Customers generally like the cleanliness of the air purifier. They say it cleans the air well, and the filters are expensive and don't last nearly as long. They also appreciate the percentage of air cleanliness display on the front and top, and say the HEPA filtration is terrific.

Customers like the auto feature of the air purifier.

Customers are mixed about the air quality indicator of the air purifier. Some mention that it picks up the slightest change in air quality and corrects immediately. They also like the auto feature and say it clears up air to breathe clean air. However, others say that the air sensor is a joke and it shows a corresponding drop in airquality.

"...3 - The air purity sensor seems to be very accurate...." Read more

Customers are mixed about the value of the air purifier. Some mention it's well worth the price, while others say that the filter is very expensive and 30% of the device price. Some say that it works but is not worth the cost or the cost of the replacement filters. Some customers also mention that the purifier sucks up their electric bill and blew air around the room like a fan.

There are some things you need to know
I am hoping this review is helpful to anyone who is thinking of buying this or has already bought it. This air filter does function well but there are some things you should know. To paint the picture, i live in a studio/1br apartment. The only door is to the bathroom, so everything is for the most part open flowing air. Our neighborhood is on a cliff facing NYC and there is a lot of construction in our area. We also only have 2 windows at the front of the apt and 1 at the back. Lastly we are 2 adults with 2 cats. This apartment generates a lot of dust and hair. I bought this air filter with the 6 fans to help clear the air in this large open space. After using it for more than a month... i have learned quite a bit. First, the sensor is pointless. It will mostly say 100% air quality. The actual sensor is not where the air passes through, so in my opinion this will never be accurate. 2nd, i dont think the filter that comes with the system is effective. After using it for a month with the original filter, it barely collected any dust. I dropped a few clumps of dust by the vents and could confirm it was not sucking in the air even at the highest setting. Out of frustration, i took out the filter and decided to cut out the top layer of it which seemed to have too much of a smooth quality for a filter. Afterwards, the air sucking quality dramatically changed. I have been using it without the top layer for a week and as you can see in the picture, this has gathered A LOT of dust in just a week. The black circles are just some filters i had on hand for a project. Some tips: 1- if there is a thin layer on your filter, consider cutting it out and using it without this quastionable sheet. 2-Move the filter to different rooms based on the amount of activity in that room. I mainly hang out in my bedroom, but will move it when i am cleaning a specific area of the home. 3- you may want to add wheels to make this easier. 4- have the back vents facing the room. Who cares about the screen when the number always says 100. I care more about having clean air and maybe you do too. 5- I also found that home depot sells air filter replacements in different dimensions. Dont worry about buying these expensive ones and use those for the replacement. You can also find the charcoal filters in different sizes on amazon.I was unsure at first but i like the system now. The sound on the highest setting is a bit loud. I only have it on the highest setting when im cleaning or overnight for white noise and i keep it on the lowest during the day. The remote is pretty convenient for these adjustments from bed.

5.0 out of 5 stars Quiet and Automatic. Stylish Look. House Feels Cleaner and Allergies Seem Better
Reviewed in the United States on October 31, 2022
The whole family loves the stylish display. It gives the percentage of the health of the air. It is placed near the kitchen. When running normally, it is silent and hovers around 96% to 100%. When you start cooking in the house, especially something with high orders, the percentage immediately drops to 60% or lower and the fans kick on to start filtering the air. You can scroll through the display to see what size of particles is it monitoring. The air quickly is cleaned and you will notice no lingering odors in the house hours later with specific meals. Once the percentage drops after a few minutes, the fan noise goes back to silent. It's nice to see it actually noticed, so you know it is working.

If you plan to put this in a room, all the lights can be blacked out, so it will not be glowing in your room. It comes with a remote, but I leave it on auto, so I have not had any real need to use it.

If you want to improve your house, this is a good thing to start with. I consider this a luxury, but all my kids' allergies were getting bad, so I need to try something new in the house. It is worth it only if you know you are trying to fix a problem.
