Hi. I have a Hoover vacuum cleaner that I have been using for several years. Even after so many years, their device works great, and I know for sure that I can count on this company when it comes to durability. But since I often use a vacuum cleaner, I needed to replace the old filter with a new one. I found a lot of options on their website, but I still didn’t understand which one I needed, so I turned to hoover customer service after which an employee of their company helped me with the choice.
