How to improve air circulation in a room without windows

Most of the time rooms such as basements, attics, storage spaces or even rooms are constructed without windows. This leads to poor air flow and bad air quality. However this does not mean that you cannot improve the air quality of your room.

Here in this article we will give you some insights about the importance of ventilation, health effects related to poor ventilation and also how you can provide more air circulation within these areas. 

How to improve air circulation in a room without windows 

We can improve the air circulation in a room without windows by the following means: 

  • Create ventilation using  portable and ceiling fans
  • Use of evaporative coolers and whole house fans
  • Turn on the HVAC system 
  • Add an air conditioning system
  • Use a dehumidifier or an air purifier
  • Simply open the doors and windows
  • Introduce plants that purifies air
  • Reduce the amount of furniture in a windowless room
  • Use of porous building material
  • Use scented candles

What is the importance of ventilation?

Ventilation is very important for a healthy, disease free, fresh smelling home.

The following are some of the reasons why ventilation is so important:

Ventilation removes condensation 

Condensation leads to moisture build up and dampness in the house, which becomes a breeding ground for mold growth. Mold growth is characterized by  damp patches on the walls, paper peeling, musty odors and several health problems like; allergic rhinitis, asthma and allergic conjunctivitis, fatigue, nausea, and secondary bacterial infections such as sinusitis. 

 

Ventilation is vital for healthier living environment

Excessive dampness due to poor ventilation leads to certain health related issues like asthma attacks, skin problems like redness, itchy skin, eczema, chronic sneezing etc.

 

Ventilation keeps hay fever at bay

A well ventilated house is considered disease free as it filters  the airborne  allergens such as pollen out of your house. Thus reducing the chances of catching seasonal hay fever. 

Ventilation reduces the effect of radon gas

Radon is a naturally occurring gas found in the soil. It can enter the houses through cracks and crevices. Exposure to this harmful gas can cause lung cancer.

A proper ventilation system reduces the level of radon exposure.

 

Ventilation reduces the exposure of harmful VOCs such as benzene, acrolein,  benzo(a)pyrene

Common sources of Volatile Organic Compounds (VOCs) include paints, solvents, wood preservatives, aerosol sprays, household cleansers and disinfectants, air fresheners, stored fuels, etc. 

VOCs are known to cause symptoms like; eye, nose and throat irritation, shortness of breath, headaches, fatigue, nausea,dizziness and many skin problems. Some VOCs are suspected to cause cancer such as Benzene. It is a known human carcinogen.

Proper ventilation allows fresh air into the house and dilutes the effects of VOCs. 

Ways to improve  improve air circulation in a room without windows

There’s no need to worry if you have a windowless room. We will give you some tips to increase airflow in your room, so try the following strategies to get a freshly smelling, clean, and habitable room. 

Create ventilation using  portable and ceiling fans.

If opening windows are not feasible consider using bathroom and stove exhaust fans. Try placing the fans close to an open window or a door.

This ensures better air circulation and draws the air borne particles like viruses, bacteria and particulates out of your house.

An exhaust fan works in a reverse motion. It blows air outward and draws fresh air and moisture inwards. This removes contaminants and allows moisture into your house. 

Ceiling fans are also efficient at proper air circulation even if the windows are closed. Use of ceiling fans is a relatively energy efficient, and cost effective way to enhance the airflow of your house. 

You can find the links to some of the fans in the links below:

Use of evaporative coolers and whole house fans

Evaporative coolers are also known as swamp coolers. They help in increasing the ventilation in the room and also cools down the indoor air. Evaporative coolers are ideal for dry climates. They require water to provide cooling and also enhances the relative humidity of the room.

The whole house fans provide cooling by pulling the outside air through the open windows and doors. The use of whole house fans should be avoided if the air pollution is high outside.

You can find the links to some evaporative coolers and whole house fans in the links below:

Turn on the HVAC system 

The HVAC system works efficiently towards filtering airborne contaminants. If you have a central heating, ventilation and air conditioning system (HVAC) at home, set the fan to the “on” position rather than auto, especially when you have visitors. This helps in continuous circulation of air. The filter should be upgraded on a timely basis in order to maintain its efficiency.

Below are the best HVAC systems for improving the air flow in your room:

HVAC Systems Why i recommend it 
Honeywell F300E1019 Electronic Air Cleaner



This can be operated with gas, oil and AC systems. Efficiency for capturing particles is upto 98%.Has a very low pressure drop

Add an air conditioning system

Apart from cooling, the air conditioners also help in ventilation by the circulation of air inside the room.The air conditioner works on a principle that it draws the warm air of the room and replaces it with cool air, thus ensuring proper air circulation. Air conditioners also help in keeping the dampness at bay.

You can find the links to some air conditioners in the links below:

Air conditioners Why i recommend it

Use a dehumidifier 

Dehumidifiers help extract the excessive moisture out of your room. Dehumidifier works on a two step principle:Firstly it draws moisture out of the air and collects the water on a drip tray Secondly it warms up the collected dry and cold air and finally fan the dry air back in the room. 

Below are the some of the best dehumidifiers for improving the air flow in your room:

Use air cleaners and purifiers

The simplest way to improve basement air quality is to install air purifiers. Air purifiers are devices which circulate the air through a set of filters and capture the contaminants like; microscopic particles such as dust, allergens, molds, spores, bacteria, etc, that are floating around.

If you do not have an HVAC system then you can also use high efficiency particulate air or HEPA cleaner. They work efficiently against air borne particles

Nowadays there are many filters available in markets having several features like HEPA filter, Activated carbon filter, and ultraviolet light. 

Below are the best air purifiers for improving the air flow in your room:
