Review: High quality, filters air. - 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!!!
Review: Sturdy - 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

### ⭐⭐⭐⭐⭐ Good product. Well built
*by T***M on October 25, 2023*

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.
