Get a true HEPA unit sized for each room. Xiaomi 4 Compact works great for bedrooms, Dyson or Thorair if you want bigger living-room coverage. Run them 24/7 on low and swap filters regularly.

I have this, works pretty well and some good online reviews for it. It's for smaller rooms though. Got mine on Lazada on sale for 1.8k baht (was lucky I guess).

I also have the very old 2S and 4 compact and I can still buying the filter. You can find filters aplenty in Shopee or Lazada. Even off brand ones that are compatible. The Xiaomi Air Purifier 2S is from 2017 so it’s nearly 10 years. Whoever said Xiaomi stopped making filter is just BS.

I have had the Xiaomi Smart Air Purifier 4 Compact since 8/2023. It's great and is still working, though na used up yung filter 2 weeks ago.

Yeah, actually di pa ko nakakapalit since nagaantay ng sale (this 8.8). But yes, nag 2 years siya before nag 100%. It's more or less 24/7 since WFM. Mahal yung filter mismo (800 php pre-voucher), so take that into consideration po

Xiaomi, dari yang 4 compact sampai 4 elite aku ada semua. Cukup ngurangin bulu yang beterbangan sama alergiku. Kalo menurutku ga perlu beli yang mahal, 4 compact atau 4 lite udah bagus, kalo nanti ada duit lagi, beli lagi yang murah. Lebih baik punya 2 yang murah daripada 1 yang mahal. Tapi ga mungkin sampai gaada bulu yang terbang sama sekali, mustahil sih. Combo yang paling top tambahin lagi robot vacuum, jalanin 3x sehari.

Air purifier nyala 24 jam, cuma mati kalo mati listrik. Yang 3x sehari robot vacuum. 4 lite 1.2jt di Xiaomi official store, kalo 4 compact terakhir 800an aku liat
