BlueAir 403

BlueAir 403 Review Summary

The Good:
Just like any other Blueair air cleaners, the 403 comes with an energy efficient HEPA Silent filter and a quiet motor.

The Bad:
You need to change the filter every 6 months.

The Bottomline:
The Blueair 403 still maintains the efficient and energy saving filter used by it’s bigger siblings. But with only 1 filter and negligible amount of carbon in it means that it will not help much with odor or smoke problem.

What we like about the Blueair 403.

The filter: BlueAir 403 uses the HEPASilent air purification system like any other machines made by the company.

It works like this. Before dirty air is sucked through the filter, the machine uses ion brushes to charge if first. So, while air purifiers made by other companies force the air through their filters, this one makes the charged contaminants attracted to the filter.

And because the dirty particle willingly cling to the filter, the HEPASilent can have larger holes than a normal HEPA. As a result, you get a quiet and efficient cleaning machine.

Filter is easy to change: The unit is designed so that you can change the filter without using a screwdriver or any other tools.

Practical: The unit is made of galvanized steel and can be moved around using it’s built-in carry handle. There’s also a timer that counts down from 6 months to remind you when to change the filter. And because it so quiet, there’s a blue power on light to let you know if it’s on operation.

Uses little electricity: It only consumes 30 Watt on low and 70 Watt on high speed.

It’s silent: Because the filter has better airflow than a HEPA filter, the Blueair 403 is one of the quietest machine in it’s class. Suitable for your bedroom or study area.

Our Concern :

• The Price: It only covers a relatively small area but the cost is similar to machines that cover twice the area.
  
• The filter cost: At around $120 a year for 1 filter, it is one of the most expensive replacement filter in it’s class.
  
• Warranty : You need to change your filter every 6 months or the 10 years warranty will be void.
• No carbon : Because it lacks a specialized carbon filter, it won’t handle smoke, gases or odor well.
• No pre-filter : Most air cleaners come with pre-filter to stop bigger airborne particles from entering the main filter. But this one lacks one. We suggest you vacuum your filter to help it lasts longer.
• Movability: Yes, there is a carry handle but at 33lbs, castors are better.
• Not automatic: There’s only manual dial to adjust the 3 fan speeds. There’s no automatic sensor to adjust the speed according to the pollution level. At this price, we expect to find one.
