Frequently Asked Questions

Which filter is best for AC?

A pleated filter with a MERV rating of 8 to 13 is ideal for most AC systems. It balances air quality improvement with efficient airflow.

How do I know what air filter to buy for my AC?

Check your current filter’s size label and your system’s manual. Choose a filter that fits your slot and meets your air quality needs (higher MERV for allergies or pets).

Is a thicker air filter better?

Yes, if your system allows it. 2-inch or 4-inch filters trap more particles and last longer, but make sure your AC can handle the extra thickness.

What is the most common type of filter?

The most common is the fiberglass disposable filter. This is due to its low cost. Though pleated filters are becoming more popular for better filtration.

What are the 4 main filter types?

The four main types of air filters are fiberglass filters, which are affordable and basic; pleated filters, which offer better filtration for dust and allergens; electrostatic filters, which use self-charging fibers to attract particles and are often reusable; and HEPA filters, which are the most efficient, capturing up to 99.97% of airborne contaminants.
