Review on Eco 420 Personal Air Filter: Aluminum Air Purifier with HEPA and Carbon Filters for Superior Air Filtration. Eco-friendly Solution to Save Money and Reduce Plastic Waste. by Christine Dhillon

This is an addendum to my last review, it was just a bad filter, I bought additional filters and now it works fine, I would definitely recommend it over Smoke Buddy which I also use have. 1.) Customer Service Although I bought 2 additional filters to replace my original clogged one, the owner of the company sent me 4 additional filters as a goodwill gesture and a personal handwritten letter. 2.) The Smoke Buddy is bulky and hard plastic which makes my face hurt when I have to push hard to get a good seal even though it has great airflow. 3.) The ECO420 is slim and has a soft rubber mouthpiece and base. 4.) ECO420 has replaceable filters.
