Blueair 450E

H ave you ever wondered how many impurities there are in the indoor air you breathe daily and how they can affect the health of your respiratory system? If you have, then you certainly have decided that you need an air purifier and you should take a look at the Blueair 450E.

Although the $629 price tag places it among the most expensive units, the high performance and the excellent results in eliminating air pollutants promote it as one of the best purifiers. You can fit it in any medium to large rooms in your house and leave it to do its job without even knowing it’s there, considering how silent and convenient it is.

The high performance is due to a combination of two types of filters, namely the SmokeStop and particle filter. The SmokeStop media is responsible for the removal of odors and gasses, whereas the second is a True HEPA filter that evidently tackles the majority of polluting particles, even those that are microscopically sized. The Blueair’s HEPASilent technology provides highly efficient filtration by combining the electrostatic and mechanical filtration, resulting in a higher power without causing an operation that might be deemed too noisy.

The Blueair 450E has a CADR score of 240 CFM for smoke, dust, and pollen, and as it produces 5 air changes per hour, meaning that once every 12 minutes it retakes its operation to ensure clean air indoors, it is a system you can rely on to provide optimal airflow and thorough air purification. It has been designed to successfully handle air filtration in rooms up to 365 sq. ft. in size. Being an Energy Star rated unit, it keeps the energy consumption low enough to increase its functionality.
