Instead of cleaning old filters, buy a new one & increase both suction & battery life!

My Dyson V-7 would start running for about 5 seconds and then die. Duh, I’ve had it for about 3 years and NEVER cleaned it!!! And I have dogs and a cat, so you know it always fills with hair. So I YouTubed my vac & followed the instructions and WOW!!!! was my vac FILTHY!!!! It was one of those moments where you think, “Man, sometimes I am really dumb.” But in my defense, my wife vacuums so it just didn’t enter my mind. She thought the battery was dying but of course it was way overdue for a cleaning. Really, it was almost completely the filter that was clogged so I rinsed it in hot water and the dirt just kept flowing out of it. I let it dry overnight and the next day my wife vacuumed the about half the house with no problem before the battery ran out. So I ordered these and then replaced the filter and my wife re-vacuumed the WHOLE house before the battery died and needed recharging. And it increased the suction power by about another half. So instead of wasting time cleaning these nasty filters, just replace it!!!
