I have an Oransi air filter, they are extremely well made and are priced accordingly. I have two so during work(wfh) both me and my Wife can be working in clean air envs(in our offices) and at night we put them into our bedrooms so we are breathing clean air overnight. Fun fact they also work well to get strong cooking smells out of the house/kitchen. Cannot recommend them enough.
