Air Purfier - Simple

This is a simple small functional air purifier. I made it for my son's school experiment and want to share here if anyone is interested. This uses a 120mm standard PC fan, carbon filter (cut to size), HEPA filter (cut to size) and MESH filter at the front to stop any dust, hair etc. I used these below filters and fans for the model, so something similar in the thickness and size will work too. https://www.amazon.co.uk/dp/B09DS63YQF?ref=ppx_yo2ov_dt_b_fed_asin_titlehttps://www.amazon.co.uk/dp/B097B4SH55?ref=ppx_yo2ov_dt_b_fed_asin_titlehttps://www.amazon.co.uk/dp/B094R6ZGFP?ref=ppx_yo2ov_dt_b_fed_asin_titlehttps://www.amazon.co.uk/dp/B0CBBK1D1R?ref=ppx_yo2ov_dt_b_fed_asin_title MESH will go in the front and front cover on top of it. HEPA go in next and then thin slot for Carbon filter then FAN (make sure FAN direction is pulling air in through the filters). I tested it with a air quality monitor in a box and used smoke, power and perfume to verify its working as expected.Boost MeIf
