The Broan GLA2303SS is a 30-inch under-cabinet range hood with a 350 CFM internal blower, three fan speeds, two-level LED lighting, and convertible venting that works ducted or ductless. It fits a standard 30-inch cooktop, mounts under your upper cabinets, and sells for around $319 in stainless steel. If you cook on an electric or a standard gas range and want a clean, simple hood that clears steam and grease without much fuss, it covers the basics well. Here is what it does, how it performs, and what to know before you install it.
What you get with the GLA2303SS
The GLA2303SS is part of Broan’s GLA2 Series. It is a 30-inch wide hood built to sit under a standard upper cabinet, above a 30-inch range or cooktop. The “SS” at the end of the name means stainless steel.
At a glance, the hood pulls up to 350 cubic feet of air per minute, runs at three speeds, and lights your cooktop with a built-in LED strip that has two brightness levels. It can vent outside through a duct or recirculate air back into the room with a charcoal filter. The controls are flat tap-touch buttons across the front, so there are no dials or remote to deal with.

Is 350 CFM enough suction?
For most home kitchens, yes. 350 CFM moves enough air to clear steam, smoke, and cooking smells from a 30-inch electric range or a standard gas range. A simple way to size a hood is to match the airflow to how much heat your burners put out. A common guide for gas is about 1 CFM of airflow for every 100 BTUs. A typical four-burner gas range puts out somewhere around 30,000 to 40,000 BTUs, so 350 CFM lines up well with it.
Where 350 CFM starts to feel light is with heavy, high-heat cooking. If you have a pro-style gas range above 50,000 BTUs, do a lot of searing or wok work, or cook in an open-plan kitchen where smells drift into the living room, a stronger hood in the 600 CFM range will clear the air faster. For everyday boiling, frying, and roasting on a normal range, the GLA2303SS keeps up fine.
One thing that affects real-world suction as much as the CFM number is the duct. A short, straight duct run with smooth metal pipe lets the hood move close to its rated airflow. A long run with lots of bends, or flexible ribbed duct, chokes it down. Keep the path as short and straight as you can, and size the duct to match the hood rather than pinching it down to fit an old, smaller pipe.
There is one more point worth knowing for newer, tightly sealed homes. Make-up air is the fresh air that has to come in from somewhere to replace what the fan sends outside. Very strong hoods can pull hard enough to need a dedicated make-up air supply under local code, but at 350 CFM the GLA2303SS normally sits well under that line. If you are not sure how your area handles it, your installer or local code office can confirm.
A small habit helps too. Turn the hood on a few minutes before you start cooking and leave it running a few minutes after you finish. Starting early catches the first rush of steam, and running it afterward clears the last of the grease and smell that still hangs in the air.
How loud is it?
On its lowest working speed, the hood is rated at 1.5 sones, which is quiet. A sone is a plain way to measure loudness as a person actually hears it, and 1.5 sones is roughly the hum of a quiet refrigerator. At low speed you can run the hood and still hold a conversation or hear the TV, and this is the speed you will use most of the time.
On high, it climbs to about 7 sones, which is clearly louder, closer to a strong bathroom exhaust fan. You reach for high speed when you are searing meat or boiling a big pot and want fast clearing, then drop it back down once the air is clear. Having three speeds lets you match the noise to the job instead of living with one loud setting.
How well does it light the cooktop?
The GLA2303SS has a built-in LED light bar with two brightness levels. The lower level works as a soft night light or for a gentle simmer, and the higher level gives you bright, even light across the whole cooktop. The LED modules run cool, use little power (around 5 watts), and last for years, which is why Broan backs the light with a 3-year warranty while the rest of the hood carries 1 year.
Good lighting matters more than people expect. A well-lit pan makes it easier to judge color and doneness, and it cuts the shadow your own hands throw over the food while you work. On an older hood with a dim or yellow bulb, this is often the upgrade you notice first.
Ducted or ductless: which should you pick?
This hood is convertible, so you can set it up either way, and the better choice is ducted whenever you can manage it. Ducted venting sends grease, heat, moisture, and smells all the way outside through a duct. That keeps your kitchen cooler, drier, and cleaner, and it stops cooking steam from adding humidity that can feed mold over time. The GLA2303SS vents up through the top or back through the wall, using a 3.25 by 10 inch rectangular duct or a 7 inch round duct.
Ductless venting, also called recirculating, is the backup for when you cannot run a duct outside, which is common in apartments and on interior walls. The hood pulls air through a charcoal filter that traps smells, then pushes the cleaned air back into the room. You buy the charcoal filter separately (Broan model HPF30) and swap it every few months. Ductless is easier to install, but it moves less air and does not remove heat or moisture, so pick ducted if the option is there.
Tip: If you are replacing an old hood, check which way the existing duct runs, up through the cabinet or back through the wall, before you start. The GLA2303SS handles both, but knowing your setup ahead of time saves a trip back to the store.
Filters and cleaning
The hood uses two micro-mesh grease filters that pop out from underneath. They are dishwasher safe, so you can pull them and run them on the top rack every couple of weeks, more often if you fry a lot. Clean filters keep the airflow strong and cut the chance of grease building up inside the hood, which is both a performance and a safety point.
