How to Choose a Furnace Filter

Are you staring at the row of air filters in a home improvement store and feeling confused about which one is the best fit for your furnace? Finding the ideal air filter can feel like searching for a needle in a haystack. But the team at Rooter Hero Plumbing & Air is here to help. Our specialists offer air conditioning repair, heating replacement, and furnace repair, so we understand the details about air filter options. Keep reading to learn about the different types of air filters so you can find out which one will best fit your needs.


Fiberglass filters, which are often seen as the entry-level option, are your go-to for basic furnace needs. These filters are made from spun fiberglass material and are designed to catch large particles like dust, lint, and debris, which prevents them from entering your furnace system. While their filtration capabilities might not catch the smallest particles, they offer a cost-effective solution for those prioritizing affordability and basic protection.

Pleated Cotton

Step up your air filtration game with pleated cotton filters. These filters use a denser material, offering a higher level of efficiency compared to their fiberglass counterparts. The pleats increase the surface area, enabling the filter to trap smaller particles such as pollen, mold spores, and pet dander. They are ideal for households seeking improved air quality without a hefty price tag and offer the right balance between performance and cost.


Electrostatic filters bring a touch of technology to air filtration. These innovative filters use an electrostatic charge to attract and trap particles. Available in both disposable and washable versions, they offer flexibility for those committed to reducing waste. Electrostatic filters excel in capturing smoke, bacteria, and virus particles, making them a fantastic choice for homes with pets, smokers, or individuals with allergies.

HEPA Filters

HEPA, or High Efficiency Particulate Air filters, represent the pinnacle of air filtration technology. Meeting strict standards, these filters capture at least 99.97% of particles that are 0.3 microns in diameter. HEPA filters are unparalleled in their ability to purify air, making them ideal for those requiring the highest level of air quality, including homes with individuals suffering from severe allergies or respiratory conditions.

Polarized Air Cleaners

These devices use an electrical charge to create a polarized field, capturing particles far smaller than traditional filters can manage. While not a filter in the conventional sense, they offer a complementary solution that can drastically reduce airborne contaminants, including viruses, bacteria, and ultra-fine particles. For those seeking the ultimate in home air quality, incorporating a polarized air cleaner into your system is the way to go.
