Winix 6300-2 Air Purifier

Winix 6300-2 is an advanced model of Winix 6300. With a slight increment in its price, this model provides better features and specifications. Some of them are described below:

Smart Sensors

The Winix 6300-2 air purifier comes with a smart sensor that detects the air quality around you efficiently. The indicator shows blue color when the air quality is good, orange-yellow for fair and red color pops up when it is poor and harmful for breathing.

Carbon Filters

It comes with 8 carbon filters that guarantee the complete filtration of contaminants, smoke, allergens, and other irritants present in the air.


The Winix 6300-2 comes with a warranty of 1 year.

4 Stage Filtration Process

Both 5500-2 and 6300-2 have 4 stages of filtration. First, the polluted air goes through the pre-filters to the AOC carbon filters and Hepa filters. This air is further purified through the PlasmaWave technology which is an ultimate killer of microbial organisms and a great purifier of air.


It comes with a pre-filter that captures contaminants like pollens, pet hair, dust, and microbes making sure that the air you breathe in is completely pure. This pre-filter is attached with AOC (Activated Carbon Filters) which reduces odors and provides protection with VOCs. The main quality of this pre-filter is that it is washable which increases the lifespan of the HEPA filter by 12 months, proving it to be a perfect choice.

True HEPA Filter

The 6300-2 and 5500-2 work in conjunction with the True HEPA filter which is best known to remove 99.97% of allergens, viruses, and molds, even smaller than 0.2 microns. The only drawback is that the True HEPA filter is unwashable.

PlasmaWave Technology

PlasmaWave technology acts as a permanent filter that safely breaks chemical vapors, smoke, and other pollutants with no emission of harmful ozone. It acts as an ionizer and can be switched on/off with a button. Over time, this technology was frowned upon by the customers because of the ozone production however, the company ensures a safe level of ozone release.

During our research, we found that almost all of the customers were satisfied by the overall working of the 6300-2 Winix air purifier and praised it for its quietness and ability to purify the air to a noticeable level.

The two main complaints received were, its inability to connect with Wifi and the frequent need to change the filters with new ones after every 3 months claiming them to be a high maintenance device as the new filters were quite expensive.

However, during our testing, the only complaint we found was that the air quality sensors are only great at detecting strong odors such as perfumes and mosquito repellants and ignoring weak smells. Otherwise, it has met our expectations completely.

  • Requires power output of only 70W.
  • Produces noise of only 28dB, lower than the sound of a whisper.
