Are you wondering about which is best between the comparison of Winix c545 vs c555.  While both models offer many of the same features, there are some key differences that may help you decide which one is the best fit for your needs. In this article, we will take a closer look at these two models and see how they compare. By the end of this comparison, you should have a good idea of which one is right for you. Let’s get started!

Winix c545 vs c555: Key Differences

1. Air Purification System

The first major difference between the Winix c545 and the Winix c555 is the type of air purification system that each model uses. The c545 uses a 3-stage filtration system, while the c555 uses a 5-stage filtration system.

The 3-stage filtration system on the c545 includes a pre-filter, an activated carbon filter, and a true HEPA filter. This system is effective at removing large airborne allergens, smoke, dust, and pet dander from the air.

The 5-stage filtration system on the c555 adds two additional filters to the mix: a washable pre-filter and a plasma wave technology filter. These additional filters help to remove smaller airborne allergens, bacteria, and viruses from the air.

2. Clean Air Delivery Rate (CADR)

Another important difference to consider is the clean air delivery rate (CADR) of each model. The CADR is a measure of an air purifier’s ability to clean the air in a room. The c545 has a CADR of 240 m3/h, while the c555 has a slightly higher CADR of 250 m3/h. This means that the c555 will be able to clean the air in a room slightly faster than the c545.

3. Noise Level

The noise level is another important consideration when choosing an air purifier. The c545 has a noise level of 50 dB, while the c555 has a noise level of 53 dB. This means that the c545 will be slightly quieter than the c555.

4. Power Consumption

The final difference to consider is the power consumption of each model. The c545 has a power consumption of 60 watts, while the c555 has a power consumption of 65 watts. This means that the c545 will be slightly more energy-efficient than the c555.
