Arguably the only difference you can tell between Winix 6300 and 5500 which might not be a bad thing. With the additional filtration, Winix 6300 5-stage purification starts off with the combined Carbon pre-filter that remove large particles such as hair, dust plus gases and household odors. The Sanitized® anti-microbial treatment serve as an extra layer protection on the carbon pre-filter that discourages micro-organism growth on it. Thirdly, the True-HEPA filter would trap any airborne pollutants with an effective rate of 99.97% in removing particles as small as 0.3 microns. Last but not least, Winix own PlasmaWave would work at a molecular level to safely breaks down odors, allergens, chemical vapors, and other indoor pollutants without emitting harmful ozone or byproducts.

It is very effective on common airborne pollutants notably dust, pet hair. Nonetheless against small scale pollutants, Winix 6300 52 - 222 cfm 4 speed airflow delivery rate + True HEPA filter is fine at clearing away mold, spores, mildew, pollen, germs, dust mites and pet dander.  On odors, smokes and fumes, Winix 6300 filtration is weak in tackling cooking odors, radon, ammonia chemicals, VOCs, tobacco and cigarette smokes.

Keep it down

Power consumption
5 - 90 W
Winix 6300 5 - 90 W power consumption is justifiable and 26.6 - 60+ dB noise level is pretty decent, not too intrusive that would disturb your sleep. At low to medium speed, there is only a bare humming sound while at high/ turbo speed, a clear audible noise which is typical in most air purifier. Winix 6300 is ENERGY Star rated so it should consume less energy thus you would save more on electricity bills. Basically expect the same noise and consumption level as Winix 5300/ 5500.

^ Winix 6300 replacement filters estimated cost
Winix 6300 pricing might not be its strong suit due to the additional filtration and limited stock availability (replacement model is out). Filter replacement cost is reasonable as it comes in bundled pack and used the same package as Winix 5300. Keep in mind that you would have to change the Carbon filters every 3 months while HEPA filter would last through a year depending on the air quality. For more great Winix 6300 deal, visit Amazon as it has the fastest shipping time, attractive price tag with discount and simple return policy.

The challengers

Winix 6300-2 PlasmaWave

Winix 6300-2

Winix 6300-2 is the latest version that see a bump in spec and purifying capacities. The main disadvantage though is the price tag and the stock availability.
Winix 5500 Plasmawave

Winix 5500

Winix 5500 in our humble opinion the better option with very similar spec at a much cheaper price tag. The only thing its lack of it’s the Sanitized anti-microbial treatment which isn’t too much to give in.
Blueair 450E HepaSilent Digital Air Purification

Blueair 450E

Blueair 450e is another great option that shines on its purifying coverage and filtration but you have to top up even more for the extra goods.

In conclusion......

  • 5-stage filtration (with Sanitized® anti-microbial treatment and PlasmaWave) .
  • Decent pricing with good coverage and airflow performance.
  • True HEPA filter that is highly capable of capturing small irritant particles.
  • Effective Odor carbon filter with sanitized antimicrobial that prevent the growth of micro-organism on the pre-filter.
  • Remote control that could control fanspeed and turn PlasmaWave on/ off.
  • 4 fanspeed with Auto/ sleep mode that depends on the smart sensor.
  • The combination of pre-filter and odor control filter tend to be less effective than stand-alone filter.
  • Only 1 year warranty compared with Winix FresHome series that comes with 3 years warranty.
  • Hassle to change the Odor carbon filter with only 3 month lifespan as oppose to the 1 year True-HEPA lifespan.
  • As mentioned, timer would be useful to let the air purifier run through the night.
