Winix air purifier 6300-2 vs. 5500-2 review and comparison:

WInix 6300-2 and 5500-2 are products from the same category. So, most of the technology and features of both the products are very similar and effective. From the above table, it is clear that even their size and dimensions are the same. In this article, I will discuss the factors that make these devices similar and some key differences between them. So, I suggest that you read the whole article before finalizing your purchase.


Design and color:

The last few generations of Winix air purifiers have been design-driven. The performance and quality of Winix products are stronger, more durable, and more efficient than ever before. The body of their air purifiers is made of durable plastic and uses metal parts as needed. It ensures that your air purifier remains protected from environmental hazards such as mold and corrosion.

Winix 6300 and 5500 have similar designs, dimensions, and color schemes. The elegant black color provides a very professional look to the device. So, your new air purifier will go well with every theme in offices and homes. Moreover, their structure is a work of art. The visitors can’t stay back but compliment the elegance of these air purifiers.

At first glance, it is hard to spot a difference between Winix 6300 and 5500. The main reason is that the audience very well received the 5500-2. So, Winix decided to keep their signature look on the newer devices. The only way to distinguish between the two is to have a closer look at the filters and control panel. The 6300-2’s control panel has a few improvements that only experts can detect.

Overall, both Winix 6300 and 5500 have a minimalistic yet classy look. The black color and simple control panel can enhance the beauty of your interior. Moreover, they have a design that resembles some of the high-end luxurious air purifiers in the world. So, any of these devices will surely become a piece of attention for your guests.


Filtration system:

The 6300 and 5500 have a four-stage filtration system. Nowadays, brands are trying to include as many filters as possible to increase their device’s efficiency. For instance, the higher number of stages can remove more pollutants and deliver clean air at a faster rate. In this regard, Winix stays ahead of every other brand with its Plasmawave technology.

So, if you compare the efficiency of any Winix air purifier with any other brand, Winix is always the winner. For the sake of simplicity, I will explain the benefit of each of the four stages of filtration:

  • Pre-filter:

    The first filter stage consists of a basic mechanical filter. It contains over 2000 microholes for filtering solid contaminants such as dust, soil, and animal hair from the air. This is a permanent filter, which means that you can wash it every month instead of buying a new filter.

  • HEPA filter:

    The second stage of the air purifier is the most effective. Modern air purifiers are not efficient without at least one HEPA filter. This filter captures small particles of 0.3 microns without clogging for several months. However, this is a disposable filter and should be replaced as soon as it appears on display.

  • Active-carbon filter:

    The third stage of the air purifier is after the HEPA filter. Air is free of most solid particles but still contains smoke, VOCs, odors, and smoke. Therefore, the activated carbon filter acts like a magnet and attracts carbon-containing compounds from the air.

  • PlasmaWave:

    Most air purifiers stop filtration at the activated carbon filter, and the air is returned to the room. But what about bacteria, bacteria, and viruses? Therefore, Winix is ​​one step ahead of most other air purifiers in its category. They use UV lamps to break down the DNA of all harmful microorganisms in the air and break them down.


What makes the WInix 5500-2 better?

As you might have noticed, the 5500-2 is very similar to the 6300-2. The one game-changing factor that makes the 5500-2 better is its washable carbon filter. The activated carbon filter is disposable in most air purifiers and requires replacement every 4-6 months. However, the 5500-2 comes with a washable carbon filter that you only need to wash once or twice per month. As a result, the total maintenance cost of the 5500-2 is comparatively lower than the 6300-2, as you only need to replace the HEPA filter.


Control panel:

The control panel of xx00 series Winix air purifiers is very different from the C-series. For instance, the C-series has the control panel at the front while the panel is located at the top on 5500 and 6300 air purifiers. Moreover, you get slightly fewer controls as none of the devices feature a WIFI connection to your smartphone.

