Tips for Choosing a Quality Furnace Filter

Cleaning Your Furnace Filter Anywhere From Every 1 To 3 Months

Your furnace and AC filter play an important role in promoting better indoor air quality for your home and helping your air conditioning unit run well. Air conditioning mechanics in Portland advise changing or cleaning your furnace filter anywhere from every 1 to 3 months, depending on factors like the type of unit that you have, how many people and pets live in your home, and how often you run the system.

When shopping for a furnace filter, you’ll find that they come not only in many sizes but in a wide range of prices, as well. While you might be tempted to reach for the filter that has the lowest price in the size that you need, this may not be your best option. Higher quality filters can require less frequent replacement, and they can also do a better job of cleaning your home’s air.

To choose a quality furnace filter, look at the MERV rating of each product. This rating indicates how effectively the filter removes particles from the air, and a higher number correlates with a better filter. High-quality AC filters achieve MERV ratings of around 12, while most inexpensive ones are typically rated MERV 4.
