Review on Funmit HEPA Filter Replacement Set for Dyson DC41 DC65 DC66 UP20 Vacuums - Compare to Part # 920769-01 & 920640-01 by Beth Smith

The filters arrived quickly, they fit as expected and the suction has definitely improved in my DC65. The old disc filter I replaced was really dirty so I'm biased to thinking that was the biggest impact. To be honest the suction power is close if not at the same level as it was a few years ago when I got my first vacuum. On some carpets you need a little more muscle power because of the strong suction power.
