AC Infinity 8-Inch Inline Filter Box with High Efficacy Filter

Overall I’m really pleased with this filter box. I’m building a post and beam house and there’s no room anywhere for an air handler system. This compact fan and filter box setup fits nicely under the stairs and can move a lot of air. The filter box is sturdy and the filters fit nicely. Small detail, but the latch has a very satisfying and sturdy click. It’s the little things.

Simple but high quality. Wasn't able to find anything comparable and is working great for my application.

Sturdy! I got this after an outside air intake was installed and a large amount of box elder bugs made it into the HVAC system, keeping them toasty inside all winter until they came out the ducts. The company installed a screen that did absolutely nothing. So after digging around to find a solution and found this. Mounted it right after the outside vent, and also put a finer screen on the outside grill as well. Not the bugs and pollen stays out of my ducts and I’m much happier

I think it's overpriced given it's just a metal box, but there weren't any alternatives. I wish it was insulated and that it would accept wide air filters. It was easy to install and use.

Like everything AC Infinity makes, it’s extremely high quality. It’s pricey, but I haven’t found something like this on the market. It allows me to filter the air on my air intake. For the exhaust I use a carbon filter and would not use this. It was very easy to instal. The filter size was easy to order replacements for. Highly recommend!!!

Hooked up to an AC Infinity fan/blower, I pull air from the outside into sub-basement area to improve ventilation and reduce wind-blown dust through the normal multiple of regular air vents in the foundation walls - by creating positive pressure. The unit is quite sturdy, comes with a pretty basic air filter. Two improvement areas: the seal between the filter and the air box is imperfect and allows dust and small bugs to get pulled into and through the unit without touching the filter; and the button to open the lid on the box to check or change the filter is awkward to use with one hand. Overall satisfied with the filtration kit, which I easily improved by hanging out the disposable filter for a better 3M HEPA filter,, and by judiciously applying duct tape in a couple of key interior (to the box) areas to prevent unfiltered air from entering the home.

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.

Used it for a fresh air intake for make up air on a 800 cfm range hood. Just didn’t want to suck on dust from outside. There is a separate exhaust for range hood that’s not in this picture. This is the 8” that requires a 14”x20” filter. Will purchase more of these in future as I need.

Pretty impressed with the hole AC infinity range. All the items I’ve ordered have been very good quality, easy to install and app connected to maximise usability. Would recommend.

Decent product, easy to service filter, but did not come with a HEPA element. Just a regular screen, so don't be fooled by the ad.
