Regularly replacing indoor air filters is crucial to ensuring the optimal performance of any home HVAC system. Changing indoor air filters, after all, is relatively easy for any ordinary homeowner. Besides, it does not require specialized tools.

Some of the benefits of regularly replacing indoor air filters include:

  • Improved energy efficiency. The HVAC system does not use up too much energy to supply cool air throughout the house, since the HVAC is not burdened by restricted airflow.
  • Better indoor air quality: Less pollen, dander, dust, and filth circulate at home as these get trapped in the filters.
  • Longer lifespan for the HVAC system since routine filter replacement prevents excessive wear and tear on the system’s mechanical parts, this will help to reduce ac repair needs for your home.
  • Regularly replacing indoor air filters also helps avert inconvenient AC and furnace repair needs.

When to change AC filters?

Air conditioning experts recommend that homeowners change AC or furnace filters every three months. Homes with pets however must replace their indoor air filters more often like every 60 days as dander tend to accumulate much faster. The same two-month recommendation also goes for homes with family members that have allergies or other health issues that make them sensitive to indoor air pollutants.

To make filter replacement much more convenient and easier, order a year-long supply online so that it is delivered right into the house. Set a phone calendar reminder every three months, encode the reminder in a printed physical calendar, and remember that filters need replacement every time the seasons change!

How to get started in replacing an indoor AC filter?

Homeowners need not worry about AC filter replacement taking too much time. Changing filters takes only 10 minutes, which is why there is no reason to skip this chore given the many benefits mentioned earlier in this article. So, as long as the replacement filters are on hand, then the homeowner can replace the filters anytime!

What to prepare when replacing indoor air filters?

  • Replacing indoor air filters is not rocket science, and it does not require special tools or equipment. Just prepare the following:
  • Any disposable air filter with a MERV rating between 8 to 11. Multi-layer, reusable filters are not recommended as they take too much work to get cleaned for reuse. It is stressful and inconvenient.
  • Any home vacuum cleaner, or if there is none, a clean, wet rag will do.
  • A garbage bag that could fit the old filter
  • A marker to note the date of installation

Step #1: Find the Air Vents

The air filters to replace are the return air vents. These are usually located on walls and are much bigger than supply vents that blow in cold air. Most centralized air conditioning systems do have at least one return air vent, and so homeowners should prepare to replace more than one per season. If there seems to be no air vent in any of the walls, then they must have been installed in the ceiling.

Step #2: Clean the cover

The air vent covers could become too dusty especially if the filters have yet to be replaced after more than three months. Vacuum clean the filter cover, or in the absence of a vacuum, one could just clean the cover with a wet rag to get all the dust out. Don’t forget to check your hvac drain line too for any clogs while you’re cleaning the cover.

Step #3: Open or remove the cover, and remove the existing filter

Remove the filter, and immediately put it inside a garbage bag. Dispose of used filters right away as it harbors impurities that could just circulate back into the indoor air. Never shake them or take them around the house.

Step #4: Mark the new installation date

Install the new air conditioning filter, and make sure to note its installation date. Noting down the installation date in the space provided or if there is none, within the borders of the filter, could help in monitoring the next filter replacement schedule.

Step #5: Double-check the air flow indicator

Make sure that the filter is installed in the right direction. To double-check, take a look at the airflow direction indicator that indicates a front-to-back installation given that supply vents suck in air from inside the house.

Most home HVAC experts do not recommend the use of higher MERV air filters since it could unduly burden the system. If the HVAC could not take in enough air, then the system may break down in time. If the homeowner is concerned about indoor air quality, allergic triggers, as well as mold infestation then other possible workarounds are more effective and will not burden the AC system.

These options include active purification systems such as whole-home air purification systems, installation of media filters, and use of Ultraviolet (UV) lights.

Step #6: Install the air filter and replace or close the air vent cover

Install the new filter, and make sure that it fully covers the vent. After correctly installing the air filter, close the air vent cover carefully. Everything is all set now! What is left to do is wait for another three months to replace the filter.
