The Truth About HVAC Air Filters: Debunking the Monthly Replacement Myth

Common HVAC Misconceptions

One of the most persistent myths in the HVAC industry is that you absolutely must replace your air filter every single month, no exceptions. At Conway Air Conditioning, we’re committed to providing honest, factual information to our South Carolina customers, and it’s time to set the record straight about air filter replacement schedules.

The Reality of Filter Replacement

The truth is that filter replacement frequency depends on several factors:

• Household size
• Number of pets
• Local air quality
• Filter type and quality
• System usage patterns

While some households might indeed need monthly replacements, others can safely go 3-4 months between changes. High-quality pleated filters typically last longer than basic fiberglass ones.

How to Know When It’s Time

Instead of blindly following a calendar-based schedule, we recommend:

• Visually inspecting your filter every month
• Changing it when it appears dirty or clogged
• Being more vigilant during heavy-use seasons
• Following manufacturer specifications

Remember, unnecessarily frequent filter changes aren’t just wasteful – they’re costly too. By understanding your specific needs, you can maintain optimal system performance while avoiding unnecessary expense.
