The Truth About HVAC Air Filters You Need to Know


Separating Fact from Fiction in Air Filtration

One of the most persistent myths in the HVAC industry is that the more expensive and thicker your air filter is, the better it will be for your home’s air quality and system performance. At Astro Air Inc., we regularly encounter customers who’ve been misled by this common misconception.

Here’s the reality:

Why Bigger Isn’t Always Better

1. Higher MERV ratings and thicker filters can actually restrict airflow
2. Restricted airflow makes your system work harder
3. This increased strain can lead to higher energy bills
4. Some systems aren’t designed for high-MERV filters

What Really Matters

The key to proper filtration is finding the right balance between:
– Filtration efficiency
– System compatibility
– Regular maintenance
– Proper installation

Best Practices for Air Filtration

We recommend:
– Checking your system’s specifications
– Changing filters every 60-90 days
– Using the correct size filter
– Maintaining consistent maintenance schedules

Remember, the goal isn’t to create an airtight barrier but to maintain healthy air circulation while capturing harmful particles. Your HVAC system needs to breathe to function efficiently.

By understanding these fundamentals, you can make informed decisions about your home’s air filtration needs without falling prey to common misconceptions that could cost you money and efficiency in the long run.
