If you have a home HVAC system, you probably know the importance of regular air filter replacement. But how frequently should you change your air filter? Unfortunately, there is no one-size-fits-all answer to how often you should replace your air filter. This blog post will cover everything you must know about changing your air filter. It will also discuss the factors that dictate how often it is done.

Types of Air Filter for HVAC Systems

When shopping for an HVAC filter, you will have to decide among various options, sizes, and energy efficiency ratings. There are four types of HVAC filters available on the market. Experts at Pioneers Heating and Air, a provider of heating and cooling services, can help you understand your options.

HEPA (High-Efficiency Particulate Air) Filters

HEPA filters are known to offer the highest level of protection. Initially developed for hospitals, this type of filter can trap particles as small as 0.3 microns and catch 99.97% of airborne particles. In addition, HEPA filters are typically found in industrial settings with large volumes of dust particles, such as construction and manufacturing facilities. 

The use of these filters is often very limited in residential HVAC systems. This technology is gaining popularity for use in residential settings. However, an HVAC contractor should still do the modifications and installation to fit a residential HVAC system. Their MERV rating is between 17 and 20.

Reusable and Disposable Filters

In contrast to disposable filters, which you throw away after use, you can clean and reuse reusable filters. Reusable filters are typically more expensive than disposable filters. However, they have a lower MERV rating (between 1 and 4). That means they are more prone to mold or mildew growth.

Flat-Paneled Fiberglass Filters

They are disposable and layered with fiberglass and a metal-reinforcing grate. That makes them durable and able to trap pollutants. But unfortunately, their low MERV rating means they will not significantly improve your home’s air quality.

Pleated Media Filters

Pleated media filters are single-use only. They typically have a MERV rating of 5 to 13. But you can also find high-efficiency versions with MERV ratings ranging from 14 to 16. This type of filter’s design intends to increase surface area, which improves filtration efficiency.

Factors That Affect the Frequency of Changing the Air Filter

The MERV Rating

The minimum efficiency reporting value (MERV) rating of an air filter indicates how effectively the filter prevents dust and other contaminants from passing through the filter and into the air stream. The smaller the particle the air filter can catch, the higher the MERV Rating.

While dense filters with higher MERV ratings last longer, they also restrict the airflow in your home. That means you will have to change the filter more frequently. 

Allergies in the Household

You should change the filters every three to five months if no one in your family suffers from allergies. However, if anyone in the family has light to moderate allergies, change your AC filter more frequently. You can do it every two weeks to prevent clogging and cause symptoms.

Type and Number of Pets

The kind and number of pets in the home necessitates frequent air filter replacement. Households with hypoallergenic pets that do not shed dander can change their air filter every 6 to 12 months. If you have a pet, you should change the AC air filter at least once every 60 days. If you have more than one, you should replace the air filters every 20 to 45 days.

Outdoor Air Quality

If you live in a rural area, the levels of pollution around your house should be low because there are not many vehicles that pollute the air. But if the level of air pollution is high, you should replace your air filter every 30 to 60 days. The same rule applies if you live near a heavily traveled road.
