Its slide lock door and neoprene seal enable easy, dust-free filter changes, making it an essential upgrade for professional-grade ventilation and air quality. ## Description Product Description A whole-house air filtration system designed for use with inline duct fans such as the CLOUDLINE Series, to circulate fresh air by blocking particles like dust and dirt from entering your home in intake applications. Each air filter box is built using 1mm thick cold-rolled steel and finished with matte black powder coating. This outer body build comes together with aluminum duct flanges to create a sturdy build capable of withstanding inclement weather. Its low-maintenance design features a hinge-sealed door equipped with a slide lock that provides easy access to the inner chamber. The door is lined with a soft neoprene layer that keeps the filter in place and dust from seeping inside. Applications Each air filter box accepts standard MERV filter replacements that slide into the inner chamber’s filter slot. Comes included with a high-efficacy pleated air filter, capable of trapping 0.3-1.0 micron-sized particles such as Dust Dirt Lint Odor The duct flanges fit with matching-sized inline fans and enable a streamlined installation to create high-efficiency filtration in HVAC and grow applications. Attaching the air filter box to the starting end of your ductwork will dramatically reduce suspending particles in the air inside your home. Use with a high static pressure fan like the CLOUDLINE Series of duct fans is highly recommended to ensure maximum filtration. HVAC Filter Box Intake air filtration system designed to circulate fresh air and block particles from entering indoor settings. Home Inline Air Filtration When used with a high static pressure duct fan, filter boxes can not only purify the air with maximum efficiency but also provide light cooling to improve comfort. Place this filter box at the beginning of your ductwork to keep dust, dirt, lint, and odors out, reducing suspending particles inside your home. Sturdy and Weather-Resistant Made of 1mm thick cold-rolled steel and aluminum duct flanges with a matte black powder coating finish encasing the interior filter, held in place by neoprene padding. Easy Access Design Slide lock hatch system provides quick access to the inner chamber's filter slot for direct and speedy replacement, accepting standard-sized MERV filters. High Efficacy Protection Review: great add on - Great add on to filter the air passing through! Review: Nice but lacking mounting features - This is a nice product, although at the end of the day it’s just a metal box with two holes, a door, and a filter slot. I bought two to use for my coffee roasting business and put them directly above my roasters with electrostatic filters to trap chaff and dust before the fan. My criticism of the product is that it has no mounting tabs, so I ended up having to get sheet metal screws and drill holes into the body of the filter box. It works but now my filter boxes have permanent holes, and I had to research, design, purchase, and implement my own mounting solution. ## Features - A duct filter box designed for use with inline fans to circulate fresh air and block contaminants. - Built with 1mm thick cold-rolled steel and aluminum duct flanges, able to withstand extreme weather. - Slide lock door gives easy access to inner chamber while soft neoprene layer creates dust-free seal. - Includes a standard MERV 13 filter that traps particles like viruses, dust, pollen, and mold spores. - 23.46 x 8.42 x 11.73” | Fits 10” Inline Fans | 2400 CFM Maximum | Accepts 14 x 20 x 1” Filters ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0921RKL8H | | Best Sellers Rank | 129,560 in DIY & Tools ( See Top 100 in DIY & Tools ) 613 in Registers, Grilles & Vents | | Brand | AC Infinity | | Brand Name | AC