Direct selling air purifier are just overpriced good product. Atmosphere claims their HEPA filter is that loooong. When I pull out my Sharp's I laughed. And their ad in youtube is comparing their huge filter with small competitor model.

Choose wisely. Don't let ads or other gimmick get you to pay through your nose. What u actually need. How big is your room? What do u want to achieve?

What I need is only a certified HEPA and Charcoal filter, to filter out most dust/mites and odour. I don't need 100% clean air or all other gimmick (and pay thousands more). Humidifier is never need in my house as even with a/c running my room humidity is only 45-50% which is around the ideal humidity.

So I got myself 2 Sharps. But Sharps replacement and after sales service sucks! Anyway, the newer model's filter can last 10 years. Happy with them

Frankly. Not much choice in Malaysia.
