Three-Stage Air Purification

This air purification system from Winix is fitted with an activated carbon filter, a HEPA filter, and PlasmaWave System. The combination of all three makes it an excellent unit for filtering and purifying your indoor air.

For a start, the activated carbon layer – Advanced Odor Control (AOC) – filter filters your dirty air. While most units on the market feature an activated carbon filter, the one on this unit features an advanced design.

Most air purification units use flexible, thin carbon filters that look like your average rough dish scrubber. The AOC filter on this unit features a honeycomb design that is placed between mesh sheets.

The honeycombs contain thousands of pure activated carbon beads. This means that the AOC filter on the 5500-2 utilizes more carbon than an average filter – the result is noticeably better air quality when compared with other units.

Once the AOC filter removes the bad odors, air passes through the High-Efficiency Particulate Air (HEPA) filter. This is where 99.97 percent of particles bigger than 0.3 microns are trapped; for instance, dust, bacteria and pet dander – no more allergies!

The last stage is the PlasmaWave filter. The PlasmaWave technology releases hydroxyls into the filtered air.

Hydroxyls are naturally occurring elements found in outdoor air, and they are used for killing odors by eliminating viruses, bacteria, and Volatile Organic Compounds (VOCs). This Winix 5500-2 Air Purifier system replicates this process inside your home by releasing these hydroxyls.

Low Noise Levels and Power Consumption

The 5500-2’s sealed and sturdy body framework does an exceptional job of reducing noise. At 26.6 to 60+ dB noise level, this unit is quiet at low to medium speeds, and average at high-speed setting.

In addition, this PlasmaWave unit saves you a substantial amount when it comes to your electricity bills if you will be using it on a constant basis. The unit’s power usage is minimal at low fan speeds and average at max fan speed settings.

Offers Protection Against Multiple Elements

This unit is capable of getting rid of viruses, bacteria, allergens, and irritants in your indoor area. It’s also quite efficient in getting rid of more prominent airborne pollutants like dust and hair.

The unit offers acceptable performance in cleaning out pet dander, dust mites, pollen, mildew, and mold. Fire, chemical, cooking odors, tobacco smokes, vapor, radon, and cigarette odors don’t stand a chance against this Winix model.

Easy Maintenance and Care

It’s critical that you carry out regular maintenance of any air purifier to get rid of clogs in the air ventilation. However, the design of this Winix PlasmaWave unit makes maintenance effortless.

Smooth front polyester plastic makes it simple to clean and get rid of any stains and dust. In addition, the intake- and outtake air ventilation system is easy to take care of with a simple gentle sweep and brush.

Who can use it? Anyone in need of the cleanest indoor air from a unit that takes giving you fresh air seriously.
