According to my experience, these washable filters are a fantastic investment for any home and kitchen .They fit perfectly in my vacuum and are incredibly easy to clean. Not only are they cheaper than continually buying disposable filters, but they also last much longer. The colorful rainbow design adds a bit of fun to an otherwise mundane chore. The only con I can think of is that they may appear less durable than their disposable counterparts but I have yet to experience any issues..
