Winix PlasmaWave 5300 Air Cleaner Review

The Winix WAC5300 is a great air cleaner for rooms up to 350 square feet (32.5m2) and costs between $130 and $180. Excellent price for such size space. The Winix WAC5300 contains a 99.97% efficient True-HEPA Filter, Odor Control Carbon Pre-Filters, and PlasmaWave Technology.Winix PlasmaWave 5300 Air Cleaner Model


  • Quiet on low setting – good for sleep.
  • Excellent value for the price. The Winix PlasmaWave 5300 air purifier is low priced and has many high-end features such as a filter change indicator, air quality sensors, auto mode, and sleep mode.
  • It does not produce ozone; it removes it.
  • Energy star qualified.
  • High CADR ratings.


  • Annoying electric whizzing when the PlasmaWave feature is enabled. And the sad thing is that it is enabled all the time – you can’t turn it off.

Winix PlasmaWave 5300 Design, size, placement

The Winix Plasmawave 5300 air purifier is medium size. Height is 21.7 inches (55cm), width 19.i in (48.5cm) and depth is 8.5in (21.5cm). Depth is narrow, so air purifiers will easily fit in smaller places. You can put it close to the walls because the air outlet is at the unit’s top.

The air purifier has an attractive and lightweight, sleek design, metallic silver color. Weight is 15lbs (6.8kg). Unfortunately, there is no handle to carry it from room to room.

Type, How it works, and what sources of indoor pollution destroy

The Winix 5300 has a motor and a fan that moves dirty air through filters. Filters purify the air.

This model has 3-stage air cleaning.

First is a carbon pre-filter to capture offensive household odors caused by pets, smoke, cooking, and many other odors found within your home. This filter is also coated with CleanCel to neutralize germs and bacteria upon contact and extend the life of your True-HEPA filter.

The second is true-HEPA filtration by capturing 99.97% of airborne pollutants as small as 0.3 microns, like allergens, pollen, mold, dust, etc.

The final stage is PlamaWave technology that attacks pollutants at the molecular level to neutralize viruses, bacteria, chemical vapors, odors, and harmful gasses in the air, without producing harmful ozone.

Winix PlasmaWave 5300 Features

  • On top of the unit is ergonomic electronic controls. The biggest is the power button. Next to it is the speed/mode button –  you can change between auto and sleep mode.
  • 4 speeds – low, medium, high, and turbo.
  • The filter replacement indicator will illuminate when to replace the true-HEPA filter.
  • The air quality indicator shows the current level of air quality in your room.
  • The air quality sensor automatically monitors the air quality level and adjusts the fan speed accordingly.
  • Energy star qualified

Winix PlasmaWave 5300 Noise level

As with other air purifiers – loud at the highest speed and quiet on low.

The Winix PlasmaWave 5300 air purifier uses a smart light sensor to detect if s room is dark or light and when the sleep mode is on. The room goes dark, the air purifier automatically adjusts to the lowest fan speed for ultra-quiet operation and dims the display lights to reduce light distraction as you try to fall asleep.

Winix PlasmaWave 5300 CADR

  • Dust value – 248
  • Pollen value – 251
  • Smoke value – 235

Recommended max for 350 square feet. Ceiling height 8 feet.

350×8=2800 cubic feet.

  • Dust 2800/248 = 11 minutes
  • Pollen 2800/251 = 11 minutes
  • Smoke 2800/235 = 12 minutes

The time needed to cover all air in 350 square feet room. Excellent result.

Winix PlasmaWave 5300 Maintenance and upkeep

Winix air cleaner is simple to maintain.

The carbon pre-filter should be replaced every 3 months—4-pack costs around $40.

Replace the true-HEPA filter when the indicator light turns on. Under normal use, the HEPA filter should last 12 months, depending on air quality. It costs around $70.

Winix 5300 uses only 6 watts on speed 1 and 90 watts on turbo speed. But turbo speed is rarely used. Most of the time, you will use the first 3 settings, and they are economical.

Winix PlasmaWave 5300 Summary

The Winix PlasmaWave 5300, in my eyes, has proven that it is an excellent air purifier. Price is affordable, covers space up to 350 square feet. Great digital controls with filter replacement indicator, auto mode, sleep mode, air quality indicator, and air quality sensor.

But the sad thing is that you can’t turn off the PlasmaWave function. I would suggest to pay $30 more and buy Winix 5500. It has a remote control and with it can turn on/off PlasmaWave function.
It covers the same space. Plus the main filter in it can be washed instead of replacing it. That’s something like a $60/year savings so it will pay for itself if it lasts a few years.
