Review: Quiet and effective. Cuts down house dust. - Purchased 6 months ago to help cut down on house dust and possible cat allergens though mostly because my better half has been wanting one for awhile and I finally broke down. Runs very quiet for the most part except rare occasions when auto fans goes in high mode which is pretty brief. Sensor works well to keep it quiet at night so no problem leaving it in bedroom. I think it is actually doing something because the filters need regular cleaning. It is pretty large but a handle on top makes it easy to lift and move around. The important thing is my wife believes it's helping with the dust. Easy to keep clean and replacement filters are reasonably priced. I plan to purchase another so I can leave one in bedroom and one downstairs.
Review: Passed the Fart-y Dog Test, the Skeptical Husband test, the Musty Crawlspaces Test, & More - First, I selected this based on Consumer Lab's ranking of it as runner-up to its #1 Large Space filter. The #1 selection was a ridiculous $600-$800 while this was nice $230 on sale (vs $399 normal). Heck, make this #1. Key features: (1) It has wifi-enabled companion app - but you can control it entirely from the air purifier itself which is good because frankly being able to avoid potentially cyber insecure IOT app for somethign that's largely unnecessary is great. (2) It automatically turns on plasma ionization when you turn it on, but you press the up & down (fan speed) buttons simultaneously for 3 seconds to turn it off. (3) If you run it on auto, when the lights are off (photo-sensitive not motion detection sensitive), it'll power down into ultra-low speed fan mode. Easy solution, turn off auto and leave it in low fan speed. Our dog farts like she's eaten deer poop. It's either get rid of the deer or the dog (joking), but we love our girl too much. Then there's the crawlspaces that were never encapsulated that give the house a musty smell while we're waiting to get them encapsulated this summer. And the skeptical husband. Enter this air purifier. It has approximately 5 air changes per hour for a 600-something SF space if I remember correctly. Within 30 minutes of turning it on, husbando and I noticeably detected fresher air throughout the house. Low and medium fan speeds aren't overly loud, and actually pleasantly low-key background noise. Even the high-speed is not particularly abrasive or overstimulating for you sensory-sensitive people. Plus it gives you 3 carbon filters from the start, each of which lasts 3 months if I remember correctly. So, all in all, super happy with this. Some reviews mentioned the LED light wasn't reliable - but someone who shall not be named (cough, the dog) audibly farted right in front of the purifier when she was sleeping (comically whoopee-cushion like which, if we couldn't breath immediately at least this time it was not because it was noxious but because we were laughing so hard) and the LED indicator IMMEDIATELY turned red. Ran for 5 minutes then the indicator went back to blue. Super great at dust removal, and our nostrils have been less congested between weekly house deep cleaning too.

### ⭐⭐⭐⭐⭐ Great Air Purifier for the Price... SUPER Quiet...
*by D***D on July 2, 2024*

Much better than a couple smaller, less expensive units i recently bought but, they're good enough to serve their purpous in the other rooms. Much quieter than a larger one i've had for years... this one goes in my bedroom for sure... It's VERY quiet even on fan speed 2 {can fall asleep with it 4 feet from bed} ... On sleep mode, not audible from 4 feet (my ears) at all and can barely hear anything standing right over it. Even at max fan speed the sound is not obnoxious at all while listening to music or TV the "hshshsh" sound fades into the background very quickly. However, setting 1 or 2 moves plenty of air in my room for 24/7 use... well designed. I suspect why it's so quiet is why it's bigger and heavier (as well as whatever airflow engineering from R&D) is reason it is so quiet and yet moves LOTS of air. I suspect more room for sound deadening materials, larger fan motor and fan-wheel plus, large surface area filters makes for higher airflow at lower RPM fan speeds. Comes with One HEPA filter and 4 activated charcoal filter. The HEPA and one of the charcoal filter comes sealed in plastic already installed {don't forget to take the plastic off before use :} the other 3 come in a large resealable plastic bag {nice touch}. My environment is only moderately dusty so i suspect the filter "could" last for longer than recommended but, they are not that expensive so I think I'll replace them as required. As for "Plasmawave" ... there are some reviews that think (among other thing) that it "generates UV radiation" {huh?) or OZONE... Plasmawave was one of the thngs that also attracted me to WINIX. I actually had posted a review for the 9800 a couple days ago , but like a dummy, i posted a link directly to the WINIX website "Plasmawave technology FAQ page" that describes exactly what Plasmawave is and does... I recommend anyone "theorizing" what it is go vist that page... PSA: As for misinformed reviews i've read about Plasmawave... In air-purifiers that have "non-ionising" UV-C lamps, you are not exposed to anything anyway, since the bulbs are inside the unit closed off to direct UV exposure... However, "Plasmawave" has exactly "zero" UV bulbs. And as for those that think they are being exposed to toxic levels of ozone, there are safety regulations and this is NOT an "Ozone Generator" it is a type of "air ionizer" but not a conventional one... to learn more, go to the WINIX website. Great design. Great Technology. Recommended.
