Buying Guide

When it comes to choosing the best AC furnace air filter, there are several factors to consider. We have tested and used various air filters, and here are some key features to look for:

Filter Type

There are several types of air filters available, including disposable and reusable filters. Disposable filters are typically more affordable and come in a variety of MERV ratings. Reusable filters, on the other hand, are more expensive but can be washed and reused multiple times. Consider your budget and how often you want to replace your air filter when choosing a filter type.

MERV Rating

MERV stands for Minimum Efficiency Reporting Value, and it measures how effectively an air filter can capture particles. The higher the MERV rating, the more efficient the filter is at trapping particles. However, it’s important to note that higher MERV ratings can also restrict airflow, so it’s important to find a balance between efficiency and airflow.

Size

Make sure to choose an air filter that fits your specific AC furnace. A filter that is too small will not provide adequate filtration, while a filter that is too large may not fit properly and could cause airflow issues.

Ease of Replacement

Consider how easy it is to replace your air filter. Some filters require special tools or extensive disassembly of your AC furnace, while others can be easily swapped out with minimal effort.

Price

Air filters can vary greatly in price, so it’s important to find one that fits your budget. However, keep in mind that cheaper filters may not provide the same level of filtration as more expensive options.

By considering these factors, you can choose the best AC furnace air filter for your needs.
