Installing an air filter in your HVAC ductwork is the best way to achieve clean, breathable air for your entire home. A tight building envelope insulates a modern home well, improving temperature control. However, it contributes to more concentrated indoor pollution. The good news is various options can compensate for this; we’ll explore a few if you’re looking for an air filter replacement or upgrade.

Residential HVAC filters are available as media filters, which provide a physical barrier to trap particles. Meanwhile, electronic filters capture various particles and contaminants via a high-voltage electric charge. Some filtration solutions combine both methods to improve their effectiveness. 

What Is a Whole-House Filter?

A whole-house filter differs from the air filter installed in your furnace or air handler unit. It is typically placed in a return-air duct. From here, it traps particles before they enter the return airflow of a forced-air heating or central AC system. Unlike traditional AC filters, a whole-house air filter must be installed professionally. 

Best Types of Ductwork Filters

A built-in filtration system can serve as a whole-house purifier. As long as your HVAC fan is on, it constantly filters the air that passes through. The effectiveness and longevity of a filter depends on the type. These are the most common air filters for HVAC ductwork in homes:

Flat Filters

Matted fiberglass filters are often found in forced-air furnaces. They’re designed to capture large dust particles before they enter ductwork and other crucial components. However, the smallest microscopic particulates can pass through. These are major culprits of respiratory irritation, so depending on your home and whether you have allergies, asthma, or other issues, these filters aren’t always the most effective.

Fiberglass filters are good at keeping large particles out of sensitive HVAC components. However, they typically don’t have a Minimum Efficiency Reporting Value (MERV) of over 4. This means their overall particle filtration ability is relatively low.

Extended Media Filters

An extended media filter is a stacked set of filtration materials. The filtration media is set in an 8-inch-thick accordion-like pile. While pleated filters with cotton or polyester folds are a step up from fiberglass filters and have MERV ratings of 5 to 8, extended media filters can have a greater range of filtration power. 

But these filters aren’t for a DIYer. They require a professional to install in line with your ductwork within a specialized filter holder. The initial installation can cost $400 to $600, according to This Old House. However, the filter needs replacement only once a year, which generally costs $60 or less.

Electrostatic Filters

An electrostatic precipitator is a hi-tech option that also integrates into ductwork. It creates static electricity, which most people prefer to avoid. Instead of making your hair frizzy and causing annoying shocks, the high-voltage current helps trap particles, which take on an electric charge so a collector plate can attract them like a magnet.

Electrostatic precipitators effectively catch extremely small particles, like smoke particles and most allergens. Another advantage is they never have to be replaced, although the aluminum collector plates must be cleaned every few months. The plates can be cleaned off by rinsing them in soap and water. 

An electrostatic filter often includes a flat or pleated carbon filter to improve efficiency. 

Electronic Filters

Instead of static electricity, electronic filters produce a high-voltage charge generated by a transformer. An electronic filter is a mechanical air filter that plugs into an outlet. It won’t work if your HVAC system has a return grille filter. Nonetheless, MERV ratings of 8 to 16 mean they’re highly effective at filtering small particles. The higher upfront price tag is offset by the need for duct filter replacement only about once a year.

Electronic filters are generally safe and effective. However, when shopping around, look for third-party testing data on any product you consider. The filter should use an ionizer process similar to a whole-home air purification system and not generate ozone, which can be a health hazard.

HEPA Filters

High-efficiency particulate air (HEPA) filters come in many forms. Some fit inside air handlers, while others are designed for ductwork. They remove 99.97% of airborne contaminants. These include tiny dust, pollen, and smoke particles as well as pet dander, mold spores, and bacteria. Whether you suffer from allergies, asthma, or other respiratory issues, a HEPA filter can eliminate the tiny particles that trigger your symptoms.

Ultraviolet (UV) Filters

A built-in UV filter uses ultraviolet light to kill microorganisms, including bacteria and viruses. Short-wave UV light effectively neutralizes organic contaminants in the airflow. However, a UV filter does not remove dust and other particulate-based pollutants. Therefore, UV and HEPA filters are often combined into the same unit. Research your options before choosing one, as some filtration systems produce ozone from oxygen molecules.

