The quality and craftsmanship is excellent, I bought an 8” duct box, comes with one filter
D. Hoover –
Solid filter box. No one else seems to really sell something like this already made. The only problem was that the seams aren’t actually sealed. The metal fits pretty tight, but if I shine a light I can see it a bit. I used just some mastic to make sure it all stays sealed.

I installed this in my very tight house to resolve a problem with my gas water heater venting. This solved that problem by adding more air that exhausting.

This has been a game-changer in improving the air quality around my L7 miner setup. As a cryptocurrency miner, heat dissipation and proper ventilation are crucial, and this filtration kit has exceeded my expectations. The installation was a breeze, seamlessly fitting with my 8-inch inline duct fan for optimal airflow. The high efficacy filter has proven to be incredibly effective in capturing dust and other airborne particles, ensuring that my L7 miner operates in a cleaner environment. I’ve noticed a significant reduction in dust buildup on the miner and surrounding surfaces, which translates to better heat dissipation and improved performance. The durability of this filter box is commendable, and its quiet operation is a bonus. If you’re a miner looking to enhance your air filtration system, I highly recommend the AC Infinity Inline Filter Box 8″ for the L7 miner or any other mining rig. It’s a worthwhile investment that positively impacts both the performance of your equipment and the air quality in your mining space.

I bought this to feed my hybrid electric water heater. It is a regular size filter you can get anywhere. I now use the air comming out of the water heater to cool my house with highly filtered air
