Four packs of filters arrived on time and fit my Eureka Maxima model #4711. The vacuum requires a dust filter (DCF-4). Vacuumed today a week after my last use and it picked up a lot of dust that was easy to clean off the filter. I used a toothbrush and air in a can after the first use so I didn't have to wash it too often. Each filter came in its own small plastic bag in a separate box. The plastic bag was not sealed but the top of the bag was tucked into the filter. I would prefer a sealed bag or tie so nothing gets inside. The bottom of one of the boxes was not sealed properly, but the product was not damaged. The manual I have from Eureka is 7 years old and the listed price for 1 filter is $19.99 plus $9.75 shipping and handling. Revain certainly offers much better savings.