Gas-Phase Filters

Less commonly used in homes, gas-phase filters use gas sorption to attract gas molecules to a solid surface. They effectively remove odors and volatile organic compounds (VOCs). An activated carbon and charcoal media is used but a short lifespan means the filter must be replaced frequently. Also, it only removes gaseous pollutants and is ineffective against other particulates; therefore, gas-phase filters are typically used as an add-on filtration option.

FAQs

Why Do MERV Ratings Matter?

Every air filter has a MERV rating, which ranges from 1 to 16 and measures a filter’s ability to capture particles. The higher a filter’s rating, the more effectively it traps particles and the more expensive it is. 

Higher-rated filters can also reduce airflow and reduce an HVAC system’s efficiency. Therefore, filters with MERV ratings of 8 to 13 are recommended for homes. Your HVAC contractor can help find the best option for your system.

Where Are Air Duct Filters Located?

A standard HVAC filter fits in a slot above, below, or on the side of the air handling unit. Ductwork filters are placed in a return air grille in a wall or ceiling, just inside the vent. Or, they can be installed somewhere between the return duct and the air handler.

How Many Filters Does My Ductwork Need?

A small HVAC system may require just one filter. If you have a two-story home, it probably has two air filters (one for the upstairs HVAC system and one for the downstairs system). An additional filter may be needed for an indoor air quality solution like a whole-home mechanical ventilation system. An add-on ductwork filter provides additional filtration, so your heating and cooling system may have multiple filters.

How Do I Pick the Best HVAC Filter?

A pleated filter at least 3 inches thick with a high MERV rating is often considered an ideal solution. However, various factors help determine the best HVAC filter for your home. Some of these considerations include:

• Airflow: Higher-efficiency filters come with the downside of increased airflow resistance. An HVAC contractor can help find the best filter based on your system’s specifications.
• System Usage: A ductwork or whole-home air filter works only when the system is running. If you don’t need heating or cooling, you can turn on the fan setting and the filter will clean the air that circulates.
• Maintenance: If you’re looking for the lowest-cost filter, expect to change or wash it every few months. Maintenance is essential for good indoor air quality. By investing a little more, you can benefit from a media filter with fewer maintenance requirements.

Lastly, the filter’s size and design must fit your HVAC system. If not sized correctly, a filter can let air escape around its sides. This counteracts its benefits and allows contaminants in.

Ductwork transports heated or cooled air from your HVAC unit to every living space in your home. To be efficient, it must be installed properly. There are many considerations for duct replacement that, if not addressed, can lead to poor AC or furnace performance and increased energy consumption. Improper installation can also reduce indoor air quality. Below, we’ll look at best practices for ductwork replacement to avoid these issues.

Use Industry-Approved Materials

In some older homes, cavities in walls, ceilings, and floors double as airways. These are not efficient carriers of conditioned air. Air ducts must be used and can be made of sheet metal, such as galvanized steel, which is strong and durable but tough to insulate. Fiberglass is pre-insulated and easy to cut and seal but is prone to wear. Flexible non-metallic materials (plastic, fiberglass, or PVC) are common and are convenient to install in corners and other tight spaces. However, they’re prone to tearing.

An HVAC technician can help decide on the best material based on the application, your home’s layout, and its heating/cooling needs.

Consider Location and Placement

Ductwork design should never be taken for granted. When in the design phase, the following factors must be addressed:

• Duct Length: Choose the shortest possible path so ducts don’t run too far to a specific area; otherwise, your home can have hot and cold spots.
• Exposure: Exposed ducts can cause extreme temperatures to affect conditioned air and strain your HVAC system. Make sure they’re placed behind walls, above ceilings, and under floors.
• Conditioned Spaces: Whenever possible, install ducts under raised floors or in a protected space known as a chase within a home’s thermal and air barrier.

Insulate Your Air Ducts

Some ductwork may run through an unconditioned basement, garage, or attic. Consult with your HVAC contractor about the best type of insulation to use. Insulating materials can be wrapped around ducts to minimize energy loss. Otherwise, heat can escape from the ducts, making your HVAC system inefficient and reducing comfort throughout your home.

Consider the Proper Duct Size

Air ducts should be the right size for your home and your HVAC system. If they’re too small, the system won’t have enough airflow to function properly. Ducts that are too big will reduce air velocity, affecting the distribution of conditioned air. 

