This video is very informative. I had watched other KZbin videos.on the topic "remove change Alto 800 cabin filter". They showed how easy it is to remove the filter. I kept struggling, trying in vain to pull the lid off. Example video here kzbin.info/www/bejne/qWnckomOh7-XbZI It was after watching your video that I realised that my Alto 800 has no filter and no lid. Thanks😀
