Best Bathroom Exhaust Fans of 2026

Three and three-eighths inches of housing depth decides more of these installs than any airflow figure on the box. In a hall bath with a shallow ceiling cavity, most fans mean cutting joists or dropping the ceiling; this Panasonic slips into the space that is already there, and it is the shallowest fan in this group. That, plus three selectable airflows and a 0.9-sone rating, is why it is the one we recommend first.

Pick-A-Flow is the part we appreciate most. A switch on the unit sets the fan to 50, 80, or 100 CFM, so one model covers a powder room or a full family bath, and you can turn it up later if the room turns out bigger than you judged. Since a fan can only move what the duct allows, going straight to 100 CFM on a long, sagging flex run buys less than the label suggests — keep the run short and the duct rigid where you can.

The duct collar is the one thing to sort out before the ceiling is open. It is not shaped like a plain 4-inch round fitting, so a standard round duct may need an adapter to seat properly. That is a small part and a second trip to the hardware store, not a reason to pass, but it is the sort of detail that turns a forty-minute swap into an afternoon if you find out halfway through.

Panasonic also covers the motor for six years, matched here only by the big WhisperCeiling, and the ceiling-or-wall mounting matters more than it sounds in a basement bath where the ceiling is concrete or already crowded with ductwork. What keeps this at the top for us is the combination rather than any single figure: shallow enough for the ceilings that force compromises, quiet enough that nobody reaches to turn it off, and adjustable enough that you are not guessing airflow before you know the room.

Two hundred and ninety cubic feet per minute is more fan than most bathrooms can use, and that is exactly the point. This is the answer for the room where a 110 CFM unit runs through a whole shower and the mirror still fogs: a big primary bath, a bathroom with two shower heads, or a space with a vaulted ceiling that traps steam up high where a small fan never reaches it. At roughly one CFM per square foot, it is built for a room in the 250 to 300 square foot range.

What surprises us is how little noise comes with that much air. Two sones puts it quieter than most of the fans here, despite moving close to three times the airflow of our top pick, and the wide double-tapered blower wheel moves the volume without the roar the number would suggest on a lesser fan. The galvanized housing is heavy-gauge and rust-resistant, the bracket adjusts up to 24 inches to span joists, and it is rated for continuous operation — so a timer or humidity control can leave it running without worry. Panasonic covers the motor for six years.

The catch is everything around the fan. A 290 CFM unit needs a larger ceiling opening, a bracket span across the joists, and ductwork that can actually carry the air; on a long run of 4-inch flex duct you spend the money and collect a fraction of the benefit. We treat this as a planned project rather than a Saturday swap, and it only makes sense when the room and the duct behind it are both big. In a standard hall bath it is simply more fan than the space can use.

If your attic is a foot of blown insulation and a maze of flex duct, this spec matters more than any other: the AE80B installs entirely from below. The housing mounts to the joists through the existing opening, the wiring and duct connect at the fan, and nobody climbs into the fiberglass. For a lot of houses that is the difference between replacing a noisy fan this weekend and living with it for another five years.

At 0.7 sones it is the quietest fan in this group, and 80 CFM covers a bathroom up to about 75 square feet, which is most of them. Broan's TrueSeal damper closes the duct when the fan is off, stopping the backdraft of attic air and the heat loss that rides with it — a small thing on a cold morning and a real one over a winter. The non-metallic duct connector is in the box, and the fan is listed for use over a tub or shower on a GFCI-protected circuit, so you can put it where the steam actually is.

One speed is the compromise we accept. There is no switch to dial the airflow down for a quick shower or up for a steamy one, so the room has to be right for 80 CFM going in — measure it rather than guess. The AC motor draws around 25 watts, more than the DC fans here, which matters mainly if you leave it running for hours at a stretch rather than the twenty minutes after a shower.

Where it earns its place is the ordinary case: a builder-grade fan that has rattled for a decade, a ceiling you would rather not open, and a homeowner who wants the job done in an afternoon. It is not the most capable fan here and it is not the cheapest, and neither of those is why we keep recommending it.

Every other fan on this page announces itself with a square white grille. This one reads as a recessed can light, and in a bathroom that already has a row of cans in the ceiling it disappears into the pattern instead of interrupting it. Broan matched the trim to the major recessed-light lines, so the match is close rather than approximate, and that is the whole reason to pay attention to this model.

Behind the trim it is a 70 CFM centrifugal fan at 1.5 sones with a 4-inch round duct connector and a 75-watt bulb socket in the middle. Mid-pack airflow for this group, quiet enough that you notice the light more than the motor. It is also the pick here for a shower stall that wants its own light directly overhead rather than a glow from across the room.

