## Customer Reviews

### ⭐⭐⭐⭐⭐ Great inline air intake filter
*by R***N on November 9, 2023*

After installing an ERV, I noticed the intake air is not sufficiently filtered and that caused PM 2.5 particle counts to go up in the house. This filter is a great solution and I placed it before the ERV to filter the intake air before it reaches the ERV. This has dramatically reduced PM 2.5 particle count back to normal range.It's easy to install and is very solid. It doesn't come with any means to mount the filter or hang it. It's also not insulated so it can condensate if outside air is much colder than inside. I was worried about the box but it was well packaged. Finding the right filter for the 4 in and 6 in version might be a problem, but I think the Home Depot HDX 12X20 MERV 13 filter should fit based on the size of the filter online. But I am using the provided filter at the moment.

### ⭐⭐⭐⭐⭐ I found a replacement filter for the 6" model
*by N***M on December 30, 2022*

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. Amazon 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!!
