I use this purifier for my living room which basically includes my shoes and where my cats litter box is, the kitchen and my TV and computer setup wheee I have a desk for plants, for my gaming, and for my work, so three areas. I also have a TV my cat sleeps on. I’m not an expert in purifiers but I know that this product does a good job at least in purifying the side which my shoes and litter are not on, leaving me free to feel good about being there and not spending too much time in my room now. It’s been such a huge benefit. Now, as the shoes and cat litter are on the side on the kitchen, I actually place on of the purifiers side facing the litter and shoes and feel more comfortable doing more cooking in the kitchen. I notice less smell after cooking, basically pure air the next day. Disclaimer, I do use an air fryer so it greatly limits smell. I bought a Honeywell purifier for my room which is about 100 to 130 SF. The living space is probably a total of 400 SF and I estimate this actually purifies 75-100% of the space. Therefore I must say there is a chance that you get what you pay for in this product, in terms of circulated purified air flow. The quality based on filters is indeed top tier. This purifies more air than a Dyson which hardly has any air it actually takes in and purifies. This is because this purifier in particular has two sides of filters that are bringing in more air than the purifier above which is pushing clean air out. Unfortunately there isn’t necessarily circulation but I assume the upward flow naturally makes its way around the living room. However, it’s quite obvious with the design there is a lot of nice clean air circulating. I feel much more comfortable in my living room and really look forward to blasting this baby to do my gaming in the other corner, and I am looking forward to working at my standing desk every morning as well. I can say that I don’t need to open the door to let clean air at all. I think it’s a great investment at least in terms of design, clean air flow and power, but I am not sure about how much square footage it covers. I would imagine there has to be a premium for the design and higher quality filters, and 4 different levels of power. There is also a very pleasant sound when turning it on and off, and it looks quite modern as well, complementing the space right at the front door, so it cleans the air of the litter, shoes and kitchen.

We are very happy with this machine. It seems well-built, and is somewhat large and heavy, but not unmanageable, having wheels on the bottom. This can be handy, as the noise level on level 4 might make you want to move it around some to find the best balance between air circulation and noise. It is quiet at levels 1 and 2 (at level 1, I measured 24 dBA at 5 feet and 22 dBA at 10 feet) , reasonable at level 3, but somewhat loud at level 4 (54 dBA at 5 feet and 43 dBA at 10 feet. Our refrigerator is about 34 at 5 feet)We have had a large amount of smoke in central Texas for a couple of months, due to both agricultural burning and wildfires in southern Mexico and Central America. The outside PM 2.5 has been hovering around 100, but occasionally spiking to over 150. Due to having a person with impaired pulmonary function in the house, we monitor both outside and inside air quality. We have had a much smaller air purifier in our bedroom, and we have verified that it works in that room, but it does nothing for the rest of the house, which is over 3,400 square feet with high ceilings in every room. Our inside monitor has generally been about 70% to 90% of the outside reading, with the ratio being higher when the wind is blowing hard and forcing smoky air through the house. When I first turned this on, the inside level dropped within minutes from 80% to 40% of the outside AQI. If we run this new unit on high, we can generally keep the inside AQI to a range of 20% to 40% of outside AQI.The machine is loud on level 4, so it cannot be used at that level in the bedroom, and even level 3 would probably be wearing after an hour or so. So, we use the device in the great room, which is quite large, with ridiculously high ceilings. This substantially improves the air quality in the bedroom as well, but this is definitely dependent on wind velocity. When the outside AQI is high and the wind is blowing hard outside, and we are not in the great room, we run the machine on level 4.This afternoon, with moderately high wind and outside AQI at 120, we were at 54 inside, while running the new machine at level 1. We increased it to level 4 about 20 minutes ago, and the inside reading is now 36 and heading downward.
