Do I Really Need Make Up Air for My Range Hood?

If you have a range hood in your kitchen, you may be wondering if you need to provide make-up air for it. The answer is maybe. It depends on the type of range hood you have and how it is installed.

If your range hood is vented to the outside, then you don’t need to provide make-up air for it. The exhaust from the range hood will create negative pressure in your kitchen, which will cause outside air to be drawn in through any cracks or openings in the building envelope. This makeup air will replace the air that is being exhausted by the range hood.

However, if your range hood is not vented to the outside, then you may need to provide make-up air for it. This is because the exhaust from the range hood will stay inside your home and create positive pressure. This can cause problems with backdrafting of appliances and possibly lead to unhealthy indoor air quality.

To avoid these problems, you can install a makeup air unit that will bring fresh, outside air into your home to equalize the pressure and help ventilate your kitchen properly.

What Cfm Hood Requires Make Up Air?

In order to determine what size CFM hood requires make up air, you need to first understand how much exhaust your hood is pulling. To do this, you’ll need to measure the static pressure in the ductwork leading to and from your hood. Once you have that number, divide it by the sum of the area of all openings in the hood.

This will give you your CFM rating. Now that you know how many CFMs your hood is rated for, you can easily determine how much make up air is required. For every 1,000 CFMs of exhaust, you’ll need 100 CFMs of fresh air.

So if your hood is rated at 3,000 CFMs, you’ll need 300 CFMs of make up air. Keep in mind that these numbers are just general guidelines – every situation is different and some kitchens may require more or less fresh air than others. But following these simple tips should help ensure that your kitchen stays well ventilated and free of fumes!