The First button in the panel is the power button to turn the machine on or off. Next comes the auto-mode selection button. The mode button allows you to switch between auto and sleep mode quickly. In the auto mode, the device uses the information gathered by the smart air quality sensor, and the fan speed is adjusted according to the pollution level in the room. However, none of the panels feature any way to monitor the room’s current air quality. Similarly, the sleep mode reduces the noise levels, dims the device lights, and sets the fan speed low.

The Plasmawave switch is present at the center of the control panel. According to research, the Plasmawave can affect the respiratory system of some individuals as it triggers asthma and allergic reactions. Therefore, Winix allows the users to control the Plasmawave according to their liking.

The fan speed button is next to the Plasmawave switch. You can choose from 4-speed levels and a bonus turbo setting. The amount of power used by the air purifier depends on the fan’s speed. Decreasing the fan speed will reduce the filter rate but improve energy efficiency, whereas higher fan speed enhances the performance and adds more to the electricity bill.

The last button on the control panel is the timer switch. You can choose between 1. 4, and 8-hour settings to automatically turn off the device. Finally, the check filter indicator lets you know as soon as it is time to replace the HEPA filter with a new one. The reset button is useful to recalibrate the device whenever you install a new replacement filter. Otherwise, the check light won’t turn off.



The 240CFM clean air delivery rate of the 6500 and 5500 air purifiers is more than enough to cover small to medium rooms. So, the device is more than enough for small offices and living rooms. However, the 6300 covers slightly more area than the 5500-2. This slight difference can easily become a decisive factor when choosing between two of the most powerful air purifiers by Winix.

Some users have also experienced a slight breeze when sitting close to the Winix air purifiers. It is because the powerful fan increases the airflow, making it slightly cooler. Similarly, the 4x ACH rating of both these air purifiers allows the machines to run four times per hour. This allows clean air to circulate in the room every 15 minutes and ensures that new air quality is maintained all the time.


Features of Winix 6300 & 5500:

  • The washable filter in the 5500-2, while the 6300-2 has eight layers of carbon filters.
  • High CADR and ACH scores.
  • Elegant and minimalistic design
  • Low maintenance cost
  • Auto mode and Sleep mode

Pros & Cons:


6300-2 5500-2
Plasmawave technology Plasmawave technology
8-carbon filters Washable Carbon filter
Higher area coverage High CADR score
Smart sensor Smart air quality sensor
The replacement filter is slightly expansive The carbon filter is slightly inferior to the 6300-2





What is the Plasmawave technology?

The Plasmawave technology is an advanced air filtration mechanism that uses positive and negative charges to filter the air. First, the particles are provided a charge, and an opposite charge is induced on the filters. As a result, the pollutants are attracted to the filter. Similarly, the negative ions penetrate the bacteria and viruses at the DNA level, and they die.


Which is better? Winix 6300-2 or 5500-2?

Both devices are very similar in terms of design, color, performance, and features. However, the 6300-2 has 8-activated carbon filters and can cover up to 400 sq. ft room in under 30 minutes. On the contrary, the WInix 5500-2 has a washable carbon filter, and the smart air sensor is optimized for a large number of pollutants. So, both the devices are powerful and effective if used for the right purpose.


Does Plasmawave technology emit ozone?

Yes, the ions produced by the Plasmawave filter interact with the atmospheric oxygen. The ions convert oxygen molecules into volatile oxygen atoms. These singular oxygen atoms again interact with atmospheric oxygen to produce ozone, a harmful greenhouse gas.

O2 + Ions è O + O

O + O2 è O3 (ozone)



WInix is a well-known brand of heavy-duty air purifiers. Most industries and businesses use Winix devices for their higher performance, low maintenance cost, and advanced features. For instance, no other brand in the world provides the Plasmawave technology in its devices. In this regard, both 6300-2 and 5500-2 are some of the most effective air purifiers in the market. So, people are often confused about which one to buy for their home and office.

Therefore, in this article, I have explained the similarities and key differences between the two. Overall, the Winix 5500-2 is slightly better than the others. However, it doesn’t mean that the 6300-2 is not worth buying. In short, the success of your purchase depends on what you want from your air purifier.
