Splashing through puddles is an activity that should be strictly limited to the outdoors. If you are looking to avoid this, you might be considering installing a condensation trap with your bathroom fan.<\/p>\n\n\n\n<p>But it&rsquo;s an extra cost of both money and time and begs the question: do you really need one? The only reason to install a condensation trap is if your fan will drip. Great, so how do you know that? Thankfully, you can take steps during installation that will help prevent dripping and, thus, the need for a trap.<\/p>\n\n\n<div class=\"lazyblock-nutshell-Z1kuwIy wp-block-lazyblock-nutshell\"><p class=\"has-text-align-left has-text-color has-background\" style=\"background-color:#e7d1b1;color:#575f60;font-size:18px\"><noscript><img loading=\"lazy\" decoding=\"async\" width=\"200\" height=\"50\" class=\"wp-image-3497\" style=\"width: 200px;\" src=\"https:\/\/thetibble.com\/wp-content\/uploads\/2021\/08\/nutshell1-11.png\" alt=\"\" srcset=\"https:\/\/thetibble.com\/wp-content\/uploads\/2021\/08\/nutshell1-11.png 600w, https:\/\/thetibble.com\/wp-content\/uploads\/2021\/08\/nutshell1-11-300x75.png 300w\" sizes=\"(max-width: 200px) 100vw, 200px\"><\/noscript><img loading=\"eager\" decoding=\"async\" width=\"200\" height=\"50\" class=\"wp-image-3497 eager-load\" style=\"width: 200px;\" src=\"data:image\/svg+xml,%3Csvg%20xmlns='http:\/\/www.w3.org\/2000\/svg'%20viewBox='0%200%20200%2050'%3E%3Crect%20width='200'%20height='50'%20style='fill:%23e3e3e3'\/%3E%3C\/svg%3E\" alt=\"\" sizes=\"(max-width: 200px) 100vw, 200px\" data-pin-media=\"https:\/\/thetibble.com\/wp-content\/uploads\/2021\/08\/nutshell1-11.png\" id=\"mv-trellis-img-1\" data-src=\"https:\/\/thetibble.com\/wp-content\/uploads\/2021\/08\/nutshell1-11.png.webp\" data-srcset=\"https:\/\/thetibble.com\/wp-content\/uploads\/2021\/08\/nutshell1-11.png.webp 600w, https:\/\/thetibble.com\/wp-content\/uploads\/2021\/08\/nutshell1-11-300x75.png.webp 300w\" data-svg=\"1\" data-trellis-processed=\"1\"><br><strong>The common reason bathroom fans drip is due to condensation forming in the ducts.

Moreover, rust can form on the fan, and the dampness can also lead to mold and mildew growing in the ducts and around the fan and seals.<\/p>\n\n\n<div class=\"wp-block-image is-style-rounded\">\n<figure class=\"aligncenter size-large\"><noscript><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"512\" src=\"https:\/\/thetibble.com\/wp-content\/uploads\/2021\/04\/bathroom-fan-one-1024x512.jpg\" alt=\"Bath fan surrounded by black and white butterflies\" class=\"wp-image-1645\"><\/noscript><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"512\" src=\"https:\/\/thetibble.com\/wp-content\/uploads\/2021\/04\/bathroom-fan-one-1024x512.jpg.webp\" alt=\"Bath fan surrounded by black and white butterflies\" class=\"wp-image-1645 lazyload\" data-pin-media=\"https:\/\/thetibble.com\/wp-content\/uploads\/2021\/04\/bathroom-fan-one-e1640252599303.jpg\" id=\"mv-trellis-img-3\" data-trellis-processed=\"1\"><\/figure><\/div>\n\n\n<p>The water that forms on the floor can be a slipping hazard, especially for the oldest and youngest generations. So, it is very important not to have puddles standing in your bathroom for safety reasons. &nbsp;<\/p>\n\n\n\n<p>Dirt and rust dripping into your bathroom will also cause staining. Dirty marks in your bathroom are unsightly and unwelcome, and as it is a recurring problem, your cleaning and repainting might feel futile after a while.<\/p>\n\n\n\n<p>Mold and mildew are health hazards, and we all want to avoid them. Aside from the well-being of your household, mold and mildew can further compromise your bathroom fan if they grow on and damage the fan and seals in the ducting.<\/p>\n\n\n\n<p>If your fan movement is compromised by building fungi, the condensation problem will worsen as air is exhausted less efficiently. The seals on your backdraft damper are necessary for airtightness in order to prevent the exhausted air from flowing back into the bathroom.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"why-do-bathroom-fans-drip\">Why Do Bathroom Fans Drip?<\/h2>\n\n\n\n<p>Your <a href=\"https:\/\/thetibble.com\/bathroom-fan-dripping\/\">bathroom fan might be dripping for a variety of reasons<\/a>, the most common being due to condensation. <\/p>\n\n\n\n<p><strong>Condensation is the product of the meeting of air of different temperatures. This would cause your fan to drip.<\/strong><\/p>\n\n\n\n<p>The bathroom air is generally hot and humid after a shower, and the reason that the air is humid is because warmer air can hold more moisture than colder air. Condensation occurs when this hot air, in contact with colder air from outside, cools and can no longer hold as much water.