Installing ventilation exhaust fans in your home will help improve indoor air quality for both your health and belongings. As the name implies, these fans exhaust unwanted dirty, humid, and/or stale air from your home to the outside. Typically, an exhaust fan is placed in rooms such as the kitchen or bathroom to remove stale, muggy, or dirty air.

Exhaust fans remove unwanted odors, moisture, smoke, and other pollutants in the air. It also helps control the humidity, which can cause mold to develop. Exhausting steam from the inside helps you control mold in your home, which keeps your furniture and other belongings safe and in great condition by preventing moisture from causing furniture to warp or rot.
Buildings that are not ventilated properly can cause new or aggravate existing health concerns. People with asthma are affected by improper ventilation, while poor air quality can trigger allergies.
The process is simpleーthe exhaust fan replaces stale or foul air with clean, fresh air. We want undesired air out, fresh air in. Fan application dictates the combination of fan specifications a fan must-have. Let’s discuss the four fan specifications we need to consider.
All fans move air from one area to another however, different models of fans are made by manufacturers that cater to different applications. Each model fits a certain demographic of users. One has to sort from all of the models available to match their needs. Below are the differences among models.
There are two ways fans are operated in an exhaust fan: Direct and Belt-driven fans. A direct-driven fan means that the fan is directly attached to the motor. A belt-driven fan means that the fan is connected to a belt, which is then controlled by a motor.
Direct drive fans are typically used for low volume and low static pressure and require little maintenance. Most household exhaust fans are direct drive fans as they are economical and are enough for ventilation requirements for households.
Belt drive fans, on the other hand, move higher volumes of air with higher static pressures. They also perform well in high-temperature applications as the motor doesn’t come into contact with the hot air. For industrial or commercial exhaust, belt-driven fans are the way to go.
Exhaust fans move air in two ways, through propeller or axial. Propeller fans move air through the blades. An example is an electric fan that passes air from the back to the front of the fan. Axial fans suck air through the fan and push air perpendicular to the fan. An example of axial fans is the air-cooling unit of a laptop.
Propeller fans are best suited for large air volumes but low static pressures, which is perfect for residential spaces. Industrial applications call for higher static pressures; this is where centrifugal fans’ design has an advantage. They are quieter than propeller fans and perform well moving high-temperature air.
Fan models are mounted in three common locations: on a roof, in a wall, or in a duct. Differences in fan housing can make installation as easy as possible.
Fan positioning depends on the design of the building and desired airflow. Proper surveying of the building and visualization is needed for proper fan location.
Cubic Feet per Minute (CFM) is measures the volume of air a fan can move. It is computed by taking the size of the room where the exhaust fan will be installed and multiplying it with the frequency of ventilation a certain room needs.
For Kitchen, air needs to be moved 15 times in an hour while for Comfort Rooms, only 5 times in an hour. Once you get the size of the room and multiply that with the frequency, look for a fan that is near but above the value you have computed. Or you can ask your contractor to do the necessary calculations and recommendations for you.
Static Pressure (SP) is the resistance to airflow, or air friction, caused by the air moving through a pipe, duct, hose, filter, hood slots, air control dampers, or louvers. Static pressure is rated in inches water gauge (inWG) or millimeters water gauge (mmWG).
The static pressure for a room is important to ascertain to maximize the flow of air in a room. For kitchens and bathrooms, a static pressure value of 2” SP is enough to cycle the air in the room. Just take note that static pressure is adjusted in conjunction with CFM. Room size and climate need to be taken into account to find the optimal combination of CFM and SP.
Depending on where the exhaust fan will be installed, the sound it generates is of concern. The unit of measurement for expressing sound pressure level is the sone or decibels. Both are linear measurements of sound pressure levels.
For a specific room or application, refer to the suggested limits for room loudness which, can be found online or through a local building code. This is used to determine the acceptable sone range for the application and thus, find a fan that has a sone rating within the range specified. For residences, a sone between 3-9, or 43-60 decibels is acceptable.

Omni has been a trusted electronic appliance brand in the Philippines. And this exhaust fan carries that pedigree. Sporting a cream-white color, this fan would look unassuming once installed in your kitchen or bathroom.
The fan is propeller-type, like most residential fans. With a size of 8 inches, it is big enough to draw air out of the room while small enough to go unnoticed. Fans produce 50dB, which is good for bathrooms that are only used sparingly.
