Calm-Neighborhood631Multiple Winix from Costco. Significant difference. Hardly any dust in our house. Affordable. Turn off ionizer on them!
Electronic-Owl1429I use a couple of Winix air purifiers from Costco. I have also used a Shark 3 in 1 clean sense. Both have HEPA filters and work well and are also pretty quiet, no problem with running them while I sleep.
LaplacesBox-0096Vouching for Winix. Have several of the $100 models from Costco throughout the house for almost 10yrs and still going strong. Take care of the unit and clean and chg filters regularly. Coway is also great.
QuarrelsomeCreekWinix from costco. I've stress tested it during a wildfire that got within a few miles of my home. I do not recommend Blue Air. Its more expensive and less effective.
rlpfcWe have a couple Winix purifiers from Costco and they're great. High CADR, compact, and they go on sale frequently. The HPA300 from Honeywell is also a great unit.
slickxsparkieThe winix i bought from Costco lasted 2 years. 3/4 of them died last month. Waiting for the last one to join the rest of them. I did buy the newer round one, so maybe we'll try that out for the next couple years
spicandspandWe have the Winix ones from Costco. I’ve bought cheap ones from Amazon before and the hepa filters always look the same every time I checked them so I don’t think they were actually doing anything haha.
staysourYou can turn the plasma wave off and it will be fine. I have it on 3 and its pretty quiet. Also, at my costco that unit was only $100 while on sale.
Winix is pretty solid. You can look up their aham verifications. This one specifically is pretty good. Turns the air in a 300sq ft room 4.8 times on high. For $100, you can put these in every room and call it a day.
For $100 vs $1100 this winix is a solid choice. Especially to put one in every room. The IQ Air has max room coverage of 1000sq ft just like the winix air. So im assuming (since iq air did not specify) the iq air turns the air in a 1000sq ft space once an hour on high. The price difference seems to be coming from the charcoal filter media. You can make a better VOCs filter from AC infinity charcoal filter and inline fan for $300 or so.
Getting the winix from costco means you can return it if you are not satisfied with the product. This is my 3rd unit. The previous 2 lasted 5+ and 2+ years and did not break. All at this similar price point of about $100. Winix is AHAM verified. I do not see the verification for the IQ Air. And both handle the same amount of space except the IQ air is not independently verified. The winix specifies that it can handle rooms of up to 1000sq ft in an hour with 1 air change. The IQ air says it handles rooms up to 1000 sq ft, but does not specify anything else. I am assuming they mean 1 air change an hour.
