What Are Winix Air Purifiers (what makes them unique)?

And what makes them unique? Great question!

Winix started as a South Korean company by another name (Yooshin Enterprise) in 1973. The company later changed its name to Winix and moved to the US in the early 2000s.

Winix is a very well-regarded air purifier brand and is known for its extremely high quality standards.

The company’s stated objective is to “develop clean and healthy living and working environments by creating the highest quality of clean air and clean drinking water that you can make yourself!”

They’re also well known for their elegant designs, and have won awards in that area including the including the Reddot design award and the IF design award.

Something that makes Winix unique compared to other air purifier manufacturers is their PlasmaWave technology. This is a type of ion filter that combines with the True HEPA filter (more on that below) and activated carbon filter to ensure the air you breathe is of the highest quality.


What Do You Look for In the Best Winix Air Purifier?

So, you like the Winix brand, but aren’t sure what else to think about before buying? Let’s take a look!

First, you want to ask yourself what it is exactly that you want to remove from the air – is it mostly particles (such as dust, pollen, etc.) or odors / gases, like tobacco smoke?

If it’s particles, you’ll want to be sure you select a purifier with a high Minimum Efficiency Reporting Value (“MERV”). That’s the standard measure of how well a particle air filter works.

Air purifiers with the highest MERVs earn the designation of “True HEPA” filter (“HEPA” stands for “High Efficiency Particle Air [filter]”. The good news is that all Winix air purifiers reviewed below come with HEPA filters.

If you’re more concerned with removing odors, you’ll want to be sure the model you select has an activated charcoal (also called “activated carbon”) filter.

Do you have pets?

Pet fur and dander can really shorten the life of a filter (which then needs replaced), so finding a unit with a pre-filter (ideally a reusable pre-filter) can help keep the True HEPA filter in good shape for longer (see our third Winix recommendation below).

How large is the room / area where you’ll put the air purifier?

Air purifiers, including those made by Winix, are measured by their CADR (“Clean Air Delivery Rate”), which tells you how many cubic feet per minute (“CFM”) the air purifier can process. T

ake a look at the below table from the EPA which compares square footage and CFM.
