Best Compact Exhaust Fans: Broan 688ES Leads

The best compact exhaust fan for pet owners is the Broan-NuTone 688ES, a 50 CFM ceiling fan rated at 2.0 sones that drops into a 7-1/4 x 7-1/2 in housing with no ceiling cut. If your problem space is a garage or a shed rather than a small room, the iLIVING ILG8SF12V-ST moves 960 CFM through a 12 in shuttered wall opening instead. Get this choice wrong and you buy a fan that either can't be mounted where the smell lives, or roars loud enough that you switch it off and never turn it back on.

That second failure is the common one. A fan you resent running is a fan that does nothing, and odor control depends entirely on runtime.

Best compact exhaust fan for pet owners at a glance

Why picks got cut from this list

Three reasons removed listings before I ranked anything. All three are worth knowing, because they're the same reasons a shopper ends up returning a fan.

1. No published housing dimensions. A compact fan is defined by the cavity it fits. If the listing doesn't state depth, you cannot know whether it clears the joists or the wall studs, and no amount of airflow makes up for that.
2. No airflow or speed figure at all. Several small wall fans publish a diameter and nothing else. Diameter alone tells you the hole size, not the air movement.
3. Nothing about noise or motor type. Runtime is the whole ballgame for odor. A fan with no sone rating, no dB figure and no motor description is a gamble on whether you'll tolerate it.

What survived is deliberately mixed. Two ceiling and wall units built for small rooms, two shuttered wall fans built for garages and outbuildings, and one 80 mm axial unit for venting an enclosure. Notice what this means for the phrase "pet owners": Amazon's own results treat it loosely. None of these five listings is designed, marketed or specified for animal hair, dander or litter odor. I've ranked them on the ventilation figures they publish and left the pet-specific judgment where it belongs, with you and the room you're standing in.

What actually moves pet odor out of a room?

Most guides to the best compact exhaust fan for pet owners compare CFM and stop there. CFM is the wrong lead. It's an airflow figure that only means something once you've paired it with a room volume and a duct path, and it says nothing at all about whether the fan runs long enough to matter.

Three things decide the outcome instead.

• Where the fan can physically go. Odor collects where the animal is, at floor level, near the litter tray or the crate. A ceiling fan two rooms away exhausts nothing useful.
• Noise, because noise sets runtime. 2.0 sones is quiet enough to leave on for an hour after cleaning a tray. A fan rated under 65 dB, as iLIVING states for its 12 in unit, is a garage fan you run in bursts.
• Whether air actually leaves the building. A ducted fan pushes air outside. A ductless or ventless fan moves it around, and the odor molecules stay indoors.

That last point is the trap. The HNRLOY listing describes itself as both "duct free ventless" and "anti-backflow", which are claims about two different installation ideas. Read the housing depth and the mounting type, decide where it's going, then look at airflow last.

1. Broan-NuTone Bathroom Exhaust Fan — Best overall

A 50 CFM ceiling fan quiet enough at 2.0 sones that you'll actually leave it running, in a housing shallow enough to install without cutting.

Best for: a small pet room or powder room up to 45 sq ft with no attic access Skip it if: you need to clear a large open garage or basement

This is the only pick in the set that publishes a sone rating, and that single figure is why it wins. 2.0 sones is a background hum, not an event. Broan states 50 CFM is enough for a room up to 45 sq ft, which covers a powder room, a small laundry area or the kind of utility corner where a litter tray usually ends up.

The housing is the second reason. At 3.63 x 7.5 x 7.25 in with foldable mounting brackets, Broan describes a no-cut installation that doesn't need attic access, and claims the whole job takes 10 minutes. Among these five, it's the shallowest ceiling-mount option by a clear margin, and it's the only one certified to Energy Star. Broan also states the 688ES is made at its Hartford, WI headquarters.

The trade-off against the shuttered fans here is straightforward: 50 CFM is a fraction of the 647 CFM and 960 CFM figures further down this list. This fan is built to clear a small enclosed space slowly and quietly, not to flush a two-car garage. Only two sellers list it, which narrows your options if the first one isn't a fit.

