It ensures that moisture doesn&rsquo;t build up in the bathroom, preventing mold from becoming established. It also helps you to get rid of potentially dangerous fumes from cleaning products.<\/p>\n\n\n\n<p>However, over time, you might notice that the bathroom fan is becoming louder, sometimes making unpleasant squeaking noises.<\/p>\n\n\n\n<p><strong>The most common reasons why bathroom fans get noisy are<\/strong>:<\/p>\n\n\n\n<ul>\n<li><strong>There is a build-up of dust and debris in the fan<\/strong><\/li>\n\n\n\n<li><strong>The fan has come loose in the housing<\/strong><\/li>\n\n\n\n<li><strong>The fan might be out-of-alignment, causing it to hit the housing as it turns<\/strong><\/li>\n\n\n\n<li><strong>The fan hasn&rsquo;t been lubricated properly<\/strong><\/li>\n\n\n\n<li><strong>You are living in an apartment complex<\/strong><\/li>\n\n\n\n<li><strong>The fan motor needs to be replaced<\/strong><\/li>\n<\/ul>\n\n\n\n<p>As you can see, there are several reasons why your bathroom fan might be making an unpleasant noise.

Cheaper materials will be more susceptible to rattling from the vibration of the fan.<\/p>\n\n\n\n<p>Also, cheaper materials will break more easily. This will force you to replace the fan more frequently. On cheaper bathroom fans the fan blades are not balanced very well, this causes vibrations and can be the cause of excess noise.<\/p>\n\n\n\n<figure class=\"wp-block-pullquote\"><blockquote><p>I have a list of <a href=\"https:\/\/thetibble.com\/quiet-fan-sones\/\" data-lasso-id=\"66\">8 super quiet bathroom fans.<\/a> They are truly the quietest on the market today and I will keep this list updated<em><strong>.<\/strong><\/em><\/p><\/blockquote><\/figure>\n\n\n\n<h4 class=\"wp-block-heading\">Duct Size<\/h4>\n\n\n\n<p>Another element that can impact on how loud the fan will be is the size of the duct.

This will be in sones (the standard unit of fan loudness rating). The more sones, the louder the fan will be in operation.<\/strong><\/p>\n\n\n\n<p>Most bathroom fans will be around 1.5 to 4 sones, when in operation, but there are some available on the market that rate at about 0.3 sones. You should be able to find how loud the fan is expected to be by looking at the product specifications.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><noscript><img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"729\" src=\"https:\/\/thetibble.com\/wp-content\/uploads\/2023\/07\/Bathroom-exhaust-fan-packaging-and-sones-level-man-checking-bathroom-exhaust-fan-packaging.jpg\" alt=\"Bathroom exhaust fan packaging  and sones level, man checking bathroom exhaust fan packaging\" class=\"wp-image-34197\" srcset=\"https:\/\/thetibble.com\/wp-content\/uploads\/2023\/07\/Bathroom-exhaust-fan-packaging-and-sones-level-man-checking-bathroom-exhaust-fan-packaging.jpg 1000w, https:\/\/thetibble.com\/wp-content\/uploads\/2023\/07\/Bathroom-exhaust-fan-packaging-and-sones-level-man-checking-bathroom-exhaust-fan-packaging-300x219.jpg 300w, https:\/\/thetibble.com\/wp-content\/uploads\/2023\/07\/Bathroom-exhaust-fan-packaging-and-sones-level-man-checking-bathroom-exhaust-fan-packaging-768x560.jpg 768w, https:\/\/thetibble.com\/wp-content\/uploads\/2023\/07\/Bathroom-exhaust-fan-packaging-and-sones-level-man-checking-bathroom-exhaust-fan-packaging-960x700.jpg 960w, https:\/\/thetibble.com\/wp-content\/uploads\/2023\/07\/Bathroom-exhaust-fan-packaging-and-sones-level-man-checking-bathroom-exhaust-fan-packaging-150x109.jpg 150w\" sizes=\"(max-width: 760px) calc(100vw - 24px), 720px\"><\/noscript><img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"729\" src=\"https:\/\/thetibble.com\/wp-content\/uploads\/2023\/07\/Bathroom-exhaust-fan-packaging-and-sones-level-man-checking-bathroom-exhaust-fan-packaging.jpg.webp\" alt=\"Bathroom exhaust fan packaging  and sones level, man checking bathroom exhaust fan packaging\" class=\"wp-image-34197 lazyload\" srcset=\"https:\/\/thetibble.com\/wp-content\/uploads\/2023\/07\/Bathroom-exhaust-fan-packaging-and-sones-level-man-checking-bathroom-exhaust-fan-packaging.jpg.webp 