Levoit Air Purifier Maintenance (Easy Red Light Fix)

Levoit is one of the leading air purifier manufacturers in the market, boasting millions of satisfied customers. With a wide range of products, from simple one-button air purifiers to advanced smart app-controlled models, users may often encounter problems or issues when using them.

Although Levoit air purifiers are very easy to use and maintain, there is always something easy to miss, so I have written this simple how-to and troubleshooting guide, which I believe can be helpful if you have issues with your Levoit.

Levoit air purifiers generally come with a 1-year warranty, which can be extended to 2 years by registering the device on the official website. Not every malfunction is a malfunction; the warranty doesn’t cover every unusual situation that happens to you. I will cover some of the problems in this article, so keep reading.

How To Set Up Levoit Air Purifier?

Of course, not every air purifier is the same, and not every air purifier is set up in the same way. However, I have tested almost all available Levoit air purifiers so far, and I can say that they mostly follow the same principles and require the same procedure before the first start.

As I said, the preparation for starting a Levoit air purifier is almost identical on all models, so for each new Levoit air purifier you buy, you will need to do the following steps:

1. The first thing you need to do is remove the Levoit air purifier from its packaging.
2. The next step is to prepare the filters, which, with Levoit, are usually wrapped in plastic film and MUST be unwrapped. To do this, you typically open the lid on the bottom or front of the device and remove the filter. Note that the cover on the LV-PUR131 is on the back.
3. After removing and unpacking the filter from the device, put it back in the device and close the lid.
4. Now that the device is ready to work, it is recommended that you place the Levoit air purifier at least 15-20 inches away from the wall or other objects, plug it in, and turn it on.

Suppose you have purchased one of the Levoit smart devices. In that case, I recommend that you download the VeSync app on your smart device and connect your Levoit to the app immediately after setup. This will give you many additional options and make it easier to use your air purifier.

What if You Have Problems Connecting Your Levoit With the VeSync Smart App?

Connecting your Levoit to the VeSync app is a very smooth process that doesn’t require advanced techniques. You can easily check this by visiting the Android or iOS store and checking the app’s rating, which is rated much better than some apps from other air purifier manufacturers.

However, there can always be connection problems, so here are some solutions that can help with the connection problems.

If you can’t connect the VeSync app and the Levoit device, I suggest checking that your internet modem is supported and works at 2.4GHz. If it works on 5GHz, switch it to 2.4GHz and connect it again.

In addition, try to keep the devices as close to the modem as possible, especially if you are using a 5GHz modem, which has a much lower range by default. If none of this works, try using a hotspot from another smart device as a modem to connect the VeSync app and the Levoit device.

What If Your Levoit Air Purifier Smells Bad?

A few users I’ve spoken with through the Air Purifier First website or YouTube channel have complained of unpleasant odors from the filter after unpacking it. Personally, I haven’t experienced this problem with the Levoit air purifier, but I have with some others.

The thing is that the filters have just left the factory, have not been ventilated, and are immediately packed, so the unpleasant smell remains in them. The recommendation and solution to this problem is to leave the unit running for at least 24 hours in a place where you are not around, ventilating the filter and making it fresh.

If this method does not work, leave it for another 24 hours, and if it still fails, I suggest you request a replacement filter directly from Levoit.

How Long Should You Keep Your Levoit Running?

This is a question that bothers many users. The logic is this: Levoit air purifiers mostly use True HEPA filters, which trap particles but don’t kill them. This means that if the room where the air purifier is located is exposed to certain air pollutants, the air will start to worsen as soon as you switch off the air purifier. Therefore, I recommend using the air purifier 24/7 or turning it off periodically if you think the air is clean enough.

Otherwise, you can use Auto Mode, which is a built-in feature in many new Levoit air purifiers.

As for the durability of the air purifier itself, it will last for years, and you don’t have to worry about running it all day.

How Long Does a Levoit Filter Last?