Pros:

• Only pick with a published sone rating, at 2.0
• 3.63 in housing depth, shallowest ceiling option here
• Energy Star certified, unique in this set
• Broan claims a 10-minute no-cut install
• White grille matches common ceiling paint

Cons:

• 50 CFM is the second-lowest airflow figure in the set
• Covers only up to 45 sq ft per the listing
• No warranty stated on the listing
• Just two sellers stock it
• No published weight

2. iLIVING 12" Wall Mounted Shutter Exhaust Fan — Best for beginners

The set-and-forget option: a thermostat and a variable speed dial mean you install it once and stop thinking about it.

Best for: garages and utility rooms where a thermostat should run the fan unattended Skip it if: your only opening is a standard window or a shallow wall cavity

Automation is the beginner-friendly part. iLIVING states a Thermospeed controller with a 32 to 130 F range plus variable speed, so the fan starts itself when the space heats up. For a garage that doubles as a dog's summer spot, that removes the one job people forget: switching it on.

The published numbers are the largest here. 960 CFM, 1650 RPM, 0.6 A, 1/20 horsepower, and coverage stated up to 1400 sq ft. iLIVING describes a galvanized steel frame with aluminum shutters and blades, UL and cUL listing, and noise under 65 dB. It's also the only pick in this group with a warranty on the listing, a 1-Year Limited Component Warranty, and the only one with a stated release year of 2020.

Size is the cost of all that. At 15 x 15 in and 10.2 lb, with a 5.75 in depth, this needs a dedicated wall opening and framing that can carry the weight. "Compact" applies to the depth, not the face. And under 65 dB is a workshop noise level, not a bedroom one, which is exactly the runtime problem I flagged earlier.

Pros:

• 960 CFM, the highest airflow figure in this set
• Thermostat range of 32 to 130 F, unique here
• Only pick with a stated warranty
• UL and cUL listed galvanized steel build
• Variable speed controller included

Cons:

• 15 x 15 in face needs a purpose-cut wall opening
• 10.2 lb, heaviest pick by a wide margin
• Under 65 dB is loud for a living space
• The most expensive pick here alongside the HG Power

3. HG Power Upgraded 10 Inch Shutter Exhaust Fan — Best premium

647 CFM through a 12.4 in square face, with a built-in mesh screen the other shuttered fan here doesn't publish.

Best for: sheds, catteries and workshops that need high airflow with a mesh screen Skip it if: you want a warranty stated on the listing

The mesh screen is the detail that earns this a place. HG Power states the screen keeps debris out and is there for the safety of children and pets, which is the only pet-relevant claim published across all five listings. In a shed or outbuilding where an animal moves freely, a barrier over a 1400 RPM blade is worth more than another 300 CFM.

The rest of the specification sits just below the iLIVING. HG Power states 647 CFM at 1400 RPM with an infinity speed controller, and describes this as a thicker-material revision of an earlier version. The footprint is 12.4 x 6.69 x 12.4 in, so the face is smaller than the iLIVING's 15 in square while the depth runs deeper at 6.69 in. Black finish, which disappears against a dark shed wall better than silver.

What you give up is verification. There's no warranty on the listing, no UL statement, no dB or sone figure, and no published weight, all of which the iLIVING supplies. This is the highest price position in the set with fewer published credentials than the pick below it, and it sells more slowly here too.

Pros:

• Built-in mesh screen, the only pet-safety claim in the set
• 647 CFM at 1400 RPM per the listing
• Infinity speed controller included
• Smaller face than the 12 in shutter fan at 12.4 in
• Black finish suits sheds and garages

Cons:

• No warranty, UL listing or noise figure published
• Highest price position with fewer stated credentials than the iLIVING
• 6.69 in depth, deepest pick here
• No published weight for planning the mount

4. HNRLOY Bathroom Exhaust Fan — Best budget pick

A plug-in 4 in wall or window fan with a 3 in body, for anyone who can't cut a duct or wire a switch.

Best for: renters who need a plug-in wall or window fan and cannot cut a duct Skip it if: you want a single clear airflow figure you can trust

This is the cheapest of the five and the shallowest at 3 x 6 x 6 in. The 3 in body is the whole appeal. It's the one pick that fits a thin wall panel or a window insert without framing work, and it arrives as a plug-in kit with panel, motor, blades and a 1.5 power cord, so there's no electrician involved.

HNRLOY states an EC motor with ball bearings, 10 W draw, 1.5 sones and anti-backflow, which stops stale air drifting back through the blades. For a small laundry room with a litter tray, that combination of low power and a shallow body is a reasonable match.

