Clearing the Air: Should Everyone Have an Air Purifier at Home?
Delving in to the science around air purifiers, their benefits and my experiences since buying one.
Indoor air pollution is a serious concern, with studies showing that the air inside our homes can be even more polluted than the air outside. Poor air quality can lead to a variety of health issues, including respiratory problems, allergies, and even chronic illnesses. Air purifiers are devices designed to improve indoor air quality by removing pollutants and contaminants from the air.
In this blog post, we will explore the science behind air purifiers, the benefits they provide, and how to choose the right air purifier for your needs. By the end of this post, you will have a better understanding of the importance of air purifiers and how they can help you and your family breathe easier and live healthier lives.
The Science of Air Purifiers
Air purifiers work by using various technologies to remove pollutants and contaminants from the air. Different types of air purifiers use different methods to clean the air, and each method has its own strengths and weaknesses. Here are some of the most common types of air purifiers:
* High-Efficiency Particulate Air (HEPA) filters: HEPA filters are considered the gold standard of air purifiers. They are capable of removing 99.97% of particles as small as 0.3 microns, which includes most common indoor pollutants like dust, pollen, and pet dander.
* Activated carbon filters: Activated carbon filters use a porous material to absorb pollutants like chemicals and gases. They are particularly effective at removing unpleasant odours from the air.
* Ionizers: Ionizers use an electric charge to create negatively charged ions, which attract and trap positively charged pollutants in the air. The pollutants then settle on nearby surfaces, where they can be removed with a vacuum or wiped away.
Each of these types of air purifiers works in a slightly different way, but they all have the same goal: to remove pollutants and contaminants from the air we breathe. Whether you're looking to reduce allergens in your home, remove unpleasant odours, or just breathe cleaner air, there is an air purifier out there that can help.
The Benefits of Air Purifiers
Air purifiers offer a wide range of benefits for those who use them, including:
Improved air quality and reduced indoor air pollution: Air purifiers are designed to remove pollutants and contaminants from the air, which can improve air quality and reduce the amount of indoor air pollution. This is especially important for people with respiratory issues, like asthma or allergies.
Reduction of allergens and asthma triggers: Air purifiers can help remove common allergens like pollen, dust, and pet dander from the air, which can reduce the frequency and severity of asthma and allergy symptoms.
1. Improved respiratory health: By removing pollutants and contaminants from the air, air purifiers can help improve respiratory health and reduce the risk of respiratory illnesses.
2. Improved sleep quality: Cleaner air can lead to better sleep quality, as pollutants in the air can cause irritation and discomfort that disrupts sleep.
3. Reduced risk of illness and infection: Air purifiers can help remove airborne viruses and bacteria from the air, which can reduce the risk of illness and infection.
4. Improved overall health and wellbeing: Breathing clean air can have a positive impact on overall health and wellbeing, reducing stress and improving mental clarity.
In short, air purifiers can help create a cleaner, healthier, and more comfortable indoor environment. Whether you are looking to improve respiratory health, reduce allergy symptoms, or simply breathe easier, an air purifier can be an effective tool for achieving your goals.
Choosing the Right Air Purifier
When it comes to choosing an air purifier, there are several factors to consider. Here are some of the most important ones:
1. Room size: The size of the room where you will be using the air purifier is an important factor to consider. Make sure to choose an air purifier that is designed for the size of the room you want to use it in. If the air purifier is too small, it may not be effective at removing all the pollutants from the air, while an air purifier that is too large may be unnecessary and cost more than you need to spend.
2. Type of pollutants: Consider the type of pollutants you want to remove from the air. If you are looking to remove allergens, a HEPA filter air purifier is likely your best option. If you want to remove odors, an activated carbon filter air purifier may be a better choice.
3. Budget: Air purifiers come in a wide range of prices, so it's important to consider your budget when choosing one. Keep in mind that more expensive air purifiers may have advanced features, like air quality sensors, that can help justify their higher price tag.
When it comes to specific brands and models of air purifiers, there are many to choose from. Some popular brands include Levoit, Dyson, and Honeywell. To determine which air purifier is right for you, consider reading reviews and comparing features and prices.
Ultimately, the key to choosing the right air purifier is to identify your specific needs and match them with the features and capabilities of different models. By doing your research and taking the time to choose the right air purifier for your situation, you can breathe easier and enjoy the many benefits of cleaner, healthier indoor air.
My Personal Recommendation and review: Levoit 400s Air Purifier

As someone who suffers from allergies and asthma, I had been on the lookout for an air purifier that can help me breathe easier and reduce my symptoms for quite a while. On and off. After countless hours of comparing purifiers from price to size, performance to noise levels, I decided to give the Levoit 400s Air Purifier a try (link is provided above, and I may earn a small commission from this at no extra cost to you), and I have to say, I am only sorry I didn't purchase it sooner.
The Levoit 400s is a sleek and modern air purifier that is designed to remove a wide range of pollutants from the air, including allergens, dust, smoke, and pet dander. One of the features that sets the Levoit 400s apart from other air purifiers is its advanced filtration system, which includes a true HEPA filter and an activated carbon filter. The true HEPA filter is capable of capturing 99.97% of particles as small as 0.3 microns, while the activated carbon filter helps to remove odors and other volatile organic compounds (VOCs) from the air.
Another standout feature of the Levoit 400s is its smart functionality. The air purifier can be controlled through a smartphone app, allowing you to adjust the settings, monitor air quality, and set a schedule for the air purifier to run. I found this to be incredibly convenient, as it allowed me to easily customize the air purifier's settings to my specific needs.
In terms of performance, the Levoit 400s did not disappoint. After using it for several weeks, I noticed a significant improvement in the air quality in my home. I no longer woke up with a stuffy nose or experienced breathing difficulties, and I noticed a reduction in the amount of dust and pet hair in the air. Additionally, the air purifier operates quietly, making it easy to use in a bedroom or other living space without disrupting daily activities.
One stand out point is the cost to run the air purifier. The Levoit 400s is energy efficient, very energy efficient. According to the manufacturer, the estimated annual energy cost to run the Levoit 400s is around $14/£12, which i can verify. I am regularly using pennies per day to run mine with a mixture of high and low power modes, and also sleep mode overnight in my bedroom. Which is extremely low cost compared to other air purifiers on the market. Additionally, the cost to replace the filter varies depending on usage and environmental factors, but it is a small fee, i believe, to maintain the benefits that it has provided me.
Overall, I am extremely satisfied with my purchase of the Levoit 400s Air Purifier. It has significantly improved the air quality in my home and helped me breathe easier, reducing my allergy and asthma symptoms. I would highly recommend this air purifier to anyone looking for a high-quality, effective air purifier with advanced features and smart functionality.
So it's over to you. I have given you a brief overview of the science and benefits of air purifiers. I personally believe every household could benefit from running a purifier often, even over night. I know it has helped us at home greatly and the impact has been significant.
You only get one set of lungs, why not start giving them extra care?
