Works well but after a few weeks algae started growing inside. I cleaned it with a brush, water and bleach. A few days later, no water went through the filter. I removed the internal filter and the water flowed again. I think algae or bleach clogged the micropores in the filter. I emailed the company but they never contacted me. I wrapped the glass part in foil to keep the light out and this prevented the algae from returning. I think I need to buy another internal filter. They're expensive.