1000w, https:\/\/thetibble.com\/wp-content\/uploads\/2023\/07\/Bathroom-exhaust-fan-packaging-and-sones-level-man-checking-bathroom-exhaust-fan-packaging-300x219.jpg.webp 300w, https:\/\/thetibble.com\/wp-content\/uploads\/2023\/07\/Bathroom-exhaust-fan-packaging-and-sones-level-man-checking-bathroom-exhaust-fan-packaging-768x560.jpg.webp 768w, https:\/\/thetibble.com\/wp-content\/uploads\/2023\/07\/Bathroom-exhaust-fan-packaging-and-sones-level-man-checking-bathroom-exhaust-fan-packaging-960x700.jpg.webp 960w, https:\/\/thetibble.com\/wp-content\/uploads\/2023\/07\/Bathroom-exhaust-fan-packaging-and-sones-level-man-checking-bathroom-exhaust-fan-packaging-150x109.jpg.webp 150w\" sizes=\"(max-width: 760px) calc(100vw - 24px), 720px\" data-pin-media=\"https:\/\/thetibble.com\/wp-content\/uploads\/2023\/07\/Bathroom-exhaust-fan-packaging-and-sones-level-man-checking-bathroom-exhaust-fan-packaging.jpg\" id=\"mv-trellis-img-3\" data-trellis-processed=\"1\"><\/figure>\n\n\n\n<p>Most people, including myself, are more familiar with sound being measured in decibels, so saying a fan is rated at 0.3 sones, does not mean much. <\/p>\n\n\n\n<p>However, if you use my <a href=\"https:\/\/thetibble.com\/sone-to-decibel-calculator\/\" data-lasso-id=\"68\">Sone to Decibel calculator<\/a>, you can see that 0.3 sones is about 22 decibels, and according to this <a rel=\"noopener\" href=\"https:\/\/audiology-web.s3.amazonaws.com\/migrated\/NoiseChart_Poster-%208.5x11.pdf_5399b289427535.32730330.pdf\" target=\"_blank\" data-lasso-id=\"69\">chart from The American Academy of Audiology<\/a>, rusling leaves are only about 20 decibels.

Then, you&rsquo;ll need to carefully clean out all the interior components. When ready, put the vent back on and test the fan. The noise should be gone.<\/strong><\/p>\n\n\n\n<p>If your fan has been making a suspicious noise, you should try cleaning it. Often, the fan can suck up dirt and debris, which ends up clogging the device.

However, if the dirt is lodged onto the vent, you might want to use a soft-bristled brush to get rid of it.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">3. Dry and Replace<\/h4>\n\n\n\n<p>Once all the dirt has been removed, you can leave it to air dry, on a towel. You shouldn&rsquo;t put it back in the fan until it&rsquo;s been completely dried. This will ensure that there&rsquo;s no chance that the vent will grow mold and bacteria.<\/p>\n\n\n\n<p>Turn on the power and the fan and see if that did the trick!<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Clean the Interior of the Bathroom Fan<\/h3>\n\n\n\n<p>When working on the interior of the fan, you need to make sure that you are being delicate. You don&rsquo;t want to accidentally damage any of the components.<\/p>\n\n\n\n<ol>\n<li>You&rsquo;ll need to turn off power to the bathroom. <\/li>\n\n\n\n<li>Use a vacuum to safely suck up all the dirt. Use the brush attachment as the thinner head will be able to fit into any nooks and crannies, sucking out as much dirt as possible.<\/li>\n\n\n\n<li>Use a microfiber cloth to remove any extra dirt and grime. Make sure that you are going through each part of the fan, trying to remove as much grime as possible.<\/li>\n<\/ol>\n\n\n\n<h4 class=\"wp-block-heading\">Disassembling the Fan for a Deeper Clean<\/h4>\n\n\n\n<p>In some cases, it might be best to disassemble the fan. This will allow you to remove all the built-up dirt. <\/p>\n\n\n\n<p>You can do this by unscrewing any exposed screws, carefully removing each of the components, and wiping with the microfiber cloth. <\/p>\n\n\n\n<p class=\"has-text-align-center has-background\" style=\"background-color:#e7d1b1\"><strong>Never clean the fan under running water!<\/strong><\/p>\n\n\n\n<p>When you have finished, you can re-assemble the fan. Then, place the vent cover back onto the fan by putting the metal clips back into their place and gently applying pressure to the vent.<\/p>\n\n\n\n<p>Finally, turn on the power and re-test the fan. Hopefully, the fan is now quiet!