Winix 6300-2 weight

Filters And Performance

Winix 6300-2 utilizes the same filter setup as Winix 5300-2 with the addition of a fine mesh pre-filter. Majority of the large particles such as dust, hair and fur would be captured by pre-filter so the carbon filter could perform more effectively in dealing with odors and gases. For micron size particles that could now be seen by naked eyes, you have True HEPA filter standing by. Lastly the permanent PlasmaWave Technology would create Hydroxyls that instantly neutralize all allergens and bacteria without creating any harmful ozone in the process.

The up side is filter replacement cost is not too bad and it comes in a bundled package. Keep in mind that the carbon filter lifespan is at 3 months top so replacing the filter has to be done on a quarterly basis.

Winix 6300-2 VS The Challengers

Winix 5500-2 PlasmaWave

Winix 5500-2

Winix 5500-2 offers very similar spec but a higher grade carbon filter. The drawback to 5500-2 is the 3-stage filtration that lacks a pre-filter.
Winix 5300-2 PlasmaWave

Winix 5300-2

Winix 5300-2 is a cheaper alternative that offers very similar spec and design. Again similar to 5500-2, it also lacks the pre-filter that would help improve on the carbon filter efficiency.
Blueair 403 HepaSilent

Blueair 403

If money is no issue Blueair 403 is a good option with its Blueair-unique advanced filter. Again the pricing could be a big factor.


  • Consistent airflow delivery rate that covers large purifying area.
  • Pre-packed with 8 carbon filters.
  • 4-stage filtration including the additional pre-filter and PlasmaWave technology.
