Design and size:

Next, in this Winix air purifier C545 review, let’s get into this device’s build quality and overall design. Most of the external components of this air purifier are hard plastic, and there’s nothing to worry about that. Most air purifiers within this range use hard plastic as a way of putting the cost down. All in all, the Winix filter C545 looks and feels well-made and has no loose parts that would otherwise raise suspicion. For the uninitiated, Winix air purifiers are likely to have perforated holes for air intake in recent years because it was quite literally more efficient to trap large dust before it contacts with the pre-filter. Winix C545 still runs the bottom-to-top airflow system concept, with an air outlet on top. The Winix C545 4-stage air purifier comes in white, so it will match any colour scheme or décor you have in your home.


Pre-filter – The polluted air must pass through a fine mesh pre-filter. This pre-filter will help capture the large objects of contaminants, such as pet hair and even some kinds of pet dander and skin. It captures large air contaminants such as pet hair, dust, and lint from your fabrics. This pre-filter can be vacuumed or even washed to increase its efficiency.

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. In your home, these contaminants include Volatile Organic Compounds (VOCs), gases, and odors from your kitchen and pets.

True HEPA Filter – This powerful filter captures microscopic pollutants that might be floating in your air. The third Winix air purifier c545 filter is a true HEPA filter. We’ve written a complete guide on everything you need to know about True HEPA filters in this guide. For the sake of this post, just know that HEPA is an acronym for High-Efficiency Particulate Air, and it refers to a filter that is certified to block up to 99.97% of contaminants that measure 0.3 microns. 

Winix PlasmaWave – This is a patented technology by Winix that enhances the air cleaning power of the air purifier. PlasmaWave uses natural water vapour to attack pollutants such as viruses, bacteria, germs, odors, and chemical gases. The True HEPA filter and PlasmaWave technology work perfectly fine to capture all airborne pollutants. We all know of the Winix PlasmaWave, a technology that releases both negative and positive ions to form hydroxyls that attack airborne contaminants such as viruses, bacteria, germs, odors, and chemical gases (VOCs).
