FAQs
A 5 inch air filter maintains superior air quality indoors and functions as a protective barrier within your HVAC system, removing allergens, pollutants, and dust before they spread through your HVAC system. Its pleats increase filtration, circulating purified air throughout your living space.
Replacing a 5 inch furnace filter regularly will make your HVAC system work more efficiently and improve your overall indoor air quality.. Replace it every 6 to 12 months, or whenever it gets clogged or dirty. If you frequently run your HVAC system, have pets, or have an excessive amount of pollutants in your home, you might want to consider replacing your furnace filter more frequently to ensure optimal filtration.
Engineered for superior filtration, a 5 inch AC filter will trap fine particles as small as 0.03 microns when they have 8,11, or 13 MERV ratings. They reduce dust and debris from accumulating and clogging your HVAC system, to safeguard it while circulating cleaner air. Investing in high-efficiency 5 inch AC filters means you’re making a wise choice for system reliability, to achieve a healthier indoor environment.
Potential cost savings add up over time when you regularly replace your 5 inch filter, because it lowers energy consumption costs up to 15%. The filter design improves airflow and reduces the demand for energy, making your HVAC system work more efficiently while reducing power costs.
Examine the dimensions of the filter housing slot in your unit to see if it can support a 5 inch thick furnace filter. If you’re not sure after checking it, read your system manual or measure the slot. If your current filter is thinner, you might need an adapter to accommodate a thicker one. Consult with an HVAC professional technician to ensure that using a thicker one won't restrict airflow.
HVAC industry professionals advise you to use an air filter with a MERV 11 or MERV 13 rating, but your choice may depend on how much filtration you need and if it's compatible with your HVAC system. Air filters rated with MERV 11 or 13 will protect your home from microscopic bacteria and airborne contaminants. MERV 8 filters won’t filter bacteria or fine particles as well as MERV 11 or MERV 14 filters do, but they do provide moderate filtration.
If you suffer from allergy symptoms or sensitivities, using a 5 inch furnace filter can offer relief because it will keep allergens from circulating in your home. Filters with MERV ratings of 11 or 13 can capture microscopic particles like pollen, dust mites, pet dander, and mold spores that can significantly affect your breathing. 5 inch filters are designed to integrate with your HVAC system and achieve whole-home filtration, instead of only impacting smaller rooms like small filters do. If you pair this filter with consistent deep cleaning and hypoallergenic bed linens, it will maximize your home’s protection against unhealthy allergens and ensure your air is more breathable.
A standard HVAC filter slot is intended to house a filter that is 1 to 4 inches thick, so 5 inch filters might not fit properly unless you’re able to use a housing adapter or the slot dimension can be modified. Review the specifications of your HVAC unit and measure the housing slot to confirm compatibility if you’re planning to use a thicker filter. Ask an HVAC technician to help you determine if your slot needs modifications if you want to use a thicker 5 inch filter.
Before you install a 5 inch air filter, shut off your HVAC unit. Find the filter compartment, open the access panel, remove the previous one, and check the airflow direction. Install the new filter with its arrows pointing in the same direction as the older filter, ensuring it's snug. Close the access panel and restart your HVAC unit, then confirm its functioning correctly.
Not changing out your air filter when it is dirty or clogged can lead to excess buildup, circulate unhealthy air, and cause your HVAC system to break down or become damaged. It could lead to expensive repair bills if your HVAC system is forced to work harder. Improper filtration may cause more pollutants to spread through your living space, increasing the risk of respiratory illness or additional health issues. Routinely changing your air filter ensures system longevity and keeps clean air circulating.
