Why Does My Air Purifier Make A Snap?

Air purifiers sometimes make snapping or cracking noises. This sound isn’t made by all sorts of air purifiers but only by air purifiers that come with ionizers.

This might make you wonder why does my air purifier make a snap.

An air purifier makes a snapping sound when its ionizer’s wires catch a large particle. So, you don’t have to worry when you hear a snap from your air purifier.

However, that doesn’t mean that a continuous snapping sound from the purifier is okay.

If you’re concerned and want a fix to this, this article can help as we’ll discuss a few ways of fixing an air purifier that’s making a snappy noise.

Why Does Air Purifier Make a Snap?

Let’s take a deeper look into the construction of ionizer air purifiers. The ionizers come with wires.

Electricity is passed through these wires, and they produce a lot of negative ions. These negative ions attract the dust particles and molecules toward the filter of the purifier.

This happens because when the airborne particles come near the negative ions, the positive ions present in them are attracted. However, only small particles don’t enter air purifiers.

When large particles enter the air purifier, they too are attracted by the electric mesh net, and when they come in contact with the wires, they make a snap sound.

As you can see, an occasional snap would be pretty normal as large particles are bound to enter the air purifier. It’s a problem when the air purifier is making a continuous snap. In the later section, we’ll discuss how to fix that.

How to Prevent Air Purifiers from Making Snap Sound?

Now, we’ll take a look at a few steps that’ll help you fix the air purifier snapping sound.

Turn the Device Off

Wear a pair of gloves so that you don’t get electrocuted. Make sure to get insulated gloves. Turn the device off and take the plug out.

Now, take the outer brackets off of the air purifier. Note that you shouldn’t work with the device turned on or plugged in.

Clean Loose Debris on the Wires

Air purifiers make a continuous cracking sound when there’s loose debris on their wires. Cleaning these usually solve the problem.

So, look for the electric cells on your air purifier. A standard air purifier should come with two electric cells. Take each out and clean them properly with a brush.

However, don’t vacuum these as doing so can damage the filters.

Check the Electric Cells

After cleaning, turn the purifier back on, and all should be fine. If there’s still a snapping noise, there’s something wrong with the electric cells.

In such cases, you need to get the cells replaced.

As you can see, the answer to why does the air purifier make a snap is rather simple. It’s mainly large particles or loosely stuck debris.

Cleaning the electric cells properly will fix the problem for you. If it doesn’t, get the electric cells replaced, and you’ll be fine.
