I have a Dyson V11 cordless vacuum that I really like. I use it every day, so of course I have to change the filter from time to time. Branded filters are slightly more expensive, so it will be a pleasant surprise to find another branded filter that is quite affordable and works quite well. They are very easy to install. You simply pull out the old dirty filter and insert the new filter. No tools required. I had no problems with these filters. I've been using one of these almost every day for a month and it seems to be working great.
