Air purifiers normally take around 12 hours to clean a room as they circulate the air for a few minutes at a time. It is important to note that these times can vary depending on the size of your room and the effectiveness of your purifier.

Factors Affecting the Cleaning Mechanism of an Air Purifier

1. Power Setting 


The power setting on an air purifier controls the time it takes for the purifier to circulate the air in your room. Low power settings will require more time, preferably around 12 hours, to clean a room, whilst high power settings will take only a few minutes.

While this may seem like an advantage of high power settings, they are not ideal since the air circulation is increased significantly, causing health risks in vulnerable individuals. You should keep your purifier on a low power setting until it has fully cleaned your room.

2. Type of Air Purification System


When HEPA-type filters power your purifier, the air circulation in your room is increased. This causes the air in your room to be purified in few minutes, leaving you with a clean room. HEPA filters are highly effective at removing allergens from the air.

3. Size of the Room


Research has shown that it takes longer for an air purifier to clean a larger room. This is because there is more surface area in a larger room to create the negative ions and take up the pollutants in the air. Moreover, it is important to match the size of your room with the power setting recommended by your manufacturer to ensure you have an effective purifier.

4. Pollutant Type


The most efficient factor in how long it takes an air purifier to clean a room is the type of pollutant. For example, pollutants like pollen and mold spores are lighter than air. This means that they will move up into the atmosphere quickly once your purifier starts working. On the other hand, heavier pollutants, like smoke particles, will take longer due to their weight.

5. Number of Pollutants


Finally, you should consider how many pollutants your room contains when choosing an air purifier and deciding on a power setting. If you live in a home with multiple occupants, it may be best to consider having a high-power setting on your purifier in the homes with the highest allergens. It also depends on the cleanliness of the house itself.

Pollutants that cause Air Pollution In Homes

1. Pet Dander


If you have pets in your home, you need to look for an air purifier that can remove pet dander. Pet dander is common in most homes with one or more pets. It is a byproduct of animal skin cells that are carried into the air by the animal’s hair. 

2. Dust Mite 


Another common pollutant found in homes is dust mites. Dust mites are tiny insects that feed off dead human skin cells in the air. They are common in most homes with pets, especially cats.

3. Pollen


Pollen is another pollutant that is common in homes with trees nearby. The wind carries pollen grains to coat your home’s windows and walls during times of rain or windy days. Their size is similar to that of the fine dust particles in the air. 

4. Smoke Particles 


Smoke particles are hazardous to people with asthma since they can trigger allergic reactions in sensitive people. These particles are much larger than the air pollution particles, around 0.1 micrometers in size.

5. Molds 


Molds are another common pollutant found in homes and public spaces, caused by moisture and humidity. These molds are highly dangerous to humans, causing asthma-like symptoms and respiratory illnesses.

6. Chemical Pollutants


Chemical pollutants in the air can be problematic for some people, causing the same symptoms as allergens and pollen. The most common chemical pollutants in the air include tobacco smoke and industrial chemicals.

7. Dust Particles


Dust particles are found in every home, and there is no way to get rid of them completely. There are two major types of dust particles: fine dust and coarse dust. Fine dust particles typically come from our homes’ heating systems, carpets, and fabrics. Coarse dust particles, on the other hand, come from industrial activities or cars outside your home.
