Four Fan Speeds With Auto Mode

Winix 5500-2 comes with a four-speed. You can manually set the fan speeds low, medium, high, and turbo. The unit output is 250 CFM.

But when the air quality sensor feels the room air quality is poor, the air purifier automatically operates at a high-speed level to quickly clean the air. It means the air quality sensors measure and adjust the fan speed in real-time.

Air Quality Sensor and Indicator

This is the most advanced feature of the air purifiers. LED light on the control panel that changes on the base of real-time air quality. When the indicator light color is red, it means the air is highly polluted, and if the air quality is fair, that time LED light color is orange. The air quality sensor color becomes blue it means the air is completely clean and healthy for breathing. The air quality sensor automatically controls the fan speeds for cleaning the room air.

Sleep Mode

If you off the lights of your room or your room is darkened in, the air purifier automatically goes on sleeping mode. In sleeping mode, the air purifier works quietly and shuts down the control panel light To sleep comfortably. 


The timer is the so helpful feature of this air purifier. You can set the timer schedule 1 to 12 hours, and then the air purifier follows the Schedule time and automatically shut down on time.

Winix 5500-2 Filters

Three different types of air filters in Winix 5500-2 for room air cleaning.


Behind the front grill, you will see a washable pre-filter. The purpose of pre-filter to filter out larger particles so things like hairs, larger fibers, and all types of larger dust particles. 

A washable pre-filter is most important because a lot of units in the market have a replaceable pre-filter that means buying and costly. But the pre-filter of Winix 5500-2 is washable and cleanable. You just vacuum or wash every month, so it will work like a new pre-filter. 

True HEPA Filter

Winix 5500-2 have a True HEPA filter. The HEPA filter cleans particles that we can’t see with the naked eye. We usually need a microscope to see these tiny particles. And the size of these particles is 0.3 micron.

The HEPA filter cleans the different types of particles like allergens, dust, mold spores.

Carbon Filter

This unit comes equipped with an activated carbon filter. Many units in the market, especially at this price point down, come equipped with a fibrous filter simply coated with carbon.

The carbon filter inside of this Winix has a plastic honeycomb design, and inside of that plastic frame, there are activated carbon pellets when the air travels through here.

Suppose it contains any type of unwanted gas, a VOC or not, something like VOCs odors, molecules that make up those VOCs will bond to the carbon inside that filter and removed from the air.

Overall Performance

This unit has a CFM 2 watt ratio of 5 to 1 on its highest fan speed. And its ratio watts 10 to 1 on lower settings. You are getting a much better CFM to power draw ratio with this Winix unit. It is a very quiet machine for the amount of air that it processes. 

We like this machine because it is its value, which is probably what we like the most about this unit. Again you are paying about $150 here for a unit that outputs at approximately 250 CFM. It has that true HEPA filter. It has an activated carbon filter that is of a higher quality due to the fact. 

That it contains activated carbon pellets. You have that washable pre-filter. All of the features in this machine. You only have to pay 150 dollars for this air purifier, so in terms of value, this is one of the best affordable air purifiers out there in the market.

Our Recommendations:

If you compare Winix 5500-2 to the Coway AIRMEGA 400 is better than this. But the AIRMEGA 400 is so expansive and covers a large area like up to 1560 sq. ft. 

The AIRMEGA 400 motor warranty is just one year, and the electronic parts warranty is five years. On the other hand, Winix 5500-2 warranty is just one year. If you have a good budget, you will need to buy Coway AIRMEGA 400. 

This is the best air purifier for your home. Our strong recommendation for Winix 5500-2 this also the best product and Amazon’s choice. This air purifier comes with the best quality activated carbon filter, True HEPA filter, washable pre-filter, and plasma wave technology at this affordable price.


 What is the negative ion output?

Many individuals don’t comprehend this, but damaging ions lead to Ozone production considerably greater than exists even outside rain. 

Ozone, i.e., negative ion generation by air compressors, is revealed by an extensive investigation to be quite bad for people with respiratory difficulties, beginning with asthma and other worse states. Amounts can be rather high with use in closed interior surroundings and exacerbate respiratory ailments! 

California does not even permit the selling of purifiers that make Ozone! Do not be fooled by terms such as”plasma-wave,” etc., and recognize that lots of air purifiers won’t say the term Ozone.  

The negative ion, plasma wave, an attribute could be turned off or bypassed in several air compressors, and once I heard about this, I don’t use this feature in my Winix 5300. 

It’s possible to use the negative ion attribute on a few vacuums and application the attribute to close off and only ventilate your area for 2-3 hours to take out the Ozone until you return to the closed atmosphere. Not all pumps permit you to do so! Otherwise, the Winix does a fantastic job. However, respiratory sufferers remember!

Does the air purifier emit any odors like plastic odor? And how loud is it?

No odor, and you won’t hear any noise in the low sleep setting. It sounds like any fan does on the turbo setting. Mostly a wind sound, not a motor noise.

Can anyone help me decide between the Winix and the Honeywell?

I had a Honeywell (circular white one), not sure which unit. I needed to purchase separate filters bought separately costed me and was but cleaned the atmosphere rather nicely.

Rather I got the Winix 5300-2 that doesn’t have a distant nor washable filter (Winix 5500-2 does) but cleans efficiently nicely. 

Because I endure allergies and some other incoming fireplace burning smoke, and burnt cooking aromas make it difficult to breathe these functions fast. 

Winix replacement filter that I move thru every 5-7 weeks is well worth the characteristic of fresh breathing air.
