Review on 🌬️ InvisiClean Aura IC-5018 and Sensa IC-5120 Air Purifier Filter: True HEPA and Activated Carbon Replacement Filter for Effective Air Filtration by Julio Solano

I am satisfied with the exchangeable filter. The price seems insanely high considering what it is and there is no alternative to it. I bought the filter a year after purchase and have run it in my room every day. I had a yellow ring burn for about 5 months but I didn't care. Then last week it suddenly turned red, so I figured it was time to change it. After installing the filter change button and holding it for 5 seconds, the yellow light will still be on instead of turning blue. I wish I knew what to do to fix this.