Here's where I'd hesitate. The title says 130 CFM airflow while the feature text says it "operates at a speed of 95 CFM", and the same listing calls the fan both ductless and anti-backflow. Those figures can't both be the rating, and a ductless fan by definition doesn't send odor outside. There's no weight, no warranty and no count published, and only one seller lists it. Treat it as an entry-level airflow assist, not a specified exhaust solution.

Pros:

• Cheapest pick in this set
• 3 in body, shallowest option here
• Plug-in kit, no wiring or ducting needed
• 10 W draw stated, lowest published in the set

Cons:

• Listing gives two conflicting airflow figures, 95 and 130 CFM
• Described as ductless, so air may not leave the room
• No warranty, weight or count published
• Only one seller stocks it

5. KEYFANCLUB Small Axial Exhaust Fan — Runner-up

An 80 mm axial fan with a duct adapter and a speed dial, for venting an enclosure rather than a room.

Best for: venting a small enclosure, cabinet or litter box housing Skip it if: you are trying to ventilate an entire room

The reason this stays on the list is scale. At an 80 mm frame, roughly 3 in, it's smaller than every other pick by an order of magnitude, and KEYFANCLUB supplies a ducting end that mounts into round pipe. If your odor problem is contained inside a covered litter box, a cabinet or a crate enclosure, this is the only pick that fits inside the thing you're venting.

KEYFANCLUB states 1500 to 4500 RPM with manual speed adjustment from 3 V to 12 V, dual ball bearings for smooth running, and a claimed lifespan of 24/7 operation for over six years. It ships with an AC plug, so you're not sourcing a power supply. The speed range means you can dial it down to something you won't hear, which matters more in a small enclosure than raw output.

Be clear about the limits. There's no CFM figure anywhere on the listing, and an 80 mm computer-style fan is not a room ventilator. The listing's own examples are soldering fume extraction and 3D printer enclosures. Only one seller stocks it, and it's the slowest seller of the five.

Pros:

• 80 mm frame fits inside enclosures no other pick can
• Speed adjustable from 3 V to 12 V, 1500 to 4500 RPM
• Dual ball bearings with a six-year continuous-run claim
• Ducting adapter and AC plug included

Cons:

• No CFM figure published anywhere
• Far too small to ventilate a room
• Only one seller lists it, and it moves slowest here
• Listing targets soldering and 3D printing, not homes

Will a compact exhaust fan fit the space you have?

Measure the depth first. It's the figure that disqualifies a fan before airflow ever enters the conversation, and it's the one most shoppers check last.

Here are the depths in this set, shallowest to deepest:

• HNRLOY: 3 in body, 6 x 6 in face
• Broan-NuTone 688ES: 3.63 in housing, 7.5 x 7.25 in
• iLIVING: 5.75 in, 15 x 15 in face
• HG Power: 6.69 in, 12.4 x 12.4 in face
• KEYFANCLUB: 25 mm frame, 80 mm square

A ceiling between standard joists gives you limited depth and no room to negotiate, which is where the Broan's 3.63 in housing and foldable brackets pay off. Broan specifically says no attic access is needed. A stud wall gives you more depth but a fixed width between studs, so the 15 in face on the iLIVING means cutting into framing, not just drywall.

Weight matters at the top of the range. The iLIVING is 10.2 lb, and that's the only weight published in this set. Ten pounds hanging on a shuttered wall opening needs solid backing behind it. Neither the HG Power nor the Broan publishes a weight, so plan the mount conservatively.

What more money buys in this set

Moving up the price ladder here does not buy quieter, and it doesn't buy smaller. It buys air volume and outdoor durability.

At the entry end, the HNRLOY and the KEYFANCLUB both trade specification detail for a low bar to entry. Plug them in, no wiring, no framing. Neither publishes a verified airflow rating you can plan around.

In the middle sits the Broan 688ES, and it's the only pick where the extra money goes toward acoustics and certification rather than output. 2.0 sones and Energy Star are the return on that spend. If your fan lives in a room you occupy, that's the trade you want.

At the top, the iLIVING and the HG Power both buy steel, shutters, speed control and airflow measured in hundreds of CFM. The iLIVING adds a thermostat, UL listing and the only stated warranty in the set. The HG Power adds a mesh screen and a slightly smaller face. Both are outbuilding fans. Spending the most here gets you the most air and the most noise at the same time, which is the opposite of what a compact exhaust fan for pet owners usually needs indoors.

