不同的空氣淨化技術方法：從活性炭到低溫等離子

活性炭吸附

利用活性炭或碳纖維的高比表面積，對空氣中的有害化學氣體進行化學吸附，從而達到淨化化學汙染物的目的，迷你空氣淨化機對淨化室內揮發性有機物和異味有一定效果。

優點：使用一個簡單，在短時間能吸附具有一定的汙染物，主要是通過針對不同揮發性有機物和異味。

缺點: 隨著溫度、風速上升到一定程度，汙染物的吸附可能會自由，再次進入呼吸空間，活性炭很容易達到吸附飽和，去甲醛空氣清新機必須更換過濾材料，否則會造成二次汙染，累積成本高。

光觸媒

在光的照射下，會產生類似光合作用的光催化反應，產生氧化能力很強的遊離羥基和活性氧，分解甲醛具有很強的光氧化還原作用，直接分解空氣中的汙染物，從而達到消除空氣的目的。

優點：光觸媒技術可以進行有效工作分解甲醛、苯、TVOC、氨、乙醛等。

缺點: 有效效果只能維持3個月左右，需要連續施工，無法在無光環境下工作; 對細菌和病毒無效; 價格昂貴。

普通氣態臭氧發生器

傳統電路板中，電子的正負極電離產生氣態臭氧，臭氧與空氣中的化學汙染物發生反應，改善和調節空氣。

優點: 可去除甲醛、苯、 TVOC、乙醛、氨和細菌。

缺點:無法在高溫高濕環境下工作;紫外線照射針對的是甲醛;由於釋放濃度高，純度低(小於70%)，釋放時伴隨氮、氫化合物，對人體有害;人機共存無法實現;有效使用壽命短，有效作用只能維持3個月左右。

紫外線臭氧發生器

這種臭氧發生器是利用特定波長(185毫米)的紫外線照射氧分子，使氧分子分解產生臭氧。由於紫外線燈體積大、臭氧產生量低、使用壽命短，所以這種發生器的使用范圍較窄，一般用於消毒櫃中。

負離子淨化

當負離子與空氣中的生殖細胞結合後，細胞內部的能量被轉移，結構發生變化，導致其死亡，使空氣中漂浮的煙塵、花粉等吸入顆粒物聚集並自然沉降，從而達到淨化空氣的目的。

優點：高壓放電等技術使空氣質量產生負離子，負離子與空氣中的顆粒主要汙染物可以結合，使微小的顆粒聚集、沉降，對淨化環境空氣有一定影響作用。使用一個比較分析簡單。

缺點: 不能分解氣味、有毒的甲醛、苯、 TVOC 等有毒化學物質; 高溫高濕環境無法工作，必須依靠空調的內循環系統才能工作，否則無效; 一旦技術故障，放電電極很容易產生氮化物或光化學物質，從而對人體造成傷害。

低溫等離子技術

高壓高頻脈沖放電形成不對稱的等離子體電場，使空氣中的大量等離子體逐級碰撞。產生電化學反應降解有毒有害氣體、活病毒、細菌等。

優點：

連續消毒、殺菌、除臭、除煙、除塵，無有毒物質產生

可人機共存

節能降耗，比去年同期節電60%。

具有經濟持續消殺病毒、超強淨化技術能力、祛除異味、消除靜電進行功能、增加一個氧氣含量等

使用時間長，免維護，無需更換任何配件
