Indoor air might look like it’s fresh and clean, but, if you look closely, it may have tiny particles mixed in with it. You might’ve noticed this in direct sunlight. These particulates are only micrometers in size, so they can go inside narrow entrances easily. We breathe these particles without noticing, and they go deep into our lungs. Unfortunately, these pollutants can cause your health to deteriorate.

The HVAC air filters in your heating and air conditioning system can help improve your indoor air quality. These air filters block the particulate matter from entering your home and the air that you breathe. However, they might not work as they should. This article will discuss the different reasons your HVAC filter is not improving your indoor air quality.

7 Reasons Your Filter Isn’t Improving Your Indoor Air Quality

Your home’s HVAC filter might be underperforming due to the following:

1. No HVAC Filter

Did you recently move? If so, the HVAC system is most likely in tiptop shape, and all the parts are accounted for. However, you might also have noted that there are excess dust and other particulates in the air. Check if the filters are in place in the HVAC unit. The previous homeowner might have forgotten to put the filter in. Without a filter, the contaminants pass through easily. This will lead to a lot of dust and dirt accumulation in your system’s coils, ducts, blowers, and home.

2. Incorrect HVAC Filter Installation

Having an HVAC filter alone is not enough to improve your indoor air quality if it is not installed correctly. Consequently, your high-quality air filter will not work as effectively. A small opening is enough for the particulates to go around the air filter. Therefore, despite having an air filter in place, the indoor air quality will still suffer. You can replace it as per the manufacturer’s recommendation. However, your home’s air quality will not improve unless you do something about installing the air filter properly. Contact your trusted HVAC technician to help you fix this issue.

3. Insufficient HVAC Unit Runtime

Filters are static installations. Therefore, air needs to flow from one side to the other for it to work as it should. The HVAC system needs to have enough runtime to force an adequate amount of air through the filters.

An HVAC system that is too large can short cycle. This means that it reaches the set temperature quicker, so the system switches off immediately. The HVAC system does not run long enough for the filter to do its job correctly. Ensure that a professional HVAC technician installs the correct HVAC size for your home. Check the fan settings of your thermostat as well. Make sure that it is “ON” instead of “AUTO” so that it runs longer. If you are not satisfied with this, try a standalone air filter. Discuss your issues with an expert so you can further improve your indoor air quality.

4. Insufficient HVAC Airflow

Sometimes, your HVAC runs sufficiently, but there isn’t enough airflow. As a result, the filtration volume decreases. This issue is usually caused by undersized return ducts and dirty air filters. The latter happens when homeowners do not subscribe to a regular HVAC filter replacement schedule. Air cannot pass through easily if the filter is clogged. When this happens, airflow will decrease and air pressure will increase. System efficiency will also be affected negatively. Make sure to change the filters frequently so that it can do its job properly.

5. Low MERV Rating

The Minimum Efficiency Reporting Value, or MERV, is the filter’s ability to capture particles. The higher the rating, the better it can trap certain types of particles. Therefore, you must pay attention to what MERV rating your filter has. Those with low ratings might be cheaper, but it also means that they are not as effective as those with higher MERV ratings. Consider this the next time you are buying filters. It is worth investing in filters with high ratings if it means you and your family breathe cleaner air when indoors.

6. Failure To Filter Outdoor Air For Mechanical Ventilation

HVAC systems will only work at its best if they are installed correctly. It won’t matter if you have a good HVAC brand if the installers make an installation mistake. For instance, the outdoor air duct might have been connected to the system’s return side. This bypasses the air filter. This mistake does not happen often, but it doesn’t mean it can’t happen to you. A highly trained and experienced technician can fix this problem immediately.

7. Incorrect Filter Placement

It is essential to know how your HVAC unit works and how the air flows. This way, you can determine the correct place to put your air filter. Incorrect or sub-optimal filter placement will lead to poor performance. This might seem like a little thing, but even the best HVAC make and model can underperform when it is in the wrong location.


