Review: good quality - great product; works well
Review: Works great so far - I've only been testing this fan/filter for a few weeks, but so far I'm very happy. It moves a ton of air in my 4x4 and the fan (which I installed inside the tent) is decently quiet when cranked up to max settings. It was very easy to assemble and install, and I have no experience with these kinds of things. I did opt to seal the ducting with aluminum foil tape in addition to the hose clamps -- the tape needs to be bought separately. That said, I don't know if that's even necessary. The smart monitor is REALLY nifty. Tons of settings to automatically adjust for different scenarios when certain conditions are met. When I thought I had a problem with the monitor (it was actually just me being dumb though) customer support responded to my question in a few hours. Really can't complain! I'll try to update a year or so down the road and let you know how well it ages. In the meantime though, I'm a happy camper..

## Features

- 𝐒𝐦𝐚𝐫𝐭 𝐀𝐩𝐩 𝐂𝐨𝐧𝐭𝐫𝐨𝐥：Connect to the MARS HYDRO App to control the fan anytime and anywhere. It includes a temperature and humidity sensor for real-time climate monitoring and automated regulation. The iControl Controller is powered via its RJ12 port and requires no external power supply.
- 𝐅𝐮𝐥𝐥𝐲 𝐀𝐮𝐭𝐨𝐦𝐚𝐭𝐢𝐜 𝐀𝐝𝐣𝐮𝐬𝐭𝐦𝐞𝐧𝐭：Program the fan to monitor climate changes in real time; it will automatically adjust the fan’s on/off status, speed, and airflow according to your preset settings, freeing you from manual operation.
- 𝐏𝐨𝐰𝐞𝐫𝐟𝐮𝐥 𝐈𝐧𝐥𝐢𝐧𝐞 𝐅𝐚𝐧：The MARS HYDRO inline duct fan features a durable plastic housing, and its fan blades adopt a mixed-flow design to deliver active, consistent airflow to your growing space. Operating at 2600 RPM, the fan provides a powerful 205 CFM of airflow to meet your ventilation needs.
- 𝐒𝐮𝐩𝐞𝐫𝐢𝐨𝐫 𝐀𝐜𝐭𝐢𝐯𝐚𝐭𝐞𝐝 𝐂𝐚𝐫𝐛𝐨𝐧 𝐅𝐢𝐥𝐭𝐞𝐫：Crafted from imported 1050+ Virgin Australian activated charcoal, the carbon filter delivers 100% filtered airflow. It offers enhanced absorption capacity to efficiently remove odors, and it comes with a machine-washable pre-filter cloth to prevent carbon residue buildup
- 𝐂𝐨𝐦𝐩𝐥𝐞𝐭𝐞 𝐕𝐞𝐧𝐭𝐢𝐥𝐚𝐭𝐢𝐨𝐧 𝐒𝐲𝐬𝐭𝐞𝐦：This all-in-one kit includes everything you need: a 4” Inline Duct Fan, a 4” Carbon Filter, an iControl Controller, a 25ft Flexible Duct, 3 Stainless Steel Clamps, and 2 Grow Tent Vent Covers. No additional parts are required—unbox and use directly.

### ⭐⭐⭐⭐⭐ Powerful fan with automation, serenity.
*by J***S on May 6, 2021*

This is quite possibly the best in line fan ever. Not only does it completely sustain a 3x3 tent, it literally sucks the humidity out of the whole room as well. The fact that it has a temperature and humidity sensor just sends it over the top. The mountable controller makes changing settings a breeze. The automation is a must have, I do not know how was running a fan full blast 24/7 before. Probably because there was no solution like this out there. Mars Hydro has really outdone themselves this time. Top of the line fan with a great controller. I will be ordering more for my other grow area. I can honestly say that Mars Hydro products are some of the best in the game right now. They have come a long way and continue to impress me.
