Carole Smith
WINIX Compact 4 stage Air purifier

I love this air purifier. It arrived in no time at all. The air seems much cleaner/fresher and it also acts as a cooler on a hot day. Easy to use. Recommend.

Thanks for your review Carole!

These models are definitely easy to operate. You really don't want or need to have a bunch of usless bells and whistles when it comes to air purifiers. Just turn them on and let them do their job. That's the best way to go which is what these compact models definitely do.

Kind Regards
The Air Purifiers Direct Team!

LOVE this air purifier

Made a noticeable difference within 10 min of turning it on. Air smells cleaner, very quiet, nice looking design, easy to move between rooms. Very happy!

Thanks for the review Fay,

We agree with you! The Winix Compact 4 Stage air purifiers look great in just about every home space. But most importantly, they filter and clean your air effectively and efficiently.
We appreciate you taking the time to write a review and help others make an informed decision on what to buy.

Best Regards
The Air Purifiers Direct Team!


Don't know if it is making environment any healthier as yet but it seems to operate well. Only hear it when it picks up something to filter and fan turns up, red ring appears. Otherwise silent, would not know it is there. Sleep mode with light off is good.

Thanks for your review Pip!
The Compact model is definitely very quiet when running in sleep mode and one of the quietest out there for its size and price range.

Kind Regards
The Air Purifiers Direct Team!

Joanne McMahon
WINIX Compact 4-stage Air Purifier with Plasmawave

This is the first air purifier I have purchased and used. I am very impressed how well it works especially at night-it runs on the sleep mode which is whisper quiet and I feel I am sleeping better and wake up with an unblocked nose.
I was also impressed by the quick video on youtube showing how to unpack and put the filter in-much clearer that the included instructions.

Thanks for the review Joanne!

The sleep mode function is definitely a great feauture of the Winix range, which is why they are a great air purifier for bedrooms. We are happy to hear that you are benefiting from your new Winix air purifier already.

Kind Regards
The Air Purifiers Dircet Team!
