We ran tests using our Original DIY purifier, and found that you should change your filters after around 140 days (in Beijing air). This means a pack of 4 HEPAs should last you a year.
For Original DIY:
4 filters (to last you a year)
For Cannon：
4 filters & pre-filters (to last you a year)

I had the cannon fan & HEPA filters shipped to ireland to treat my sensitivity to fibreglass insulation dust in a 25m sq basement (no windows). I had tried to clean the air with expensive vax & blue air systems but neither performed well. The smart air cannon system is WAY better at this particular job – and I’m not quite sure why!! Shipping to Europe is expensive but well worth it. I totally recommend this system & am ordering more filters now.
