A dirty purifier is a completely useless appliance. But, getting dirty is sort of what purifiers are designed to do, right? In their simplest form a purifier is designed to pull dirty air through a filter and catch as much of the dust, pollen, etc. as they possibly can. But, the more dirty air the purifier “inhales” the faster the filter fills. Each particle reducing the amount of air the appliance can pass through to the clean side of the filter element. Once the filter is filthy you have two options; replace the element or give it a cleaning.
How do I know when its dirty?
The newer top of the line purifiers can answer that question for you. Through an app, led, or display a modern purifier can tell you when its time to give the filter some love. However, if you’re like us and prefer the more budget friendly purifier variety – you’ll have to use your best judgement.
If the purifier itself looks dirty there’s a good chance the filter element is as well. Another easy way to detect a drop in performance is to listen to the purifier. Does it sound like its struggling? If its making a bunch of noise and exhaling just a light breeze from the “exhaust” its probably time to give the little machine some love.
Why is Cleaning Important?
It is normal for an air purifier filter to be clogged over time due to the frequent operation and it can cause resistance to the machine’s airflow. The amount of debris that an air filter can hold before it becomes too much for it to handle is determined by its efficiency rating. As the air filter becomes clogged, the air purifier will need to work harder than normal.
If the air purifier works harder than usual, it puts a lot of strain on the system, which reduces the air purifier’s lifespan. It also contributes to the increase of power consumption, which also increases the total cost of ownership. Additionally, when air purifier filters become clogged, they trap lesser air contaminants and tend to absorb fewer odors.
The frequency of filter replacement will depend on the type of filter that the air purifier has and the environment where the machine is located. As a general rule of thumb, the majority of air purifiers will need filter replacement every three to six months. However, it is best that you follow the specified schedule of replacement on the manufacturer’s manual.

The pre-filter needs to be washed at least once a month, or more often as necessary. You will need to have the pre-filter replaced in the event that it already is worn or damaged. Do not wash the pre-filter in an automatic wash. Gentle hand wash is only recommended.
Permanent Filter
Here’s how you can clean a permanent filter. As the name implies, permanent filters do not need any replacement. Nonetheless, you need to clean and maintain permanent filters for optimal performance. If the air purifier comes with filter clean indicator, it will alert you if the filter already needs some cleaning. Follow the steps below on how to clean a permanent air filter:
- Make sure to turn off and unplug the machine before doing any cleanup.
- Simply pull on the tab in order to remove the air inlet grill.
- You will need to remove and check the foam pre-filter.
- If it has already accumulated dust or lint over time, remove the accumulated particles using warm, soapy water. Before placing it back into the grill inlet, make sure that you have rinsed and drip it dry.
- You need to check the condition of the permanent filter and if found dirty, you can have it removed from the machine.
- Using a vacuum cleaner, you can clean the filter by running the brush attachment along both sides of the permanent filter and make sure to clean between the pleated layers. Remember that you should not wash the permanent filter using water, detergents or any household cleaners.
- If there any discolorations on the filter, even after vacuuming, you do not need to worry as it is pretty normal and does not affect the filter’s performance whatsoever.
