Winix 5500-2 Review Filters

Winix 5500-2 Filter Types

The Winix 5500-2 has an impressive 3-Stage Air Filtration System.

The filters included in this process are:

  • AOC Carbon Filter – While many air purifiers have carbon filters, the one in the Winix 5500-2 is more advanced and washable. The AOC Carbon Filter in this device is a thick, honeycombed filter that’s placed between two mesh sheets. Within the honeycombs are thousands of activated carbon granules. As air passes through it, odor particles are caught and trapped; leaving your home smelling fresh. The fact that it’s washable means you can use it over and over again without paying for a replacement.
  • True HEPA Filter – The Winix 5500-2 removes 99.97% of pollutants as small as 0.3 microns in size with the highest-quality True HEPA filter. This means that it can trap ultrafine dust, allergens, pet dander, and many bacteria particles. This air purifier keeps your air clean, prevents the spread of illness, and reduces allergy symptoms.
  • PlasmaWave – If anything happens to get past the AOC Carbon Filter or True HEPA Filter, the PlasmaWave technology will stop it. This technology further reduces the number of harmful elements in your air, including microscopic bacteria, viruses, and volatile organic compounds (often referred to as VOCs).

Winix 5500-2 Air Purifier Review of CADR and ACH Ratings

CADR Rating

To prove that their air purifiers are the best, many manufacturers have their machines tested by the Association of Home Appliance Manufacturers (AHAM) to get a Clean Air Delivery Rate Rating (CADR).

The results of these tests let customers know how well the appliance can filter out pollen, tobacco smoke, and dust.

If the air purifier has at least a 2/3 rating for each number when compared to how many square feet it covers, it’s considered to be highly efficient.

Winix 5500-2 CADR Rating:

  • Dust: 243
  • Smoke: 232
  • Pollen: 246

As you can see, this Winix 5500-2 True HEPA air purifier with PlasmaWave meets or exceeds the standard set by the AHAM.

Additionally in this Winix 5500-2 review, we wanted to point out that this air purifier can rank in the same category as more expensive machines in terms of efficiency.
It’s also a very cost-effective device for improving the indoor air quality of your home without using a lot of energy or having high filter replacement costs.

Winix 5500-2 ACH Rating

The length of time it takes an air purifier to exchange the full volume of air inside a room is referred to as the Air Changers per Hour (ACH) rating.

This Winix 5500-2 air purifier has a 4X ACH rating.

This means that each hour that passes by, the air in a room up to 360 sq. ft. is exchanged four times.

A 4X ACH rating is the minimum rating you want to see for an air purifier if you have any sort of allergies or asthma.
