Blue Air 450e Air Purifier 2021 Review

BlueAir 450E

BlueAir HEPASilent450E (403) Air Purifier Review

The BlueAir HEPASilent 450E air purifier uses an electrostatic (air ioniser) technology and a HEPA type air filter to remove allergens, dust and bacteria from the air. The base BlueAir air purifier does not have carbon so we would not recommend this air purifier for odor removal.

The 450E features a digital display and a filter replacement indicator, dust/gas sensor, and timer. The 403 model is the same without the digital display. There is an option to upgrade to the SmokeStop filters for gas removal and these filters are $119.95.

Approximate Price: $629

REVIEW STATS

Ease of Use Rating

1.9 out of 2

The BlueAir air purifier is simple to set up and operate. We simply removed the air purifier from the box and plugged it in. The power controls are intuitive and access to the filter was easy as well. The filter requires replacement every 6 months.

Air Flow

1.7 out of 2

The 450E air purifier delivers 240 cfm (cubic feet per minute) of filtered air and is rated to clean rooms up to 365 sq ft range( 18’ x 20’). We were expecting a little more air flow for the price. The noise level at the highest fan speed is similar in noise level to other leading HEPA air purifiers.

Filter Efficiency

2.5 out of 3

The BlueAir air purifier removed over 98% of the particles that were passing through the air filter on the low speed, however when tested on high speed the efficiency was approximately 90%. Overall this places the Blueair air purifier in the top tier of air purifier performance.

Consumer Feedback

2.6 out of 3

In scouring the web for customer reviews we found 64% of reviews gave the BlueAir air purifier a 5 star rating and a 4.0 star rating overall. Many positive comments were given for the quality of construction and good air flow for a smaller sized room. Several of the reviewers were pet owners and reported very positive experiences in the BlueAir air purifier being able to effectively remove the dust and pet dander.

The key negatives that were reported is the frequent filter replacements, noise level that is produced on the higher fan speeds, the blue light that can't be turned off and a few occurences where the unit stopped operating.
