Winix C555 Vs C545 – Which Air Purifier is better?

If you’re in the market for an air purifier, you may be wondering whether the Winix C555 or C545 is the better option. Both are excellent choices, but there are some key differences to consider. The C555 is a bit more powerful, with a CADR of 243 versus the C545’s 232.

It also has a higher maximum room size of 700 square feet versus the C545’s 500.

If you’re in the market for an air purifier, you may be wondering which one to choose. The Winix C555 and the C545 are both great options. But which one is right for you?

The C555 is a top-of-the-line air purifier with many features. It has a True HEPA filter, which captures 99.97% of airborne pollutants as small as 0.3 microns. It also has a carbon filter to absorb odors, and a washable pre-filter to capture larger particles.

The C555 is ideal for large rooms up to 350 square feet and includes a remote control for convenience. The C545 is also a great air purifier, but it doesn’t have all the bells and whistles of the C555. It has a True HEPA filter, but it only captures 99.95% of airborne pollutants as small as 0.3 microns.

It doesn’t have a carbon filter or a washable pre-filter, so it’s not quite as effective at capturing odor and larger particles. However, it’s still a great option for smaller rooms up to 250 square feet and includes an automatic sensor that adjusts the fan speed based on air quality levels. So, which one should you choose?

If you have allergies or are sensitive to airborne pollutants, the C555 is the better option because of its more powerful filtration system.

But if you’re looking for a high-quality air purifier that will do a great job of cleaning the air in your home, then you may want to take a closer look at the Winix C555 and the Winix C535. Both of these air purifiers are designed to remove pollutants from the air, but there are some key differences between them that you should be aware of before making your final decision.

The Winix C555 is a higher-end model that features a 3-stage filtration system. This system includes a pre-filter, an activated carbon filter, and a True HEPA filter. This combination of filters does an excellent job of removing contaminants from the air, including dust, pollen, smoke, and pet dander.

The C555 also features an automatic filter replacement indicator so you always know when it’s time to replace the filters. The Winix C535 is also a very effective air purifier, but it uses a 2-stage filtration system instead of 3 stages. This means that it doesn’t include the True HEPA filter found in the C555.

However, it does feature an activated carbon filter and a pre-filter which work together to remove many common airborne pollutants. The C535 also has an automatic filter replacement indicator so you won’t have to worry about forgetting to replace the filters on time. So which one should you choose?

If you’re looking for the absolute best possible performance, then go with the Winix C555.

Winix C555 Vs C545


Is the Winix C535 the Same As the C545?

The Winix C535 and C545 are very similar air purifiers. Both have the same CADR ratings for smoke, dust, and pollen. They also have the same filter life indicator and replacement filter indicator.

The main difference between the two models is that the C535 has a manual fan speed control while the C545 has an automatic fan speed control.

How Long Do Winix C545 Filters Last?

The answer to this question really depends on how often the filter is used and how well it is taken care of. A Winix C545 filter can last anywhere from 6 to 12 months before it needs to be replaced. Of course, if the filter is used more frequently, it will need to be replaced more often.

If it is taken care of properly and not overused, it can last up to a year.

What is Sleep Mode on Winix C545?

Assuming you are referring to the Winix C545 Air Purifier, sleep mode is a feature that allows the unit to operate at a quieter, lower speed setting when it is dark in the room. This can be helpful for people who are sensitive to noise or who want to keep the unit running overnight without disturbing their sleep. The C545 also has an auto-off timer that can be set for 1, 4, 8, or 12 hours, so it will automatically turn off after a certain amount of time if desired.

Should I Leave My Winix Air Purifier on All the Time?

When it comes to operating a winix air purifier, the general rule of thumb is to leave it on as much as possible. There are a few reasons for this. First, leaving the unit on ensures that the filter has enough time to properly cleanse the air in your home.

Second, it allows for more consistent air quality throughout your home since the unit will be able to capture pollutants more effectively when left on for extended periods of time. With that said, there are also a few instances where you may want to turn off your winix air purifier. If you know that you’ll be away from home for an extended period of time (e.g., going on vacation), then there’s no need to keep the unit running while you’re gone.

Additionally, if your power goes out or if there’s another issue with the unit itself, then you’ll obviously need to turn it off until the problem can be resolved. Overall, though, it’s generally best to leave your winix air purifier on whenever possible in order to ensure optimal air quality in your home.
