Where do I find my system鈥檚 filters?
Depending on the type of system, you may have one or more filters, found in different places for different systems.
鈥淎 decentralized, ductless system like a mini-split heat pump will have a filter for each head in the house, so you need to check each one,鈥� Milani says. 鈥淎 central system like a furnace or outdoor heat pump usually just has one filter in the central unit.鈥�
What kind of filters do I need?
HVAC filters are rated using the system, a way of indicating how efficiently an air filter captures particles of various sizes. MERV ratings are represented by a number ranging from 1 to 16, with MERV-16 providing the most protection and MERV-1 providing the least.
鈥淧articles are measured in microns, allowing you to choose the right level for your needs,鈥� Milani says. 鈥淵ou can also use HEPA filters, with different levels of filtration, from an average type for dust and mites, to a more more granular filter that can take care of bacteria and antigens. You can also install an air purifier attachment with the standard filter, for a more robust filter capable of trapping some viruses.
鈥淭hey also come in different types and sizes, depending on the manufacturer, so be sure to check your system specifications.鈥�
Milani points out that beyond checking filters, all HVAC systems also require regular safety checks.
鈥淲hether it鈥檚 a gas-fired system or an air conditioner, you should call a professional regularly to check for gas and coolant leaks, or other issues.鈥�
