The Blueair 400 series will quietly and effectively clean the air in a medium to large size room. They are available with your choice of HEPASilent particle filters or Gas & Odor Smokestop filters to remove chemical, gas and odor in addition to the particulates. The Digital 450E model features electronic controls including an automatic setting that operates based on the measurement of air quality, plus a filter change indicator, timer option, and remote control.
Pluses:
- Unique filtration combines electrostatic and HEPA-like technology for a performance similar to most residential HEPA filters with the ability to filter particles down to 0.1 micron
- Safe use of electrostatic technology does not produce ozone or off-gas
- Less filter restriction: polypropylene filter media is less dense than HEPA filter material and allows the Blueair to have improved air flow, use less fan power, and reduce noise levels
- Virtually Silent: its high air flow is great for quick cleaning and the lower, almost silent speeds provide the ideal operation level for continuous day or night use when you are in the room
- Blueair's award winning design is not only stylish and offers excellent performance, it also allows for easy filter changes that take less then a minute of your time
- Safe, effective and environmentally-friendly filter media: the 100% recyclable polypropylene filter material is water-repellent and naturally retards mold and mildew growth eliminating the need for chemical-based bacteria or mold inhibitors that are used in many residential glass fiber HEPA filters
- Filter Change Indicator: the 450E has a built-in filter change indicator and the 403 includes a magnetic timer that reminds you to change your filters every 6 months as recommended for optimal performance of your Blueair air purifier
Summary:
The Blueair 400 series are an excellent choice for those looking to clean a room or office up to 900 square feet. We like that one can purchase the Gas & Odor Smokestop models for chemicals, gases, and odors and choose the 450E electronic models for automatic control and filter life monitoring. We would encourage the purchase of the Gas & Odor Smokestop filters for all around filtration to provide the optimum clean indoor environment. The HEPASilent particle filters are good for particle filtration, but do not have any carbon so they will not remove any gases, odors or chemicals from the air. For those who like added conveniences, the 450E Digital models have all the little extras and are easy to operate with a remote control. We would like to see Blueair add a pre-filter to their air purifiers to lengthen the life of the main filter and reduce the frequency of replacements. However, considering they perform very well in all other aspects one can see why most will overlook this fault and are very happy with this air purifier. |
A Blueair air purifier will help you achieve cleaner, more breathable air in your indoor environment without the noise. Virtually silent on low speeds, the 400 series are perfect for a mid-sized bedroom approximately sized at 365 square feet. The Blueair 450E digital air purifier offers some extra perks over the 403 such as a remote control, built-in filter change indicator, air quality sensors, auto-mode and timer function. Using patented HEPASilent and electrostatic technology, these air purifiers capture 99.97% of the tiniest 0.1 micron particles on speed one, including pollen, dust mites, mold spores and pet dander.
