@apmalong @flowermusickids @kprather88 Retrofitting with improvised filters is a short term solution. Longer term you definitely want it built in, and filters that can be changed without rebuilding the whole box. UV can play a role too.
@apmalong@flowermusickids@kprather88使用简易过滤器进行改装是一个短期解决方案。从长远来看，你肯定希望它内置，并且过滤器可以在不重建整个盒子的情况下进行更改。紫外线也可以发挥作用。
