While return vents don't always require filters, adding them provides additional filtration, improving indoor air quality and keeping dirt and debris out of your system.
Putting filters in air return vents is generally not recommended for several reasons: Airflow Restriction: Return vents are designed to allow air to flow back to the HVAC system. Adding filters can restrict airflow, leading to reduced efficiency and potential strain on the system.
Use your vacuum cleaner's hose attachment to clean the return's interior and surrounding areas. Then use a soft-bristled brush to clean the grille thoroughly. Wipe down the grille with your microfiber cloth and cleaning solution before reinstalling.
You need 1 “set” of filters, 1 filters air intake to the blower unit & 1 on the return to filter house air.
Yes, you can put filters on AC vents, and it is a relatively simple process. Most modern HVAC systems are designed to accommodate filters, making installation hassle-free. However, it's essential to use the correct filter size and type recommended by the manufacturer.
How Often Do I Need to Change Out My Air Filter? Generally, most air filter manufacturers and HVAC companies recommend changing your air filter every 90 days, or 3 months. That can change based on where your home is located (ex. dusty, dry climates), if you have any pets, and the age of your system and equipment.
Can You Have Too Much Return Air? Too much return air coming through your system isn't much of an issue because the fans and ductwork working to get that air back into the system only pull with so much force to make the HVAC system work correctly.
Maintaining it properly is key, but what happens if you're caught without a replacement filter during maintenance? You might wonder about the risks of running your AC without a filter, even temporarily. The simple answer is: not for long. Ideally, your AC should never operate without a filter for more than 6-8 hours.
A return air grille also has a filter mounted on it to trap particulate matter and thus ensure that the recirculated air is more pure. This can also in the long run reduce the amount of cleaning required for ducts. Ducts for returning air are located at floor level or in the walls depending on the design of the system.
The return air vent pulls air from inside the home to recycle in the HVAC system. Pet fur and dander, smoke, and other indoor pollutants leave dirt on the vents.
cleaned simply because it seems logical that air ducts will get dirty over time and should be occasionally cleaned. Provided that the cleaning is done properly, no evidence suggests that such cleaning would be detrimental. EPA does not recommend that the air ducts be cleaned routinely, but only as needed.
Reduced airflow
A dirty filter could be to blame. When the air filter is clogged, the airflow in your HVAC system is reduced. This makes it harder for the system to keep your home at a comfortable temperature. This can lead to uneven or inadequate heating and cooling.
Use a damp microfiber cloth to wipe down the vent covers. To remove excess dirt, scrub vent covers with a soft-bristled brush and warm, soapy water. Let air dry. Use a vacuum cleaner with the crevice tool to remove any visible dirt or debris in the vents.
Why Stacking Filters is Not Recommended. Firstly, when you stack two filters, it can restrict airflow significantly. This not only hampers the efficiency of your HVAC system but can also lead to increased energy bills and potential damage to your furnace or air conditioner.
Running your AC for any time without an air filter is not recommended due to the permanent damage it can cause to the HVAC system. Dirt and dust that is normally absorbed by the filter can make its way into the AC system and wreak havoc on the mechanical components, often leading to expensive repairs.
A clogged air filter can cause more harm than good. During the day, your AC should cycle on and off, but a dirty air filter can make those cycles more frequent than they should be. Cycling is not only noisy, but it also wastes energy.
Air filters that are overdue for a change are a common cause of HVAC system failure. Over time, dirt builds up in the heating and AC filters, causing components such as the motor to go into overdrive, which may eventually overheat your unit.
While return vents don't always require filters, adding them provides additional filtration, improving indoor air quality and keeping dirt and debris out of your system.
1. Openings shall not be located less than 10 feet (3048 mm) measured in any direction from an open combustion chamber or draft hood of another appliance located in the same room or space. 2. Return air shall not be taken from a hazardous or insanitary location or a refrigeration room as defined in this code.
Symptoms include weak airflow and uneven cooling or heating throughout your home, with some rooms feeling much cooler or warmer than others. Homeowners should regularly check vents for consistent airflow. If you notice a significant drop in air pressure or uneven temperatures, it could indicate return air issues.
1. HEPA Filters. High-efficiency particulate air (HEPA) filters are recommended by the U.S. Department of Health because they are able to remove at least 99.97% of airborne allergens and pollutants — including mold spores and dust that are as small as 0.3 microns.
As the air gets sucked into your return vent, the return vent filter blocks out dust and particles from entering the airstream to your HVAC unit. Return air vent filters are sometimes preferred over using a filter in the HVAC unit for these reasons: Filters in return vents prevent dust from getting in your ductwork.
Expensive air filters are made from higher-quality materials, like fiberglass, that can last for up to 12 months. This not only saves you money, but it's also more convenient since you won't have to remember to replace your air filters as often.
