How Blueair Classic Models are the Same

The Blueair Classic series consists of four model numbers:

What you’ll find with these models is that they share five excellent features in common. Regardless of the model number you choose, you’ll enjoy these aspects listed below.

1) HEPASilent® technology

HEPASilent Technology

All Blueair Classic air purifiers contain HEPASilent┬« technology. This feature is an enhanced version of the High Efficiency Particulate Arrestance (HEPA) filter that’s used in competitor products.

The HEPASilent® technology is unique because it produces the highest rate of clean air delivery along with the lowest levels of noise.

Each model captures 99.97% of airborne particles down to 0.1 microns in size and is whisper silent.

Standard HEPA filters are only capable of capturing particles as small as 0.3 microns and do produce louder noise.

2) Energy Efficient

Each Blueair air purifier is backed with the Energy Star rating. This ensures that every unit meets the guidelines set by the U.S. Environmental Protection Agency and the Department of Energy.

The average cost to operate a Blueair air purifier is equivalent to the energy required to run a single household light bulb.

3) Award Winning Design

We could dedicate a whole article outlining the various awards and special mentions that Blueair has received for their air purifying products, but to save time we’ve listed the top five acknowledgments below.

No matter which Blueair product you choose: 203, 403, 503 or 603, you’re getting an air cleaning product that has an award winning design.

4) AHAM Certified

A final aspect that you’ll find through the Blueair Classic series is that each model is independently verified by the Association of Home Appliance Manufacturers (AHAM) and exceeds the Clean Air Delivery Rate (CADR rating) requirements.

This ensures that you’re getting a top-of-the-line air purifier that’s dedicated to producing the cleanest air possible.

5) Magnetic Filter Timer

All Blueair models come with a magnetic filter timer that you can attach to the unit, refrigerator, or anywhere else.

This timer counts down and alert you when it is time to change the filter.

This ensures that you’re never getting anything less than the highest quality air inside your home or office.
