Common HVAC Filter Myths That Could Cost You Money

The Truth About HVAC Air Filters That Every Homeowner Should Know
One of the most persistent myths in home heating and cooling maintenance is that the more expensive the air filter, the better it is for your HVAC system. Let’s clear the air about this and other common misconceptions that might be affecting your home’s comfort and your wallet.
Myth #1: The More Expensive Filter is Always Better
Many homeowners believe that purchasing the highest-rated MERV (Minimum Efficiency Reporting Value) filter will provide the best air quality and system performance. However, using a filter with too high a MERV rating can actually restrict airflow and force your system to work harder, potentially leading to increased energy costs and premature wear.
Common Filter Misconceptions:
- All filters need changing every 30 days (False)
- Fiberglass filters are worthless (False)
- You can wash and reuse disposable filters (False)
- Running the system without a filter is okay for a short time (False)
The Real Facts:
1. Filter replacement frequency depends on various factors including:
– Pet ownership
– Number of occupants
– Local air quality
– Season of the year
2. Basic fiberglass filters can be adequate for many homes and protect your HVAC equipment effectively when changed regularly.
3. The best filter choice depends on your specific needs and system specifications.
Remember, the goal is to find the right balance between air filtration and system efficiency. If you’re unsure about which filter type is best for your system, consulting with a professional HVAC technician can help you make the right choice for your home’s specific needs.
Regular maintenance and proper filter selection are key to maintaining optimal HVAC performance and ensuring healthy indoor air quality throughout the Pacific Northwest’s varying seasons.
