Healthy Indoor Air Quality Starts With Your HVAC Filter

Air filters are most effective at capturing particles in the interior air; however, they eventually get clogged. Many people don’t change the HVAC filters as often as the system requires, leading to severe problems.

After reading this article, you will get a better understanding of the importance of HVAC air filters to produce better air quality. Keep reading about the consequences of ignoring HVAC filter changes.

What Happens If You Ignore HVAC Filter Changes?

Health Issues 

Air filters get dirty over time and must be changed during every off-peak season. You have to be more considerate about changing the air filters than others if you own pets and have family members with respiratory difficulties. You must remove the dirty filter and install a new one to prevent health problems, including eye and throat irritation, infection, heart disease, headaches, asthma, etc.

Bad Indoor Air Quality 

Homes should be our most comfortable zone as we spend maximum hours there. Poor indoor air quality cannot allow you to stay relaxed. A dirty HVAC filter cannot trap air allergens and moisture effectively, resulting in unpleasant mold and bacteria growth. The microscopic air particles spread into the system and cause severe health issues to the family members.

Damage to the HVAC System 

A dirty filter leads to overheating and freezing out off and on, causing premature wear out of the HVAC system. The air cannot move freely through a dirty filter. As a result, the HVAC system has to fulfill the high energy demand of the filter, which causes damage to the system. Changing the air filter will help you to prevent HVAC system damage.

Inconsistent Air Temperature 

Air filters must be changed frequently during the off-peak season. If left unchecked, you will suffer inside your house due to inconsistent air temperature. When the HVAC systems have to work harder to blow air, some areas of your home may get hotter or cooler than you want. If you don’t want your HVAC filter to interfere with the air temperature sensors, consider changing the air filters on time.

High Energy Bills 

Dirty or clogged air filters cannot produce adequate airflow throughout the house and filter out air pollutants. When the air cannot circulate through the system efficiently, it forces the HVAC system to work harder to balance your home’s temperature. Hence, you have to count higher energy bills at the end of the month.

How Frequently Should You Change Your HVAC Filter?

You are responsible for determining how often you need to replace your HVAC filters by considering the needs of your HVAC system, the types of air filters you use, and the frequency with which you utilize the filters. You should talk to a specialist to know the replacement requirements of the filter you will use.

Check out the manufacturer’s labeling or website to get ideas about the replacement for the particle HVAC filter. The system’s documentation will help you to identify the right type and size of filter needed for your house for example 7.75×25.75×1 air filter and 11.25×19.25×1 air filter. So you can easily determine the frequency of replacing your HVAC filters.


In many houses, residential air filters are often overlooked HVAC system components. Many people tend to avoid the change of dirty air filters, which eventually lead to the system’s damage and costly repairs. Custom Filters Direct offers the best air filters for every HVAC system at a minimal cost. If you find it difficult to replace the filter on your own, hire a professional residential air filters supplier to help you to choose the most suitable air filter for your home whenever you need it.
