Thanks ! i never bought any games on my phone at all . <| sep |> The filter cost 38 brand new and can easily be made back if it last long enough . It came with a sleeve cover that will be easy to make if I get the right material . I am hoping the coversleeve will make the filter last longer and i could change this when ever needed . I have a clear space outside where i extract fumes to but sometimes I can smell them when i walk outside my shed , I don ' t like this . Reducing this smell would be less worry . I wish I could add pictures of the filter I made but I am not having any luck . Cheers <| sep |> Blizzard don ' t really do single player games I believe . I wouldn ' t get my expectations too high on this one . <| sep |> Interested in the HBA , PM me .
