Do I Need to Replace My Furnace Filter with a Universal Size?

With so many air filters on the market, it's no surprise that one of the most commonly asked questions is “What size air filter do I need?” There are practically thousands of air filters available, making it difficult to find the right one for your air conditioning system. But don't worry, we have your back. It is essential to have the correct dimensions, including the actual and standard sizes, which will depend on the specifications of the air filter. If you need help getting the right dimensions of your air filter to get the right size, contact our experts.

Our professionals in the air conditioning industry will work according to your needs. Plus, air filters come in more than 30 different sizes, so it can be challenging to find the right size for your system. For instance, you'll need to replace a 1-inch air filter every month, while a 4-inch air filter can last six months without needing to replace it. Interestingly, 70% of what Filterbuy sells doesn't fit into the 10 most common air filter sizes.

Let's say you want to replace your air filter but don't know what size you need. Most online air filter sellers have a custom air filter page where you'll find a selection of custom sizes. Replacing your boiler filter regularly is an easy way to maintain good air quality in your home, keep your boiler in good condition, and even save on energy costs. If you have an old filter from your oven on which the dimensions are printed, then determining the size is not a problem.

Even so, understanding the most common air filter size can be tricky if you're not sure what the numbers mean. Even during the hottest months of the year, it is important to regularly check the condition of the boiler filter (and replace it as needed) to keep your family safe and the furnace in good working order.
