as a result of using this product, I found that my vacuum cleaner was working much better than before. The FILTER is easy to install and has improved the air quality in my home. It catches all the small particles that I used to see flying around after vacuuming .The downside is that the filter needs to be cleaned after each use but it`s a small price to pay for a cleaner home. Overall, i highly recommend this filter to anyone looking to improve their vacuum's performance..
