While it can be tempting to buy the first air purifier you come across, this is not always the best option. In this article, we’ll look at the pros and cons of air purifiers and what you should be looking for when buying one. Our tests were conducted in an open-plan living room that is 600 square feet. We used professional atmospheric research equipment to test the air quality of different purifiers, including a TSI 3080/3010 Scanning Mobility Particle Sizer and a TSI 3321 Aerodynamic Particle Sizer.
Among the most important features of an air purifier is its ability to filter pollutants. The first factor to consider is the CADR, which measures the amount of filtered air the device can process in a given period of time. It is important to note that not all companies use this rating system, so it’s important to check the CADR of each model before purchasing it. Also, keep in mind that not all air purifiers have the same CADR, and the difference in these two metrics may make recommendations more difficult.
When it comes to choosing an air purifier, make sure to look for one that uses HEPA filters. These air cleaners are the most effective at cleaning air and are safer to use than most other models. Some models also feature a gas filter, which is usually activated carbon. This type of filter is helpful for general gas and odor removal, but it is not as effective at removing formaldehyde. Other types of air purifiers use other types of media such as potassium permanganate.
While air purifiers are helpful for cleaning the air in your home, they can also be a waste of money if you fail to take the necessary precautions to improve indoor air quality. This is because air that is circulated indoors can be more polluted than outdoor air. You may find that the air quality inside your home is worse than it is outside, so you need to ensure that you have good ventilation for your home to reduce the risk of seasonal allergies.
Some air purifiers can target specific sources of pollution, such as printers and furnaces. But others work best for general air quality in homes. Those in areas affected by pollution or a natural disaster should opt for models with HEPA air filters. Furthermore, if you have allergies, you should consider buying an air purifier with an activated carbon filter. A high-quality air purifier will help keep your air free of VOCs and pollen.
