What is the Best Air Filter for Your HVAC System?

When it comes to selecting the right air filter for your heating, ventilation and air conditioning (HVAC) system, it's important to consider the thickness of the filter, the MERV rating, and the type of filter. 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 HVAC system.

However, when you select the right filter for your HVAC system, higher isn't always better. Using an air filter with a MERV rating higher than recommended by the manufacturer of your oven or air conditioner may impair its performance. Most disposable filters for home air conditioning systems are fiberglass. Polyester filters, although more expensive, offer an improved ability to stop dust and allergens.

Pleated designs tend to have higher MERV ratings. Once you know the highest level of MERV your oven can handle, it's time to choose the best filter for you and your home. But when it comes time to replace it, does it really matter what type of filter you choose? Aren't all filters basically the same? This fine level of filtration provides more resistance to airflow, which can put a residential HVAC system to the test. If you have asthma or allergy at home, you'll want to change your HVAC filter every six weeks to maintain excellent indoor air quality.

The starting price for an electronic filter can be high, but it's perfect for people who don't change their filters once a month as recommended because they can be changed annually. There is another type of filter (a high-efficiency pleat with a MERV of 14-20), but most household ovens cannot withstand blowing air through this filter. The first thing to consider when buying a new filter for your HVAC system is the filter size. Most HVAC units are forced air systems; they literally force air through a filter into the rest of the house to cool or heat internal rooms.

Although fewer particles pass through the filter, your HVAC system has to work harder to force air through the filter and into the house. Regularly replacing your air filter is the best thing you can do to keep your HVAC system running. With the electrostatic filter, you could take a bigger blow to your pocket, since this type of filter is more expensive than a fiberglass filter and a pleated filter. But how often do you need to change the air filter? How often do you need to change the oven filter? Well, it depends. It can be difficult to choose which air filter is best for you, especially when there are so many different options.

The filters themselves vary in price, but the actual electronic filter housing must be installed before purchasing an electronic media filter. If you want to buy a higher MERV filter than recommended by the manufacturer, you risk burning the blower and heat exchanger of your HVAC unit.
