Review: Air OK Vistar 550i

The tower-like design is not just good looking but high in ergonomics and functionality. The surface area both for suction as well as the outflow is really good.

As the air purifier market expands its just not the big names but startups too getting into this space. Recently an IIT Madras incubated cleantech start, AirOk Technologies launched Vistar Comfort series.The purifiers are offered with EGAPA Comfort filter that is built with special media to absorb Carbon Dioxide (CO2) and many other acidic gases in the air to make the workplace atmosphere clean and healthier. They recently launched Vistar 550i

Vistar 550i - What's in it?
The air purifier is good looking with smart controls. Vistar 550i comes with sensors that help you monitor your workspace real-time. This IOT integrated device lets you access the purifier from anywhere. Simply download the Air Ok smart mobile app on your mobile device and toggle between modes as it acts like a smart remote.  It works fine for a room size up to 45 square mt and has a CADR of 550 m3/hr. The sound varies from 52 db to 35 db depending on the mode. Pricing is at Rs.30,990

What's Great?

Smart Controls

The app is easy to use and unlike many air purifier brands which talk about IoT and smart controls but even basic connectivity is an issue. Air OK app works seamlessly and smoothly. Connectivity and controls are easy. This definitely deserves a thumbs up.


The tower-like design is not just good looking but high in ergonomics and functionality. The surface area both for suction as well as the outflow is really good.

Room Size

This works well for a room up to 480 sq ft. It's not a bad proposition considering it also comes with an IoT, smart controls.

What's Not Great?


Again it’s the same problem I find with almost every brand. The sound at high mode is too high, even irritating. Even if the air purifier is on night mode at intervals the sound varies. I think as the market matures air purifiers with low noise level low would find a distinct niche.

Worth mentioning is this air purifier does not have the HEPA filter. Instead, it has their own patented technology EGAPA which they claim reduces toxic gases. How well that works is to be seen.

The Last Word
Vistar 500i looks good and is decently functional. Its pricing brings it in direct competition with the big brands like Panasonic, Sharp amongst other big multinational names. What the consumer is getting "more" here are smart controls and room size. What remains to be seen if Air OK will be able to offer decent support and if EGAPA filter will work better than HEPA filter.
