Purifiers aren't just for allergy sufferers or hypochondriacs. The EPA lists indoor air pollution as one of the top five environmental risks to public health, which is no small matter considering most people spend up to 90 percent of their time indoors. We've rounded up five models you won't be ashamed to display.

• 

  Winix Plasma Wave 9000

  • Made by: Winix
  • Price: $549
  This top-of-the-line model combines solid design with cutting-edge technology. The five-step purification process will rid any room of viruses, bacteria, and your uncle’s cigar smoke tout de suite. The 9000 has every bell and whistle imaginable save a cup holder: remote control, ultra-quiet operation, dust and odor sensors, to name a few.
• 

  Hoover SilentAir 2000

  • Made by: SilentAir
  • Price: $129
  This purifier is so popular in Japan that it’s been incorporated into bullet trains. The fanless setup, which relies solely on ionization, produces a low buzz rather than the quiet hum of the fan-based models. The SilentAir is also compact, energy-efficient (costing about $4 per year to operate), and has no moving parts to wear out.
• 

  Bluair 201

  • Made by: Blueair
  • Price: $299
  The Blueair’s multidirectional airflow circulates more volume than most, ensuring that untreated particles are cleansed. Its galvanized-steel construction will outlive plastic cases, even if it does look like an old PC server. More than durable, the ionic chamber and three-stage HEPA filter of this Energy Star model will cleanse toxins without breaking the bank.

  Winix Plasma Wave 5000B

  • Made by: Winix
  • Price: $229
  The 5000B uses a three-step filtering process, has filter alert and odor-sensing features, and doesn’t use ozone to neutralize chemical vapors and allergens. The all-black exterior shell, complete with blinking lights and LEDs, reminds us of the WOPR from WarGames; just don’t challenge it to a tic-tac-toe match.

  IQAir HealthPro Compact

  • Made by: IQAir
  • Price: $649
  The IQ’s aesthetic is more institutional than the others, which makes sense since it’s the top choice of hospitals worldwide. Quality is key here. The IQ doesn’t do anything differently, it just does it better. The modular filter design saves money by replacing individual components rather than buying expensive and unnecessary parts. Now if somebody would just design a cover for it.