<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How Often Should I Clean My Bathroom Fan?<\/h3>\n\n\n\n<p><strong>Fan sucks up dirt and grime and so these will always be building up inside the fan. Because of this, it&rsquo;s recommended that you clean your bathroom fan every six months.<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-pullquote\"><blockquote><p><strong>It&rsquo;s recommended that you clean your bathroom fan every six months.<\/strong><\/p><\/blockquote><\/figure>\n\n\n\n<p>By cleaning your fan regularly, you will be able to prevent the debris from clogging the fan and making an unpleasant noise. It will also give you a chance to inspect the inside of the fan, so you will be able to spot which elements need to be replaced.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How To Tighten My Bathroom Fan?<\/h2>\n\n\n\n<p>One of the easiest problems to correct is a fan that is loose in the housing. <\/p>\n\n\n\n<p><strong>You simply take a screwdriver and tighten up all the screws. Be sure that the power is turned off before you do this!<\/strong><\/p>\n\n\n\n<p>But why are the screws loose? Well, as the fan spins, it can sometimes cause small vibrations. <strong>Over a long period, the vibrations can loosen the screws in the fan&rsquo;s housing. <\/strong><\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><noscript><img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"729\" src=\"https:\/\/thetibble.com\/wp-content\/uploads\/2023\/07\/Man-screwing-the-screws-on-the-bathroom-exhaust-fan.jpg\" alt=\"Man screwing the screws on the bathroom exhaust fan\" class=\"wp-image-34200\" srcset=\"https:\/\/thetibble.com\/wp-content\/uploads\/2023\/07\/Man-screwing-the-screws-on-the-bathroom-exhaust-fan.jpg 1000w, https:\/\/thetibble.com\/wp-content\/uploads\/2023\/07\/Man-screwing-the-screws-on-the-bathroom-exhaust-fan-300x219.jpg 300w, https:\/\/thetibble.com\/wp-content\/uploads\/2023\/07\/Man-screwing-the-screws-on-the-bathroom-exhaust-fan-768x560.jpg 768w, https:\/\/thetibble.com\/wp-content\/uploads\/2023\/07\/Man-screwing-the-screws-on-the-bathroom-exhaust-fan-960x700.jpg 960w, https:\/\/thetibble.com\/wp-content\/uploads\/2023\/07\/Man-screwing-the-screws-on-the-bathroom-exhaust-fan-150x109.jpg 150w\" sizes=\"(max-width: 760px) calc(100vw - 24px), 720px\"><\/noscript><img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"729\" src=\"https:\/\/thetibble.com\/wp-content\/uploads\/2023\/07\/Man-screwing-the-screws-on-the-bathroom-exhaust-fan.jpg.webp\" alt=\"Man screwing the screws on the bathroom exhaust fan\" class=\"wp-image-34200 lazyload\" srcset=\"https:\/\/thetibble.com\/wp-content\/uploads\/2023\/07\/Man-screwing-the-screws-on-the-bathroom-exhaust-fan.jpg.webp 1000w, https:\/\/thetibble.com\/wp-content\/uploads\/2023\/07\/Man-screwing-the-screws-on-the-bathroom-exhaust-fan-300x219.jpg.webp 300w, https:\/\/thetibble.com\/wp-content\/uploads\/2023\/07\/Man-screwing-the-screws-on-the-bathroom-exhaust-fan-768x560.jpg.webp 768w, https:\/\/thetibble.com\/wp-content\/uploads\/2023\/07\/Man-screwing-the-screws-on-the-bathroom-exhaust-fan-960x700.jpg.webp 960w, https:\/\/thetibble.com\/wp-content\/uploads\/2023\/07\/Man-screwing-the-screws-on-the-bathroom-exhaust-fan-150x109.jpg.webp 150w\" sizes=\"(max-width: 760px) calc(100vw - 24px), 720px\" data-pin-media=\"https:\/\/thetibble.com\/wp-content\/uploads\/2023\/07\/Man-screwing-the-screws-on-the-bathroom-exhaust-fan.jpg\" id=\"mv-trellis-img-6\" data-trellis-processed=\"1\"><\/figure>\n\n\n\n<p>As the screws become looser, the noise will become louder.<\/p>\n\n\n\n<p>In most cases, if your fan is making a rattling or vibrating noise, the screws will need to be tightened up. Thankfully, this is a fairly simple job.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How To Adjust My Bathroom Fan?<\/h2>\n\n\n\n<p>In some cases, your fan might be knocking against the housing. When this happens, you&rsquo;ll need to adjust the fan. <\/p>\n\n\n\n<p><strong>To adjust the fan, take off the vent cover. Then, check the housing around the fan. In some cases, you might need to unscrew the fan, place it in the right position, then screw everything back in.