The process of cooling and heating your home represents almost 50% of your energy costs, which is just one reason why it is vital that you take good care of your HVAC system.
Knowing how to change a central air conditioner filter can make it easier to keep up with basic maintenance. Wondering how often to change an air filter in a house? To ensure your air conditioning system will last for many years to come, it is recommended you change the filter out every 30 to 90 days, depending on your filter type. Performing this regular task will help your system run more efficiently, prevent costly repairs and keep your HVAC running longer.
There are many types of air filters for HVAC system out on the market with various pros and cons. Which is the most suitable for your home? Let’s review each type of filter and how to best care for them.
Washable Air Filters
Permanent air filters are also known as electrostatic or washable filters. The static electricity present in these components attracts up to 94 percent of the pollutants in the air.
Generally, it is recommended that you wash these filters about every three months, a process that only takes a few minutes. Warm water is all that is necessary to clean them.
With regular cleaning, washable filters usually last about five years, which means their initial cost will be recouped over time.
Fiberglass Air Filters
Certain kinds of air filters are made of fiberglass. These filters are relatively inexpensive and work well to eliminate large contaminant particles from the air.
Fiberglass filters are often found in homes without pets or where the occupants don’t have allergies or health conditions, since these filters only provide basic protection for large particles.
Since fiberglass filters don’t protect against smaller contaminants, these filters are not suitable for those who suffer from allergies. Fiberglass air filters typically require replacement every month.
Pleated Air Filters
Pleated air filters are widely used in homes across America and consist of higher air resistance combined with a pleated V-shape. The pleats on these filters create a larger surface area to filtrate the air in your house. Pleated filters are relatively inexpensive and come in a wide variety of sizes that fit most HVAC systems. This type of air filters start under $10 and typically last up to four months.
High-Efficiency Air Filters
High-efficiency air filters, or HEPA filters, are effective in removing both large and small contaminants from indoor air. Small contaminants HEPA filters remove include bacteria, different types of pollen and mold.
HEPA filters are the best choice for those who are looking to protect a home from allergens that might cause reactions because of the filter’s ability to catch particles which are as small as 0.3 microns big. HEPA filters run a bit more, starting at a little more than $10, but they last on average a little longer—around six months.
