Similar to Dyson brands, these filters are made of high quality material and are reusable. I found it a bit tricky to install, but other than that it works great. For the price I paid they are good enough and do the job. Don't spend too much money on branded products every now and then. The quality of the product is good and works great as a Dyson brand. In terms of air quality, I see no difference to Dyson brand filters. The quality and performance of the filters is similar to branded filters.
