Review on 2097 Particulate Compatible Retainer Replacement with Enhanced SEO by Moises Dzihic

Although actual filter capacity may meet the filter standard, the filters are very restrictive on airflow. This makes breathing difficult if you are active while using these filters. I chose this brand over the traditional brand I've been using for over 20 years because they were so cheap. After putting these filters on and wearing them for a few minutes, I had to take them off and go back to my regular branded filters so I could move and work without feeling like I was suffering from oxygen starvation. This was disappointing as this non-brand was being offered at such a heavily discounted price.
