Air quality is great. Noise level nothing. Value for money. Works amazing because new construction going lots of dust is coming. It’s very easy to handle. Its portable not heavy to move in house

Good air purifier with all the required features. It turns red if the AQI in the room is high, and orange if it is moderate. Blue means the air quality in the room is good. It has an auto night mode, which switches it to silent operation when the room lights are turned off at night.

This device definitely helped improve the air quality. I wish they had given the washable AOC carbon filter with this device since the next model has it. The device is silent at fan speeds up to 3 and audible beyond that. Some might think the sound is too high in fastest mode, but if you usually keep the device away from you, you will not hear it. The device has auto function which senses air quality and adjust the air flow. It also has a time that you can use to turn it off automatically at a set number of hours. The night mode turns off all the lights, so its useful when you are using this device while sleeping. The build quality of the device is pretty good. Overall, I am happy with this purchase.

A very good air purifier with a washable pre filter and carbon filter.Design is okay. Easy to install .Noise level is surprisingly low and in night it automatically reduces fan speed if auto mode is selected. As for allergens I think it’s doing a decent job.Its a good value product overall. Plasmawave feature actually works and odour is drastically reduced.

5500-2: Cons: 1. They don’t have remote in Indian version and they don’t mention it 2. The sensor are not PM sensors. So auto mode won’t work as expected in Indian scenarios Pros: 1. Beast in the segment minus the tech, if you get this around 13-14k 2. Battle tested for 9-10 years in market 3. Has many third party replacements T810: I complained about fake t810 filter around 6 days ago. The filter didn’t have carbon inner layer and I have been calling them since then and they only said that the would call me back, but now they stopped picking my call and replying to my texts. Big red flag: The service is handled by one guy and one girl and they use a personal phone number. I’m not sure if this is a scam or something else :( My return window is still open if I don’t get the help I would return this product.

The packaging that this air purifier arrived in raised serious concerns (see the image attached). The air quality indicator is a gimmick, at least on my unit i could say that it was acting crazy, on auto mode, it would just turn red/amber on it's own even in a empty-closed room of 130sqft and the surrounding AQI is 130-140. Given not so harsh pollution and this air purifier (based on specs mentioned) being more than enough for the room size, this thing should've just stabilized after a while but it didn't. On top of this, it is a bit noisy, it almost sounds like a cheap exhaust fan on top speed. Lastly, I'd say don't fall for the plasmawave technology, it generates small amount of ozone which yes is a pollutant, the company might say it's negligible, the tradeoff is nice and works wonders to clean air but for me it's a clear no-no. At the end, I had to return this.

Machine works good, it filters air good. If it could have digital screen to show cureent AQI then it would be great machine.

It's so quite and works faster. auto mode is too good. In addition we can off and on plasma mode
