5. Which Brand / Model Should You Choose — Based on Your Needs
Here’s what I recommend depending on different priorities:
- If you want a budget purifier with smart features → go for Qubo Q400 or Q500.
- If you need a purifier for a large room and want long-term reliability → pick a Coway AirMega model (or the Mighty for smaller rooms).
- If you want top-tier purification, especially for allergens, VOCs or ultra-fine particles → choose a Philips model like the 3000i or higher.
6. Final Thoughts
- Qubo is the value-for-money, smart, made-for-India option.
