What You Should Consider Before Buying Your Next Air Filters

September 02, 2019

We all know that we should regularly change our air filters. However, only some of us actually do it. If you are a first-time homebuyer and never had to worry about air filters before, how do you know what type you should choose? There are many options available on the market and finding the one that best suit your needs can sound a daunting task. It is also crucial for you to pick the right one for your home and your family. In this article, we will introduce some of the factors you should consider before buying a home air filter. 


Select the right size

The first step to take is to determine what is the right size for each room in which you want to install your air filters. Air filters and other HVAC products come in different sizes, which differ based on their area and thickness. Air filters work best when they are a tight fit. Pay attention to any gaps around the frame of the filter once you have installed it. This is one of the signs that show you bought the wrong size for your HVAC system. The thickness of air filters can vary from less than 1 inch to more than 4 inches. Most homes have only a 1-inch space for an air filter. Pay attention to what are your system's requirements and look for the right size that fits it.

Understand the differences between each type of home air filter

Many different types of home air filters can offer you various performance levels and maintenance requirements. Generally speaking, air filters are most effective when they are new and clean. However, some of them last longer than others. Among all the types of home filters, here are the most common ones:

-    Disposable fiberglass air filters: this type of air filters only collects bigger particles, like debris, dust, and lint. These air filters usually have a cost of one or two dollars per filter.

-    Disposable pleated air filters: these air filters can collect both larger and smaller particles, like mites and spores. They usually cost a few dollars more than the fiberglass ones and need to be changed more often.

-    Disposable electrostatic air filters: these air filters are made of electrically charged fibers that pick up most of the smaller particles in the air. They do so even more than with larger particles. It is also for this reason that they cost around $10 in a standard size.

-    Permanent electrostatic air filters: this type is also made with fibers like their disposable counterparts. However, these air filters don't collect as many particles as the disposable ones. They are washable, and so you might only have to replace them every 6 to 8 years. They usually cost around $15 or $20 per air filter. You can clean a reusable air filter by rising away all dust particles with a hose outside your home. You should ensure that the air filter is dry before putting it back to your system. 


Your house's indoor air quality is affected by particles such as pet dander, dust, pests – namely rodents and cockroaches – as well as viruses. These types of substances can cause inflammation that in many cases, can develop into severe medical conditions, like pulmonary fibrosis and chronic obstructive pulmonary disease (COPD). Indoor pollution and allergens can aggravate the allergies and asthma of one or more members of your family. That is why, even in this case, prevention is better than cure.
