Are HVAC filters expensive?
The cost of replacement HVAC filters will depend on the type of machine that you have. Air filters come in a number of different sizes and quality types which are suitable for use in a range of different machines. You can buy cheaper filters that are made from disposable fiberglass or you can choose to spend more on high-quality filters for your HVAC machine.
If you want to save money on your air filters, you should try to shop around and search online, as you may be able to get a good deal on some website, or if you buy more than one filter at a time.