What the listings do not tell you about pet homes

Not one of these five listings mentions pet hair, dander or litter odor as a design target. That absence is the most useful thing on this page, because it tells you what you'll be handling yourself.

Three gaps to plan around:

• Filtration. None of these picks publishes a filter. An exhaust fan moves air out; it does not capture hair. Expect blade and grille buildup wherever an animal sheds, and expect to clean it.
• Screen protection. Only the HG Power claims a mesh screen with pet safety in mind. If a curious animal can reach a spinning blade, that claim is the one to weight heavily.
• Odor source versus fan location. Odor sits low. Ceiling fans like the Broan pull from the top of the room, so the fan works best when the space is small and enclosed, exactly the 45 sq ft ceiling Broan states.

Runtime is the practical fix for all three gaps. Choose the quietest fan you can install correctly, put it in the smallest room you can close off, and run it for longer stretches rather than short blasts. That's the whole strategy, and it's why the sone rating on the Broan outranks the CFM figures elsewhere in this set.

The verdict

The Broan-NuTone 688ES is the default best compact exhaust fan for pet owners, and it wins on the number nobody else publishes. 2.0 sones and Energy Star certification mean you'll leave it running, and continuous runtime is what actually clears odor from a small room. Add a 3.63 x 7.5 x 7.25 in housing with foldable brackets, no ceiling cut and no attic access required, and it's the pick most people can actually install this weekend.

Two conditions flip that. First, if the smell lives in a garage, shed or workshop rather than a small enclosed room, 50 CFM is not enough and the iLIVING ILG8SF12V-ST takes over with 960 CFM, a 32 to 130 F thermostat, UL listing and a 1-Year Limited Component Warranty. Second, if an animal roams freely near the fan, the HG Power APB25D is the one that publishes a mesh screen and names pet safety, at 647 CFM through a 12.4 in face.

The iLIVING's exact advantage over the Broan is unattended operation. It starts itself on temperature and runs at whatever speed you dial in, which no other pick here does. The Broan's advantage is that you'll tolerate it indoors, and that's the whole game.

FAQ

Is a compact exhaust fan worth it for a pet room?

A compact exhaust fan is worth it when the room can be closed off and the fan is quiet enough to run for long stretches. The Broan 688ES at 2.0 sones fits that description for spaces up to 45 sq ft. In a large open room, a small fan spreads odor rather than removing it, so the room size decides the answer more than the fan does.

What CFM do I need for a small pet area?

The CFM you need depends on room size, and Broan states 50 CFM suits a space up to 45 sq ft. Beyond that, output has to scale up quickly, which is why the shuttered fans here jump to 647 CFM and 960 CFM for garages and sheds. Match the figure to the square footage on the listing rather than buying the biggest number available.

Which is quieter, the Broan 688ES or the iLIVING 12-inch?

Between the Broan 688ES and the iLIVING, the Broan is quieter by a wide margin. Broan publishes 2.0 sones; iLIVING states noise under 65 dB. Those are different scales, but a 2.0 sone rating describes a soft indoor hum while 65 dB describes a workshop. For a room you sit in, the Broan is the only sensible choice of the two.

Does a ductless exhaust fan actually remove pet odor?

A ductless exhaust fan does not send air outside, so odor molecules stay indoors and simply circulate. The HNRLOY listing uses both "duct free ventless" and "anti-backflow" wording, which is worth clarifying before you buy. If removing smell from the building is your goal, choose a fan you can vent through a wall or ceiling to the outdoors.

Do I need a compact exhaust fan or an air purifier?

You need a compact exhaust fan when the goal is pushing stale air out of a small closed space, and a purifier when the goal is capturing airborne hair and dander. None of these five listings publishes a filter, so none of them captures anything. Many pet homes end up running both, with the fan handling odor and the purifier handling particles.

Start with a tape measure, not a shopping cart. Check the depth of the cavity you're mounting into, then the width, then decide whether the room can be closed off while the fan runs. If it's a small enclosed space and the answer to both is yes, the Broan 688ES is the safe default, because 2.0 sones is the only figure in this set that predicts whether you'll actually keep the fan switched on. Everything else here is a bigger fan for a bigger, louder space, and bigger is only better when the room demands it.
