When it comes to furnace filters, there are a few different types to choose from. Disposable pleats are one of the most popular options, as they have higher MERV ratings and are generally cost-effective. The price of these filters can vary depending on the quality, size, and manufacturer. If you're looking for both low cost and high quality, pleated furnace filters are the best choice for your system.
It's important to note that just because a one-inch thick disposable filter is good, it doesn't mean that a six-inch deep media filter is six times better. Replacing the wrong furnace filters can damage your HVAC system and the indoor air quality (IAQ) of your home. Your system was carefully balanced by trained HVAC technicians, and airflow velocity is part of that balance. Adding a coarser filter can alter this balance, so if you haven't changed your filter in a while and notice a lot of hair or dust around the filter opening, it's recommended that you vacuum around the outside of the furnace and into the filter opening before replacing it.
Additionally, filters with very high MERV ratings can restrict airflow too much for your furnace to operate normally. Furnace filters are an important part of keeping your home warm while also maintaining good air quality. It's worth noting that some homes use a single filtration system or type of air filter for both hot and cold air. While both air filters and furnace filters serve the same purpose (cleaning the air in your home), there are some key differences between them such as filter location, service life, filtration level, and cost. To make sure you're using a safe filter for your furnace, it's best to confirm what your MERV rating converts to.
To replace your filter, open the door to the filter compartment (which will be between the air inlet and the furnace itself) and slide out the old filter before disposing of it properly (it will be dusty, so try to place it in a bag as quickly and gently as possible).If you're unsure about which furnace filter is best for your home needs, contact an expert at Appleby Systems for more information.
