Winix PlasmaWave 5300

Winix has long been synonymous with quality air cleaning products, and the PlasmaWave 5300 is no exception. It has been designed to purify the air in mid/large sized rooms up to 350 square feet. Aside from the PlasmaWave technology used with this model (which is unique to Winix), this unit boasts the fact it uses ‘true’ HEPA filtration. This means that 99.97% of all air pollutants as small as 0.3 microns will be removed.

Review Details

One of the most discerning qualities with this Winix air purifier is the PlasmaWave technology used. Many other models in this price range use ionizers which produce ions that attach themselves to the pollutants in the air, causing them to fall to the floor. This means consumers are often left with a cleaning job.
With the 5300, there is no need. The technology used doesn’t just weigh the particles down, it breaks all vapor, allergens odor and chemical particles down which eliminates the production of harmful ozone.

Other useful features with this model include 4 fan speeds and an automatic air quality sensor. When this air monitoring system detects more pollutants in the air, the unit will automatically adjust its speed setting accordingly.

What We Liked

  • Three Stage Filtration
    Equipped with a pre-filter to capture larger particles such as lint and hair, the 5300 has been designed to help increase the lifespan of the HEPA filter. It will also capture a broad range of troublesome particles such as odors, allergens, dander and mold spores.
  • Advanced Particle Removal Technology
    There is no need to worry about harmful ozone with the 5300 due to the patented PlasmaWave technology used. Particles caught by ions will not just be weighed down; they will be broken down at the molecular level.
  • Ease of Use
    Fitted with 4 fan speeds and an automatic particle sensor, the consumer has little need to worry about the air quality in the room.
  • Added Extras
    Included with the 5300 is a pack of 3 carbon filters which eliminates the need for replacement for 1 year.

What We Didn't Like

  • PlasmaWave Option
    With this air purifier, the PlasmaWave option cannot be turned off, which is a little annoying for some consumers. However Winix have designed the unit this way to help enhance air quality.
  • Automatic Sensor
    On its highest setting, this air purifier can be a little noisier than other models in this price range. This can be distracting if it automatically switches to a higher fan speed.


The Winix PlasmaWave 5300 rates well above average overall and many consumers have reported it’s highly efficient at improving the quality of air in their homes. It has also been commended for the reduction in symptoms people suffer from due to allergies. The advanced filtration system with this unit cannot be matched by other manufacturers at the price at which it’s offered. If noise is an issue, consider the Whirlpool AP51030K or the Blueair 203. They may be more expensive, but they are very quiet, especially on sleep mode (Whirlpool only).
