Air purifiers are wonderful devices that benefit our health in many ways. From the less efficient to the more successful, they all seem to have one thing in common – complexity.air purifier are not just a fan that can be turned on and off, making the air fresh and clean. The technology behind some air cleaners is very complex, but since it’s not our focus here so I will leave it up to the scientists to do the research!
If you’ve ever had to purchase an air purifiern or even thought about it, you’ve more than likely come across many different brands that have different features. Some have HEPA filters, some don’t. While some have feature activated carbon filters with no pre-filters at all. To make things easier, lets’ take a deeper look of the two most important parts of air purifiers.
Pre-filters: Having pre-filters inbuilt into purifiers is a big advantage over cleaners that don’t. This is the first step in the filtration process where the pre-filters job is to capture large particles the main filter usually can’t, or particles that get stuck to it. It prevents debris getting into the main filter, and this is why pre-filters come in handy as an additional strength in filter technology.
Pre-filters can be vacuumed, washed, or replaced which helps to prolong the life span of your air cleaning unit. If they are washable, it’s a definite plus because you’re getting an efficient, cost saving unit. A pre-filter needs to be replaced at certain times because it can get damaged and particles such as dust, fur, pollen and hair get stuck.
Activated carbon filters: They are special in a few ways. They capture more dirt and dust than standard filters. These pollutants are usually smaller and harder to catch. Along with that, they also eliminate unpleasant odours in the room. If you’re a smoker, or the house is filled with unwanted smells of any kind, a activated carbon filter is the perfect part in an air purifier.
Activated carbon is also called activated charcoal which goes through a process with oxygen to open up the pores between atoms. The main function of activated charcoal is to adsorb the odours or coloured substances from liquids or gases. Do be aware though that carbon filters can’t be vacuumed or washed, they can only be replaced due to the nature of the job they perform.
There’s also the powerful combination of an activated carbon pre-filter. That’s double the precaution and filtration. Nothing gets through, dust, gases, or smells. Activated carbon filters are rarely used alone to clean the air, but as a helper they work wonders!
