If you want to keep your Coway air purifier in a good condition, you need to clean its filters and the inside and outside of the unit.
Air purifiers work by circulating the air in your space through a filter, or a series of filters, which trap and eliminate various kinds of dust-particles, pollen-particles, allergen-particles and other unwanted particles from the air in your home.
Why it is important to clean your Coway air purifier thoroughly
In the case of the Coway air purifiers, you will often find that your unit contains three filters, including a pre-filter for larger particles, a deodorizing filter (which is often referred to as a carbon filter) and a True HEPA filter for those miniscule particles.
And over time, dust, grime and other particles can build up on the surface of these filters. This build-up can prevent proper airflow and will place undue strain on the other components within your air purifier.
If you want to prevent your air purifier from getting overworked or even just ensure that it is functioning the way that it is supposed to, it is important to clean every component thoroughly from time to time.

How to clean your filters
If you own an air purifier, you have likely been told repeatedly how important it is that you clean your air filters in order to properly maintain your unit.
However, since the Coway air purifiers have so many filters to trap so many different particles, this process can actually be quite confusing.
To simplify matters, it is important to remember that the pre-filter is usually the only filter within your air purifier which can be cleaned and re-used.
Whereas the deodorizing filter, the True HEPA filter and any other filters within the air purifier need to be replaced entirely every few months.
To clean the pre-filter, you will simply need to remove the filter from its compartment, and then carefully run over it with a vacuum.
If there is any particularly stubborn dirt or grime stuck to this filter, you can gently rinse it underneath some warm (not hot) water. Be sure to let the filter dry completely before putting it back inside the unit.
How to clean the rest of the unit
As for the rest of the unit, you should be able to remove most of the dust and dirt that has built up by quickly running over the inside and outside compartments with your vacuum cleaner.
If you want to really ensure that the unit is completely clean, you may want to scrub it gently with some warm, soapy water.
However, in this case, it is important that you steer clear of any sensitive electrical components and try not to use any harsh chemicals that could damage the unit.
Using a smaller, detail brush, can help you get into all of the nooks, crannies and vents of your unit, to ensure that there is absolutely no obstruction in the unit’s airflow.
It can also be helpful to gently clean the dust sensor (if your unit has one) to make sure that it stays as accurate as possible.
It is critical that you ensure that all of the components are completely dry before reassembling the unit.
How often you should clean your Coway air purifier
Cleaning all of the dust and grime that builds up on your Coway air purifier over time can be oddly satisfying. But in general, it is not a task that you should have to complete all too often.
A fairly general cleaning and replacement schedule for the Coway air purifiers should look something like the following:
| Timeline | Description |
| Every two to four weeks | Clean the pre-filter |
| Every month | Clean the outside of your unit |
| Every two months | Clean the dust sensor |
| When the indicator lights turn on (about once every six to 12 months) | Replace your deodorization filter and/or the True HEPA filter |
