Our HEPAS Air Purifier has a Clean Air Delivery Rate (CADR) of 200m3 per hour. A typical HDB bedroom is about 31m3 which means that it can clean the air more than 6x per hour. 

Our air filters are effective for 1500 hours, or 6 months with a recommended daily usage of 8 hours.

Simply wipe or wash the pre-filter every week to maintain your HEPAS Air Purifier.

Naturally, it’s best to place the air purifier in the room where you spend the most time. For most people, this is the bedroom. If you’re allergic to pet dander then you may want to keep your air purifier in the room where your pets spend most of their time. Also, you should not place an air purifier in the corner of a room; it should be placed at least 20cm away from the walls for maximum air flow.
