Design & Size Comparison of Winix HR900 Versus Winix 5500-2
Now, let’s take a look at the design and size of each product.
The Winix HR900 air purifier’s design is exceptionally sophisticated and distinct from other Winix purifiers.
The Winix HR900’s revolutionary design enables your air purifier to draw in as much contaminated indoor air as possible. This is done not just through the front grill but also the bottom and sides.
A perforated grill and wicking filter are what make this air purifier special. Only the HR900 has a grill of this sophisticated caliber.
The Winix HR900 is approximately 23.6 inches tall and 9.6 inches broad. All other Winix air purifiers fall into the low-end price range. For the air purifier to stand its ground, it keeps it steady and sturdy.
Winix 5500-2 With an Activated Carbon Filter
The Winix 5500-2 is a well-designed air purifier available only in black with a plastic exterior. Nonetheless, it appears to be something other than a low-cost air cleaner.
This Winix 5500-2’s top exit air vent is comparable to that of more traditional air purifiers like the Coway AP- 1512HH. If we discuss the Winix 5500-2’s weight and height, we can claim that it is comparable to the Winix HR900.
Both the Winix 5500-2 and Winix HR900 include two side-mounted handles. These handles make it easier to transport the air purifier throughout your home.
Standard Features of Winix 5500-2 & Winix HR900
The most important component of an air purifier is its features. The Winix 5500-2 & Winix HR900 virtually have the same features.
1. Quality Indicator
The sophisticated air quality indicator is the most important component of these purifiers. The indicator measures indoor air quality and uses LED light colors to display and show you a report.
2. Auto Mode
The auto mode, which operates in conjunction with the air quality sensor, is the second common feature of these purifiers. When the quality of air in the room is low, the mode automatically increases the fan speeds to clean the air quickly with the help of a true HEPA filter.
3. Sleep Mode
These air purifiers feature a sleep mode activated in a darkened room. Both the Winix HR900 and the 5500-2 control panels include a timer button that allows you to set the time at which you would like the device to switch modes.
4. Carbon Filter Lifespan Indicator
There is also a carbon filter lifespan indicator. It reminds you to change the filters when they are worn out.

CDR & ACH Comparison of Winix HR900 vs Winix 5500-2
In addition to the recommended room coverage of 360 sq ft, the Association of Home Appliances Manufacturers (AHAM) has standardized the performance of air purifiers by determining the Clean Air Delivery Rate (CADR).
The CADR is based on how much air can be purified over time. This means that the higher the CADR rating, the better it can filter air and eliminate chemical vapors that could cause nasal congestion.
In filter comparison, the Winix 5500-2 has a four-stage filtration technology that includes a pre-filter, an activated carbon filter, a True HEPA filter, and PlasmaWave technology. The HR900, on the other hand, has a 5-stage air purification system.
Overall, the Winix HR900 has a higher CADR of 258 cubic feet per minute for cigarette smoke, 264 cubic feet per minute for dust particles, and 301 cubic feet per minute for pet hair.
An additional smart sensor gives the HR900 an edge over the 5500-2. The HR900 has three intelligent sensors that can detect the air around them and instantly modify the fan speed.
The Winix HR900 has a 5-stage air purification system, PlasmaWave technology, and a specialized Ultimate Pet Pre Filter that offers extensive control of visible pet dander while extending the lifetime of the other activated carbon filter.
Even while the Winix 5500-2 can filter larger rooms than the HR900, it has a lower CADR. The CADR for the 5500-2 is 243 cubic feet per minute for dust mites, 246 cubic feet per minute for pollen, and 232 cubic feet per minute for smoke.
Despite having dual smart sensors, the 5500-2 can detect and change the fan speeds less effectively.
