What do I need to know to purchase one of your Diffusers?
We recommend measuring the size of the air duct opening to make sure the AC Vent Cover neck will fit into the opening. Our product dimensions are categorized by the neck of the AC Vent Cover and not by the face of the AC Vent Cover. Below is a quick flyer of what to measure for on an AC Vent Cover after removing it.
Check out our catalogues to see which Vent Cover neck and face sizes would fit your duct opening:

What is the difference between an AC Vent Cover and a Linear Slot Diffuser?
There is no difference between Vents, Diffusers, Registers, Grilles. They are all just different names used by different industries for AC Vent Covers. AC Vent Covers are the "Face" of your AC Ducts which is the inside of the black box you see when you remove your AC Vent Covers. AC Vent Covers' main two functions are to cover the duct and also direct the airflow as it enters the room.
How to install a Linear Slot Diffuser AC Vent Cover?
The method of installation is through the pre-drilled holes inside of the diffuser. Once the vent is in place, you will fine them by opening the dampers (restricting the air temporarily). We recommend a drill with an extension to install the metal perforating screws that will be included in the vent. You will receive the Linear Slot Diffuser in the OPEN position. The black blades will be touching each other and is in the fully open position. The airflow will go through the sides. When you separate the black blades, you will be restricting the airflow. You can do that manually with your fingers, then you will see the predrill holes and with a drill and an extension, you will screw the 4 metal perforating screws through the sides. To bring it back to an OPEN position, like any other Linear Slot Diffuser you will need a tool, like a flat plastic spatula, knife, anything that is flat and rigid. You will need to insert the tool between the black blade and the white face of the diffuser and pressure it towards back to the center.

What does CFM stand for?
CFM stands for Cubic Feet per Minute and is the most common way to measure airflow. We measure CFM assuming an Effective Velocity of 9.8 ft/s because it is the industry standard. Areas are measured in square units (like square feet), and Volumes are measured in cubic units (like cubic feet). Rooms are measured in Cubic feet and a room by industry standards should be cooled in under 4 minutes (approx 3.75 mins), so a single vent to a 1000 sqft room should have a CFM rating of at least 267 CFM or higher.
How much CFM for each Linear Slot Diffuser AC Vent?
Do your Linear Slot Diffuser AC Vents come in different colors?
At the moment, we only offer our AC Vent Covers in standard ceiling white. We are able to keep our Modern AC Vent Covers reasonably priced is because we manufacture our Vent Covers in bulk, which is why we only offer our Vent Covers in standard ceiling white and which is why we don't do custom sizes.
Are your Linear Slot Diffuser AC Vents paintable?
Yes, while we only offer our AC Vent Covers in standard ceiling white, our vent covers are paintable. We don't suggest painting the vent covers because they are powder coated with an electrostatic paint which makes them easy to clean and very dust resistant. However, if you do choose to paint our vent covers, we recommend using an oil-based paint or epoxy.
Does it require a licensed installer or can I install the Linear Slot Diffuser AC Vent myself?
No it is not required. We recommend you look up your county and state guidelines to see if a permit is required for remodeling HVAC systems. We designed our Linear Slot Diffusers to be installed by the average home-owner because we believe in convenience. That is why we recommend watching our videos and looking up information online and/or seeking the console of a handyman or hvac installer.

Do you offer custom-sized Linear Slot Diffuser AC Vents?
At the moment, we unfortunately do not offer custom-sized Linear Slot Diffusers. To keep our AC Vent Covers at the highest quality and remain at an affordable price, we manufacture our models at scale - meaning we manufacture in bulk. That is another reason why we are always in stock and ready to ship.
How do your Linear Slot Diffuser AC Vents work?
Our Linear Slot Diffusers offer a Directional System with a 3-Way Air Flow Option that can be achieved by changing the direction of the dampers (louvers) by adjusting them with a plastic putty knife or tool with a flat surface. The Inner Mounting Installation Function and Design Avoids Exposing the Duct. The Electrostatic Paint offers a Smooth Finish which makes them Easy to Clean
Can your Linear Slot Diffuser AC Vents be installed on the floor?
Yes. Our Vent Covers were initially designed to be only for ceilings but after changes in design we have adjusted our designs so that they can be easily installed on Ceilings, Walls and Floors. If it fits, it sits - meaning if the duct opening is a 12x4 opening then it doesn't matter if it's on the ceiling, wall or floor, our AC Vent Cover can be installed.
Are your Linear Slot Diffuser AC Vents directional or can the airflow be adjusted?
Our Standard Linear Slot Diffusers offer a 90 degree directional airflow. Our Linear Slot Diffusers offer a 180 degree directional airflow. This directional airflow can be achieved by changing the direction of the dampers (louvers) by adjusting them with a plastic putty knife or tool with a flat surface.
Do your Linear Slot Diffuser AC Vents work as a return?
Yes, all our models can be used to serve as both a supply and as a return AC Vent. However, keep in mind that when being used as a Return vent, we recommend using a 0.8x multiplier on the listed CFM (i.e. listed CFM of 300 would be for the supply and that same vent cover if used as a return vent cover would have the CFM of 240) due to the fact that it is harder to suck in air than it is to push the same amount of air.
How do your Linear Slot Diffuser AC Vents compare to a normal AC Vent?

Electrostatic Paint for a Smooth Finish makes our vents Easy to Clean.

No, we don't carry or sale Plenum Reducers. A Plenum Reducer is like a coupling between a larger Plenum connection to a smaller ac connection. You can purchase plenum reducers at your local Home Depot or Lowes. They aren't too expensive and most associates will know what you are talking about.
