Most people buy air purifiers based on brand or looks. That is not how you should choose one.

The only things that actually matter:

• CADR (Clean Air Delivery Rate - how fast it cleans your air)
• Filter replacement cost (your long-term expense)

CADR basically tells you how quickly an air purifier can clean a room's air, meaning higher CADR = faster cleaning.

Filters are the real hidden cost. A typical HEPA filter alone can cost anywhere from ₹2,000 to ₹4,000, and you will need to replace it regularly.

Ignore these two things, and you will either get poor performance or end up spending more on filters than the purifier itself.

I compared both, and here are the best air purifiers under ₹10,000 in India.

How to Choose the Right Air Purifier (Simple Logic)

• Small room (up to 250 sq ft): CADR 200-250 m3/hr
• Medium room (250-400 sq ft): CADR 250-350 m3/hr
• Large room (400+ sq ft): CADR 350+ m3/hr

Always match CADR with your room size. Otherwise, even a good purifier will feel useless.

Biggest Mistakes People Make

• Ignoring filter cost (this is the biggest one)
• Not checking filter availability
• Buying based on brand name only
• Not matching purifier to room size

In many cases, people end up spending more on filters over time than the purifier itself.

Final Buying Advice

If you want a safe choice, go with Honeywell Air Touch V5. If you want cheaper maintenance, Honeywell V2 or Reffair makes sense. If you want reliability, Philips is solid-but confirm filters first.
