Types of HVAC Filters

Clogged filters can limit the airflow of your HVAC system, causing it to work harder than it should just to maintain the temperature you set on your thermostat. This can affect its life span quite significantly. Poor air filtration is also detrimental to your indoor air quality, and can even increase the amount of humidity inside your home. This is why regular filter changes must be performed at least once every 90 days.

Types of HVAC Filters

When shopping for a filter, however, it’s easy to get overwhelmed by the dozens of options available to you. Let our HVAC specialists at Kemnitz share with you a few of the most basic types of HVAC filters so you can choose the right one for your home.

Fiberglass Filters

Disposable fiberglass filters are a double-edged sword. On the one hand, they’re the most affordable type of filter available. On they other, they often have the lowest MERV ratings, which are a measure of filter efficiency. The filtering device itself is comprised of fiberglass layers framed by cardboard and plastic, and can last a little over 30 days.

HEPA Filters

HEPA stands for High-Efficiency Particulate Air, and HEPA filters are the polar opposite of fiberglass filters when it comes to quality. These filters boast some of the industry’s highest MERV ratings, which means they’re very effective at stopping the spread of not only dust, dirt and dander, but also harmful bacteria and viruses. Their efficiency comes at a price, however, as most HEPA filters cost up to 4 times as much as their alternatives.

Reusable Filters

Reusable filters offer a reasonable middle ground between the previous two types. One advantage to this type of filter is that they can be cleaned and reused. However, be cautious about using newly-washed filters, because any moisture left in them will create an ideal environment for the spread and growth of mold colonies.
