"Winix is great in my experience. Grt the correct size for your room, run it on a higher speed. You want lots of air changes"

"The Winix has a light sensor that doesn't allow it to work in auto mode in a dark room. ... If I put mine in auto mode and turn the room lights off it goes into sleep mode which is basically turning it off."
"A window can be open across the house and my Ninja will notice a drop in AQI and speed up the fan while the winix just continues to blow slow. ... I have noticed if I turn the fan speed up on the winix it will notice the AQI change, but that makes the auto mode useless."

TopSherbert6054 0.0Just throwing this out there to help with allergies. As you said you have lost your elder dog (rip buddy). Is this new pup the same breed? Just because he was immune to the other dog don’t mean that this one brings new allergies. But it can signify that it’s a different breed that kid can not tolerate. Each breed sheds differently from the other. Some more then the rest. Just a thought. I’m allergic to cats and dogs. But more so cats. We have the homedics 5-1 that really helps. But it’s recently gotten so loud that we are making the switch to the Winix brand. I would recommend staying away from the Lrg round units. Go with a rectangular one.
2plus2equalscats 0.0I got annoyed when my winnnix developed a noise, but then I realized it was the unit I’ve been running almost 24/7 for ten years. Bought another refurb and I’m going to attempt to take the ten year old one apart and see if it can be fixed. I imagine there’s buildup at the parts you can’t regularly clean.
I double checked and it’s my 2019 era one that has the noise! The 2015-ish one is still fine.
1-800-get-lost 0.0Both of my Winix air purifiers started smelling like smoke, they are different models, cleaned weekly and filters changed regularly, I don’t recommend them.
7Sans 0.0you can't beat the physics. what you want is the big size as prioirty thing to look for first. then you can look into other things but the size of purifier(filter) has biggest impact. winix is solid imo for basiaclly 99% of the use case.
Additional-Regret-17 0.0I have the Winix. No issues to date. I don’t use the plasma wave feature.
Aggravating-Tune6460 0.0Definitely recommend Winix. Australian and comes out top of various tests. (If you haven’t been warned- don’t buy Dyson) Super sensitive to more than just particulates and has a ‘pet filter’ that is changed monthly that goes around the main filter and prevents it getting clogged with dust. Helps to prolong its life if you have pets
alpina07 0.0Winix works great ! I have 2. Zero complaints.
Alternative-Pair-812 0.0AVOID DYSON AT ALL COSTS!!! They look cool but are RIDICULOUSLY overpriced for what you get. Spent $500+ on one and my cheaper Winix outperforms it by a mile. Total marketing scam.
Arkmodan 0.0I would buy whatever Winix fits your budget and space. My two Winix units are 11 years old with 24/7 use and still going strong!
ArthurDent4200 0.0I like the Winix. Bought three. One became noisy after 3 months. Returned and bought a new one to replace. Thank you Costco - this is why I spend thousands in your stores!