The air filter is essential in achieving high indoor air quality. If you notice frequent respiratory issues like coughs and sneezes in your family, you might want to look into the air filter of your HVAC unit. It might have one or more of the problems listed above. Prevent any issues by hiring a reliable HVAC contractor to assist you. Make sure that your system receives regular checks and maintenance as well so that you breathe in clean indoor air at all times.

healthy indoor air quality at home

Air pollution is typically associated with dirt from factories, car exhaust, and many other factors that lower the quality of outdoor air. However, contamination can also occur indoors, which many people fail to realize.

It is necessary to give indoor air pollution attention since the average person usually spends most of his or her time indoors. You have many ways to enhance the quality of indoor air for the sake of your loved ones.

What Does Indoor Air Quality Entail?

We can define indoor air quality as the condition of the air we breathe when we spend time within a structure. The health and wellbeing of different people can be affected by the quality of the air. Air quality can affect their comfort and mood. Alarming studies show that there is more contaminated air indoors than outdoors. Researchers blame current structure construction practices.

Construction practices now build more airtight structures with the hope of meeting higher energy efficiency standards. However, as we lower energy consumption, we end up losing fresh, natural ventilation. Consequently, irritants that are trapped inside the home build up over time to dangerous levels. Ducts recirculate dust, dirt, dander, and other pollutants at ever-increasing rates.

Factors Causing Poor Air Quality

A variety of factors that relate to lifestyle cause indoor air pollution. For instance, many households keep pets for security, companionship, among other benefits. These animals tend to generate a lot of dander and fur that can trigger allergies. Also, walls, covered in paint, can release volatile organic compounds.

Additionally, dust and dirt particles can get inside through footwear and HVAC units. Furthermore, persistent moisture can favor the growth of mold and mildew. Also, household chemicals we use can aggravate indoor air quality issues.

Effects Of Poor Quality Indoor Air

All homeowners ought to be attentive to the matter of air pollution, lest they suffer consequences of poor indoor air quality. Members of different families may begin exhibiting different signs of respiratory conditions such as asthma, constant coughs, and breathing difficulties. Besides, they can also experience digestive issues and chronic fatigue. The worst possible case of unclean indoor air is contracting cancer.

Ways HVAC Ductwork Affects Indoor Air Quality

The cooling and heating system uses ductwork to circulate air. If the network has pollutants, then the circulation will be full of contaminated air.

The contaminated air will affect people in the household unless they take some corrective measures. Therefore, you need to raise the indoor air quality standard in your home.

How Can My HVAC System Better My Indoor Air Quality?

1. HVAC Air Filters

HVAC systems have air filters that trap pollutants from the air. However, when dirt particles accumulate on the surfaces of the filters, they eventually interfere with airflow which leads to inefficiency. To prevent this from occurring, you should clean them periodically and replace them. A monthly inspection ought to determine if it is time for a replacement.

2. UV Lights

The UV light can cause harmful effects to people, but you can harness them for health benefits as solutions to indoor air pollution. Ultraviolet light destroys viruses, mold, bacteria, and other pathogens. The UV light can fix unwanted pathogens merely through a short exposure. It can be quite beneficial to install UV lamps strategically across your HVAC system. You can learn more by talking to your HVAC contractor.

3. HVAC Dehumidifiers And Humidifiers

It is essential to control the level of humidity because it can drastically affect your indoor comfort. During winter, indoor humidity can fall, and dry air may cause serious respiratory issues. A humidifier can be used to control the problem. When the humidity rises in summer, it creates the perfect conditions for pathogens, mold, and other tiny harmful organisms. You can use a dehumidifier to control and fix the problem.

Modern HVAC systems control the amount of moisture in your house. If you possess an old HVAC unit, you need to replace it with a modern model that has the feature of controlling indoor humidity. Talk to your HVAC Company for more details.

4. HVAC Ductwork Inspections

As already mentioned, ducts channel indoor air where necessary. They pump air in every room of the house to keep everyone comfortable. The ductwork should be inspected often to keep the system clean and ensure it is free from pollutants.

A leak in the ductwork system can be a route for pollutants to enter the HVAC system. Consequently, the HVAC system distributes these pollutants in the air that people breathe indoors. You require regular maintenance of your ductwork if you have a forced-air HVAC system. Ensure you schedule an inspection of the ductwork with your trusted HVAC contractor today.
