What You Need to Know About HVAC Filters

Last updated 9 months ago

Your HVAC filters are critical for keeping your air conditioner working safely and efficiently. However, many homeowners are still confused when it comes to choosing the right filter. Use this guide to HVAC filters to keep your home cool, air clean, and energy bills low, and always contact Morvent’s One Hour to ensure the filter you choose is the right one for your air conditioner.

Filter Types: HVAC filters come in many types and sizes. It’s important to know which filter is right for your home before purchasing a new replacement. First, take down the measurements of your current filter—these numbers will make it easy to find the right size. In addition, homeowners should choose a filter based on the needs of their household. Pleated filters are extremely popular for their durability and ability to fit almost any vent size. HEPA filters provide extra air filtering performance at a higher cost, while fiberglass vents exist on the low end of the price and quality spectrum.
Performance Ratings: You can compare and contrast HVAC filter performance by noting a product’s Minimum Efficiency Reporting Value (MERV). This unit describes a filter’s ability to trap debris based on the speed of air flow and particle size. The scale runs from one to 16, with 16 being the highest level of protection. Families with allergy problems should invest in filters with MERV rankings between 12 and 16. These provide industry-standard protection against allergenic particulate matter.
Scheduled Replacements: Be sure to change your filters regularly. Filters are poor at filtering debris if the filter itself is covered in dirt and dust. Average pleated filters should be swapped out at least every one to two months, but this schedule depends on a variety of factors. For example, homes with HEPA filters and no pets may not have to charge their filter as often as a household with three dogs and fiberglass filters. It is best to contact your certified HVAC technician to find the correct filter type for your air conditioning unit. An improper filter might not work in your air conditioner and could even permanently damage it beyond repair.
