Received the Deluxe Sediment Shower Filter with 3 Pcs Water Filters UBS INC from UBS INC CO.,LTD. Since we live on an old farmhouse sourced with well water, I thought it would be a great idea to purchase the filter to purify the shower water. The filter itself is only about 12" long and a few inches wide so it doesn't take up a whole lot of space and while I thought it would look awkward sticking off of the shower head it actually doesn't! Hard to say if it was working while using it but it was really easy to install. It took hubby about 45 minutes to install after reading the enclosed manual. The filter comes with the shower filter a refill cartridge filter, the teflon tape and of course the manual. And it looks like the refill cartridge with original shower filter should be changed every 6 months.
