FAQ

Those who are looking for an answer to the question «Why is my bathroom fan not removing moisture?» often ask the following questions:

❔ Is there a no duct moisture removing bathroom fan?

A duct fan is where you vent the air outside the bathroom through a ventilation pipe. A ductless fan is that kind of fan installed in the bathroom and doesn’t have ventilation pipes. It removes moisture and odor from the bath. It works with an activated charcoal filter that works within the bathroom.

❔ Bathroom moisture problems?

❔ Do bathroom fans remove moisture?

The primary purpose for having an exhaust fan is to remove the moisture out of the bathroom. These fans help to control and eliminate bathroom odors. Additionally, they add to the safety of the home and its residents by reducing fumes from cleaning agents that could potentially cause health-related issues.

The fan is not a magical device which removes all moisture instantly, and you may need to understand this and do things differently ( in other parts of the property) to deal with condensation issues. If the fan really is not effective, then you need to look at the length of any duct, bends or other choke points in the duct or outlet, and type of fan.

A fan will expel air, but only when there is makeup air to replace it. Make sure there is a sufficient gap under the bathroom door. (An easy way to test this issue is to run the fan with and without the door open and see if there is a difference) as others have stated, make sure the fan is clean.

If you find filters when you remove the grille, you have a recirculating fan. Sometimes the problem isn’t with the exhaust fan, but rather other factors in the bathroom are causing the problem. A fan that’s too small for a room won’t be efficient in removing moisture. A lack of air coming into the room can lead to problems as well.

You can’t expect prolonged exposure to a room full of steam not to condense on your bathroom walls, so start by cutting back on the length of your shower and lower the water temperature. A bathroom vent fan isn’t designed to remove all steam in a matter of seconds; so you have a confined space that’s filling with steam faster than one, or even two, fans can pump it out.

The moisture is slowly removed by turning the air over a few times, and a properly sized fan will exchange the air in a bathroom about four times per hour. You want the fan to be running during, and at least 15 minutes after the shower, but if you still have mold forming in the shower you need to go to 30 minutes and keep increasing as necessary.

The bathroom is too airtight A fan can only drive air out of the bathroom if replacement air can get into the bathroom. Without adequate replacement air, the fan may not be able to warm up the duct and completely evacuate the moisture. The easiest way to let in replacement air is to leave the door cracked open while the fan is running.

Here are 5 reasons why this happens. 1. No duct, fan blowing into insulation. As you can see in the photo above, there’s no duct attached to this fan. Usually, no duct means better air flow. The air doesn’t go where you’d like it to, but it flows easily. Except when it doesn’t, of course, as in in this case.

The moral of the story here — if you suspect the fan in your bathroom only sounds like it is working, it might be worth checking (or having a professional check) the exhaust vent. If the damper does not move freely, or there is an obstruction in the ductwork, your bath fan may not be able to do its job.

A recirculating bath fan would be a workable option for a half-bath because there’s no shower to fill the space with moisture. Reduce noise with an inline fan. As a duct run gets longer or includes more elbows for changing direction, it takes more blowing power to exhaust air to the exterior. More powerful fans also tend to produce more noise.

This fan can turn on automatically when relative humidity surpasses a certain level, usually 60% (if you can set it below that, it will be even better against mold). Many are quite versatile, allowing you to adjust both the CFM and humidity level threshold at which the fan should turn on.
