Do you know how to ventilate a room without windows? If not, don’t worry. I am going to tell you 14 effective and convenient methods of air ventilation. So, let’s dive deep into the process right now!
A Quick Overview
Proper ventilation is a must for any room, be it with a window or windowless. Because poor ventilation can lead up to many problems, such as:
- Toxic pollutants in the air
- Breathing problems for asthma people
- Long-term lung diseases
So reducing stale air and increasing fresh airflow is in your interest. For better ventilation, we can use various fans, indoor plants, and even AC and cooler units in windowless rooms.
Now let me unravel more useful methods of ventilation!
Ventilating Rooms Without Windows: 14 Great Ways of Air Circulation
A windowless room doesn’t have the capacity to circulate air. However, I found some useful methods of bringing fresh air into a room. Let’s explore these tips.
1. Keep the Door Open for Fresh Air
The easiest way to get some healthy breeze in windowless rooms is to keep the door open. It doesn’t cost any money, and you can do it any time of the day. This is a natural ventilation system that expels hot air.
However, there are two problems with this method:
- Dust might enter with the airflow.
- Pets might intrude into the space.
To avoid these problems, you should grab the other options.
2. Outside Wall Mechanical Ventilation
It is a popular method to install hooded vent fans on the outside wall:
- This fan reduces humid air and brings fresh air into the room.
- Removing smoke and fumes is highly useful for the kitchen room.
3. Using Portable or Ceiling Fans
Fans can be a good option for ventilating fresh air.
- A ceiling fan provides significant air ventilation for closed areas.
- Using a ceiling fan can improve air circulation by a significant amount.
- It might not be a highly effective ventilation system for a room without windows.
- But it can bring considerable airflow in smaller rooms.
- Portable fans are more effective for windowless rooms.
- The placement of the fan is important because a portable fan next to the door will bring refreshing air and distribute it into the room.
- Unfortunately, it cannot cover a big space.
4. Using an Air Conditioning System
An air conditioner is a great way to reduce heat. But do you know it can increase air circulation to a substantial level? An air conditioner draws all the hot air and then releases fresh and cool air into the surrounding:
- This way, air conditioners cool the temperature and improve air quality.
- Portable air conditioners are suitable if you live in a rented house.
- However, the air conditioning system is expensive a bit.
- You need to clean the filter regularly.
5. Installing an Extractor Fan
We all know the effectiveness of an extractor fan, don’t we? It is a common method of ventilating a windowless room. These fans are most suitable for installation in bathrooms, kitchens, and small spaces.
An effective extractor fan removes humid air from settling and prevents steam, fumes, and odors. You can install any of these three extractor fans.
- Mixed or Inline
6. Passive Outside Venting
Another effective ventilation system is using passive vents through walls:
- Vent tubes can carry the stuck stale air from your windowless room and keep the circulation process ongoing.
- Most air conditioning systems today come with flexible vents.
So it is a good option for proper ventilation.
7. Using Porous Materials
For better wind flow, porous materials can be of great use:
- These materials contain minute spaces through which air (and even liquid) can pass.
- There are some special air bricks widely used as porous materials.
You should try them out!
8. Minimizing Room Furniture
You probably won’t get enough clean air if your living space is crowded with furniture. The furniture prevents circulating air and makes the environment musty.
Believe me or not, it is one of the best handy ventilation strategies to supply abundant fresh air!
9. Indoor Plants to Remove Stale Air
All people are not capable of affording air conditioners, do they? So we need a cheap and easy strategy to ventilate a room without windows.
In such a scenario, air-purifying plants come handy. These plants are useful in removing stale air and releasing fresh oxygen.
Air-purifying plants are also aesthetic to look at. Here are some of the best indoor plants of my choice.
- Aloe Vera
- Boston ferns
- Spider Plant
- Golden pathos
- Money Plant
- Chrysanthemum or chrysanths
- Areca palms
- Dragon Tree
10. Air Bricks Installation
Believe me or not, air bricks installation is an excellent strategy for natural ventilation for a windowless room. An air brick has certain holes to pass air flow and keep pushing cold air inside.
You need to remove a convenient section of the wall and then place air bricks there. But remember, these hidden air bricks are prone to dust accumulation.
11. Utilizing Air Purifier/Dehumidifier
This is a common phenomenon that an air purifier can filter all sorts of dust and provide healthy breathing space. If you install one of them, a windowless room will get enough circulated air.
Moreover, a dehumidifier is also a good option for removing excess moisture. It prevents dampness and mold growth to a great extent.
12. Installing Ductless Air Conditioning System
I’m sure many of you have heard about the ductless air conditioning system:
- It is a relatively easy and affordable way to get much fresh air.
- You need to connect the internal and external units through the wall.
- The filter will draw the necessary air and then pump it inside.
- It is perhaps the finest method to get much colder air in a windowless room.
13. Using A Portable Evaporative Cooler
Air coolers are an optimal option to remove hot air:
- It is a device where you put water or ice and get cold air in return.
- Though the main purpose of this device is to cool the room, it is highly effective in ventilation.
But these coolers are expensive, though.
14. Airflow From The Adjacent Room
It might sound a bit odd to borrow air from the adjoining room, but it truly works. If your room has a ventilated adjacent room, you can install:
- Some louvered doors,
- Slide doors, or even
- An air grille.
This will help your room to cool down and circulate a good chunk of wind.
Why is Room Ventilation of Great Value?
There are several significant reasons for installing a ventilation system in your house. But here I’m giving a list of reasons I found solid.
1. Removing Dampness
When you cannot ventilate a windowless room, the room will be fraught with dampness and mold spores. As a consequence, you can have respiratory problems.
If there is any proper ventilation in the room, it will be healthy to breathe there without facing any musty smell and unwanted dust.
2. Radon Gas Elimination
Radon is a rare radioactive gas usually found in granite. The horrible thing is radon is an airborne gas that can settle in your lung causing lung cancer.
A properly ventilated room would reduce the chance of radon infection.
3. Healthy Environment
You might get shocked to hear that a restricted area without air circulation brings a lot of health issues. Rooms without ventilation remain humid all the time. And breathing in humid, damp air brings forth eczema and asthma.
4. VOC Minimization
A room without windows accumulates various volatile organic compounds or VOCs. This accumulation can be the direct result of restricted airflow and zero ventilation.
These VOCs cause some serious health problems. Air circulation and ventilation would remove any chance of VOC accumulation.
5. Fever and Allergy Reduction
We often see people with hay fever and allergies. One of the latent causes of these diseases is having no airflow. Good ventilation would remove any pollen and dust from the room and ensure fresh, healthy air.
Frequently Asked Questions
How do you ventilate a closed room?
Using an air conditioner or a ceiling fan can easily ventilate a closed room. Moreover, installing an exhaust fan into the HVAC system is also a good option.
How do you ventilate a room naturally?
You have to keep the windows and doors open to let in the breeze. Though with little effect, the indoor plant is a good way to ventilate closed areas.
What happens if a room has no ventilation?
CO2, Radon gas, and mold can be present in a room without ventilation. All these lead to respiratory problems, allergic reactions, and whatnot.
What to do if your room has no windows?
You can use fans, passive vents, and dehumidifiers and grow indoor plants if your room has no windows.
If good health is your first priority, you must focus on the ventilation system. Use one or two effective methods I have given to yield optimal results. Don’t forget to ask for a professional’s help when you are stuck.
