how to clean an air-purifier’s filter · what to do when the filter gets dirty · how to wash an air-purifier filter
Whether a purifier filter can be cleaned depends entirely on its type. Screen/mesh-type filters cannot be cleaned — they must be replaced.Electrostatic-precipitation (ESP) filters must not be rinsed in water (soaking destroys their electrostatic charge), and should instead be blown clean with a blower. Only some simple washable filters can be rinsed directly. Never use any cleaning agent, and never scrub with a brush — both damage the filter media. It is also wise to clean the purifier’s interior and exterior regularly. Above all, blind cleaning backfires: identify the filter structure first, then act.
Air quality has a direct bearing on everyday life, yet pollution indices in most cities today run high and our living environment is under real pressure — illness linked to dirty air is a steep price to pay. To counter this, air purifiers have found their way into more and more homes. But after months of use, problems crop up, and the easiest to tackle is cleaning some of the unit’s parts. Here is how to clean the filter properly.
I. How to Clean the Filter
- Do not blindly rinse the filter with water. Some filters simply cannot be water-washed. If your unit uses a screen/mesh-type filter, once it gets dirty you can only replace it — it cannot be cleaned.
- If the filter is an electrostatic-precipitation (ESP) filter, never put it in water. Soaking it destroys the electrostatic function, so after reinstalling it will no longer capture dust. Such ESP filters can only be cleaned with a blower or air gun to dislodge the debris on them.
- A few simple filters may be washed directly with water. So before cleaning, distinguish the filter’s structure — different filters call for different methods.
II. What to Watch When Using the Purifier
- After a period of use, clear away debris both on the surface and inside the unit, so normal operation is not affected.
- When cleaning the filter, add no cleaning agent — it breaks down the filter media’s structure. Plain water soaking is enough, and do not scrub with a brush. These actions all damage the filter’s physical structure; it may look clean, but its performance is actually the worst.
