消委會d 比較好撚片面
乜產品都係吹奏平野
同埋剩係比較某d 方面
例如大西北呎價平過港島呎價
就話大西北好撚抵
但其他範疇完全唔提

消委會都信 信果個應該弱智
屌米依d 大陸牌子都要討論
自己research, 係咪要人教埋你抄作業咁羞恥啊
睇緊部 BM100 醫療級都係 $5000 
DYSON 果D 都係9 估, 而家新款唔知有無
How an Air Purifier Can Help Reduce Dust
All of these tiny particles move around indoors by floating through the air until they finally settle on a convenient surface in our home. By adding an air purifier to a room, many of these particles will be trapped before they have time to settle, not only making the air more pleasant to breathe but reducing the accumulation of dust on our tabletops, books, and shelves.
The most important tool for filtering out dust is a true HEPA filter. HEPA filters were designed in the 1940s to protect scientists working on the Manhattan Project from tiny radioactive particles, and due to their efficiency at removing particles from the air they gradually became used commercially in filters and vacuums. A true HEPA filter is rated to capture particles at 0.3 microns in size with 99.97% efficiency, although it can capture both much larger and smaller particles as well. The 0.3 micron size was chosen because it is both the hardest size to trap and the size most easily drawn into lungs.

睇你要空氣清新機黎做咩
活性炭係用黎除臭果類
Hepa係除微粒，鼻敏感岩用
大多數空氣清新機都係風扇+上面2種濾網
睇下佢hepa網係級數就知好唔好
不過機身設計有缺陷漏風都會有影響，但正常人好難測

hepa is key , xiaomi 無hepa即係唔使要
連燈問支那野喎 得一個答案：會爆炸
我都係

買咩都好總之就唔好買 dyson
dyson 9成錢都買左佢個 design
用同一個價錢買其他brand
功能上有更好選擇

但係問dyson都係9成話貴無用
咪係，大都係計開機時間來估
為左filter 錢換既, 你最好查清楚
pana 好似玩到1-2年?
小米大個隻唔知玩到幾耐, 但2s 自己話濾芯得4-6 個月, 3都好似係咁上下

冇hepa我就唔會買
如果你話你目的係想活性炭除臭果類目的都仲可以接受
但買得空氣清新機一定係全都要

我主要都係訓覺閂埋房門先用
平時都係睇個讀數，如果太高就閂窗玩循環空氣

唔係叫你買小米, 但小米都有hepa filter
唔關事,問過CS佢話純粹係計算開機時數去判斷洗唔洗換
