PTC heaters themselves do not produce allergens, but if not properly maintained, they can accumulate dust and other particles, which can aggravate allergies in some people. Regular cleaning of the heater can help reduce this risk.

PTC heaters are generally quieter than traditional heaters because they do not have a noisy fan. However, the level of noise can vary depending on the model and the speed of the heater. Most PTC heaters operate quietly enough for use in bedrooms or offices.

PTC heaters are known for their durability and long lifespan. With proper maintenance, a PTC heater can last for several years. The ceramic element in PTC heaters is resistant to wear and tear, making them a reliable choice for long-term use.

PTC heaters can be used alongside other heating systems, such as central heating or underfloor heating, to provide additional warmth. They can also be used to supplement the heat in areas where the primary heating system is insufficient.

PTC heaters are generally considered safe for most people. However, some people may experience discomfort from the direct infrared radiation emitted by radiant PTC heaters, especially if they have sensitive skin or are prone to dryness. Using a humidifier or avoiding prolonged exposure to the heater can help mitigate these concerns.
