Review on Arm Hammer ARMCW Eureka Allergen by Tim Olson

I didn't even know I had to replace this thing. I've been using the original filter for two to three years and have noticed a significant drop in suction power. I thought the vacuum cleaner was broken but after buying and installing this filter I can say it's like a new vacuum cleaner. Great suction again. It's good that I know what to do in the future. I recommend!
