Air purifiers are a popular household item for many people looking to improve the air quality in their homes. With so many different options available on the market, it can be difficult to know which one is the best fit for your specific needs. In this article, we will take a closer look at the features and technologies of air purifiers, and provide some tips on how to choose the right one for your home. Whether you're looking to remove allergens, pollutants, or simply improve the overall air quality in your living space, an air purifier can be a valuable addition to your home. From HEPA filters to UV-C light technology, we'll explore the different ways air purifiers work to clean and purify the air in your home. So, if you're ready to breathe easier and enjoy cleaner air in your home, read on to learn more about the world of air purifiers.

Filter Types

Air purifiers use a variety of filters to remove pollutants and other contaminants from the air. In this guide we will cover some of the most effective & widely used filters.

HEPA filters - High-Efficiency Particulate Air (HEPA) filters are considered the gold standard for air purification. They are able to capture at least 99.97% of particles as small as 0.3 microns in size, including allergens, dust, and pet dander. It's important to note that not all HEPA filters are true HEPA, so it's best to look for air purifiers with certified true HEPA filters to ensure the best air cleaning results.

Activated carbon filters - These filters are made of carbon that has been treated to increase its surface area. They are effective at removing odors and volatile organic compounds (VOCs) from the air.

Pre-filters - These filters are typically made of mesh or foam and are designed to capture larger particles before they reach the HEPA filter. They help prolong the life of the HEPA filter by trapping larger particles and reducing the amount of debris that the HEPA filter has to process.

Ultraviolet (UV) light filters - UV filters use UV-C light to kill bacteria, viruses, and other microorganisms. They are typically used in conjunction with other types of filters to provide added protection against these types of contaminants.

CADR Rating

CADR stands for "Clean Air Delivery Rate." It's basically a way to measure how well an air purifier can clean the air in a room. It's like a score that tells you how quickly and effectively an air purifier can get rid of things like dust, pollen, and smoke. It's measured in cubic feet per minute (CFM), which tells you how much air the purifier can clean in a certain amount of time. So, if a purifier has a high CADR rating, it means it's really good at cleaning the air in your room, and it can do it quickly. If you're looking for an air purifier, you should definitely check the CADR rating to make sure you're getting one that's powerful enough for your needs.

Room Coverage/Floor Area

Air purifier room coverage is an important aspect to consider when purchasing an air purifier. It refers to the amount of space that a particular air purifier can effectively clean and purify. It is important to choose an air purifier that can cover the size of the room or space you want to use it in. If the air purifier is not powerful enough to cover the entire room, it will not be able to effectively clean the air and remove contaminants such as dust, pollen, and other allergens. On the other hand, an air purifier that is too powerful for a small room may be a waste of energy and money. Therefore, it's important to choose an air purifier with the right coverage for the room size in order to ensure that you are getting the most out of your purchase and keeping the air in your home as clean as possible.

Noise Level

Air purifiers are great for keeping the air in your home or office clean, but one thing to keep in mind when shopping for one is the noise level. Some air purifiers can be quite loud, especially on high speed setting, which can be disruptive to your daily life. Some purifiers have a noise level as low as 24dB, which is almost silent, while others can reach up to 55dB, which can be quite loud. If you're planning on using your air purifier in a bedroom or other quiet space, it's important to look for one with a low noise level. Some models even feature a "sleep mode" which will automatically lower the noise level when you're trying to sleep. Additionally, you can look for models with sound absorbing materials, or with a noise level below 50dB which is considered as low noise level.

Filter Replacement

Air purifiers rely on filters to capture and remove pollutants from the air. These filters need to be replaced periodically in order for the air purifier to continue to effectively clean the air. The frequency of filter replacement varies depending on the specific air purifier and the level of air pollution in the room. Some air purifiers have filter replacement indicators that let the user know when a filter needs to be replaced. It's important to note that using non-genuine replacement filters can be unreliable and may even damage the air purifier, so it's important to always use the correct replacement filters as recommended by the manufacturer. Regularly replacing the filters is crucial in ensuring the air purifier continues to perform at its best and keep the air clean.
