Purchased with extra filters early April 2025 and was not difficult to assemble. Seems well made and relatively quiet on lower speeds. I have been using it on 'auto' for setting so it does move to higher speeds at times and will definitely hear it at higher speeds. 2100 sq ft house in rural area next to farming field (soy beans this year) and placed in rarely used living room. I have noticed a reduction in dust since using. I haven't noticed much of an increase in electricity use (I do track monthly KWH) so it is fairly efficient. Using for 4 months 24/7 with zero problems. I have not received a warning light to clean the filters after 4 months so I am planning on cleaning filters on first of the month so I can't comment on cleaning. Time will tell on longevity. Kind of pricey (at least for me) but I am satisfied with the purchase.

This unit is easy to use and works when you need it.We have it in our restaurant seating area which is about 4800 cu Ft. This unit is supposed to take care of 2500 cu Ft, I believe. However, it works great in our seating area of 20X20X12.I noticed it instantly detects foul orders (dirty mop buckets, garbage cans rolling next to it) and instantly kicks into another gear to clear the air when in auto.The turbo button (not sure it's called "turbo") is a a good way to prep the area if you know you'll be working in the area. We just opened and this came in handy during and after our restoration.It is quiet and looks really nice. It is easy to move and has many control options. We use the auto mode while open and manually turn it off at night. It has a timer and scheduler but we've not used those features yet. There are a lot of filters and many extra filters. That's a nice bonus.A little on the pricey side, but for the volume of air we ask it to clean, and all its features, it's worth the investment.Strange this is, after I've been working all day and stand next to this unit, it kicks into high gear and the indicators show "dirty"... Maybe it's trying to tell me I need a shower? ... I take it that the sensor is tuned to sense humidity and sweat and reacts to conditions in the air.Love this unit, I recommend purchasing.

Works very well. Can be a bit loud when in ultra cleaning mode. Easy to rinse filters. Easy to roll from room to room to spot clean (back room, stuffy rooom/kitchen). Very powerful machine. Able to set up online app to use remotely. Can turn and off and adjust settings remotely. Would buy again.

I bought this for my son who has many animals in his house, and has allergies. It cleans the air amazingly well, removes most odors, and is easy to clean and service. It replaced a HEPA/Bulk charcoal unit that was costing a fortune to keep refilled with filters and charcoal, and is doing every bit as good or better. Being able to wash most elements without generating more trash for the landfill is a great thing.

Definitely a difference in air quality with it running is a bit loud but worth the money

This purifier has literally been a life changer. I originally got it to keep the odor down because entertain and have two cats. Upon cleaning I can't believe the amount of cat hair it picks up. We had it for a full year before a fluke operating error occurred. Customer service was able to replace the purifier within a week once I sent it in for a repair or replacement. I noticed a difference in quality of air when it was gone and when I received it back. It is sleek and blends in with my decor and is quiet, until it picks up an odor that shouldn't be there. If you're on the fence on finding a purifier and spending the money, get this one, it is worth every cent.

Awesome product recommend this to anybody that needs their air clean. My allergies have gotten so much better. I have a dog and cat can cook the smell away quickly definite plus don't have to open the windows in the summer.

For something as expensive as this, it started out AMAZING. It would ramp up I did something like sweep the floor, and if the cat walked in the room, it would ramp itself up just a little bit. No joke, my wife and I could noticeably smell and feel the difference throughout our entire house. However, it shut itself down one day, abruptly, and there was nothing I could do to resolve the issue. I tried all the troubleshooting steps I could get ahold of, but it was dead. Dead as in it was just completely off and wouldn't turn back on. That's the kind of thing that makes me really, really hesitant to get a replacement or purchase another one.I would highly recommend you try something else considering there are tons of other reviews saying basically the same problem: It's going to give out on you, possibly a lot sooner rather than later. You fall outside of the Amazon return window and then you're at the mercy of Nuwave customer support... which wasn't worth the headache to me at all after getting the second set of automated messages. Thankfully I was still in the window to return it to Amazon. You've been warned!
