Everything You Need to Know About Furnace Filters

No matter what type of furnace you have, it's essential to understand the different types of air filters available and how they can affect the performance of your system. HVAC air filters vary in quality and dimensions, and some have features that others don't. Generally, we suggest using the filter that the manufacturer of the air conditioning system recommends connecting to the system. All filters are assigned MERV ratings, ranging from 1 to 20.

MERV stands for Minimum Efficiency Reporting Value.When it comes to oven filters, OEM oven filters are usually designed to the specifications of the oven model or the range of models with which they are combined. Manufacturers are in a great position to design and manufacture air filters that work particularly well with their oven models. In fact, manufacturers recommend using original parts for better performance. However, there are certain scenarios where you can get a much better deal or improved performance if you choose an aftermarket option. An aftermarket furnace filter is one that has been manufactured by a company other than the OEM to strictly meet the operating specifications of the original.

For example, an oven filter measuring 18 x 16 x 1 measures 18 inches long, 16 inches wide, and 1 inch deep. The OEM filter is manufactured by the brand manufacturer, while the generic equivalent (also known as an aftermarket product) is not usually created by that manufacturer, but is manufactured to fit and work as well as the OEM. When it comes to getting the most performance and efficiency out of your furnace, two things are critical: replacing filters and performing regular maintenance. They inhale through the ventilation grilles of the house, drawing air through the ducts and through the heating or cooling source (whether the burners of an oven or the coil of an air conditioner or a heat pump). Ordering from PureFilter can help you receive personalized email reminders on how to replace your boiler filters and get tips on how to maintain healthy indoor air.

Your HVAC professional would install a small cabinet next to the oven or air controller (on the air intake side) to hold the thicker filter. The Minimum Efficiency Report Value (MERV) measures the effectiveness of an oven's air filter in capturing particulate matter. It's essential to remember how often you should change your oven filter and have confidence in buying when you decide to buy. There are also visual cues you can consider when deciding whether to replace your oven filter. When it comes to furnace filters, it's important to understand all your options so you can make an informed decision about which type is best for your needs. OEM filters are designed specifically for each model of furnace, so they provide optimal performance and efficiency.

Aftermarket filters are also designed for specific models but may not provide as much efficiency as OEM filters. Additionally, aftermarket filters may be cheaper than OEM filters but may not last as long. It's important to weigh all these factors when deciding which type of filter is best for your furnace.
