Replace Your 30x30x1 Air Filter Regularly

Keeping your 30x30x1 air filter clean and up to date is one of the easiest ways to maintain a healthier indoor environment and protect your HVAC system from unnecessary strain. 

Dirty filters can clog, especially in high-traffic commercial spaces or homes with pets. When the filter is past its lifespan, it can allow more dust and allergens into your space. A clean filter helps trap dust, pollen, pet dander, and other particles, improving air quality and reducing respiratory irritation.

Clean filters also improve system performance. When a clogged filter restricts airflow, your HVAC unit has to work harder to heat or cool your space. This can shorten its lifespan and increase your energy bills.

To stay ahead of maintenance issues, check out our complete guide on how often you really need to change your air filter based on usage and environment.

Next, choose the right MERV rating for your space.

  • MERV 8 is great for general dust and debris
  • MERV 11 adds protection from allergens
  • MERV 13 targets finer particles like smoke, bacteria, and pollen

Pleated Vs Fiberglass?

A pleated air filter's media follows a folding pattern, which creates increased surface area, and in turn, allows more air flow while maintaining the quality of air. On the other hand, a fiberglass filter has a minimal surface area, and furnace filters out larger particles
like dust and lint and is not very effective.

Pleated Filter
Pleated Filter
  • Larger surface area captures more particles
  • Less replacement frequency
  • Average lifespans of 3-12 months
  • Higher MERV rating 8-13
  • Higher quality, sturdy and durable
Fiberglass Filter
Fiberglass Filter
  • Smaller surface area captures less particles
  • More replacement frequency
  • Average lifespans of 1-2 months
  • Lower MERV rating 2-4
  • Lower quality, flimsy and porous

How often should you change your filter?

Filter King AC & furnace filters aren’t the typical fiberglass filters that need to be replaced every 30 days. Our filters can typically be used for 3 months without change.

You should change your filter more frequently if you notice:

  • Household dust build-up
  • Higher energy bills
  • The air isn’t cooling as is used to
  • There’s more dust near the air vents
  • A dirty filter surface
  • Burning smells near your HVAC system

How to install your air filter?

Installation couldn't be easier. Every filter features an airflow arrow printed on its side. It's crucial to align this arrow with the direction of the air when inserting the filter into your furnace or central air return ducts.

FAQs

Not necessarily. Filters labeled with identical dimensions can still differ in quality, materials, and efficiency ratings (like MERV ratings). Always check specifics to ensure you're choosing the best option for your needs.

Typically, MERV 8-13 are suitable for residential use, balancing efficiency and airflow.

Thicker filters can restrict airflow slightly, but usually have larger surface areas to offset this.

Choose a MERV rating suitable for your HVAC system; usually MERV 8-11 provides good balance.

Filters with activated carbon or charcoal can reduce pet odors effectively.
