Reasons Red Light Turns On And What To Do

What are the reasons the red light in your air purifier turns on? Let's find out below. We also tackle how to resolve these issues.

Dirty Or Clogged Air Filter

By turning on the red light, an air purifier can alert you when the filters become dirty or clogged.

It is prudent to clean or replace the filters as soon as the red light comes on since the air purifier won't effectively clean the air if the filters are dirty. Furthermore, running an air purifier with dirty filters can damage it.

How To Clean Your Levoit Filters

You first need to disconnect your appliance from the power to protect yourself from a potential electric shock that can seriously injure you. Next, clean or replace the filters. 

Most air purifiers, including a Levoit, are fitted with a pre-filter and HEPA filter. Some may have up to three filters. Levoit manufacturers recommend that you do not wash the HEPA filter. Instead, replace it every six or eight months.

However, you can clean the pre-filter at least every two weeks or once a month. To do this, hold the pre-filter under running water for a few seconds, let it dry completely, and then install it back into the appliance.

Remember to reset your air purifier after cleaning or replacing the filters.

High Level Of Pollution In The Air

Sometimes, a room can be heavily polluted. For instance, if smoke happens to enter a room, the red light will turn on. This is because your appliance is overworked trying to purify the smoke-filled air.

You can try moving your appliance to a room with no smoke to solve this problem.

Overwhelmed Device

In other instances, the red light will illuminate for no reason other than being overwhelmed. In this case, you do not need to clean it or replace anything. You only have to reset it by holding down the lit button for a few seconds and then releasing it.

How to maintain your air purifier in good condition

The following are extra tips on how to take care of your air purifier: 

Clean The Rooms Regularly

Your air purifier will work better when the surrounding area is clean. Too much dust causes the air purifier to overwork, reducing its lifespan. So, regularly clean the rooms in which you are using these appliances.

Place Your Air Purifier In A Suitable Area

A sealed room is the best place to place your air purifier since it will concentrate on purifying the air without contaminants finding their way into the room. If the doors or windows are open, the purified air will escape, thus wasting the clean air. 

Never Use Detergents

Do not attempt to use any detergent to wash your filter or air purifier. You might cause damage. It is enough to run the filter under water and wipe the gadget with a piece of cloth. 

Place It In The Center

How To Troubleshoot Your Air Purifier

Sometimes minor issues can crop up, preventing your air purifier from working. The following are some problems that can occur and how to troubleshoot them:

Not Powering Up

An air purifier failing to power up is not always an indication of a major problem. So, do not panic if there's no sign of power after switching on your appliance. You could have forgotten to plug into an outlet, which you should if it is not.

If it does not work after plugging, plug it into another electrical outlet. If the new outlet works, call an electrician to repair the faulty one. 

Also, if the power rating on your appliance and the electrical outlet is not similar, power will not flow. For this reason, use an outlet with the same rating as your gadget. 

Unusual Noises 

If you hear unusual sounds from your appliance, open it and examine the filter. In some instances, you may have wrongly installed the filter. Install it correctly, and then close your air purifier.

If the noise persists, there could be something more serious. In this case, call a technician to diagnose the problem. 

Unpleasant Odors

Most unpleasant odors emanate from dirty filters, which is simple to solve. Washing or replacing them is the solution. 

Effects Of Not Washing Or Changing The Filters On Time

There are negative effects of not changing the filter per the schedule recommended by the manufacturer. They include:

Increased Health Risk

Your air purifier can clog up to levels where it can no longer trap dirt and debris. The dirt trapped in the filters creates a good breeding ground for microorganisms such as mold, bacteria, and viruses to thrive. As a result, you risk respiratory infections.

Compromised Quality Of Air

Dirty filters cause the level of filtration to drop significantly, compromising the quality of the air you breathe. The air will not be as fresh as it should be.

Higher Energy Bills

Severely clogged filters will cause your air purifier to work extra hard. This will cause your home's energy consumption to rise, increasing your energy bills.