The bulb is not in the box, and the fixture takes a standard R30 or BR30 rather than an integrated LED. We count that as a plus: you choose the color temperature, a warm bulb over a shower beats a cool panel, and replacing one costs pocket change. Budget for the bulb and you will not be making a second trip with the ceiling already open.

Our reservation is the physical size and the airflow together. The housing stands 6-7/8 inches tall, so it wants a 2x8 joist bay and simply will not go into a shallow soffit, and 70 CFM is a small-to-medium bathroom number — with the light on you are also adding a little heat to the room the fan is trying to dry out. Treat it as the right answer for a hall bath or a shower stall, not for a big primary bath with a soaking tub.

Eighty CFM at 1.5 sones for the least money of any 80 CFM fan here is the entire argument, and it holds up. The housing is galvanized steel rather than the thin plastic you brace for at this end of the market, the grille is plain white and low-profile, and the whole thing installs from below with no attic access. It is HVI and UL certified and Energy Star qualified, and it is listed for use over a tub or shower on a GFCI-protected circuit.

The roomside install is why it keeps turning up in rentals and flips. The no-cut housing fits most standard openings, the 4-inch duct connector usually matches what is already in the ceiling, and the swap happens without anyone going into the attic. At 80 CFM it covers a bathroom up to about 85 square feet, which puts a normal hall bath comfortably inside its range with something to spare for a long duct run.

The detail worth flagging is the plastic collar where the duct attaches. Support the duct so its weight hangs on a strap rather than on the collar, and do not force a stiff length of flex over the tabs. Done that way this is a lot of fan for the money; forced, the collar is the first thing to give, and then you are improvising with tape and glue above a ceiling you just closed.

A seven-inch fan sitting in an eight-inch opening is not a standard size, and if that is what your ceiling has — common in manufactured and mobile homes — the measurement is the whole purchase. A regular 10-inch-square bath fan means cutting the ceiling wider and patching drywall around it. This one drops into the hole that is already there and covers it with a round white grille, and that is a much shorter afternoon.

For that job we think it is the right answer. Fifty CFM and a 1.0-sone rating suit a small bathroom, the grille sits flush and unobtrusive, and it runs off an ordinary wall switch, which is what you want when you are matching an existing setup rather than adding controls. It is also the least expensive way to stop a rattling original fan without opening a remodeling project.

Two things to check before ordering. The motor and duct assembly add about 6-1/2 inches above the grille, so measure the ceiling depth — in a manufactured home with a shallow roof cavity that is the difference between fitting and returning it. And noise depends less on the fan than on the duct behind it: a short, rigid, well-supported run lets a 1.0-sone fan actually run near 1.0 sones, while a loose flex duct on a thin ceiling panel makes any fan sound worse than its rating.

Fifty CFM is a small-bathroom number and it is worth being blunt about that: in a family bath with a hot shower running for ten minutes, this fan is doing roughly half the work an 80 CFM unit would. Where it belongs is a powder room, a half bath, a small hall bath, or a laundry room that needs air moving and nothing more dramatic than that.

In that role it is a quietly good buy. A full sone rating of 1.0 puts it among the quietest fans here, at about the money the budget 80 CFM fan costs, and the galvanized steel housing resists the rust that eventually finishes off cheap bathroom fans. The grille is minimal enough to read as a vent rather than an appliance, which is more than several fans in this group manage.

Installation is the no-cut, roomside kind, with the ceiling opening listed at about 7-3/4 by 7-1/2 inches, and the grille comes off on spring clips for cleaning. Handle those clips gently — they are the part that snaps if the cover is pulled off at an angle, and a replacement grille is an irritating purchase. The rest of the fan is ordinary in the best way: a wall switch, a 4-inch duct, and nothing to program.

Three sones is loud, and there is no useful way to write around it. This is the fan you hear from the next room, and that is the trade Air King made to sell 90 CFM cheaply: a straightforward AC fan in a plastic housing with a snap-in mount and a 4-inch duct collar. Compared with the 0.7-sone Broan here it is a different category of object, and you should buy it knowing that.

What the noise buys is real airflow for modest money, a backdraft damper on the duct collar, and a housing rated for continuous operation and for ceilings insulated to R-40. The grille is a plain 10-inch square that wipes clean in a second, and the snap-in system makes short work of a replacement in an existing opening — a job that goes faster than on any other fan here.

It is also the one fan in this group where the build feels basic. The plastic grille is open enough that you can see the fan turning behind it, and the housing flexes more than the steel ones. None of that changes how it moves air, but it is why we keep it out of a bathroom you have just finished tiling and put it in the ones you have not.

Where it earns its place is everywhere quiet is not the point: a laundry room with a litter box, a basement bath, a workshop bathroom, or a rental where a fan running is a feature because it covers other noise. In those spots 90 CFM at a budget price is the sensible answer, and three sones is a fair trade for getting it.