<\/strong><\/p>\n\n\n\n<p>Over time, it&rsquo;s normal for the fan to start to come out of its alignment. When this occurs, it can start knocking against the side of the housing. <\/p>\n\n\n\n<p class=\"has-text-align-center has-background\" style=\"background-color:#e7d1b1\"><strong>If not spotted and corrected early, this can lead to serious damage. In some cases, you might need to replace the fan entirely.<\/strong><\/p>\n\n\n\n<p>To correct the issue, you&rsquo;ll have to <strong>remove the vent cover<\/strong>. This will allow you to see the internal elements of the fan. We discussed how to do this earlier.<\/p>\n\n\n\n<p>Once inside, if possible, <strong>give the fan a spin; this will let you observe its current alignment.<\/strong> If it&rsquo;s knocking against the side of the housing, you will need to correct the problem.<\/p>\n\n\n\n<p>Before you do any more work, <strong>turn off the power to the bathroom.<\/strong> This will ensure that you don&rsquo;t accidentally electrocute yourself, or damage any of the internal components.<\/p>\n\n\n\n<p>You&rsquo;ll need to <strong>carefully remove the fan from the housing<\/strong>. Then, place it back inside, keeping everything straight. Gently tighten the screws, before pushing on the blades with your finger. If the fan doesn&rsquo;t hit the sides, tighten the screws up.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How To Lubricate My Bathroom Fan?<\/h2>\n\n\n\n<p>Another common reason why bathroom fans experience problems is that they haven&rsquo;t been lubricated properly. <\/p>\n\n\n\n<p><strong><meta charset=\"utf-8\"><strong>To lubricate your fan, you will need to first remove the vent cover and remove the fan from its housing.

The extra strain on the motor might make it louder. It might also cause the fan to produce a squeaking noise.<\/p>\n\n\n\n<p>Thankfully, it&rsquo;s fairly easy to lubricate the bathroom fan, as long as you follow the instructions below.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Preparing The Fan<\/h3>\n\n\n\n<p>Before you can apply the lubricant, you&rsquo;ll need to make sure that you&rsquo;ve prepared the fan properly. First, you will need to <strong>turn off the power to the bathroom<\/strong>. This will ensure that you don&rsquo;t accidentally electrocute yourself, or damage one of the internal components.<\/p>\n\n\n\n<p>Then, you&rsquo;ll be able to <strong>remove the vent from its housing<\/strong>. As we mentioned earlier, you&rsquo;ll often have to unscrew the vent, or gently squeeze it off its metal track.<\/p>\n\n\n\n<p>If you haven&rsquo;t already, make sure to <strong>clean your fan<\/strong> <strong>as described above<\/strong>. This will make sure that the lubrication works effectively.<\/p>\n\n\n\n<p>Finally, you will need to <strong>remove the fan<\/strong>. To do this, you&rsquo;ll need to unscrew the fan, removing it from the brackets that hold it in place.<\/p>\n\n\n\n<p><strong>When removing the fan, you&rsquo;ll also need to take out the wires; <\/strong><a href=\"https:\/\/thetibble.com\/are-bathroom-fans-hardwired\/\" data-lasso-id=\"75\">m<\/a><a href=\"https:\/\/thetibble.com\/are-bathroom-fans-hardwired\/\" data-lasso-id=\"76\">ost bathroom fans are hardwired<\/a>. When replacing only the motor, you could be lucky and there could be a plug that will make your life much easier.<\/p>\n\n\n\n<p>When it is hardwired, you might want to <strong>take a few pictures<\/strong>. This will let you make sure that you put them back in the right place.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How To Apply Lubrication To The Fan?<\/h3>\n\n\n\n<p><strong>First, you need to find the shaft of the fan. <\/strong>This is the part of the fan that connects the spinning blades to the motor.<strong> <\/strong><\/p>\n\n\n\n<p><strong>Then, rub the lubricant onto the shaft and give it a few spins, to make sure that it&rsquo;s working properly.<\/strong> There are many types of lubricants that you might want to use.

