  • Unbeatable value for the price. The Winix PlasmaWave 5300 air purifier is low priced and has a lot of high end features such as a filter change indicator, air quality sensors, auto mode and sleep mode.
  • Large area coverage for its size. We were impressed the Winix PlasmaWave 5300 air purifier could cover a room up to 350 square feet and that’s a AHAM certified clean air delivery rate, so you know it is not overstated.
  • Simple, sleek design. The Winix PlasmaWave 5300 air purifier will easily fit in most rooms without being obtrusive or taking up too much space.
  • Good, efficient particle filtration for a medium to large sized room. Our testing results showed it removed 97% of particles larger than 0.3 microns on the first air pass.
  • Sleep mode makes it an ideal choice for a bedroom. The Winix PlasmaWave 5300 air purifier uses a smart light sensor to detect if s room is dark or light and when sleep mode is on and the room goes dark, the air purifier automatically adjust to the lowest fan speed for ultra quiet operation and dims the display lights to reduce light distraction as you try to fall asleep.
  • Energy Star Qualified. The Winix PlasmaWave 5300 air purifier requires a minimal amount of energy and it will not drive up your electricity bill.
  • Auto mode lets you set the Winix PlasmaWave 5300 air purifier and forget it. Auto mode monitors the air quality and adjusts the fan speeds accordingly to maintain fresh and clean indoor air.
  • Affordable to own. Only one filter cassette to replace once a year keeps the maintenance and replacement costs for the Winix PlasmaWave 5300 air purifier low. The replacement filter cassette includes 1 HEPA filter and 4 carbon pre-filters to provide 12 months of filtration (based on constant operation 24/7).
  • Filter change indicator let you get the most efficient use out of the HEPA filter.


  • Minimal odor removal. The Winix PlasmaWave 5300 air purifier’s carbon pre-filter has a minimal amount of carbon which is not enough to remove strong gases, chemicals and odors. Combined with the PlasmaWave&trade technology will help dissipate light household odors from cooking or cleaning.
  • Minimal warranty period: Winix only offers a 1 year limited warranty on the PlasmaWave 5300 true HEPA air purifier. This is shorter than the average manufacturer’s warranty on a product of this type, which we would expect to be at least 3 years. Despite its 1 year limited warranty we feel you can be confident this air purifier will last much longer.


The Winix PlasmaWave 5300 air purifier has an impressive room coverage of up to 350 sq. ft. and would be an ideal choice for a bedroom thanks to its quiet operation and sleep mode. It is good for someone who is looking for efficient removal of allergens and dust as well as light household gases and odors. With low energy use, auto-mode, air quality sensors and a filter change indicator all for under $200, the Winix PlasmaWave 5300 true HEPA air purifier is one of the best deals out there!
