AC Infinity Inline Filter Box with 8" MERV 13 Filter, Whole House HVAC Filter Kit, Fits 8" Inline Duct Fans for Fresh Air Intake and Ventilation

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!!!

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

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.

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.

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.
