5-Stage Cleaning Mechanism

This is perhaps one of the most notable features of this air purifier. This makes it outdo the performance of most of its competitors. With this, you can expect that it is going to eliminate up to 99.99% of all the dirt that is found in air. The carbon pre-filter is the first step, which also helps to get rid of odor. It also has nano-silver anti-microbial treatment, which allows the bacteria and viruses to be killed.

284-Square Feet Room Coverage

This may not be the most impressive when it comes to coverage, but admittedly, it is better than most of the options that you can currently find in the market. If it is going to be used in a large room, it would be best to operate it under Turbo Mode. This will help to improve the speed of the unit, although when in its maximum setting, you can expect some noise to be apparent. It is, however, not as loud and annoying as the sound of other units.

Smart Air Sensing Technology

This model functions like it has a mind of its own, making it easier for users to have it operated. For instance, it is able to detect the quality of air in the room and based on such, it will adjust its functionality. This automates the adjustment of the fan speed depending on what the unit assumes is best for the condition of air. It also automatically turns to sleep mode.

  • Easy to Maintain: One of the best things about Winix WAC9500 Air Cleaner is the fact that it will be effortless to maintain. Even changing the filters will not be too much of a hard work. Even through the years, its superior quality can be retained without demanding too much effort on your part.
  • Extensive Filtration Mechanism: When compared to others within the competition, this is perhaps one of the products that is most impressive when it comes to ability to filter the air as it undergoes five different stages.
  • Comes with a Remote Control: Even without the need to go near the unit, you can easily change the settings based on your preferences as it comes with a remote.
  • Operates Quietly: It is also a good thing that it is quiet, making it ideal for bedrooms. Nonetheless, as it has been earlier pointed out, it is quiet only when used in normal speeds. When in Turbo Mode, it can produce a bit of noise, but still, it won’t be bothersome.


  • Expensive Replacement Filters: Depending on the extent of use, you need to have the filters replaced to maintain optimal functionality. In most instances, this should be done at least once in 6 months. However, one of the problems with this model is that the replacement can be quite costly.
  • Produces a Bad Smell: There are also some people who complained that it can produce a foul odor, especially when it is new. However, this won’t last long. Within a few days, it will naturally disappear.


Indeed, you will not run out of good reasons to choose Winix WAC9500 Air Cleaner above many others within the marketplace. The 5-stage filtration is more than enough to convince you that this will indeed be worth your money. It also has automatic sensing technology. It automates various functions, such as the adjustments of the fan settings. When it is used in a larger room, activate the Turbo Mode and you won’t have to wait for a long time before it does its job. It comes with a well-designed control panel. Plus, it also has an included remote control.
