When it comes to air source heat pump water heaters, there are a number of different air filters that are used. It’s important to understand the differences between them, so you can make sure you’re getting the right one for your home.
The most common type of air filter is the pre-filter. This filters out larger particles like dust and dirt, which helps keep the system running more efficiently. It also helps to reduce the risk of damage to other components in the system. Pre-filters should be changed regularly, usually every three months or so.
Another popular type is a carbon filter, which is used to remove odours and other organic compounds from the air before it enters the system. Carbon filters can help improve indoor air quality by removing volatile organic compounds (VOCs) from the air. They should be changed regularly too, usually about every six months or so depending on usage.
Finally, there’s a high efficiency particulate air (HEPA) filter. These are designed to remove tiny particles from the air, such as pollen and smoke particles that can cause allergies and respiratory problems. HEPA filters can also help improve indoor air quality by reducing airborne contaminants like mould spores and bacteria. These filters should be changed every year or two depending on usage.
These are some of the different types of air filters that are used in air source heat pump water heaters. Understanding what they do will help you choose the right one for your home and keep your system running efficiently and safely for longer!
