The legalization of marijuana in many states has led to an increase in indoor smoking. While this has opened doors for recreational and medicinal use, it has also introduced a new challenge: the lingering smell of weed smoke. Fortunately, there’s a solution to this problem: air purifiers. Specifically, the Levoit Core 400S air purifier, which is designed to eliminate weed smoke and its associated smell, ensures your home remains fresh and healthy.

Why Choose an Air Purifier for Weed Smoke?

Air purifiers are essential for maintaining good indoor air quality. They work by combining an internal filter and fan to pull in unwanted particles from the air in a specific room. The purified air is then circulated back into the room, boosting indoor air quality.

When it comes to weed smoke, air purifiers with activated carbon and HEPA filters are particularly effective. They tackle the issues raised by smoking marijuana head-on, leaving your home feeling fresh and healthy.

The Levoit Core 400S is a high-performing air purifier that stands out in its class. It effectively cleans the air in rooms up to 403 square feet, making it ideal for medium-sized rooms. The unit’s clean air delivery rate (CADR) of 260 isn’t the highest in the class, but it’s pretty good considering the size of the unit and the other Features it offers.

The 400S has an air quality sensor that automatically turns on the unit when airborne particulates reach an undesirable level. This feature helps prevent the buildup of airborne particulates and odors, ensuring your space remains fresh and healthy.

In terms of noise, the 400S isn’t too loud when set to high, and its fan is almost undetectable when set to low. The unit also offers a sleep mode that dims the interface lights and further reduces fan noise.

The device Features a touch-sensitive control panel within a vented ring at the top. This is where users can turn the device on and off and adjust the settings. A series of color-coded indicator rings also tell you how clean your air is right now, from red (bad) to green (good).

Design and Usability

The Levoit Core 400S is a sleek, white cylinder that’s thoughtfully designed. It Features two handles on either side of the device for easy moving around the home. A futuristic-looking black vented ‘wheel’ sits at the top of the device, within which a display screen allows users to view air quality data, fan settings, filter status, auto mode, and sleep mode.

The device is remarkably easy to use. This ease of operation comes without sacrificing Features to simplify the interface and settings.

Price and Value
