Winix C545 Review
The Winix brand is one of the most successful air purifier manufacturers in the industry.
That’s because Winix uses a patented PlasmaWave technology that can remove a wide range of harmful pollutants and odors from the air.
PlasmaWave technology is why so many people choose the Winix C545 and what makes it stand out among the competition.
The Winix C545 air purifier is also one of the only models that has an Energy Star certification.
That means that not only does this unit do a great job cleaning the air in your home, but it will also save you money on energy costs in the process.
Winix C545 Air Filter Types
The first part of our Winix C545 air purifier review will cover the air cleaning performance of this unit.
The Winix C545 uses a 4 stage air filtration system, which is a step above the previous Winix C535 air purifier (another popular model).
The filters included in this unit are the following:
- Pre-filter – The fine mesh pre-filter is in place to capture large contaminants, including hair, dust, and dirt particles. This is a permanent filter, so you can clean it over and over again without having to pay for a replacement.
- Activated Carbon Filter – This filter is in place to reduce indoor odors that come from cooking, pets, smoke, and office equipment. It also has the ability to remove harmful volatile organic compounds (VOCs) from the air, which are invisible toxins that most homes and offices contain.
- True HEPA Filter – This powerful filter captures microscopic pollutants that might be floating in your air. It traps 99.97% of particles down to 0.3 microns in size, including pollen, mold spores, allergens, bacteria, smoke, and pet dander.
- Winix PlasmaWave – This is a patented technology by Winix that enhances the air cleaning power of the air purifier. PlasmaWave uses natural water vapor to attack pollutants such as viruses, bacteria, germs, odors, and chemical gases. PlasmaWave is the safest way to break apart harmful pollutants to make the air around you safe and clean to breathe. No other brand includes it.

Winix C545 ACH Rating
It’s important to know the ACH rating of air purifiers because it lets you know how hard they work.
ACH stands for “Air Changes per Hour” and this number tells you how many times each hour an air purifier can exchange the volume of air.
The Winix C545 air purifier has a 4x ACH rating.
The Winix C545 4 stage air purifier can exchange the entire volume of air in a room up to 360 square feet four times every hour, or every 15 minutes.
The 4x ACH rating makes this a good air purifier for anyone who suffers from allergies or asthma since it cleans the air so efficiently.
Winix C545 CADR Rating
We’re not sure why, but many other Winix C545 air purifier reviews leave this section out.
But it’s an important one to cover.
The CADR rating of an air purifier lets you know how good it is at removing common pollutants from the air.
CADR stands for “Clean Air Delivery Rate” and it’s made up of three numbers for pollen, dust, and smoke.
The CADR rating comes from the Association of Home Appliance Manufacturers (AHAM) which is a third-party tester for air purifier manufacturers.
The Winix C545 has the following CADR ratings:
- Dust: 243
- Smoke: 232
- Pollen: 246
The higher the number, and the closer it is to the room size coverage, the more efficient the air purifier is at removing these harmful elements.
The Winix C545 4 stage air purifier with Wi-Fi and PlasmaWave technology meets the standards set by the AHAM, so you know it’s a highly efficient unit for cleaning indoor air.
