A certain type of pool filter is linked to critical injuries and deaths. The filter is a kettle or canister style, which is two pieces held together by a fastener. During cleaning of the filter, if the cover is not fastened properly, built up air inside the filter can cause it to explode. This leads to the top portion of the filter blowing off and causing injury. The injuries caused by such exploding pool filters include brain injury, loss of an eye, and even death. Since 1982 the Consumer Products Safety Commission has received reports of 22 such incidents, including four deaths. Lawyers who have filed claims regarding exploding pool filters, say that the kettle or canister style filters have a design flaw that allows these incidents.
The death of her husband Jim, from one of these exploding pool filters, led Sue Halverson to start a website on pool safety to inform people about the dangers of kettle or canister style pool filters. Despite the problems with these filters, and the serious injuries caused by them, people are still not aware of the dangers, and so people continue to get hurt. This situation is similar to the MTD snow throwers that have exploding tires. In 2006, over 130,000 MTD snow throwers were recalled due to the danger of their tires exploding while being inflated. However, despite the many serious injuries and the recall, people continue to use the MTD snow throwers and get hurt when the snow thrower tires explode.
