  • Impressions after 1 year
Size: Medium Rooms
The media could not be loaded. I bought this purifier because it is HSA/FSA eligible and I was intrigued by the NCCO technology which I have not seen offered on more popular purifier brands. I got this because we have cats and dogs, and live in a rural area with lots of pollen producing oak trees that leave a yellow pollen layer on everything in the springtime. I end up getting sinus infections and spend oa week or two terribly sick. The basement in my house has a damp moldy smell because the air is stagnant. I plugged this in my 12’ x 20’ basement bedroom. In an hour or so there was a very noticeable difference. When I wake up in the morning, I am no longer congested. I have used another air purifier and noticed improvement, but not as much as with this one. The air smells clean. I think the ncco and hepa combination is very effective at removing pet and damp odors from the air. I ran into the problem that other reviewers have mentioned when the display malfunctions and the EE notification and NCCO light turns red. I emailed support and they said to do this: Air Purifier Fix unplug the unit for 30 seconds or longer plug it back in 1. Power the machine off. 2. Then hold the power button down until you hear the click. Once you hear the click release the power button and press the fan speed up button. Speed will go up from 3 to 4 and code will appear on the display and unit will shut off. 3. Repeat step 2 but when you hear the click , release the power button and press the fan speed down button. Speed will go down one level and a code will appear and the unit will shut off. 4. Just power the machine on and the light will be blue. 5. If the letters on the display seem off, have the customer unplug the machine and re-plug it. This is to be done after the machine has been reset if necessary. That worked for me and I haven’t had any problems since. I have also tried this upstairs in the living room and it works great. I cranked it up to 10 since there is a lot of open space square footage. After a few hours the air quality is noticeably improved. My nose is less runny and animal odors are gone. This purifier is a bit noisy running on high, but it is a nice white noise so it doesn’t bother me. The video is of the sound running on level 10. ... show more

  • Performance is better than I ever hoped it would be.
Size: Portable
I've been using one since July 14 and am impressed with its performance. I am on the road in a truck camper and , being asthmatic, havebeen concerned aabout air quality. Initially, my concerns were regarding dust and pollen. Recently heavy smoke from wildfires affecting NE Washimgton have resulted in dangerous air quality for me. I am astounded at how good the air is in the camper compared to the smoke, ash, and dust filled air outside. I can occasionally smell a hint of smoke in here after I open the door but the purifier takes it out faster than I could have hoped. I even placed it on the bed, aimed at my face, while I sleep. I no longer wake up in the morning feeling like I've smoked a pack of cigarettes in a smoky bar. Thank you for.this product. You have saved me from the emergency room, and have made my living conditions exponentially better. I just ordered a second unit in case this one fails. ... show more

  • This will remove Voc but needs improvement in other areas
Size: Medium Rooms
I’m an air quality nerd in general and have been learning about air quality and air filtration for couple years. I’m an engineer by trade so I always do an analysis by following the numbers. I Own plenty of high and low end filters ranging from 1000$ to 45$. All varying in quality but you might find the price isn’t always what you get these days. This model isn’t a great one for moving air since it’s so tiny. Particulate matter is sub par compared to others in the price range. You could easily find a true hepa filter with higher CADR. But the uniqueness of this filtration system is the Ncco. Created by an entrepreneurial group in Hong Kong—the idea is based off of catalytic oxidation. I own a pco filter and it emits ozone (I know that smell) and it doesn’t remove voc at a measurable rate. This ncco however has surprised me after I did some controlled test. I initially smelled a bit of ozone ( as it uses activated oxygen) but that soon passed as the directions say it will smell funny but it is expected. If you are looking for something to remove tvoc. This is an option. Better than most activated carbon filters. The technology ncco is robust and removes gases in a reasonable timely manner. Voc gasses are extremely hard to remove as I’ve used multiple systems and even rolled my own carbon filter. This clogs up quick and needs new activated carbon. This unit itself could use improvement for sure. But it’s a viable solution for voc. I wouldn’t buy it for anything else to be honest and I would pair it with a high cadr true hepa filter. Overall I’m pleased as I already have filers to remove PM quickly but I will be looking for better builds later. ncco works for me since I see the numbers get to 0 around there given is no air blowing in stay around there. Amazing if you ask me! Ncco is a promising tech that seems to be under wraps but this could change a lot in today’s age of respiratory diseases. The directions are almost on existent so pay attention to the pictures on the box and read the instructions. You need to remove the bag around the hepa as well as install the ncco chamber. Let it run for a while like an hour and it should work. ... show more

  • Unit does not power on after less than a year
Size: Medium Rooms
Lightly used. Unit suddenly does not power on. Called their support hotline and no one ever answers. Left voicemails and no one calls back. Managed to speak to a "Carla" today after what must be my fiftieth call and she said they have no units to send me a new one nor is she able to offer a refund as she is "waiting on the manufacturer." Avoid this. You have been warned. ... show more

  • Gives the room a nice fresh scent
Size: Large
This is a very well made device. Setup was easy. Internet connectivity was easy. I would argue that is does not really keep up with a 700 Sq/Ft room on it's standard setting. Put it in our 250 square foot bedroom and it does a great job on level 4. We put a bigger unit in the kitchen/living room area. ... show more
