Ilife makes it myself, cheaper actually: https://www.amazon.com/PX-F010-ILIFE-Performance-Filter-V3spro/dp/B07ZKB9WXV?ref_= ast_sto_dp However, they are not easy to find. I've just sent back the tested filters I ordered and am replacing them with ilife filters, don't know yet but hope they work better. The filters in question showed up in the "commonly bought together" section and had mostly good reviews, so I bought them. I checked the size and got the following result: Fits your: ILIFE V3SPRO. After realizing that it didn't really fit my ilife v3s pro, I checked other 1 star reviews and found that others had the same issue. Sometimes I wish Revane hadn't done that "frequently bought together" thing. :-( Assuming they work, people are better off buying real life.
