Q1000

lemme share some of the research I did while choosing mine 3ish weeks ago. What you want to look at is CADR. This is measured in m3/hr so ideally you could simplify your search and choose the highest number you find in your range. The Sq ft number is not reliable in Delhi in my opinion. As my budget was also 20K i short listed the following based on what was available at local retailers nearby: 1. Honeywell P2 - 550 CADR 2. Phillips 4221/61 - 600CADR (I bought this) 3. Qubo 1000 - 600 CADR 4. Honeywell U1 - 700 CADR. (most expensive) Most people would be okay with a 550 CADR but my room is tall so i still see the AQI go to 200 at full.

I have Phillips, Mi, Qubo and Coway. For your use, I'd recommend Qubo Q1000. Second choice will be Mi. Phillips is expensive for their CADR. And maybe later a smaller Coway 150 to complement it.

I'm have the following purifiers for my family of 5. Phillips 2887 and 1215. Mi Purifiers 2, 3 and 4. Coway Airmega 150 and Qubo 1000C. Not sure about replacing filters every 3 months. We clean it once a fortnight or month depending on the pollution. Mi and Qubo give filter replacement alarms. They say 9000 hours to 15000 hours. So not sure how you came up with 3 months. 90 days x 24 hours is about 2k hours of filter use only. I've placed the Phillips 1215 in the kitchen to reduce pollution in the rest of the house. I didn't think much about Co2 but will see if I can monitor. I counter room cooling with a oil based heater since it doesn't alter the room humidity unlike convection based heaters.

Qubo Q1000 has an unmatched CADR for the price. It can cover a greater area. Mi app is better than Qubo.

Yes. Discontinued but filters available easily. Phillips doesn't remind me to replace filters. It just goes F0 and you clean filters and put them back. Which is a boon and bane. I would still recommend Qubo cause of its CADR and coverage..that's the main thing afterall.

I recommend Qubo Q1000 because of its coverage.

I have been using the Qubo Q1000 since one year. Not had any major issues.

They claim 10000 hours or something but I changed it after an year. It was 4.5k

Living Room - Qubo Q1000. I am using it since Oct24 when it was launched. Not had any issues. Changed filter in Oct25. Bedroom - I use Xiaomi 4, similar decent experience. Ordered a Dyson Hushjet recently, will get today. Will update on how it is

More than an air purifier, I think you need proper over-stove exhaust ventilation. Also, what type of cooking do you do? Indian cooking, for example, involves a lot of smoke and strong aromas, so proper ventilation becomes even more important. Here are a few tips that help: \- Make sure your exhaust fan is running while cooking \- Open a window near the stove to allow proper airflow (inflow and outflow) \- Keep the exhaust running for a few minutes even after you finish cooking, as smoke and smells can linger As for air purifiers, it's better to place them away from the kitchen stove, ideally in the living room or an adjacent space. I use the Qubo Q1000 in my living room (I have an open kitchen layout). I can't say it's a miracle solution, but it does help noticeably, as long as I also ventilate the kitchen and run the exhaust fan. You might need a more powerful one than Q1000 or multiple of them, depending on how big your space is.
