This HEPA filter is a great addition to my home and kitchen! After I put it to the test, I saw a major difference in the air quality in my home.All of the dust and allergens were trapped and it made a noticeable difference for my family. The filter is easy to INSTALL and fits perfectly in my vacuum. The only downside is that it needs to be replaced every few months. Overall, a great investment for anyone looking to improve their indoor air quality..
