Product review (3 stars): Good item for temp needs with modify
Maybe people should try adapting this to the rear of fan to filter before the air goes threw the blade.... Then use gorila tape tobseao the motor cover area and take
Tie wrapes to secure the filter in four sections tight fit no loose fit....
Of course it won't last long maybe 30 days this is cheap thin filter ...
But to maintain dust and etc on all types fans windows and sliding doors should not be open long otherwise expect your central filter and fan to be dusty ...faster
