Best Ways To Ventilate A Bathroom Without Windows
Let’s take a look at the different ventilation solutions you can consider to improve the air circulation in your window-less bathroom.
1. Use An Exhaust Fan
The best solution is to get an exhaust fan installed in your washroom.
An exhaust fan will be worth the investment if proper ventilation is your priority.
The m
echanical process of an exhaust fan is designed to eliminate the air in the washroom and bring back clean air.It also dries up dampness and improves air circulation.
Turning on the exhaust fan for 15 to 20 minutes after you shower or use the toilet is best.
This
would be sufficient to pull any humid, stale, or contaminated air from the washroom.One tip for buying an exhaust fan is to check its size first. It should be big enough to work effectively in your bathroom.
So, if your bathroom has a measurement of 100 square feet, your exhaust fan should be rated for 100 CFM.

- It Covers 215 sq ft
- Lightweight, Compact and Portable
- Auto Shut-Off
- Capable of removing up to 9 ounces of water per day
- Perfect for high humidity in your home, kitchen, bathroom, bedroom, garage, closet
Another good source of ventilation can be a dehumidifier.
You c
an use this appliance to prevent excess moisture build-up if you have a steamy washroom and no window or exhaust fan.A dehumidifier works by sucking out the humid air and blowing dry air inside. In simple words, it dehumidifies the room and keeps the air fresh.
Mostly, dehumidifiers are more effective for smaller bathrooms.
They
tend to be expensive, especially if you need one for a large-sized bathroom.However, you must know that a regular dehumidifier won’t do the trick or provide proper ventilation.
A regular dehumidifier releases the same air rather than replacing it with fresh air. And it does not cycle the air out of the bathroom.
You wou
ld need a commercial-grade humidifier or have them installed into the HVAC system throughout the house3. Install A Ceiling Fan
Ventilating a bathroom is also possible through a ceiling fan. This does not work like a dehumidifier or exhaust fan in drawing out moisture.
However, if you use it correctly, it can surely help ventilate the room.
Remembe
r, a ceiling fan should move air from another well-ventilated room into the bathroom. So, it would help if you opened the bathroom door when the ceiling fan was running to make this work.Why is this important?
If you keep the bathroom closed, the same moist, warm air will move around in the same space.
Similar
ly, if the air is coming in from an unventilated room, then fresh air won’t enter inside. This can result in moisture and mold-related problems in the bathroom.4. Use An Air purifier

An air purifier removes pollutants, toxins, and allergens from the air. It sanitizes the air you breathe by trapping these particles with the help of a filter.
Sometimes, it also has a fan that sucks in the air, passing through the filters.
This keep
s the air circulation healthy and fresh indoors. In a windowless bathroom, air purifiers can be beneficial in providing better air quality.They can also remove foul odors and improve the ventilation of the room.
You can look for air purifiers specially designed for bathrooms. These can be mounted and have filtration systems to keep foul odors and mold at bay without using chemicals.