The filters on Levoit air purifiers aren’t washable and need to be replaced from time to time. Small and medium-sized Levoit filters last, on average, about 6 months, but for some larger models, the filters can last up to 12 months.

Fortunately, almost every Levoit air purifier has a filter reset indicator that will tell you when it’s time to change the filter. This means you don’t have to worry when it’s time to change, as the air purifier will track it for you.

How Do You Change the Filter on Levoit Air Purifiers?

As I mentioned before, Levoit does not use washable filters (except the pre-filters on Vital 100S and Vital 200S), which means that the filters on these air purifiers need to be changed from time to time.

Fortunately, the filter reset indicator will let you know when it’s time to change the filter.

The replacement process is straightforward, and usually consists of just a few simple steps, and is very similar to all Levoit air purifiers.

1. To begin with, the filter cover must be opened and the old filter removed.
2. Then it would be a good idea to vacuum the inside of the unit and remove accumulated dust particles, hair, and similar dirt.
3. The next step is to unpack the new filter, insert it into the device, and close the lid.
4. Finally, you just need to reset the filter reset indicator.

I would recommend everyone not to rely entirely on the filter reset indicator and to check the filters from time to time if they are dirtier than they should be and that they should be replaced before the recommended time.

How Do You Clean a Pre-filter on Levoit Air Purifiers?

Levoit usually has a specific type of pre-filter, which is usually a nylon mesh attached to the HEPA filter. This pre-filter stops large particles from entering HEPA and other filters, prolonging the HEPA filter’s life and improving overall air cleaning quality. 

You have to clean a pre-filter at least two times per month. It would be best to vacuum it or clean it with a dry cloth. If you want to learn more about maintaining pre-filters, I have recently written a decent article about pre-filters and how to clean them.

On some other models, the pre-filter is removable, which makes cleaning and maintenance easier. In fact, cleaning a pre-filter is a must and something I strongly recommend.

How Do You Reset the Levoit Air Purifier Red Light?

I think this is the most common question and problem people face with their Levoit air purifiers. Many wonder how to fix the red light, but there is nothing to fix here, as a red light on your Levoit air purifier usually means that it is time to replace the filter. To fix this, simply replace the old filter with a new one. After doing so, make sure to reset the light according to the manufacturer’s instructions (refer to the table below).

To reset the red light (filter reset/check indicator) on your Levoit air purifier, press and hold the filter reset button for about 3 to 5 seconds. If this method doesn’t work, try resetting the indicator with the device turned off but still plugged into the wall outlet. This method is necessary for some models, such as the LV-H128, which requires resetting the indicator while the device is switched off.

The table below shows the Filter Reset Indicator reset procedure for all Levoit air purifiers.

Levoit LV-H126	This one doesn’t have an air quality indicator. It has a filter reminder wheel that you can use to track when it’s time to change your filters.

Levoit Air Purifier Fan Not Working

The biggest problem you may encounter is of a technical nature, such as, in this case, a situation where the fan is not working.

Unfortunately, suppose you have correctly connected the device to the power supply and checked the adapter (some Levoit air purifiers have it). In that case, I don’t think there is a solution to this problem other than to contact Levoit support directly and claim the warranty.

If this problem occurs, I suggest that you do not disassemble the unit or try to fix anything yourself, as this could invalidate your warranty.

I have the same advice if the Levoit air purifier does not work if neither the LEDs nor any of the buttons on the device work.

Further Suggestions

Although I have answered almost all the problems users encounter with Levoit air purifiers, you can always encounter some less specific faults. However, to keep your air purifier working without issues and offer high-quality air quality in return, it is always best to do regular maintenance. I wrote about air purifier maintenance tips and guides not long ago, so make sure you check that guide too.

In any case, my recommendation is that if you encounter something that I haven’t explained in this tutorial, please contact Levoit directly via their website, email address, or mobile phone. You can also get them via Facebook, where they are also very up-to-date and reply to messages very quickly.
