Filter Change Indicator

The Blueair Classic 203 Slim Air Purifiers intake air through the back of the unit. The air is passed through the pre-filter where large particles are trapped, then through the electrostatic HEPA-type filter where the small particles are trapped, and then through the ionization chamber where the air mixes with negative ions. Negative ions are then released with the clean air through the top of the unit. The ions collide with the particles in the room air and the particles become charged. Then when the air cycles back through the unit, the charged particles cling to the electrostatic filter media. The combined filtration technologies allow the Blueair Air Purifiers to achieve 99.97% filtration efficiency. Blueair Model 301, 402 Air Purifiers Diagram

The Blueair 203 Slim utilizes a different design from the rest of the Blueair models. Whereas, the ionizer in the larger Blueair models is located inside the unit before the filter which charges the incoming particulates as they enter the unit prior to being filtered, the ionizer in the 200 series is located at the top of the unit which releases negative ions into the room, charging the particles in the air. One might wonder if the 203 design is as effective as the one used in the larger models and the answer is yes. The negative ions are released into the air and collide with the airborne particles where they become negatively charged. These charged particles are then drawn into the air cleaner where the electrostatic attraction to the filter surface results in their removal. Since the particles in the room do not receive as strong a charge as in the larger Blueair models, they have compensated by using a higher grade filter media specifically for the 200 series. This gives the 203 the same filtration efficiency as achieved in the other Blueair models.

Pluses:

  • Combines electrostatic and mechanical filtration technology to effectively capture a wide range of large and small airborne particles providing relief from allergy and asthma symptoms
  • Optional Gas & Odor SmokeStop filter has 2 lbs. of impregnated activated carbon to provide sufficient removal of gases, odors, and VOCs
  • Less filter restriction allows for higher air flow while maintaining a reduced noise level for continuous day or night use
  • Easy to operate and changing the filter only takes a couple of seconds with no need for tools
  • Durable steel construction the grills and powder-coated steel exterior are easy to wipe clean, will not pick up grime or oily stains the way plastics can, and will not off-gas
  • Safe use of electrostatic technology without producing ozone
  • Includes a magnetic timer that reminds you to change the filters every 6 months


Summary:

The Blueair Classic 203 Slim air purifier is the perfect choice for someone on a limited budget who wants an efficient, well-made air cleaner for a small room. Blueair has for making very quiet air purifiers, and this one happens to be their quietest. It is even notably quiet on the high speed. Like the other Blueair models, the filters should be replaced every 6 months.  The 203 Slim takes up little space yet, it delivers solid clean-air performance. Overall, a great quiet air purifier for a small room.