By doing this, you should be able to greatly reduce the amount of noise that the bathroom fan is making.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How Can I Insulate My Bathroom Fan?<\/h3>\n\n\n\n<p><strong>To insulate your fan, place a thin strip of sound-absorbing rubber along the top of the unit, where the fan meets the ceiling. <\/strong>This will reduce the sound vibrations and should make the unit quieter.<\/p>\n\n\n\n<p>When the bathroom fan is working, it produces small vibrations. This could be why it&rsquo;s so loud when you turn it on. Placing rubber along the top of the unit will help absorb these vibrations, making it quieter.<\/p>\n\n\n\n<p>To do this:<\/p>\n\n\n\n<ol>\n<li><strong>Purchase some thin, sound-absorbing rubber<\/strong>. You should be able to find this in most hardware stores.<\/li>\n\n\n\n<li><strong>Turn off the power to the bathroom<\/strong>, so you don&rsquo;t accidentally hurt yourself.<\/li>\n\n\n\n<li><strong>Remove the bathroom fan unit from the ceiling<\/strong>. In most cases, you should be able to do this with a screwdriver. However, if you&rsquo;ve chosen a big unit, you might want to get a friend over to help you lift it from the ceiling. <\/li>\n\n\n\n<li>If you need to undo any wires, take a picture, so you know where to connect them later.<\/li>\n\n\n\n<li>Measure and cut the rubber. <\/li>\n\n\n\n<li>Place this between the drywall and the fan housing. You should be able to <strong>stick the rubber to the ceiling with some glue, to hold it in place<\/strong>. <\/li>\n\n\n\n<li>Reattach the fan unit.<\/li>\n<\/ol>\n\n\n\n<h3 class=\"wp-block-heading\">Why Should I Make My Bathroom Duct Shorter?<\/h3>\n\n\n\n<p><strong>The longer your bathroom duct, the more air pressure the fan will need to exert to remove the air from the room. This also occurs if you have a lot of twists and bends in the duct. Because of this, it will place more strain on the motor, causing it to make a louder noise.<\/strong><\/p>\n\n\n<div class=\"wp-block-image size-large\">\n<figure class=\"aligncenter is-resized\"><noscript><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/thetibble.com\/wp-content\/uploads\/2020\/05\/Why-Should-I-Make-My-Bathroom-Duct-Shorter-1024x683.jpg\" alt=\"\" class=\"wp-image-173\" width=\"343\" height=\"228\" srcset=\"https:\/\/thetibble.com\/wp-content\/uploads\/2020\/05\/Why-Should-I-Make-My-Bathroom-Duct-Shorter-1024x683.jpg 1024w, https:\/\/thetibble.com\/wp-content\/uploads\/2020\/05\/Why-Should-I-Make-My-Bathroom-Duct-Shorter-300x200.jpg 300w, https:\/\/thetibble.com\/wp-content\/uploads\/2020\/05\/Why-Should-I-Make-My-Bathroom-Duct-Shorter-768x512.jpg 768w, https:\/\/thetibble.com\/wp-content\/uploads\/2020\/05\/Why-Should-I-Make-My-Bathroom-Duct-Shorter.jpg 1200w\" sizes=\"(max-width: 760px) calc(100vw - 24px), 720px\"><\/noscript><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/thetibble.com\/wp-content\/uploads\/2020\/05\/Why-Should-I-Make-My-Bathroom-Duct-Shorter-1024x683.jpg.webp\" alt=\"\" class=\"wp-image-173 lazyload\" width=\"343\" height=\"228\" srcset=\"https:\/\/thetibble.com\/wp-content\/uploads\/2020\/05\/Why-Should-I-Make-My-Bathroom-Duct-Shorter-1024x683.jpg.webp 1024w, https:\/\/thetibble.com\/wp-content\/uploads\/2020\/05\/Why-Should-I-Make-My-Bathroom-Duct-Shorter-300x200.jpg.webp 300w, https:\/\/thetibble.com\/wp-content\/uploads\/2020\/05\/Why-Should-I-Make-My-Bathroom-Duct-Shorter-768x512.jpg.webp 768w, https:\/\/thetibble.com\/wp-content\/uploads\/2020\/05\/Why-Should-I-Make-My-Bathroom-Duct-Shorter.jpg.webp 1200w\" sizes=\"(max-width: 760px) calc(100vw - 24px), 720px\" data-pin-media=\"https:\/\/thetibble.com\/wp-content\/uploads\/2020\/05\/Why-Should-I-Make-My-Bathroom-Duct-Shorter.jpg\" id=\"mv-trellis-img-10\" data-trellis-processed=\"1\"><\/figure><\/div>\n\n\n<p>Though this often isn&rsquo;t the primary reason why your bathroom fan is so noisy, it can be a contributing factor.