This fan comes with a grill, an added precaution against rodents that might use the air ducts as a passageway inside the house. With good ratings from those who bought, this is a fan that packs a punch.
ShungTian, a brand from China, has produced a fan that is a sleeper. The design lacks inspiration but the specifications are what gives this fan the top 2 spot.
At first look, the design is like any other. You may mistake it with other fans you've seen before but once you operate it, it sets itself apart. at 40dB, it is a quiet fan, even able to move 8.5m3/min of air. Now that's a performer!
It is wall-mounted and would work best for both the kitchen and bathroom. Getting this, you won't even notice you installed it, given how quiet and how clean the air you are breathing once you are using it.
If you have a mansion that you want to outfit with something that packs a little more punch than your regular exhaust fan, look no further. This fan from Caron has all the muscle-power that you need to fulfill your needs.
Able to move a whopping 22.5 m3/min, this is a workhorse. That amount of strength comes at a price, a loud one, producing 52dB. It is roof installed and kept well away from the inside, keep noise to a minimum.
This fan fits best for houses with large rooms or industrial applications. Not all may need this fan, but for those that do, this fan will do wonders for your ventilation.
Omni produced this exhaust fan with one thing in mind: discreetness. Mounted in the ceiling, it almost sits flush with it.
The fan is a centrifugal one and draws air through its vents and is flushed out perpendicularly through a duct which can be routed away from the room. It produces 42dB and operates quietly while able to output 8.2m3/min of air.
This works wonders for the bathroom, with its design as it is unobtrusive and blends well with the ceiling. It moves air well, making this a bathroom powerhouse without knowing that there is an exhaust fan installed.
Another one from Omni, this fan is the bigger brother of our top 1. Design-wise, they are almost the same, but the specifications for this one are of a higher caliber.
Those wanting more air suction should find this one more than enough. Sporting a propeller-type fan, this 10-inch ventilation draws out 12m3/min of air. But with size comes some drawbacks. At 52dB, this isn't a quiet fan.
A bigger fan entails bigger holes for rodents to go in and out. Omni put some grills to ensure that your home is safe from any infestation. If you have a medium-sized bathroom or kitchen, this wall-mounted exhaust fan is for you.
If asked what is an exhaust fan, this is what usually comes to mind. Seen in most bathrooms and kitchens, this solution from Standard has been a staple throughout the years.
The design is unassuming and deceptively simple but as they, "don't fix what ain't broke." It is able to move 12m3/min of air volume while keeping noise levels at 45dB, now that is efficiency.
It is louver-type, with the slides closed whenever the fans are not operational. If an exhaust fan was able to bring you back nostalgic memories while delivering outstanding performance, get this one.
Royu is a staple in house improvements and equipment and this fan is a worthy addition. Its 10-inch cut-out is big enough to look powerful, but compared to our other fans in the top 10, it lacks in its ability to draw air.
It is a propeller-type fan and draws 6.5m3/min of air. This fan exemplifies that it's not always about the size but also the performance. Even with the lower power, it produces 50dB which is quite loud.
One feature that this fan offers is the included grills which are sure to catch dust and big debris that may go inside the rotors. If you want to look powerful but only care about good-enough performance, this fan is for you.
The smaller brother to our top 6, this 6-inch fan has been a choice for people wanting the iconic looks of Standard exhaust fans but wanting a mellower and gentler performance from their bigger fans.
The small, compact factor is able to move 4.5m3/min of air volume while keeping noise levels at 40dB, offering good ventilation at discreet noise levels.
Same as its brother, it is louver-type with smaller vents that match the fan's power. Standards line offers good performance, so get this fan for applications that require lesser demands.
This fan from Royu might be small but it is capable enough to move air. So small that you might mistake it for flat light. With grills built-in, you are assured that no big objects will get stuck inside the propeller.
Being this small, a propeller fan works best. Sporting a meager 6 inches, it moves only 2.5m3/min but it is enough for small rooms such as a storage area or a bathroom. For rooms that need adequate ventilation and are seldom used, Royu has produced this small fan for your needs.
This fan got the looks and the technology but not the power that some of the fans in our top 10. But for applications that call for minimal air movement, this fits the bill.
Only able to move 2m3/min of air volume, this isn't a workhorse. However, it is able to operate quietly, only producing 40dB, on par with the quietest fan in this list.
For rooms that are small enough, around 5-10sqm, this fan would be more than enough to clear the room air. Just don't expect livable standards if you plan on staying in the room where this fan is operating.
