Review

Blueair has five families of air purifiers, with the Blue line at the budget end of the market and the Pro at the top of the line. The Blueair Classic 280i is an impressive air purifier model at a reasonable price point.

However, with so many models in the Blueair line, it can be tricky to find the best one for you. So, here we’ll delve into some of its features, so you can determine if it is a good choice for your home.

Overall performance

The Blueair Classic 280i is an efficient air purifier with varying levels of pollution. The model filters the room air at the industry recommended rate of five times per hour or approximately every 12 minutes in a room up to 279 square feet. This can ensure that particle levels are lowered to maintain a comfortable environment in your living space, bedroom or other areas of your home.

The model has integrated sensors that can auto adjust to the current conditions to maintain a healthy indoor air quality. The 280i has advanced filtration to remove myriad pollutants including airborne bacteria, pollen, mold, dust and gases such as smoke, cooking odors and chemicals. Despite this, the 280i is one of the quietest models on the market and it was even awarded a Noise Abatement Society Quiet Mark.

The 280i has a unique combination of mechanical and electrostatic filtration that Blueair has patented as HEPASilent. This combination creates filters that require less air pressure compared to a standard HEPA filter as they are less dense. Yet, this does not compromise performance, so you can enjoy a more energy efficient and quieter air purification. The unit has a low energy consumption using 20 to 80 watts, which allows you to run the air purifier 24/7 using less energy than a traditional light bulb.

Filtration technology and filter types

Blueair Classic 280i Review: Is It Really Worth Buying?

There are two filter options for this model. The first is a Particle Filter that can capture 99.97% of pollutants including mold spores, dust, pollen, viruses and bacteria, down to a size of 0.1 microns. The other option is a DualProtection Filter. This is a combination of a [trusted_link anchor="True HEPA filter" title="HEPA Filter Benefits for Allergy Relief" url="https://www.webmd.com/allergies/hepa-filters-for-allergies"]WebMD discusses the benefits of HEPA filters for relieving allergy triggers in your home.[/trusted_link] and an activated carbon filter.

The carbon filter uses coconut carbon which can filter compounds up to four times faster than basic carbon filters. This filter is an upgrade option but it does have the benefit of being able to trap gas pollutants such as smoke, VOCs and household odors.

Coverage area

Unlike many air filtration units that are only designed for modest sized rooms, the 280i has a large coverage area. In fact, Blueair specializes in powerful air purifiers, as the 280i’s big brother, the Pro XL has a CAD rating of 1000 cfm.

With the dedicated Blueair app you can remote control fan speed, LED brightness, the child lock and other functions
