Air purifiers can be a great addition to any home, especially if you suffer from allergies or respiratory problems. But how long does it take for an air ionizer to purify the air in a room? In general, you can run an air purifier for a few hours a day and expect it to thoroughly clean the air in your space. If you're only looking at a smaller room, half an hour to an hour can have the same result. That schedule can give you all the benefits of an air purifier without the need for it to be turned on all the time, but you'll want to run it at least once a day for the best effect.
Most air purifiers have several fan settings that affect how quickly they expel air, in exchange for consuming more energy and making more noise. The CADR number indicates the volume of air passing through the air purifier's filters in cubic feet per minute. The CADR is based on the highest fan speed, that is, 5 air changes per hour, but the air purifier is probably not constantly running at the highest fan speed. Some of the best smart air purifiers monitor air quality and display quality readings on the purifier itself or through a connected application.
Second, depending on what the manufacturer determines as “sufficiently poor air quality”, an automatic setting can cause the air in the house to be filled with particles before starting the purifier. This allows you to monitor it much more closely and see how an air purifier affects air quality and obtain accurate figures on how long a purifier should work in a specific space. The higher the MERV, the smaller the particles the filter can trap, which is great for air quality, but it also means that filters with a higher MERV usually take longer to fully circulate through the air in a room. In previous guides, we explained how current intelligent air purifiers work and what specifications to consider when choosing the right size for your room or house, such as the CADR or Clean Air Delivery Rate.
But did you know that the air quality inside your home can be less healthy than outside? Fortunately, an air filter that can clean a room of the right size can help clean the air. However, not all air purifiers are the same, and it's essential to ensure that the one you buy is the best one to treat the most common air quality problems. In conclusion, running an air ionizer for a few hours each day should be enough to keep your home's air clean and healthy. If you're looking at a smaller room, half an hour to an hour should do just fine. Make sure to check out all of your options before buying an air ionizer so that you get one that fits your needs.
