Are Expensive Air Filters Worth the Cost?

When it comes to air filters, it's important to consider the quality of the filter and the cost. More expensive air filters, such as pleated residential filters, can filter out dust mites, pollen, pet dander, mold, and even bacteria. This can be worth the extra money, especially for people with severe allergies. Washable air filters are also an option, but they have lower MERV ratings and require frequent maintenance.

Household HVAC air filters are rated based on their MERV rating, with most household filters between 1 and 13 (more than 13 are for HEPA filters). It's important to monitor and replace air filters regularly because old, overly dirty filters restrict airflow and keep your oven working longer and longer. Expensive air filters may seem like a luxury, but their role is too important to settle for lower quality filters. Air filters are especially important for those suffering from allergies or respiratory diseases such as asthma and hay fever.

Electronic air filters, such as air purifiers or electrostatic air filters, can also be beneficial. The filter could be in a large inlet vent in the wall or ceiling or directly in the oven blower itself. Blocked filters can cause problems with airflow and increase billing prices. Pleated filters do not have to be changed as often as non-pleated filters, so they can save money in the long run.

Look at the label and note the manufacturer's recommendations for how often you should replace the filter. Your home's air filter blocks problems in the air that a ventilation system can pump from the outside. If you've changed all of your air filters and the air is still moldy or dusty, you could have a crack or break in the return air duct. The unique situation of you and your family definitely determines the way forward, but those with respiratory problems benefit most from using expensive air filters in a heating and cooling system.
