How Effective Are Air Purifiers? Myths About Air Purifiers You Should Stop Believing

Air purifiers have become increasingly popular as people become more conscious of the air quality in their homes and offices. With the rise in pollution levels, allergies, and respiratory illnesses, having an air purifier seems like a no-brainer. However, as with any popular product, there are numerous myths and misconceptions surrounding air purifiers. Some believe they are ineffective, while others think they are just an expensive fan. Many are confused about what they can filter out, and some even believe they can substitute for skipping the regular cleaning of their living spaces. So the question ‘how effective are air purifiers?’ is still a debatable topic for many. In this blog post, we will debunk some of the most common myths about air purifiers and provide you with the facts you need to decide whether an air purifier is right for you.

Rooms with Air Conditioners Don’t Need Air Purifiers

It’s a common misconception that rooms with air conditioners don’t need air purifiers because the air conditioning system filters the air. While it's true that most air conditioning systems have filters, they are designed to trap large particles like dust and hair. These air filters cannot capture smaller airborne

particles like pollen, pet dander, mold spores, or pollutants like smoke and volatile organic compounds (VOCs).

Air purifiers, on the other hand, are specifically designed to filter out these smaller particles. Most EnviroKlenz air purifiers use a High-Efficiency Particulate Air (HEPA) filter, which can capture particles as small as 0.3 microns. This means these air filters can remove pollutants from the air that an air conditioner cannot.

Additionally, air conditioners recycle the air inside the room but do not bring in fresh air from outside or remove pollutants. HEPA air purifiers, however, actively remove pollutants from the air, making it cleaner and healthier to breathe.

While air conditioners can help reduce the larger particles in the air, they are not a substitute for air purifiers. If you are concerned about the air quality in your home or office, it is recommended to use an air purifier and an air conditioner. So, if your question is, ‘Does an air purifier work?’ Then the answer is definitely it does.

At High Pollution Level, Air Purifiers are of No Use

Another common myth about air purifiers is that they are ineffective at high pollution levels. So do air purifiers reduce CO2? The effectiveness of an air purifier depends on several factors, including the size of the room, the type of airborne pollutants present, and the capacity of the air purifier. However, this does not mean that air purifiers are of no use in highly polluted areas.

In fact, air purifiers are especially beneficial in areas with high air pollution levels. They can remove a significant amount of pollutants from the indoor air, making breathing much healthier. Air purifiers can make a significant difference in the air quality inside your home or office, giving you fresh and clean air.

It is important to choose an air purifier with the appropriate capacity for the size of the room and the level of pollution. A high-quality air purifier with a high-efficiency particulate air- HEPA filter and an activated carbon filter can remove various pollutants, including particulate matter (PM), VOCs, and odors. In case you live in a region of high CO2 concentration, air purifiers reduce CO2 effectively.

Air purifiers and UV air sterilization machines can improve indoor air quality. Therefore, it is recommended to use air purifiers in areas with high pollution levels. So, if you are confused about
‘Whether does an air purifier help’ to reduce pollution levels, then it does.

Air Purifiers Work When Doors and Windows Are Closed

Many people believe that for an air purifier to be effective, all doors and windows must be closed. While it is true that closing doors and windows can help to maintain a more controlled environment and maximize the efficiency of the air purifier, it does not mean the air purifier won't work at all if there is some open space.

Air purifiers work by circulating and filtering the air in a room. If doors or windows are open, the air purifier will still clean the air in the room, but it will also continuously try to clean the incoming air from outside. This could make the air purifier work harder and reduce its overall efficiency because it processes more air than it would in a closed room.

Therefore, while air purifiers can still function with open doors or windows, it is recommended to close them to maximize the device's efficiency.

Bad Odors or Poor Indoor Air Quality Means The Air Purifier is Not Working

Another common misconception is that if you can still smell bad odors, the air purifier is not working. This is not necessarily true. Most air purifiers have filters that can remove particulate pollutants from the air, such as dust, pollen, and pet dander. Many air purifiers are equipped to remove odors.

Odors are caused by volatile organic compounds (VOCs), which are gaseous pollutants. To remove odors, air purifiers with an activated carbon filter are best. This type of filter is specifically designed to capture VOCs and neutralize odors.

If your air purifier is equipped with an activated carbon filter, it will be able to remove odors from the air. Therefore, if you are concerned about odors, choosing an air purifier with an activated carbon filter is important.

All Air Purifiers Are Same

This is a widespread myth that couldn't be further from the truth. Air purifiers come in various sizes, capacities, and features and are designed to address different needs and concerns.

1. Filter Types: The type of filter used in an air purifier is one of the most important differences. Some air purifiers use HEPA filters to capture particulate pollutants, while others use activated carbon filters to remove gaseous pollutants and odors. Some models combine both HEPA filters and carbon filters to provide more comprehensive air cleaning.

2. Capacity: The capacity of an air purifier refers to the size of the room it can effectively clean. Some air purifiers are designed for small rooms, while others are suitable for larger spaces.

3. Noise Level: The noise level of an air purifier can vary significantly from one model to another. Some are very quiet, while others may produce a noticeable noise level.

4. Mobility: They also differ in terms of mobility. Large spaces have central air purifiers, while many offices have portable air purifiers for a single room.

Choosing an air purifier appropriate for your specific needs and the environment in which you will be using it is essential.

You Have to Spend a Lot of Money to Get a Good Air Purifier

The belief that you must spend a lot of money to get a good air purifier is a common misconception. While it's true that there are many high-end air purifiers on the market with advanced features and higher capacities, there are also many affordable options available that are very effective in improving indoor air quality.

The key to finding a good air purifier at a reasonable price is to consider your specific needs. Determine the size of the room where you will be using the air purifier, the types of pollutants you are most concerned about, and any additional features that are important to you, such as noise level, energy efficiency, or smart capabilities.

There are many air purifiers available that offer a good balance between price and performance. For example, a basic air purifier with a HEPA filter and an activated carbon filter can be very effective in removing common pollutants from the air and can be found reasonably priced.


In conclusion, it's essential to be informed about air purifiers' real capabilities and limitations. Through the different information shared in the blog, you definitely have the answer to the question, ‘Are air purifiers effective or not?’. They are incredibly effective devices for improving indoor air quality, but they are not a one-size-fits-all solution. By understanding the common myths and misconceptions surrounding air purifiers, you can decide which air purifier is right for you and how to use it most effectively. Remember to consider your specific needs, the size of the room, and the types of pollutants you are most concerned about when choosing air purifiers. Ultimately, an air purifier is valuable in creating a healthier living and working environment.
