## Description

AC Infinity Inline Filter Box 6" with High Efficacy Filter, Whole House HVAC Filtration Kit, Fits 6-Inch Inline Duct Fans for Fresh Air Intake and Ventilation - desertcart.com

Review: Great box, worth the money! - Great filter box. Built with good materials. Hinges are smooth and the latch is solid and looks and works great. I used this for my fresh air intake with a motorized damper for my A/C system. The inlet and outlet flanges were true to size and the door sealed very well with no leakage. It was easy to install and remove the included filter. This is heavy gauge metal and makes the box have some weight to it, so be prepared to have a way to mount or hang it. It's easy to tell this is a good product. The shipping box and packing were really nice....I hated to throw it away. You get quality with this box, it's worth the money, which is hard to find these days.
Review: I found a replacement filter for the 6" model - We used this 6" model for a fresh make up air for our house. Reading the review we realized people were upset that AC Infinity doesn't sell replacement air filters and those readily available filters at the big box store won't fit. If you are searching for a replacement then buy the Nordic Pure 12x20x1. desertcart sells this brand of filter as well. The actual measurements for this filter is: 11.5 x 19.5 x 0.75 inches. Although this air filter is about 0.25-.05 in short on the length and width, it still fit the air box and the seal is still in tact. See pictures for a visual illustration and reference my finger. As for the air box itself, this is a well constructed and high quality air inbox. This is expensive but I believe the quality and craftsmanship justified the price. I hope this review helps.

### ⭐⭐⭐⭐⭐ Awesome build quality on this beauty!
*by J***T on March 24, 2024*

This box looks so good, it's almost a shame I have to mount it in a hidden area. It's solid. It's tough, and the finish is great. The box it was packaged in got heavily damaged in shipping, and the strength of the air handler itself is what saved it from damage. Only a few nicks to the powdercoat finish, no discernible dents, and no affect to the body or door. It latches solidly, seals competently, and comes with a pleated filter already included inside it (independently shrink-wrapped, of course) I also bought a pair of backdraft butterfly dampers (6" as well) from AC Infinity, and their build quality blew me away just as much. I'm really impressed with this company. Yeah, their stuff isn't the cheapest, but you really get what you pay for with these people. I'll be trying to use their products in future projects as often as possible. Highly recommended!!
