Brand Name : Crucial Vacuum


Have you started sneezing when you vacuum? Does the simple chore make you cough or bring a tear to your eye? That might be because your filters need replaced. If you go too long without a filter swap, eventually your filters are going to clog and get little tears, reducing their effectiveness. One thing you can do to help is ensure you're changing your filters in the recommended time frame, usually around every four to six months for vacuum filters. These filters are washable, which mean you can rinse them with cool water to remove the larger bits and help keep them working better for longer. Rinse them every couple of weeks and air dry them before you reinstall them. This filter kit contains foam filter and felt filter.
