    Customers find the air purifier effective and easy to install, with one mentioning it works perfectly with split AC units. The air quality receives mixed feedback - while some say the air feels fresher, others report it doesn't cover the full intake area. Moreover, the filter size is problematic as it's larger than most AC filters, and customers disagree on whether it fits their units properly. Additionally, opinions on value for money are divided between those who find it worth the cost and those who consider it a waste of money.

    Good price as Air purifier is a necessity and not luxury anymore in many regions, I have installed in LG Split AC which is not flat from top so instead I used provided magnets in wall and oneside of machine and it works well as intended. Highly recommended to try.

      Concept is simple: You already have a fan that passes air from an inlet to an outlet. The inlet is a nice plain surface, so all you need is put a filter on top of your AC. I checked using an Mi purifier, and it works. Probably better than the Mi purifier because of the higher range of your AC!

      𝑷𝒓𝒐𝒔:

      - much cheaper than buying a full fledged air purifier

      - the sound is less irritating compared to an air purifier. maybe coz it's far away

      𝑪𝒐𝒏𝒔:

      - it took me 2h to install. The size of filter module was larger than my AC's filter. So there was an open area at one end. I decided to cut a cardboard in the dimensions of the open area and fix it there with tape. Then fill the remaining gaps at the edges with foam, which I didn't have, so I just used newspapers lol.

      - the adhesive at the base of the module, I'm not sure how we're going to reuse that in case the AC"s own filters need to be cleaned and the module needs to be removed in that case

      Filter got choked completely within 12 days, so it's better to buy an air purifier if you are so keen for quality air just spent more money and buy a legit air purifier, it's just a gimmick , as it got choked it's affecting my air conditioner performance, because air won't go through it and my ac stopped cooling efficiently, according to the company if filter get choked you need to replace it , and it ll cost you around 1500rs , if I have to spend 3000rs on filter every month I would prefer to buy an elite air purifier, so in short words it's useless , may be it would be best for those who just use Aircon for 3-4 hours a day ,

      So don't buy it , buy a legit air purifier

      It does bring the pollution levels down. However it isn't a a substitute for a proper air purifier. But when used with a purifier, it does help significantly.

      I will be ordering for our other ac's now that I have tried it for 2 months.

      It is not necessarily a good air purifier. It is best as an attachment for your AC to reduce the cleaning maintenance. It is significantly cheaper than a proper air purifier, but also it is significantly less effective. A proper Air purifier, sits on the ground. Most of the dust is close to the ground. Airth, however, sits on top of the AC, so it's all the way to the top of the room. It will only filter the air which is at a higher level. The circulation will not necessarily push the air at the bottom of the room to the top and filter it. So if you live in a very dust prone area near a road with high traffic, this alone will not be effective. You will have to get a proper dedicated air purifier. However, this can work as a filter for your AC. AC filters are very ineffective and they do the bare minimum. This is a better AC filter, so it will keep the evaporator coils cleaner, hence reducing the cleaning maintenance. But it will increase other maintenances of the AC as you will have to keep the fan always running. The fan motor's lifespan may reduce. It's a waste of money for me as I live in a highly dust prone area and I have both dust allergy and asthma. I need a proper Air Purifier. I can't even return it. So in conclusion, they make a LOT of claims which are not true. But the IIT bombay technology, shark tank marketing convinces you that it'll work for every house. Which is clearly not the case.

      I m surprised that it does not cover the complete AC unit. Half of area from where AC takes air in is left uncovered by this filter the such claims can be made. Half of air passes through filter and what about other Half. And also seeing the quality of device price is too high.
