On first looks, the BlueAir 403 HepaSilent Air-Purification System looks rather big and if you plan to use it in a bedroom or in a living area, it is best to keep it next to something big like a wardrobe to ensure that it doesn’t become the centerpiece of the room. The machine is finished to a grey metallic matte feel that goes with the robust power of the machine. The BlueAir 403 is designed for those who like the air in their homes clear as crystal as it is capable of eliminating nearly all the dust and other particles in the room. It is recommended for use in rooms as large as 365 sq.ft but it can be stretched to larger areas provided the right power setting is used.
The BlueAir 403 is an incredibly powerful machine. It is capable of replacing the air in a 365 sq.ft rooms as many as five times per hour. This machine relies heavily on the HEPA filter for its purification, which is a great idea, as these filters are very effective in removing pollutants. In fact, the technology used here is a modification of the HEPA filter and is known as the HEPASilent, which is far quieter than the regular filter. It is for that reason that this machine is indeed one of the quietest in the market today.
When compared with other machines its size, it is easily the quietest and is quieter than a lot of smaller machines too. The key is the design. Though it might look nothing more than a box, it is indeed very effective in cutting down the noise coming from the motor. The specifications on the site say that this machine has a speed control in three stages but it actually has four levels. The lowest is meant for maintaining the current quality of air as it takes a long time to circulate it all efficiently. The higher levels clean effectively but they don’t make much noise either. For a clear idea, it is very easy to make comfortable conversation even if the machine is running in high power in a corner of the room.
The filters that are built into the machine are critical for trapping the large dust particles. These are linked to a sensor and a magnetic display that can be put anywhere in the house which shows when the filter needs replacement. Replacing is an easy job and the best part is that all the filters are recyclable so there is really no environmental damage from using this machine.
The vents of the BlueAir 403 are positioned strategically with nothing on the top or the back. This means that you can position it against a wall and even use the top to put something light on it. Though the vents are only along the side, they are very effective and it is easy to feel the air from this machine at the opposite corner of the room as well.
This machine is great for use at home provided it is reasonably sized as it occupies a little more space than normal air purifiers. However, with a motor as quiet as the one inside this, there should be no problems. In fact, most users were very happy with this machine and there no areas of improvement for this machine with the exception of a reduction in size, which is again very trivial. There are other higher series machines in the same line but they are far louder than this, which easily dominates the air purifier market now.
Pros
- Quiet and very effective air purification system
- Great design for optimum space use
- Recyclable filters
Cons
- Size could be smaller but that is only aesthetic