The stainless steel body wipes down with a soft cloth and a little stainless cleaner. Wipe along the grain of the metal, not against it, to avoid streaks and fine scratches. If you run the hood ductless, remember the charcoal filter is a separate part that gets replaced, not washed, so keep a spare on hand.
Do not run the hood for long without the grease filters in place. They are what stops grease from coating the blower and the inside of the housing, and a greasy fan both moves less air and runs louder. Popping them back in after they dry is part of the routine.
What you need to install it
The GLA2303SS mounts under a standard cabinet over a 30-inch range. It stands 6 inches tall, just under 30 inches wide, and about 19.7 inches deep, so it tucks under most upper cabinets without hanging past the cabinet face. Before you buy, measure your cabinet opening and look at the duct path you have to work with.
A few things to plan for before you start:
- Power. The hood is built to be hardwired to a 120-volt circuit. If you would rather plug it into an outlet, Broan sells a plug-in power cord kit (model HCK44) separately.
- Mounting height. Follow the install manual for the minimum clearance above your cooktop. As a general guide, about 20 to 24 inches above an electric cooktop gives good capture without the hood getting in your way, and gas ranges usually want a little more room.
- Duct path. Decide early whether you are going up through the cabinet or back through the wall, and have the right size duct and an outside wall or roof cap ready to go.
- Accessibility. If you need the hood to meet ADA mounting rules, an ADA compliance kit is sold separately.
If you are comfortable with basic wiring and ductwork, this is a doable weekend job. If not, an installer can usually handle it in a couple of hours. You can confirm the exact clearances and duct details on the manufacturer’s product page before you commit.
Features that make daily use easier
The flat tap-touch controls sit on the front edge and wipe clean in a single swipe, with no knobs to trap grease. A delay-off setting lets the fan keep running for a set time after you tap it, so it finishes clearing the air on its own and then shuts off. It is a small touch that saves you from standing around waiting to turn the hood off.
The GLA2303SS is also ENERGY STAR certified and HVI certified. That means its airflow and efficiency have been measured and verified under a standard test, so the 350 CFM and sone numbers are tested figures rather than marketing claims printed on the box.
Sizes, finishes, and the rest of the GLA2 series
The 30-inch GLA2303 comes in three finishes to match different kitchens: stainless steel (GLA2303SS), white (GLA2303WW), and black stainless (GLA2303BLS). The hood itself is identical across the three, so the only choice is the look.
If your cooktop is wider than 30 inches, Broan makes a 36-inch version in the same series, the GLA2363, in the same finish options. Measure the width of your range and your cabinet opening and match the hood to it, since a hood that is too narrow leaves the edge burners under-covered.
What the warranty covers and what is in the box
Broan covers the GLA2303SS with a 1-year limited warranty on parts and labor, and a longer 3-year warranty on the LED light module, since the light is the part meant to keep going well past a single year of daily use. Keep your receipt, because the warranty period is counted from the purchase date.
In the box you get the hood, its two micro-mesh grease filters, and the mounting hardware. The parts you may need to buy on top, depending on your setup, are the charcoal filter for ductless use (HPF30), the plug-in cord kit if you are not hardwiring (HCK44), and the ADA kit if you need it. If any of those apply to you, add their cost to the roughly $319 sticker price so the real total is not a surprise.
Who is it a good fit for?
The GLA2303SS suits a home cook who wants a reliable, good-looking hood for a 30-inch range without paying for pro-level power. At around $319 it sits in the affordable range while still giving you LED task lighting, dishwasher-safe filters, quiet running at low speed, and the freedom to vent either way. For a kitchen remodel on a budget or a straight swap of a tired old hood, that is a sensible mix.
It is less of a match if you run a high-BTU pro range, or if you want extras like a handheld remote, a timer display, or Wi-Fi control. For standard electric and gas cooking, though, it hits the practical sweet spot: enough suction, low noise at the speed you actually use, bright light, and simple upkeep.
Conclusion
The Broan GLA2303SS is a solid, no-nonsense 30-inch under-cabinet hood: 350 CFM of airflow, three speeds, a quiet 1.5-sone low setting, two-level LED light, washable filters, and convertible ducted or ductless venting, all for about $319. Set it up ducted if you can, keep the filters clean, and run it a few minutes before and after cooking. For an everyday electric or standard gas kitchen, it clears the air well and is easy to live with.
Frequently asked questions
Is the Broan GLA2303SS ducted or ductless?
Both. It is convertible. You can vent it outside with a 3.25 by 10 inch or 7 inch round duct, or run it ductless with a separate charcoal filter (model HPF30) that sends cleaned air back into the room.
How many CFM is the GLA2303SS, and is that enough?
It moves up to 350 CFM, which is enough for most 30-inch electric and standard gas ranges. For a high-output pro range above 50,000 BTUs, a 600 CFM hood would clear the air faster.
Does it come with a charcoal filter for ductless use?
No. The charcoal filter (Broan HPF30) is sold separately. The two micro-mesh grease filters are included, and they are dishwasher safe.
Can I plug it into an outlet instead of hardwiring it?
Yes, but the cord is not included. The hood is built to be hardwired, and Broan sells a plug-in power cord kit (model HCK44) separately if you prefer to use an outlet.
What sizes and colors does it come in?
The 30-inch model comes in stainless steel (GLA2303SS), white (GLA2303WW), and black stainless (GLA2303BLS). There is also a 36-inch version, the GLA2363, for wider cooktops.
