The perfect HEPA air cleaner.
We've been using a Hathaspace HEPA air cleaner for 3 years and it works perfectly to keep our home's air clean. It's quiet and efficient. When we cook we can see how much cooking puts particles into the air and how rapidly the air cleaner cleans the air. I appreciate having the automatic filter replacement program, since it's easy to forget when to change the filter. We also routinely clean out the sensor once a month. We strongly recommend this HEPA air cleaner.
