I am currently designing a air purification unit for domestic use (my major uni project), it is hoped to help clean the air for sufferers of asthma and severe allergies. I would like to make the unit portable so that it could be transported easly from the bedroom (for night use) to the living area of the house (for the day). If anybody has any suggestions on aspects of importance they would hypothetically want from the system it would be really appreciated. For example, would it be useful for the device to display how much air is in the room and a percentage countdown of how much of that air is cleaned over time? Other areas id like to look at are aesthetics, portability, wht feedback is required for the operator/asthma sufferer?
