r/AirQualityBEST AIR PURIFIER FOR THOSE STRUGGLING WITH ALLERGIES

Air purifiers can definitely help with allergies by filtering out dust, pollen, and other irritants from the air. The key is to get one with a True HEPA filter though. I have t[his one from Xiaomi](https://amzn.to/43IEKFX) and am very happy with it. If money isn't a problem you could go with the Dyson ones

r/smarthomeWhat's your best pick of home air purifier that actually improves indoor air quality?

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.

agree sa comment above, depends sa room size. i have small room (but not so small…) and i use xiaomi air purifier compact 4. i did a [review](https://www.reddit.com/r/ShopeePH/s/9jtjY36Tdz) in this sub a year ago. so far so good naman yung two units, wala pa akong naeencounter na error. due na rin for filter change yung nasa room ko but yung isa around 50% pa. na vacuum ko na once ung filter kasi ang daming nakuhang dust, hair, onting fur.. yung dog ko naman ang may allergy so sya ang may gamit talaga 😅

r/RentPHHighly recommend this for pet owners

I got Xiaomi Smart Air Purifier 4 for 4000 THB from Lazada which has a display. And according to that PM2.5 dropped by 90+% from roughly 030 to 003. The 4 Compact is cheaper and still huge, but lacks the display for filter status in percent and PM2.5 which provides peace of mind.