<\/p>\n\n\n\n<p class=\"has-text-align-center\">\n    <a data-amazonimages=\"\" target=\"_blank\" title=\"by.RHO Condensation Drip Absorbent Tape Self Adhesive Moisture Trap 9.8' Blue\" href=\"https:\/\/www.amazon.com\/dp\/B01MY6W3AA?tag=hvacbuzz-20\" rel=\"nofollow noopener\"><noscript><img decoding=\"async\" class=\"size-large aligncenter\" src=\"https:\/\/m.media-amazon.com\/images\/I\/51-tHH6vmiL._SL500_.jpg\" alt=\"by.RHO Condensation Drip Absorbent Tape Self Adhesive Moisture Trap 9.8' Blue\" title=\"by.RHO Condensation Drip Absorbent Tape Self Adhesive Moisture Trap 9.8' Blue\"><\/noscript><img decoding=\"async\" class=\"size-large aligncenter lazyload\" src=\"https:\/\/m.media-amazon.com\/images\/I\/51-tHH6vmiL._SL500_.jpg\" alt=\"by.RHO Condensation Drip Absorbent Tape Self Adhesive Moisture Trap 9.8' Blue\" title=\"by.RHO Condensation Drip Absorbent Tape Self Adhesive Moisture Trap 9.8' Blue\" data-mvt-skip=\"src\" loading=\"lazy\" data-trellis-processed=\"1\"><\/a>\n<\/p>\n\n\n\n<p>When the air cannot hold as much water, it forms droplets or condensation in the ducts, and this drips out of your bathroom fan.<\/p>\n\n\n\n<p>This can also occur in tropical environments where the bathroom air is potentially the cooler party and the outside air is hot. The meeting will still produce condensation.<\/p>\n\n\n\n<p>There are several reasons why condensation can form, and there are some pre-emptive actions you can take against the possibility.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"fans-less-likely-to-need-condensation-trap-if\">Fans Less Likely to Need Condensation Trap If&hellip;<\/h2>\n\n\n\n<p>Dripping fans are common, but this <a href=\"https:\/\/thetibble.com\/normal-bathroom-fan-drip\/\">doesn&rsquo;t mean that they are normal<\/a>. <\/p>\n\n\n\n<p>I believe that a condensation trap is unnecessary if the duct is appropriately and properly insulated, is not excessively long, and if there is a quality, airtight damper installed in the duct. <\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"insulation\">Insulation<\/h3>\n\n\n\n<p>When you <a href=\"https:\/\/thetibble.com\/should-exhaust-duct-be-insulated\/\">insulate the duct<\/a>, you prevent the hot and cold air from meeting, which allows the extractor to exhaust the hot air from the bathroom. This, in turn, prevents condensation from forming, so your bathroom fan can stay dry and drip-free. This might even involve replacing old insulation that is no longer functioning appropriately.<\/p>\n\n\n\n<p class=\"has-text-align-center\">\n    <a data-amazonimages=\"\" target=\"_blank\" title=\"Dundas Jafine BPC425R6 Insulated Flexible Duct with Black Jacket, 4-Inches by 25-Feet\" href=\"https:\/\/www.amazon.com\/dp\/B0049H9970?tag=hvacbuzz-20\" rel=\"nofollow noopener\"><noscript><img decoding=\"async\" class=\"size-large aligncenter\" src=\"https:\/\/m.media-amazon.com\/images\/I\/41205wzOoaS._SL500_.jpg\" alt=\"Dundas Jafine BPC425R6 Insulated Flexible Duct with Black Jacket, 4-Inches by 25-Feet\" title=\"Dundas Jafine BPC425R6 Insulated Flexible Duct with Black Jacket, 4-Inches by 25-Feet\"><\/noscript><img decoding=\"async\" class=\"size-large aligncenter lazyload\" src=\"https:\/\/m.media-amazon.com\/images\/I\/41205wzOoaS._SL500_.jpg\" alt=\"Dundas Jafine BPC425R6 Insulated Flexible Duct with Black Jacket, 4-Inches by 25-Feet\" title=\"Dundas Jafine BPC425R6 Insulated Flexible Duct with Black Jacket, 4-Inches by 25-Feet\" data-mvt-skip=\"src\" loading=\"lazy\" data-trellis-processed=\"1\"><\/a>\n<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"duct-length\">Duct Length<\/h3>\n\n\n\n<p><a href=\"https:\/\/thetibble.com\/bath-fan-duct-length-dimension-table\/\">Shorter ducts are more efficient<\/a> because they can maintain the air pressure better. So, if your duct is shorter, it creates a more effective environment for the exhaust system to remove the air and moisture from the bathroom.<\/p>\n\n\n\n<p>The more efficient your bathroom fan can be, the faster it can exhaust hot air, and this means there is less opportunity for condensation to form.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"damper\">Damper<\/h3>\n\n\n\n<p>A backdraft damper is a necessary accessory for your bathroom fan, and a quality product with a good seal will help ensure your fan won&rsquo;t drip. Backdraft dampers are designed to prevent the backflow of exhausted air.<\/p>\n\n\n\n<p>With an airtight damper, hot air from the bathroom will be allowed into the ducts, but no air will be allowed to enter the bathroom via the same route. This prevents hot and cold air from mixing in your bathroom ducting, which allows the exhaust system to function effectively without condensation at the fan.<\/p>\n\n\n<div class=\"lazyblock-amazonblock-W8MrA wp-block-lazyblock-amazonblock\">\n<div class=\"aawp\">\n\n            \n            \n<div class=\"aawp-product aawp-product--horizontal aawp-product--css-adjust-image-large\" data-aawp-product-asin=\"B0842XSTV9\" data-aawp-product-id=\"8032\" data-aawp-tracking-id=\"hvacbuzz-20\" data-aawp-product-title=\"AC Infinity 4  Backdraft Damper One-Way Airflow Ducting Insert with Spring-Loaded Folding Blades for 4&rdquo;
