轉載至 中時電子報 洪凱音／台北報導 " 空氣清淨機超夯 居家防疫尖兵"
家中現在只有使用了一台空氣清淨機，看到現在疫情這樣在發展，覺得不太安定，想聽取各位樓主的看法為何，再決定下一步如何進行。(是要再添購，把所有房間都單獨使用，這樣荷包要失血，但是換取健康，避免風險)

大陸那邊清淨機選擇多(恕刪)
醫院的中央空調本來就是hepa的,有做醫院外包就知道,其實遊輪上的中央空調也本來就是hepa啊，所以你會發現醫院牆天花板都還蠻乾淨的，髒是看不到的細菌病毒,但灰塵較少,手術房和加護病房是正壓無塵無菌室，負壓隔離病房是負壓，手術消毒器械的房間上日光燈都是紫外線燈管，一進到這些區域要穿隔離衣，一般病房就不是了,但外氣進來也都過hepa濾網

另外空淨機的濾網真的要固定更換，台灣天氣這麼潮濕上面不知道多少病原體？

我之前也有迷失，其實HEPA...(恕刪)
先提出這觀念不同的看法，
之前有看過其他文章，說事實上HEPA是可以濾掉小於0.3微米的物質的
這篇文章直接提到新型冠狀病毒是否可以透過HEPA過濾
https://smartairfilters.com/en/blog/can-air-purifiers-filter-out-the-coronavirus/
What Does This Mean for The Coronavirus?
If you’re living in a common house, or you’re working in an office or school with a large number of employees, turning on your air purifier can help filter out any virus-sized particles in the air, potentially reducing the chance of transmission.HEPA filters, in one pass, can be expected to filter out over 99% of the coronavirus.
Bottom Line: Can Air Purifiers Capture The Coronavirus?
Air purifiers that contain HEPA filters or even lower grade filters can capture virtually all sizes of solid particles, including particles 0.1 microns in diameter – or the same size as the coronavirus. If you’re living in a shared house, or are working in a closed environment with lots of people, turning on an air purifier could help reduce spread of the coronavirus.
For those in places with central air (HVAC) system, make sure the systems contain filters and are well maintained. If your HVAC contains no filters, installing air purifiers in each room could still help reduce the spread of viruses.
空氣中的新冠病毒可以隔絕。
維基也有提到HEPA是可以過濾比0.3小的物質的
https://en.wikipedia.org/wiki/HEPA
其實，真正的問題是，除非你跟患者的接觸中間隔著空氣清淨機，不然空氣清淨機也只能隔絕空氣中的病毒而已，病毒不會自己走到空氣清淨機被吸。
Joey大有整理中國跟台灣對於空氣清淨機防病毒的看法
http://joeyhc.blogspot.com/2020/02/blog-post_8.html
基本上沒必要專程買空氣清淨機來吸病毒，戴口罩比較實在。
不過最近空氣也沒有很好，空氣清淨機還是可以考慮購買的；甚至新風機也可以考慮。
