Let’s Clear the Air About HVAC Filters
One of the most persistent myths in home comfort is that the more expensive the air filter, the better it is for your HVAC system. As heating and cooling professionals, we at Kelvin Comfort Air Conditioning regularly encounter misconceptions that could be costing homeowners unnecessary money and potentially damaging their systems.
Here are the top filter myths we need to address:
Myth #1: Higher MERV Ratings Are Always Better
While MERV (Minimum Efficiency Reporting Value) ratings measure a filter’s effectiveness at capturing particles, using the highest-rated filter isn’t always ideal. Some systems aren’t designed to handle the restricted airflow that comes with high-MERV filters, which can lead to reduced efficiency and potential system damage.
Myth #2: Change Filters Every 30 Days No Matter What
The one-month rule isn’t universal. Filter replacement frequency depends on:
• Number of occupants
• Presence of pets
• Local air quality
• System usage
• Filter type
Myth #3: Washable Filters Save Money
Washable filters might seem cost-effective, but they often don’t provide the same level of filtration as disposable ones and can harbor moisture and bacteria if not dried properly.
The Truth About Filters
The best filter choice depends on your specific system specifications and household needs. Regular maintenance and proper filter selection are crucial for optimal system performance.
Remember, choosing the right filter is about finding the balance between air quality and system efficiency. When in doubt, consult with a professional who can evaluate your specific needs and system requirements.
By understanding these facts, you can make informed decisions about your HVAC maintenance and potentially save money while maintaining optimal indoor air quality.