To avoid such issues, a contractor will follow best practices such as calculating each room’s required heating or cooling load and matching the proper duct size. To do this, they often use software that follows the Air Conditioning Contractors of America’s Manual D guidelines.

Perform Proper Duct Sealing

An HVAC installer uses various methods to seal air ducts to prevent energy loss and indoor air quality problems. Ductwork is typically attached in sections. The installation process then entails taking steps to minimize air leakage, such as:

• Connecting duct sections with screws and other fasteners.
• Sealing joints and seams with mastic or fiberglass mesh. 
• Using longer segments to reduce the number of pieces and connections needed. 
• Performing an air leakage test to ensure the system is airtight.

Make Sure the Airflow Is Balanced

An even distribution of conditioned air is dependent on having balanced airflow. Air balancing requires the supply and return ducts to have the same capacity, which yields neutral air pressure. It also requires having the appropriate number of supply and return registers throughout your home. This is why you need a professional who is experienced in ductwork design. 

Proper air balancing can:

• Maintain an optimal comfort level
• Improve your HVAC system’s energy efficiency
• Increase the lifespan of AC and heating equipment
• Prevent mold and other indoor air quality issues
• Avoid high energy bills and repair costs

When it comes to maintaining a healthy and efficient HVAC system, one of the crucial tasks is keeping the air ducts clean. Many homeowners ponder, “Can you clean your own air ducts?” While it’s possible to perform some basic cleaning yourself, it’s highly recommended to get professional air duct cleaning services for a thorough job. This blog explores the DIY approach versus professional cleaning for air ducts.

The Basics of DIY Duct Cleaning

Cleaning your air ducts can be a straightforward task if you’re addressing only the accessible parts. For DIY duct cleaning, a standard household vacuum with brush attachments can help remove dust and debris from the air duct covers and the visible parts of the ductwork.

Tools Required for DIY Cleaning

If you want to know how you can clean your own air ducts, you’ll require a few tools. For a basic clean, you’ll need a vacuum cleaner, microfiber cloths, a soft-bristled brush, and perhaps a screwdriver to remove vent covers. It’s also wise to have a dust mask and gloves to protect yourself from all that dust.

Steps for DIY Air Duct Cleaning

Sure, you can clean your own air ducts to a certain extent — but you should always put safety first. Begin by turning off your HVAC system at the breaker panel or service switch. Then, remove the vent covers and use the vacuum hose to suck up as much dust as you can from the exposed ductwork. Wipe down the vent covers with a damp microfiber cloth repeatedly and let them air dry before reattaching.

Limitations of DIY Air Duct Cleaning

While you can clean your air ducts yourself to some extent, DIY cleaning has its limitations. It typically addresses only the surface dust and doesn’t clean deeper into the duct system where more cleaning might be necessary.

Inadequate Equipment

A standard household vacuum may not have the power to remove built-up dust and debris deep within the duct system. Professional duct cleaning services use high-powered vacuum systems and specialized tools to thoroughly clean the entire system.

Risk of Damage

Without the proper knowledge and tools, there’s a risk of damaging your ductwork. Professionals know how to navigate various types of duct systems, including those in hard-to-reach places like crawl spaces, without causing harm.

This blog dives deep into the ins and outs of air duct maintenance, the telltale signs to watch for, and the benefits of keeping those ducts dust-free.

Why Air Duct Cleaning Matters

Before we discuss how often you should clean your air ducts, it’s important to understand the ‘why’ behind it.

1. Indoor Air Quality: Over time, air ducts can accumulate significant amounts of dust, mold spores, and other pollutants. This impacts indoor air quality, which can, in turn, affect the health and comfort of inhabitants.
2. Efficiency of HVAC Systems: A layer of dust and debris in your air ducts can restrict airflow. This means your heating and cooling system needs to work harder, leading to increased energy costs and reduced efficiency.
3. Preventing Mold Growth: Moisture can lead to visible mold growth in air ducts. Mold spores can then circulate throughout your home, posing health risks.

Determining the Right Time: When Should You Clean Your Air Ducts?

The National Air Duct Cleaners Association (NADCA) recommends cleaning your air ducts every three to five years. However, several factors could necessitate more frequent air duct cleanings, such as having pets, living in an area with a high pollen count, or living in areas with high humidity levels. Here are some significant factors to consider when determining when you should clean your air ducts.
