Air purifying devices have gained a lot of popularity over the past few decades as more and more people are becoming health conscious. These devices have been around for quite a while, with technology dating back to the World War 2 era. However, they weren’t used so widely until now. There are a lot of people out there who are looking to buy an air purifier for their homes and personal use. However, many people don’t know the difference between an air purifier and ionizer, this confusion makes it hard to pick the right air purifying device for your use.
These devices work by sucking in air and filtering it, they’re able to trap all kinds of particles ranging from pet hair, dust particles, smoke particles, pollen and more, some air filtering devices are even capable of trapping bacteria. By filtering air these devices provide fresher and cleaner air for breathing, making them great for people with allergies and respiratory system problems such as asthma, and another advantage of filtered air is that it is odorless, air filtering devices can keep interiors free of bad odors.
Now that you know what air purifiers do exactly, let’s take a look at the difference between air purifiers and air ionizers; there’s only one significant difference between the two, and that is how they filter the air. However, this single difference is pretty substantial and makes a lot of difference.
Air ionizers have been around since the 1990s and were very popular for quite some time, these air filtering devices clean out air without using any filter at all, instead they make use of negative and positive charges to trap various particles inside of them and as a result, make the air cleaner. When air passes through them, it gets negatively charged, these charges bond with particles in the air and make them heavier, causing them to get attracted to positively charged plates inside the device and stick on them.
The plus side of ionizers is that they have no filters that need replacing, all you need to do is clean their plates every now and then to ensure efficient cleaning, they’re also effective at getting rid of cigarette smoke particles and tobacco odors that are hard to get rid of. However, these devices have lost their popularity over time due to some reasons.
Ionizers are pretty inefficient at cleaning the air, they manage to trap large to medium sized particles but the smaller and more harmful ones manage to flow through them, and if you don’t regularly clean them out then they only become more inefficient. Another problem with ionizers is that their filtration process produces ozone, ozone helps protect us from harmful radiation in the stratosphere, but closer to the ground it’s considered as more of an air pollutant as it can be unsafe to breathe for people with respiratory problems. Ever since air purifiers have started to have their ozone emissions checked air ionizers have become unpopular, the majority of ionizers currently in use are limited to commercial facilities only.
Air purifiers that use filters to clean out air are currently gaining immense popularity since they are able to clean air extremely well, these air purifiers make use of HEPA filter technology which was developed in World War 2 to be used in gas masks. HEPA filters are able to capture even the tiniest particles and trap them, and their use produces next to no ozone at all, what makes HEPA filters so effective is that they consist of numerous layers that combine to form the filter, and as the filter gets used it becomes even more efficient at trapping airborne particles.
However, this doesn’t mean that you can continue to use one HEPA filter forever, after a while the filter needs to be replaced otherwise it starts to restrict the flow of air, this is the only downside with air purifiers as you have to replace their filters every now and then. Other than this, HEPA filters are currently the best option when it comes to air filtration, and almost every air purifier on the market makes use of them, they’re also used in commercial planes since they manage to capture bacteria and bad odors as well.
Some air purifiers even combine HEPA air filters with ionizing technology to provide even more efficient air filtration, but this increase in efficiency comes with an increase in ozone emissions as well. Air purifiers are set to only become more demanded as time goes on, so it’s best to know as much about them as possible.
