Best Air Purifier for 1000 sq. ft. Large Room Reviews

If you want a good-looking purifier that covers 1,000 square feet of space, this Bissel model may be perfect for you. It looks like a vintage radio set with its front-mounted mesh pre-filter which captures airborne debris. The short faux wood legs which lift the device off the ground also add to its antique aesthetic. The dial on top operates the digital display and controls fan speed and switches between modes. There is an activated carbon filter inside as well as a HEPA filter that captures particles down to 0.3 microns.

  • Lends a classic look to any room
  • The filters are easy to change
  • The fan is large and works well for circulating air in bigger spaces

This extremely versatile, medical-grade air purifier delivers the power you need to clean the air in rooms 1,000+ square feet in size.

  • Reduces pet and smoke odors too

Benefits of an Air Filter for 1000 Square Feet

One of the benefits of using an air purifier that is rated for 1,000 square feet or more is that you will be able to use it in any room of your house.

Most of them offer “whisper-soft” operation or sleep modes too so you don’t have to worry about excess noise. These larger models also typically come with large filters which means they are able to trap more debris and contaminants in the air – better for heath and air quality.
