Air purifiers work by using filters to remove airborne contaminants from the air. The type of filter used will determine what kind of contaminants the purifier can remove. HEPA filters, for example, are designed to capture smaller particles, while activated carbon filters can help to remove odors and VOCs (volatile organic compounds). The model of purifier you’d likely buy for your small home office won’t be powerful enough to clean the air in a large living room.

However, weighing in at almost 20 pounds, the Rabbit Air MinusA2 is one of the heaviest units we tested. Despite this, our tester liked having the option to mount it on the wall to free up floor space. On high, it measured quieter than most of our top picks—at around 61 decibels (or similar to a normal conversation). The purifier also features a low-noise operation, making it perfect for use in bedrooms or other areas where a loud purifier would be disturbing.
Small and medium-sized Levoit filters last, on average, about 6 months, but for some larger models, the filters can last up to 8 months.

Not all air purifiers are created equal, as some are designed for small rooms while others have a larger capacity. For example, the GermGuardian Pluggable Small Air Purifier wouldn’t work in your living room because its coverage area is only 50 square feet.
