AC Infinity Inline Filter Box 150mm with High Efficacy Filter, Whole House HVAC Filtration Kit, Fits 150mm Inline Duct Fans for Fresh Air Intake and Ventilation, 6-Inch

Ajouté a ma ligne d'echangeur d'aire avec un filtre HEPA. Tres satisfait beaucoup moins de problemes de toux dans la famille. Tres simple et plusieurs types de filtres pour cette dimension.

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.

well made and it works perfectly

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.

Great product. It allows me to move all my ventilation outside the tent, I use it as my pre filter and have the fan mounted directly to the carbon filter, giving far more room inside.