Infinity | | Compatible Devices | CLOUDLINE S10, CLOUDLINE T10 | | Compatible Hvac Systems | residential | | Compatible devices | CLOUDLINE S10, CLOUDLINE T10 | | Country Of Origin | China | | Customer Reviews | 4.6 out of 5 stars 27 Reviews | | Filter Mounting Type | Slide In | | Filter Shape | Rectangular | | Item Dimensions L x W x Thickness | 57.2L x 35.4W x 29.4Th centimetres | | Item Weight | 7.94 kg | | Item weight | 7.94 kg | | MERV Rating | 13 | | MERV rating | 13 | | Manufacturer | AC Infinity | | Manufacturer Part Number | AC-AFB | | Material | Alloy Steel , Aluminium | | Material Type | Alloy Steel, Aluminium | | Model Number | 819137021723 | | Number of Items | 1 | | Product Grade | new | | Product dimensions | 57.2L x 35.4W x 29.4Th centimetres | | UPC | 819137021723 | | Unit Count | 1.0 count | ## Product Details - **Brand:** AC Infinity - **Compatible devices:** CLOUDLINE S10, CLOUDLINE T10 - **Item weight:** 7.94 kg - **MERV rating:** 13 - **Manufacturer:** AC Infinity - **Material:** Alloy Steel, Aluminium - **Number of items:** 1 - **Product dimensions:** 57.2L x 35.4W x 29.4Th centimetres - **Product grade:** new - **UPC:** 819137021723 ## Images ![AC Infinity Inline Filter Box 250mm with High Efficacy Filter, Whole House HVAC Filtration Kit, Fits 250mm Inline Duct Fans for Fresh Air Intake and Ventilation, 10-Inch - Image 1](https://m.media-amazon.com/images/I/51kvho-dPuS.jpg) ![AC Infinity Inline Filter Box 250mm with High Efficacy Filter, Whole House HVAC Filtration Kit, Fits 250mm Inline Duct Fans for Fresh Air Intake and Ventilation, 10-Inch - Image 2](https://m.media-amazon.com/images/I/51keHQnx4lL.jpg) ![AC Infinity Inline Filter Box 250mm with High Efficacy Filter, Whole House HVAC Filtration Kit, Fits 250mm Inline Duct Fans for Fresh Air Intake and Ventilation, 10-Inch - Image 3](https://m.media-amazon.com/images/I/51NyArbfr0S.jpg) ![AC Infinity Inline Filter Box 250mm with High Efficacy Filter, Whole House HVAC Filtration Kit, Fits 250mm Inline Duct Fans for Fresh Air Intake and Ventilation, 10-Inch - Image 4](https://m.media-amazon.com/images/I/61yP1T29OcL.jpg) ![AC Infinity Inline Filter Box 250mm with High Efficacy Filter, Whole House HVAC Filtration Kit, Fits 250mm Inline Duct Fans for Fresh Air Intake and Ventilation, 10-Inch - Image 5](https://m.media-amazon.com/images/I/612-66ho2yL.jpg) ## Available Options This product comes in different **Model** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ great add on *by T***3 on 9 March 2026* Great add on to filter the air passing through! ### ⭐⭐⭐⭐ Nice but lacking mounting features *by B***D on 21 June 2024* This is a nice product, although at the end of the day it’s just a metal box with two holes, a door, and a filter slot.

Need to use off brand filters *by M***T on 29 September 2024* Like stated, it’s a nice filter holder. Built well. Down side is that ac infinity doesn’t sell a replacement filter that I know of. Had to measure out the one that came with the holder and get replacements from the hardware store. ## Frequently Bought Together - AC Infinity Inline Filter Box 10" with High Efficacy Filter, Whole House HVAC Filtration Kit, Fits 10-Inch Inline Duct Fans for Fresh Air Intake and Ventilation - AC Infinity CLOUDLINE PRO S10, Quiet 10” Inline Duct Fan with Speed Controller - EC Motor Ventilation Exhaust Fan for Heating Cooling Booster, Grow Tents, Hydroponics - AC Infinity Flexible 10-Inch Aluminum Ducting, Heavy-Duty Four-Layer Protection, 8-Feet Long for Heating Cooling Ventilation and Exhaust --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kr/products/526944587-ac-infinity-inline-filter-box-250mm-with-high-efficacy-filter](https://www.desertcart.kr/products/526944587-ac-infinity-inline-filter-box-250mm-with-high-efficacy-filter) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-05-25*
