A lot of people think that they are safe from air pollution the moment they escape the outside world and step into their beloved home. That couldn’t be further from the truth. From pet dander and pollen to tobacco smoke and dust, there are different particles that can contaminate the air inside your home, which is bad news if you or your family members have allergies.
The good news is that you can remedy that issue by getting an air purifier, which captures tiny airborne particles and ensures the air you breathe in your home is clean. But don’t just pick any air purifier; there are different kinds of air purifiers. Some are designed for a small bedroom while others are built for a very large room.

The products are listed according to price, in ascending order, allowing you to quickly see which products are within your budget range.
Not all large room air purifiers will cost you more than $200. There are also great options that sell for less than that amount, with the Winix 5500-2 being one of the best.

Additionally, the indicator lights dim when in sleep mode, transforming the machine into a discreet cleaning system that won’t disturb your sleep.

When in auto mode, the fan speed automatically adjusts based on the room’s air quality.
