## Overview

The Atomic Innovations Air Duct Screen and Carbon Filter is a dual-layer filtration unit designed for 4-inch air ducts, combining a fiber mesh screen and a MERV 4 rated carbon filter to reduce dust, small particles, and light odors. Featuring a rigid, weather-resistant ASA polymer frame and made in the USA, it offers durable, efficient pre-filtration ideal for grow tents, greenhouses, and light-duty ventilation systems.

## 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: 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.
Review: Simple, Fits Well, Made in the USA - Simple, great design, slots easily and snugly right over my duct fan to keep dust and debris from getting sucked in, and made in the USA. Can't ask for more than that.
