Flem-Air is a wall-mounted supply air filter grille designed to help filter incoming air at the vent before it circulates into the room.
Built for homes, commercial spaces, apartments, schools, and high-traffic environments, Flem-Air helps reduce dust and airborne particles at the point of entry while keeping installation simple and maintenance easy.
Homeowners, contractors, and property managers, can easily see how the units are mounted-no technical drawings required.
Secure the frame over the supply opening so the system has a stable base before the grille is closed into place.
This view shows the filter where people need to understand it most: inside the grille where incoming air is filtered before entering the room.
The finished grille maintains a clean appearance while hiding the filter inside a wall-mounted enclosure.
The Flem-Air Supply Air Filter Grille mounts directly over the wall duct opening. Incoming air moves through the replaceable filter assembly, then through the grille and into the room.
Instead of a technical invention-style diagram, this colorful guide explains the concept in a way homeowners and decision-makers can understand quickly.
Fasten the support frame to the wall so the opening is ready for the grille housing.
Place the filter where air will pass through it before entering the occupied space.
Finish with a clean, modern face while keeping access available for maintenance.
Use the optional filter plan and smart alert concept to simplify replacement timing.
Commercial air handling units are designed to operate at higher tonnage and increased airflow. They function effectively as a secondary filter while maintaining very low static pressure, helping support efficient system performance without restricting airflow.
The grille installs quickly using a side mounted sliding rail that fits securely over the standard T-Bar ceiling grids

FLEM AIR is the vision of innovator Timothy Flemmings Jr., whose 47 years in the HVAC industry revealed the need for a safer, more effective approach to indoor air delivery. After personally experiencing years of upper respiratory infections, he was driven to develop a better solution, one designed to improve air quality, support healthier environments, and enhance HVAC system performance.
The purpose of the grill is to help ensure that indoor environments; homes, workplaces, hospitals, schools, and other facilities supported by HVAC systems are cleaner and safer. By improving the quality and distribution of air, it contributes to healthier living and working conditions across both public and private spaces.
Traditionally, HVAC filters are primarily designed to protect the unit itself, not the individuals using the space. Over time, ductwork accumulates contaminants such as dust, allergens, mold, and airborne particles. These pollutants can be recirculated throughout the environment, negatively impacting indoor air quality and human health.
The FlemAir Filter Grill functions as a secondary layer of filtration within HVAC systems. Positioned at the point of air distribution, it captures residual airborne contaminants that bypass primary filtration, improving air quality and supporting healthier, safer environments.
The FlemAir Filter Grill features a washable MERV 5–6 filter that is well suited for residential supply air grill applications. It serves as an efficient secondary layer of protection, capturing common airborne particles such as pollen, dust, mites, lint, and household dust—typically in the 3.0 to 10.0 micron range. With proper maintenance, this durable filter can last between 5 and 10 years, making it a reliable and long-lasting solution for home air filtration.
Additionally, these filters are washable and reusable, offering a cost-effective and sustainable filtration solution.
Commercial air handling units are designed to operate at higher tonnage and increased airflow (CFM), yet MERV 6–7 filters have been shown to be sufficient for use in supply air filter grille applications. They function effectively as a secondary filter while maintaining very low static pressure, helping support efficient system performance without restricting airflow.
These filters remain washable and reusable, making them a cost-effective and sustainable solution across both residential and higher airflow environments.
