Winix HR900, Ultimate Pet 5 Stage True HEPA Filtration Air Purifier, 300 Sq. Ft, White

It's large so effective in big rooms. It's sensitive and uses a large but discrete light to show when air is less than optimal. Ours goes from blue (good aq) to yellow when the cat walks by it or uses the litter box. We have found that ours doubles as a pleasant nightlight. I find it amazing and I've had no sore throat since we set it up 5 days ago. I can't believe the difference already. I purchased two as I live in a two-story farm home. I have foster critters galore. It is amazingly quiet!! I do not use the sleep mode as I prefer a little soft brown noise at night. It's just...so quiet!! I'm as surprised at that as I am how effective it is.Most importantly, we experienced the horrid wildfires in Oregon this September and I was using the homemade box fan filtering set up at first in a pinch. Air quality was off the chart as you would expect. It's been 7 weeks since the fire hit. We've struggled with odd respiratory/throat and a random sharp dry cough since. These symptoms no longer exist when I'm at home. But do at work which tells me these machines are doing something remarkable. I would highly recommend spending the $$ on these. It's well worth it to us so far. Amazing really. I do use the first thin pet filter *which they include 12 of these inside the box when shipped*. There are a total of 4 different types of filters in the machine once you set it up, which is EASY. All included to get you through the first two or three months at least. Two are washable (1-semi think carbon, 1-thin nylon{?} mesh), the paper filter is thick and very effective and will need to be replaced but it says they can last up to 12 months which mine will obviously not do. I'll update the post when it. needs changed. Finally, The paper thin fibrous filter for pet hair/dander filter which as stated above, comes with 12 of these and I'm sure I will go through these fast. No matter. It's totally worth it so far! Just checked filter two that is in the busiest part of the house. ALL filters still look like new almost a week later. YaY! These also have a 'dust' sensor which is nice.

We live with two dogs. Both shed a LOT! One is part hound with a strong odor. Our vet uses this brand in his exam rooms, but we chose this model for the added pet dander filter (it comes with a dozen). The extra filter takes a few minutes to install, but it works!We use this in our +/- 280 sq ft family & TV room. The noise level is unobtrusive and the unit has made a big difference in reducing the odors and allergens. RecommendedUPDATE:We purchased this unit in April 2023 and were very pleased with its performance until December 22, at which point it stopped working.It displayed two blinking fan speed lights and could not be restarted. We reported the problem to Winix and were notified by tech support that it must be returned for repair.Several hours later I received the following notice from Winix:"Thank you for reaching out to Winix America.We do apologize the Winix Limited Manufacturer warranty does not apply to units purchased by third party sellers. The proof of purchase provided notate that this item was sold by S&E Mart through Amazon. We recommend reaching out to the seller for further assistance.Best Regards,Winix Customer Service"The Amazon ad did NOT indicate that the item offered was not eligible for the manufacturer's warranty!

I had my eye on this for a while and was debating between this and a cheaper option. I decided to go with this because my massage therapist has a different model Winix in her office and it's always so fresh and clean in her office. I have been using it for about two weeks.I regret to say unlike some users the filter has not yet grown a second dogs worth of hair, but it works well. It can't be expected to pull dog hair from the carpet 6 feet away but I have noticed cleaner air and less dust buildup. Everything feels a little bit fresher and brighter in my apartment.It's nice and quiet. Barely noticeable on any setting other than turbo, and even then it's a light white noise and not distracting. I typically keep it on medium. All in all I am very impressed with the product and feel that I made the right choice in purifier.On a side note, I noticed in most of the negative reviews with pictures that the machine is pushed into a corner or right up against a wall. A purifier must circulate the air just as much as it must clean it. So the purifier needs a certain amount of open air around it to properly circulate the air. If you don't notice an improvement read the manual to make sure it has enough space!

I have terrible year-round allergies. I keep this running 24/7 in my bedroom. Keeps dust to a point where I don’t even dust my room. It automatically quiets at night. The plasma wave indicator is very sensitive, so I know it’s working. Definitely helps keep allergens away and I rarely have sleeping issues anymore. I can even keep my window open at cooler times of the year. That’s something I was never able to do before. The filter lasted over a year with changing out the pre-filter. Makes the annual filter replacement cost worthwhile.
