Blueair 680i Review

The Blueair Classic 680 has many features that make it stand out from other air purifiers sold today. Its unique design and wide coverage area are just a little part of what this equipment can do. Here are the Blueair Classic 680i features

Overall Performance

The high-performance powerhouse falls around the medium to high range class of air purifiers. It comes with a powerful fan and an overall functional design. Its HEPA Silent Technology makes it easy to capture up to 99.99% of the pollutants in the air. It comes with Wi-Fi support which makes it easy to control the purifier from any location. You can easily pair it with your Alexa, and most importantly, it falls in the category of devices with an energy star rating.

Most people have the misconception that high-range purifiers only come with one air filter. The Blueair Classic 680i proves them wrong as it packs a Dual Protection air filter system. The air purifier effectively gets rid of toxic odors from pollutants like the Volatile Organic Compounds from vehicle exhausts, smoke, and many other contaminants. While the Blueair Classic 680i air purifier may be expensive, it is one of the most efficient and effective air purifiers you can get today. It has the best cleaning capabilities compared to other models and is one of the best of Blueair’s models.

Filtration Technology

This air purifier comes with the latest filtration technology, which is not common in other products. The Blueair Classic 680i comes with a pre-filter designed for larger particles, pet dander, hair, and other small dust particles. Like we mentioned earlier, it effectively absorbs toxic pollutants, and you can expect a lot from this 698 sq ft air purifier. Its filter system is advanced and can go the extra mile compared to other large capacity air purifiers.

Filter Types

The Blueair had two types of filter systems in this air purifier. The company upgraded its filter from its HEPA filters and activated carbon filters combining them with a high capacity filter system. The two innovative filter technologies used in this Blueair air purifier are the HEPA Silent Technology and the Dual Protection Filters.

HEPA Silent Technology

The Blueair air purifier is an upgrade from the standard HEPA filters, which are known to create noise due to their mechanical interaction. This new technology removes 99.99% of pollutants like bacteria and viruses. It is properly tested and proven using GB/T18801-2015 standards. The standard third party test for airborne viruses and bacteria. The HEPA Silent Technology comes with a special cleaning sensor that has a combined mechanical and electrostatic filter design. It works just like magnets as it draws particles to its filter material.

Dual Protection Filters

The Blueair Classic 680i also comes with the Dual Protection filters. This high capacity filter adds to the cleaning capacity of this air purifier. It removes dirt particles as tiny as 0.05 micrometers in size. It is highly effective and better than the standard HEPA filter, which normally removes larger particles measuring up to 0.3 microns. The Dual Protection filter is also effective in getting rid of viruses and bacteria as well as other harmful pollutants.

The combined use of both the HEPA Silent Technology and Dual Protection Filters in the Blueair Classic 680i makes it one of the best in the market. It is only high-quality purifiers that are designed with these two filters.

Coverage Area

The Blueair Classic 680i has an impressively large coverage. With its 698 sq. ft. capacity, it can be used in a very large room in your home. This air purifier is also suitable for medium-sized apartments. The Blueair 680i air purifier comes with a dimension of 26 x 20 x 13, which qualifies as an almost industrial-grade air purifier. However, it works for medium to large spaces. You can conveniently use it in your home, office, and even in commercial spaces.

CADR Rating

The CADR rating determines how effective your air purifier is, and this Blueair Classic 680i has a 400-450 rating. Its incredibly high CADR rating proves that it performs beyond capacity. The average CADR rating for most air purifiers is at 200, and this shows that the Blueair 680i air purifier is a powerhouse. Its CADR rating is verified by AHAM after passing the standard testing procedures for measuring air purifiers ratings.  It can effectively work large spaces and comes with 5ACH (air changes per hour). The number of the air changes shows you how often the air in your living space is cleaned. It is especially effective for people who struggle with allergies or have respiratory issues. You can change the number of ACH between 3, 4, and 5 ACH.  The Blueair air purifier can effectively clean the air every 12 minutes when it is set at 5 ACH.

Indicators and Controls

Another unique feature of the Blueair Classic 680i is its indicators and controls functions. It comes with an automatic mode and sensors.
