A ventless bathroom fan is the answer to your humidity problem if installing a wall or ceiling ducted model is not a practical option. For example, if you have a bathroom in the basement or if you live in a rental home that does not currently have a fan, why should you have to deal with the odor and the mold that is associated with all of that extra moisture from your shower? It is fair to say that no bathroom should be without some type of fan.
With these types of fans, you do not have to worry about cutting any holes or fitting into walls. Ductless systems require no outside vent and can be installed either on the wall or the ceiling. They feature 12v motors that are traditionally removable so that they can be easily cleaned.
You will also find that installation is a breeze with these units as they usually have tension spring mounting. Not to mention, they often weigh less than five pounds.
Why You Need One
While you may be able to live without a bathroom heater fan, you still need some type of unit in there to help with humidity. When you take a shower, you create steam which leaves you with an abundance of moisture left in the air. Where exactly do you think all of that water goes? It actually has no place to go besides to be absorbed by your wood molding, cabinets, cloth shower curtains, rugs, towels, decorative items or any other absorbent material that you have in the room.
Moisture that lingers in a bathroom that has no ventilation promote the growth of mildew and mold and you should know that these are living, growing organisms. Additionally, moisture from your shower creates another serious problem with your wood in the room being that it rots it which will cause a larger home improvement project in the long run when you have to start replacing moldings, etc. Not to mention, the smell of mold as it continues to get moist and grow over time is anything but pleasant.
Whenever possible, your goal is to install an extractor fan that is manufactured by a trusted company such as Greenwood, Silavent or Xpelair that comply with all building regulations. However, if you absolutely cannot add the duct work to your bathroom, a ventless bathroom fan is your next best option.
