Can a Furnace Filter be Too Thick? - An Expert's Perspective

When it comes to air filters, thicker may not always be better. While a thicker filter may last longer and provide more filtration, it can also restrict the airflow needed and cause the furnace to work harder. This can worsen efficiency and cause more damage. Most air filters are 1 inch thick, but some systems can accommodate filters 2 to 5 inches thick.

In our tests, we found that the thicker the filter, the better it works and the longer the replacement intervals. This means it's better for you and your heating, ventilation and air conditioning (HVAC) system. An incorrect air filter can reduce HVAC efficiency and increase heating and cooling costs. If the filter is too dense, the heater or air conditioner may need to run longer to counteract increased air resistance.

Too small a filter allows contaminants to build up on critical components, which impairs performance. The right filter will improve your health and comfort without sending utility bills through the roof. The thicker the filter, the more dirt it can hold. And, therefore, you can enjoy a wider range of filter frequency replacement. The HVAC system may struggle to pass air through the air cleaner and use more energy in its attempts.

At the same time, a thicker filter is less restrictive and will allow for better flow of purified air. When you go to a store, you will notice that there are a large number of options for air filters. Reducing the thickness by one inch shouldn't be a big deal; for example, you should be able to use a 4-inch filter instead of a 5-inch filter. On the other hand, 1-inch filters are decent enough to remove typical dust, pet dander, and other particles up to 3 microns in size. Air filters generally come in a range of standard sizes, with some that can be adapted to fit filter housings of different sizes or return air vents. Unfortunately, many people don't remove and clean their filters as often as they really should. Take the guesswork out of buying an oven filter by purchasing replacement air filters from Star Heating & Cooling.

You may think that this type of air filter is not something that you would prefer the air you breathe to flow through. However, there are ways to mess up the job, for example, by buying an incorrectly sized filter or placing it upside down, which can block airflow rather than cleaning it. The life of an air filter depends on several factors, from its size and construction to the air quality conditions in your home and the frequency with which your heating and cooling system operates. If you have an oven in the house, the clogged filter can bother you every 2 to 6 months and request a new replacement. Instead of having extra protection for allergies, you can use your air treatment system if you think a wide-pleated air filter doesn't protect your family enough. In conclusion, when selecting an oven filter for your home or business, make sure that it is not too thick for your HVAC system.
