Pollutant Reduction

Levoit Core 400S
I bought a Levoit Core 400S for Mother's Day and just set it up. My mom has been having bad allergies and sometimes has coughing fits, so I thought it could help with that. But apparently our PM2.5 is already very good (5 when I turned it on, then dropped to 1-2 after a while). We don't have any pets and clean the house once a month.

Winix Zero S Air Purifier
Very good all round, good value
This is my favourite of the 3 winix and 1 levoit air purifiers I've owned. The pellet-based carbon filter has lasted longer and worked better at reducing odors than the foam versions, and is washable. The energy efficiency and quietness is great on the lower speeds, while still moving enough air to ...

Allergy Relief

Levoit Core 400S
Great job for those w. breathing problems
Wife has COPD/Asthma. No, this is not a cureall, but we live in central TX, home of the famous "Texas Allergens" - Nothing cures COPD but she was having some real trouble and this really seemed to help in the bedroom. GOOD - First of course, is the little blurb above. Others. They advertise the fan ...

Winix Zero S Air Purifier
Great Product
The sleep mode is silent. It still does the job, but with my dust allergies I prefer to have it on a bit more powerful during the night. So I have it on setting 2 or 3. Setting 4s sound is not noticeable during the day but at night its probably too loud to sleep with on the full power. But even with...

Allergens

Levoit Core 400S
Either defective or pointless
I smoked a cigarette and blew it at this and it didn't go up from "5". When I moved it inside, it just blew cigarette smelling air into my room. Right there I knew I was most likely returning this product. The entire time I had it it would just randomly go from 5 to 1... my allergies were the exact ...

Winix Zero S Air Purifier
The blue light of joy.
This is a sturdy unit without being unattractive for a living room. It seems to do what it is intended to do. The power rating is 65 Watts, but mostly it should be running at a lower power than this, particularly when it goes into the automatic sleep mode once the light sensor is triggered by darkne...

Ease Of Use

Levoit Core 400S
Outstanding device, smart app wants too much phone access
The noise level is pretty quite for the amount of air it moves. It is pretty big, but not heavy enough to be difficult to move. Does a great job filtering the air. I liked it so much I bought a second one a few days later for my mom when she complained about her allergies. When you unpack it, make s...

Winix Zero S Air Purifier
Owned for 2 days - thinking of buying another
Owned for only 2 days so make of my review what you will. Appearance is cosmetically pleasing. Looks modern, high tech, and fits in well with my decor, furnishings etc. Noise is whisper quiet. On Auto the air quality it senses in my house is blue for good. So the fan hasnt kicked in above 2. I barel...

Effectiveness

Levoit Core 400S
So far so good!
I have owned this product for less than 24 hours as of this writing. More updates as I have more to say/remember to do them. Also, I will be very verbose, the sort of in-depth information I want when I am researching products over $99 for purchase, so you really know what's going on. Hopefully it he...

Filter Replacement

Levoit Core 400S
Lighter than other Levoit large room Air Purifiers BUT be careful of the bottom of this thing.
First off I have two large room Levoit Air Purifiers and I've used them for a few years. They work good when the filters are clean but not so good when they are bad. The lights don't turn off on the so I had to put gaff tape on them for night as it bugs me. The older ones are easy to change filters ...

Winix Zero S Air Purifier
Super quiet. Keeps cat odours at bay.
Very easy to use. Just set ot to auto and it does the rest Super quiet when the fan is at low speed. When the fans it at high speed, you can hear it running, but still realitivily quiet. When on auto mode, it does not stay at high speed very long. Interestingly, it always goes into high mode when I ...
