Levoit Vital 100S Smart True HEPA Air Purifier

Introduction

The Levoit Vital 100S Smart True HEPA Air Purifier is a compact yet powerful air cleaning solution designed for medium-sized rooms up to approximately 219 square feet. Combining advanced filtration technology with smart features, this purifier delivers clean, allergen-free air for healthier living environments. Its True HEPA filter captures 99.97% of airborne particles as small as 0.3 microns, including dust, pollen, mold spores, pet dander, smoke, and volatile organic compounds (VOCs). The addition of a high-efficiency activated carbon filter further neutralizes odors and harmful gases, making it ideal for homes, apartments, and offices.

What sets the Vital 100S apart is its integrated AirSight™ Infrared Dust Sensor that continuously monitors air quality in real time and adjusts purification speed automatically. The air quality indicator uses a colored LED ring to provide instant visual feedback, while the unit’s light detection sensor dims panel lights in dark rooms for quieter nighttime operation. Smart connectivity via the Vsync app allows remote control, scheduling, and access to detailed air quality data. These features make it a perfect choice for allergy sufferers, pet owners, and individuals seeking effortless air quality management.

Priced competitively in the mid-range segment, the Levoit Vital 100S usually retails between $130 and $160, depending on the retailer and promotions. It is widely available online and in major appliance and home goods stores. This air purifier blends performance, convenience, and smart technology into a sleek, compact design that fits seamlessly into modern interiors.

CARE & MAINTENANCE

Cleaning the Smart Air Purifier

• Unplug before cleaning.
• Wipe the outside of the air purifier with a soft, dry cloth. If necessary, wipe the housing with a damp cloth, then immediately dry.
• Vacuum the inside of the air purifier.
• Do not clean with abrasive chemicals or flammable cleaning agents.

Check Filter Indicator
will light up as a reminder to check the filter. Depending on how often you use the air purifier, the indicator should turn on after about 9 months. You may not need to change your filter yet, but you should check it when it lights up.  
When your air purifier is set up with the VeSync app, you can also check the app to see the remaining filter life. You will also receive a notification from VeSync when it’s time to check your filter.  

Note: The VeSync app uses a scientific algorithm to determine your filter life based on air quality, amount of use, and other factors. The filter life percentage is based on 12 hours of daily use. 

CARE & MAINTENANCE (CONT.)

Cleaning the Pre-Filter
The Washable Pre-Filter should be cleaned every 2–4 weeks to increase efficiency and extend the life of your filter. You can set a reminder in the VeSync app to clean the pre-filter every 2, 3, or 4 weeks. Clean the pre-filter using a soft brush or vacuum hose to remove hair, dust, and large particles. Optionally, you can wash the pre-filter with water and a mild detergent to remove dirt and dust. 

Note: Avoid scrubbing, scraping, or vigorously brushing the pre-filter. Do not use abrasive cleaning materials.

CARE & MAINTENANCE (CONT.)

When Should I Replace the  Filter?
The True HEPA / Activated Carbon Filter should be replaced every 9 months. You may need to replace your filter earlier or later, depending on how often you use your air purifier. Using your air purifier in an environment with relatively high pollution may mean you will need to replace the filter more often, even if the Check Filter Indicator is off. 
You may need to replace your filter if you notice:  

• The air purifier does not effectively filter certain odors anymore
• Increased noise when the air purifier is on
• Decreased airflow from the top of the air purifier
• Unusual odors
• The HEPA filter is visibly dusty or discolored after removing the pre-filter. Note: 
• To maintain the performance of your air purifier, only use official Levoit filters. For more information, contact Customer Support (see page 26).
• Remember to reset the Check Filter Indicator after replacing the filter (see page 17).

Replacing the Filter

1. Unplug the air purifier, then pull the front cover to remove it (see Getting Started, page 7).
2. Push the pre-filter’s tabs inward and pull to remove the pre-filter.
3. Remove the old filter from the air purifier.
4. Clean out any remaining dust or hair inside the air purifier using a vacuum hose. Note: Do not use water or liquids to clean the air purifier.
5. Remove the plastic packaging from the new filter and place the filter and pre-filter inside the air purifier (see Getting Started, page 7)
6. Replace the front cover.
7. Plug in and turn on the air purifier. Reset the Check Filter Indicator (see page 17).

TROUBLESHOOTING

VESYNC APP TROUBLESHOOTING
My smart air purifier isn’t connecting to the VeSync app.

• Make sure your phone has Bluetooth® turned on and is not currently connected to another Bluetooth device.
• During the setup process, you must be on a secure 2.4GHz Wi-Fi® network. Confirm that the network is working correctly.
• Make sure the Wi-Fi password you entered is correct.
• There should be no spaces at the beginning or end of the password.
• Test the password by connecting a different electronic device to the router.
• If you’re manually typing in the SSID and password, double-check that both are entered correctly.
• Try moving your air purifier closer to the router. Your phone should be as close as possible to your air purifier.
• Your router may need to be at a higher location, away from obstructions.
• Make sure your air purifier and router are away from appliances (such as microwave ovens, refrigerators, electronic devices, etc.) to avoid signal interference.
• If you’re using a VPN, make sure it’s turned off while setting up your air purifier.
• Disable portal authentication for your Wi-Fi network. If portal authentication is enabled, the air purifier will not be able to access your Wi-Fi network, and setup will fail.

Note: Portal authentication means that you need to sign in to your Wi-Fi network through a web page before you can use the Internet.

My air purifier is offline.

• Make sure the air purifier is plugged in and has power, then refresh the VeSync menu by swiping down on the screen.
• Make sure your router is connected to the internet and your phone’s network connection is working.
• Delete the offline air purifier from the VeSync app. Swipe left (iOS®) or press and hold (Android™), then tap Delete. Reconfigure the air purifier with the VeSync app.

Note: Power outages, internet outages, or changing Wi-Fi routers may cause the air purifier to go offline.
