Maintaining a clean and efficient HVAC system is essential for a comfortable and healthy home environment. One critical component of this maintenance is the HVAC filter. This guide will provide detailed information on how often to change your HVAC filter, the best types of filters to use, how to install them correctly, and additional ways to improve indoor air quality.
How Often Should I Change My HVAC Filter?
The frequency of changing your HVAC filter depends on several factors, including the filter size, the type of filter, the household environment, and the HVAC usage. Here are some guidelines to help you determine the best schedule for your home:
1. Filter Size: Larger filters generally have a longer lifespan. For example, a 1 inch filter might need to be changed every 1-3 months, a 2 inch filter every 2-6 months while a 4 inch filter could last 6-12 months.
2. Household Environment: Homes with pets, smokers, or residents with allergies should change filters more frequently. Pet dander, smoke particles, and allergens can quickly clog a filter.
3. HVAC Usage: During peak heating or cooling seasons, the HVAC system runs more frequently, necessitating more frequent filter changes.
To decide the optimal time to change your filter, regularly inspect it for visible dirt and reduced airflow. You can hold it up to the light and if you can easily see the light shining through it should not be restrictive. If the filter appears dirty or clogged, it’s time for a replacement.
What Type of Filter Should I Get?
Choosing the right filter is crucial for balancing air quality and system efficiency. At ComfortX HVAC, we recommend using a MERV 8 pleated filter for most households. Here’s why:
1. Efficiency: MERV 8 filters capture a significant amount of airborne particles without overly restricting airflow. Higher MERV ratings, while more effective at filtering small particles, can reduce system efficiency and increase energy costs.
2. Balanced Performance: Filters with lower MERV ratings may not effectively capture dust, pollen, and other allergens. MERV 8 provides a good balance, ensuring clean air without straining the HVAC system. This allows particles to travel to the evaporative coil restricting airflow, performance, and efficiency.
Are Washable Filters Good?
Washable filters are generally not recommended unless they are high-quality, electrically charged filters like the Accucleans we work with. Standard washable filters tend to have lower MERV ratings and may not effectively capture fine particles. Additionally, they require thorough cleaning and drying to avoid mold and mildew growth. They are also almost impossible to completely clean after some time and start to deteriorate with many washes.
How to Tell Which Way to Put the Filter
Correctly installing your HVAC filter is essential for proper system function. Here’s how to determine the airflow direction and ensure proper installation:
1. Airflow Direction: HVAC filters have an arrow indicating the direction of airflow. This arrow should point towards the HVAC system, indicating the air is being pulled through the filter and into the system.
2. Installation in Ceiling/Wall Units: For ceiling or wall-mounted units, ensure the arrow points inward, towards the air handler or furnace. For example once the grate is open you would install the filter with the arrow pointing into the hole.
3. Before the Air Handler/Furnace: For filters installed right before or beneath the air handler or furnace, the arrow should point towards the unit.
Ways to Further Clean Your Air
Beyond regular filter changes, additional products can significantly improve indoor air quality. At ComfortX HVAC, we offer advanced air cleaning solutions like the AccuClean Electric Air Cleaner and RGF’s REME HALO LED.
1. AccuClean Electric Air Cleaner: This system uses advanced filtration technology to remove up to 99.98% of airborne particles, including dust, pollen, and bacteria. It’s especially beneficial for individuals with allergies or asthma. They can however be difficult to arrange in some situations depending on the space.
2. REME HALO LED: This in-duct air purifier uses UV-C light and ionization to reduce airborne and surface contaminants such as viruses, bacteria, mold spores, and odors.They are equipped with a self-cleaning ion generator designed to reduce airborne particulate by coagulating ultrafine particles making your existing filter more effective. It’s a powerful solution for maintaining a healthy home environment and is applicable to almost every type of system.
