Winix 5500-2

The Winix 5500-2 is another air purifier that will give you value for your money even if it only offers 4 stage air purification. The Winix 5500-2 features 3 different filters.  The first filter is a washable pre-filter, followed by a Carbon filter and finally a True HEPA filter.

The design aspects of air intake are almost similar with the Winix hr900 since the 5500-2 takes in air through the sides and the front openings, and clean air exits through the top.

The Winix 5500-2 has 4 modes, without a dedicated sleep mode option (The available option senses a darkened room and adjusts to quiet energy-efficient operation). With an output of approximately 250 Cubic feet of air per minute, the Winix 5500-2 is a decent air purifier and you should get it if you don’t mind the fact it is less advanced than its counterpart.

In this comparison, we get into an in-depth discussion on which air purifier you should buy and why. In the winix hr900 vs winix 5500-2, each of the two air purifiers comes with distinct features.

Other factors like price range, and features, of course, do come in handy as well.

What are the main differences and similarities between the Winix hr900 and 5500-2? Let us find out together, as we explore their special features, and why you should buy any of the two air purifiers for your indoor air cleaning experience.

With all that said, let us look into the details of the features, differences and similarities of the two air purifiers.

What are the main differences between the Winix hr900 vs 5500-2?

Maximum Airflow capacity

The airflow capacity is the rate at which an air purifier takes in air and cleans the air from its surrounding. The Winix hr900 leads the way having the highest air flow capacity of approximately 274 Cubic feet of air per minute while the Winix 5500-2 has an airflow capacity of approximately 250 Cubic feet of air per minute.

The higher the airflow capacity, the faster the cleaning speed and thus the lesser the time spent by the purifier in capturing air pollutants.

Air Purification process

The Winix hr900 has a 5-stage air purification process while the Winix 5500-2 has a 4-stage air purification process. Whereas the Winix hr900 comes with 2 prefilters (A washable and a replaceable prefilter), the Winix 5500-2 only has one prefilter (A washable fine mesh prefilter).

This difference gives the Winix hr900 an edge over the winix 5500-2 when you compare how they purify the air.

Remote Control

While some of the latest air purifiers come with remote monitoring capability, where you can turn it on and off via wireless connectivity with the help of an online application, both the Winix hr900 and 5500-2 have no wireless connectivity to support remote monitoring capabilities.

The difference, however, is that the Winix 5500-2 comes with a physical remote control device which the Winix hr900 doesn’t have. This remote control device has buttons and keys which help a user switch between modes, turn the device on and off, and also enjoy other controls.

The remote control device has been deemed by some users as not that useful since all the buttons and manual controls are found on the air purifier. However, the fact that the Winix 5500-2 has a physical remote control device makes it easier for you. This is because you do not have to always walk up to the device and switch modes.

Room square footage

For the Winix hr900, the largest room square footage it can cover is 300 sq. ft.  In contrast, the Winix 5500-2 can cover a larger room square footage of 360 sq. ft . The winix 5500-2 will do 5 clean air changes per hour in a 360 sq ft room.

Clean air delivery rate (CADR)

CADR determines the fraction of particles that have been removed from the air.  It is important to note that the higher the CADR, the faster the air purifier filters the air.

The Winix hr900 has a higher CADR of 264 cfm for dust, 301 cfm for pollen, and 258 cfm for the smoke while the Winix 5500-2 has a lower CADR, with 243 cfm for dust, 246 cfm for pollen, and 232 cfm for the smoke.

The Purchase Price

After comparing the 2 air purifiers with each other based on the features outlined above, normally a difference in how they are priced is expected. The Winix hr900 would usually be more expensive than the Winix 5500-2.
