This reusable vacuum filter stopper has been a game changer for my home and kitchen. It's MADE vacuuming so much easier and more efficient. The stopper fits perfectly and securely in my vacuum's filter chamber, keeping the filter clean and prolonging its lifespan... The best part? It's reusable so i don't have to keep buying disposable filters. The only con is that it took a few tries to figure out how to position it properly, but once I got the hang of it, it was smooth sailing..
