Dear David 671, The UV-C bulb is designed to last for approximately 10,000 hours of use. The UV-C button on the control panel will flash RED when the UV-C bulb burns out and needs to be replaced. The UV-C button will change to blue once the bulb has been replaced. If the filter light remains lit after the filter replacement, please press and hold the ioniser button for 3 seconds until the replace filter light turns off. Kind regards, Team Homedics

Dear Jayee, UV-C, a short wavelength light invisible to the human eye, kills germs, bacteria and viruses by penetrating its DNA, resulting in the microorganism's death or the inability to reproduce. It is completely safe. Do not operate the air purifier without the protective UV-C bulb cover. The Air Purifier AP-T20 Small should be available shortly on our webstore. Kind regards, Team Homedics

Dear Eve ON, This model is suitable for medium-sized rooms up to 84m²/h / 888ft²/h. The suggested room size is 17.2m² / 186 ft². We do not display the figure in metres cubed but this figure can be calculated for any of air purifiers using the room height that we base our calculations on which is 2.43m. Therefore, the purifying area is stated in m2/h based upon a standard ceiling height of 2.43m (8 foot). You would just need to multiply by the room height that the figure is based on. This air purifier will clean the air 4.8 times per hour. If your room area is half the size the air purifier will clean the air once every 30min (or twice an hour). If your room area is one quarter of the size the air purifier will clean the air once every 15min (or four times a hour). How frequently you require your room air to be purified will depend upon the severity of your allergies and environmental factors such as the pollen count on that particular day. We recommend our air purifiers are suitable for Large, Medium and Small room sizes to ensure a constant supply of purified air and to allow for natural air changes such as external ventilation or exiting and entering a room through the door. Kind regards, Team Homedics

Dear Alicez, All Ionisers will generate a small amount of Ozone so if you use the air purifier without the Ioniser turned on then no additional ozone will be created. The ozone is a by-product of the Ioniser which helps remove particles from the air and must not be confused with an Ozone Generator. The amount of ozone created in an air purifier, with an Ioniser turned on, is small, not measurable and is considered safe. Kind regards, Team Homedics
