green when it's ready.

The VIVOHOME 4 Inch 188 CFM Inline Duct Fan with 4 Inch Carbon Filter Control and Australia Virgin Charcoal Combo Set (model number: 4 Inch 188 CFM Duct Fan with Carbon Filter) is a high-quality, versatile, and affordable fan that performs well both as a ventilation system and as a air purifier. This fan is quiet enough to use in a bedroom, and it moves a significant amount of air, so it's ideal for use in a grow room or a room with a lot of furniture and people. The fan is also easy to install, and it comes with all the necessary ventilation hoses, so it's simple to connect it from your ductwork to your fan. The carbon filter removes odor and any smoke or soot particles that may be present in the room, and its large size ensures it will last for years. The fan can circulate air quickly, so it's a good choice for rooms where you need a strong flow of air, such as a bathroom or a kitchen. The VIVOHOME 4 Inch 188 CFM Inline Duct Fan with 4 Inch Carbon Filter Control and Australia Virgin Charcoal Combo Set is quiet, easy to install, and well-made, and it's a good choice for both ventilation and air purifiers.

The VIVOSUN 6 Inch 390 CFM Inline Duct Fan with 6 Inch Carbon Filter is a surprisingly powerful fan for its compact size. The unit is relatively quiet at 43 decibels, yet it moved enough air to keep a 6-foot by 6-foot grow room at a comfortable 70 degrees. This fan is handy for dust control in homes or grow tents, where it's not possible to open windows or doors. The carbon filter helps remove not only odor, but also particulates and bad odor. One drawback: The carbon filter is sold separately, so you'll have to buy a replacement filter after about 6 months. The unit is well-made and easy to assemble, and it comes with a one-year warranty.

The AC Infinity Air Carbon Filter for Inline Duct Fan is clean and quiet, and it achieves similar results to the Air King CC1, our former top inline fan filter, which is more expensive and much larger. The carbon is of good quality, and the thick fabric pre-filter does a great job of trapping dust and dirt. The filter is easy to install, and it comes with enough fabric pre-filters to last for hundreds of filtered air intakes. The AC Infinity Air Carbon Filter is also the only inline fan filter we tested that comes with a grounding strap, which its manufacturer says protects the fan against electrical failure. The AC Infinity Air Carbon Filter is easy to install, quiet, and does a good job of filtering odors and chemicals out of grow rooms. However, it blows a lot of air through a single intake, so it may not be suitable for discreet grow rooms.

The 6-inch 440CFM VIVOHOME Inline Duct Fan with Air Carbon Filter Control Scrubber and 8 Feet Aluminum Flexible Dryer Vent Hose for HVAC Ventilation Set of 3 is a solid choice for people who need an inline fan for ventilation in tight spaces. The carbon filter in particular is effective at neutralizing odors and getting rid of cigarette smoke. However, we weren't able to test its filtration performance for other types of odors. The fan is also quiet, and the aluminum hose feels sturdy, but it's a bit on the heavy side. The fan and the carbon filter are easy to install, and the fan comes with a plastic cover that helps keep dust and dirt out of the fan. The fan can run on either AC power or 9-volt batteries, and it comes with a speed controller that lets you adjust the fan's speed. The fan's mounting bracket is small, so it doesn't look out of place in most rooms.

The Dyson Pure Cool is a portable air purifier that is compatible with both Dyson Pure Hot + Cool and Pure Cool air purifiers. It features a 360-degree filter that captures 99.97% of dust and allergens as small as 0.3 microns, and includes a HEPA filter and activated carbon filter. The Pure Cool purifier is quiet, and it has a thermal towelette that removes excess heat from the air purifier, which helps it run more efficiently. The purifier is easy to set up, and it comes with detailed instructions. The Dyson Pure Cool sells for $150, which is a little higher than other purifiers, but the Dyson brand is well-known, and it provides better air quality.

The iPower 4-inch inline fan is an efficient, quiet, and affordable way to circulate air in your grow tent. While newer models feature built-in speed controls, this older model has a manual speed controller. It also lacks an automatic humidity sensor, which newer models include. But unless you find yourself constantly monitoring the humidity level in your tent, that shouldn't be a deal-breaker. The fan is also quick and quiet, and it also comes with an attractive set of black ducting clips and a flexible ratchet hanger. The fan's high air volume and 195-cubic-foot per minute air volume are more than enough for typical grow tents. The fan works equally well for air ventilation in indoor grow tents and for air ventilation in outdoor grow tents. The fan's carbon filter also helps reduce odors, but in our tests, it blocked more odors than some other filters. The fan's best feature, however, is its price: this fan costs just a few dollars more than our pick, the Vidar 4-inch inline fan, but it offers more power and much quieter operation.

When it comes to grow room ventilation, fans are among the most important tools you can have. Grow room fans circulate air and remove heat from plants, which in turn allows them to grow. A grow room blower is an important tool for a grow room, and a good one will keep your plants happy and healthy. iPower's GLFANXINLLITE4FILT4MRCTR is a good buy. It's a small, quiet fan (it runs at 30 to 45 decibels), and it has a 4-inch diameter. It has powerful output and is Very quite. The fan is compact, so it's easy to install, and it comes with several feet of flexible ducting, so it's easy to route the exhaust of your grow room blower to where you want it. The fan has 6-speed control, and the low- and high settings allow you to fine-tune the airflow and noise to your specific grow. The fan's power switch is recessed, so it's easy to accidentally turn the fan off. It also doesn't have an auto-off feature, so it doesn't shut off when the power switch is turned off. The fan's pre-filter should be replaced 6 months or 1,000 hours of use, which, depending on your grow, may be more or less frequent, but it prevents carbon dust from clogging the fan and damaging it. The fan's power cord is 6 feet long, which is long enough to run the fan to a convenient location in your grow room. iPower warranties the fan for 1 year.
