Why Is My HoMedics Air Purifier Blinking Red | Explained

I get this question a lot on my blog; why is my HoMedics air purifier blinking red? The answer is that it is time for you to change the UV-C bulb because it’s no longer usable due to the broken filament.

You do not have to switch your panic button on, as this is quite normal. The LED light on the instrument panel is there to tell you if the purifier is working properly.

While the whole lot may seem unfamiliar stuff for you, it is actually quite trivial. The handyman within you has to come out for this, but the whole replacement process is very straightforward.

What Is the Purpose of The UV-C Bulb?

Before we get into the solution, let’s understand the purpose of the UV-C bulb in your HoMedics air purifier.

Unseen to the naked human eye, countless microorganisms are floating in the air, and among these, many may be pathogenic. If these pathogens are not killed or destroyed, then they may make you sick when inhaled.

The whole concept of putting this bulb into the air purifier is to inactivate these disease-causing microorganisms.

Ultraviolet light, which has a short wavelength, is created and inactivates these microorganisms. All in all, the job of this bulb is to ensure that the air you breathe is healthy and the environment you are in is fresh.

Does the UV-C Bulb Require to Be Changed Frequently?

No, not really. The bulb that has been installed into the air purifier can be functional for more than 10,000 hours. That’s a very long time, and even if you use your device frequently, it shouldn’t be a problem.

Now, it really narrows down to how much you use it and how well you take care of the machine.

A Guide to Fixing the Blinking Red Problem

Once you see the light going off, you must replace it, or else the machine will start performing poorly. But do note that- it will not completely stop working.

You can get somebody else to do the replacement, but you can do this on your own too.

Take Out the Cover of the UV-C Bulb with Precautions

Though it’s a pretty basic thing, let me remind you to turn the purifier off before you start. Also, remove the power cord from the outlet, as it is unsafe to have it plugged in while replacing the components. Also, the components inside might get damaged in this way.

Next, you need to work on the HEPA-type filter and remove it from the cover, and then with the help of a screwdriver, take out the two screws from the UV-C bulb. Be sure to store them somewhere safe. The cover will come off after that.

Remove the UV-C Bulb from the Socket

The bulb will come into your view once you have the cover off. You would need to have gentle hands to carry out the next step. Push the bulb and start rotating it. If too much pressure is applied, there is a risk of the bulb shattering right in your hands. So, be careful.

The Final Step – Installation

We are finally at our last step, where you’re going to install a fresh and working bulb in the air purifier. Carefully place it in the slot; you may need to exert some pressure to install it properly.

However, you have to be gentle with this because the glass may break otherwise. Place the cover over the new bulb by taking both screws and securing them in the middle.

After that, install the HEPA-type filter as the finishing touch and switch on your air purifier. You will see that your red blinking light problem has been solved. The light should now be blue.

What Should Be Done If the Air Purifier Is Still Blinking Red?

There are two things that you can do to solve this particular problem. If the color is still red, check to see if the new bulb is working. Try to switch the device on and off a couple of times to see whether the color changes to blue.

If that doesn’t work either, you can clean your filter. That should do the trick.
