## Overview

The Atomic Innovations Air Duct Screen and Carbon Filter is a dual-layer, high airflow filter designed for 4-inch air ducts and vents. Featuring a MERV 4 rated carbon filter and a durable weather-resistant polymer frame, it effectively reduces dust, small particles, and light odors. Ideal for grow tents, greenhouses, and light-duty commercial or residential use, this USA-made filter ensures cleaner air intake with easy installation and reliable performance.

## Description

Made in USA. This fiber screen + carbon filter fits perfectly into 4 inch diameter air ducts. Unit has an outer insertable diameter of 3.95 inches with a short faceplate of 4.21 inches. It will prevent small objects and particles from entering your duct system. Carbon filter layer has an estimated MERV 4 rating and will also reduce some odors. Rigid polymer frame is weather resistant. Works well with greenhouses, small shops, and other light duty filtering applications where small objects, particles, and odors are a nuisance. Easily secured at intake with duct tape or hose clamp (not included). Disclaimer: This product is not intended for use with hazardous gases. Max Temperature 180 F. Product works best in duct systems located near the fan/blower and may not allow sufficient airflow if used in conjunction with very low powered fans/blowers. Actual filter MERV rating may vary. A portion of this product is 3D printed and may show layer lines or cosmetic imperfections that will not affect product function.

Review: Perfect - Does its job, filters my incoming air pretty good
Review: Great as Pre-Filter for Box Filters - Used as pre-filter on my fresh air intake system (Merv 13 filter box & duct fan). Fit perfectly inside 4” flex duct which was attached to wall penetrated vent duct. Plan to clean and reuse.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Perfect
*by R***D on December 2, 2025*

Does its job, filters my incoming air pretty good

### ⭐⭐⭐⭐⭐ Great as Pre-Filter for Box Filters
*by M***S on November 9, 2025*

Used as pre-filter on my fresh air intake system (Merv 13 filter box & duct fan). Fit perfectly inside 4” flex duct which was attached to wall penetrated vent duct. Plan to clean and reuse.

### ⭐⭐⭐⭐⭐ Useful for more than its intended purpose
*by F***O on September 14, 2024*

If you live far away from any city ,like I do,chances are you have a septic,and your septic has a vent {or else it wont work}. Well we don't want that ,but every so often that vent will remind you what it's attached to, PHEW in no uncertain terms PHEW !!! Most vent pipes are 4in, which is great because this item is just the right size for the job.. If your vent is straight out the ground with a PVC rain cap you're in luck ,2 90 degree elbows to make a "gooseneck " is even better,and one 4in coupling to join the elbows together. These fittings you can get on Amazon along with a bag of. fish tank granulated charcoal and a charcoal pad type filter. Bear with me we're almost there. Disconnect the last elbow,{or buy2 if needed} insert the 4 in duct filter into the bottom leg of the down pointing elbow ,and secure with 2 screws 1 per side, use an elbows to press down on the charcoal pad, and cut out out a 4in circle. Now its assembly time , pour the loose charcoal into the down pointing elbow, ,press the pad circle on top of the loose charcoal and reassemble the gooseneck ,add 2 more screws to the joint where the elbows are joined and you're assembly is complete . The triple dose of charcoal will tame even the most ferocious, exotic "fragrances" Lastly you can replace the mat circle and the granulated fill when your tank is pumped or recharge it by applying heat with a hair dryer. NOW you're done. PS it took longer to write this, than it took to do it.
