Winix c555 Review: Comprehensive analysis

Winix C555 Air Purifier Review

There are plenty of reasons why we fell in love with the Winix c555 air cleaner with plasmawave technology.

Take a look:

Winix C555 Air Cleaner with Plasmawave Technology Construction and Design

I was first won over by the design and mostly because air leaves through the top- I find it more effective.

Plus, as you would expect, it’s certainly well-built and you can notice the quality right off the bat.

Then, it’s the same size as c535- 14.9 W x 7.8 L x 23.6 H – so it’s not that big.

Portable units are supposed to be lighter and this weighs a manageable 17.6 lbs hence you won’t strain to move it (The installed handgrip comes in handy).

But you should note something:

Even though it fits on myriad tops/places, always place it on flat, hard surfaces (not slanted) to enhance its stability.  

Winix c555: Performance and operation

This unit uses the classic 5-stage filtration process and the results will delight you.

Here is how it runs:

Air first flows through the fine mesh pre-filter where large particles such as hair, carpet fibers, and dust are captured.

The true HEPA filter then takes over and will trap pet dander and a host of allergens (as fine as 0.3 microns).

Next, the anti-microbial coating (on the HEPA filter) cleans dangerous bacteria from the air, dramatically lowering your risk of contracting infections.

Your purifier then works on offensive fumes, smoke, and other nasty odors lurking in the air- the activated carbon filter expertly does the job.

This filter helps sustains optimum air quality as long as you wash it every 3 months (no replacement needed).

In the last stage, the exclusive Plasmawave ionizer breaks down the molecular structure of the last batch of surviving pollutants to supply the healthiest air you can imagine.

You also enjoy maximum airflow- the fan (with 4 speeds) is quite powerful- and very little noise (54.8 dB at the highest turbo setting).

In fact, it’s mostly white noise at night.

Besides, the Winix c555 air cleaner with plasmawave technology dims the lights to help you sleep (auto mode).

You can set everything manually- using the straightforward control panel or remote control – or leave it on the aforementioned auto mode.

Here, the intelligent sensor will help it adjust its speed to match the pollution level indoors.

The one downside is the pricey Winix c555 replacement filter and it’s not packed with extra filters like the c535.

Overall, a very solid unit. 

Winix c555: Power ratings and comparative energy efficiency

Now, Winix air purifiers have not always been the most energy-efficient but it seems the company is catching up, if this unit’s energy consumption is anything to go by.

It draws 65 watts (at maximum fan speed), which is slightly lower than Winix c535 and Winix 5500-2 air purifiers (70 watts).

Plus, its energy star certified.

If you’re a fan of Winix products, you know what that means: some savings on your energy bills, at last.

Winix c555: Room capacity

The C555 delivers the best results if you use in to clean bacteria, viruses, dust, mold, and other elements in bedrooms, offices, living rooms, and kitchens sized up to 360 sq.ft.

You alternatives (for rooms such size) are the Coway AP-1512hh (361sq. ft), Winix 5500-2 (360 sq ft), Winix c535 (360 sq. ft), and Honeywell HPA300 (464 sq. ft).

Its CADR ratings are as follows:

  • Smoke-232 cfm
  • Pollen- 246 cfm
  • Dust-243 cfm

It refreshes the air in your rooms 4 times per hour. 

Winix c555: Warranty and support

The Winix c555 air cleaner comes with a two (2) years limited warranty, same as the Winix c535 air purifier.

Some of its competitors, however, carry a longer warranty.

For instance, the Coway AP-1512hh carries a 3-year warranty while the Honeywell HPA300 comes with a 5-year warranty.

On the issue of support, the Winix dedicated call center team is very responsive and is quick to answer your questions.

The call center number is (877) 699-4649. 

What I like about the product

  • Very low noise levels
  • Very easy to use
  • Works very well

What I don’t like about the product

  • A bit heavy
  • Pricier than C535

Winix C555 Review Conclusion

The Winix c555 air purifier looks like a timely upgrade on the C535 and could make all the difference in living rooms, bedrooms, and kitchens.

The auto function, digital display, and nice remote all make it quite useful.

It’s not too big, has a pretty design, and the fan runs quietly.

It can be a worthwhile investment.
